最新市场现状
根据国家统计局公布数据,2014年1~12月全国铅酸蓄电池行业累计完成产量同比增长4.58%。其中:12月份完成产量同比增长-7.87%。 [2] 
分类
常用的铅酸蓄电池主要分三大类: 1)普通蓄电池;普通蓄电池的极板是由铅和铅的氧化物构成,电解液是硫酸的水溶液。它的主要优点是电压稳定、价格便宜;缺点是比能低(即每公斤蓄电池存储的电能)、使用寿命短和日常维护频繁。
普通蓄电池特性    
1. 高容量    2. 长寿命
3. 高CCA,起动性能好    4. 充电接受及耐振动性能优越
5. 优质的复合玻璃纤维隔板应用    6. TTP技术应用

2)干荷蓄电池:它的全称是干式荷电铅酸蓄电池,它的主要特点是负极板有 2V铅酸蓄电池 2V铅酸蓄电池 较高的储电能力,在完全干燥状态下,能在两年内保存所得到的电量,使用时,只需加入电解液,等过20—30分钟就可使用。 3)免维护蓄电池:免维护蓄电池由于自身结构上的优势,电解液的消耗量非常小,在使用寿命内基本不需要补充蒸馏水。它还具有耐震、耐高温、体积小、自放电小的特点。使用寿命一般为普通蓄电池的两倍。市场上的免维护蓄电池也有两种:第一种在购买时一次性加电解液以后使用中不需要维护(添加补充液);另一种是电池本身出厂时就已经加好电解液并封死,用户根本就不能加补充液. 铅酸电池有2伏,4伏,6伏,8伏,12伏,24伏等系列,容量从200毫安时到3000安时。VRLA电池是基于AGM(吸液玻璃纤维板)技术和钙栅板的可充电电池,具有优越的大电流放电特性和超长的使用寿命。它在使用中不需加水。
VRLA电池
VRLA电池(ValveRegulatedLeadAcidBattery)用途广泛,可用在电动工具,应急灯,UPS,电动轮椅,计算机和通讯设备等方面。 VRLA电池是这样设计的:在电池中,一部分数量的电解液被吸收在极片和隔板中,以此增加负极吸氧能力,阻止电解液损耗,使电池能够实现密封。
Parts组件    材料    作用
正极    正极为铅-锑-钙合金栏板,内含氧化铅为活性物质    保证足够的容量 长时间使用中保持蓄电池容量,减小自放电
负极    负极为铅-锑-钙合金栏板,内含海绵状纤维活性物质    同上
隔板    先进的多微孔AGM隔板保持电解液,防止正极与负极短路。隔板采用无纺超细玻璃纤维,在硫酸中化学性能稳定。多孔结构有助于保持活性物质反应所需的电解液    防止正负极短路 保持电解液 防止活性物质从电极表面脱落
电解液    在电池的电化学反应中,硫酸作为电解液传导离子    使电子能在电池正负极活性物质间转移
外壳和盖子    在没有特别说明下,外壳和盖子为ABS树脂    提供电池正负极组合栏板放置的空间 具有足够的机械强度可承受电池内部压力
安全阀    材质为具有优质耐酸和抗老化的合成橡胶。帽状阀中有氯丁二烯橡胶制成的单通道排气阀    电池内压高于正常压力时释放气体,保持压力正常 阻止氧气进入
端子    根据电池的不同,正负极端子可为连接片、棒状、螺柱或引出线。端子的密封为可靠的粘结剂密封。 密封件的颜色:红色为正极,黑色为负极    密封端子有助于大电流放电和长的使用寿命
电极中的电化学反应 阀控铅酸电池的电化学反应式如下所示。充电是将外部直流电源连在蓄电池上进行充电,使电能转化成化学能储存起来。放电是电能从电池中释放出来去驱动外部设备。 当VRLA蓄电池充电将达到顶点时,充电电流只被用来分解电解液中的水,此时,电池正极产生氧气,负极产生氢气,气体会从蓄电池中溢出,造成电解液减少,需不定时加水。 另一方面,充电末期或过充条件下,充电能量被用来分解水,正极产生的氧气与负极的海绵状铅反应,使负极的一部分处于未充满状态,拟制负极氢气的产生。
主要特性
安全密封 在正常操作中,电解液不会从电池的端子或外壳中泄露出。 没有自由酸 特殊的吸液隔板将酸保持在内,电池内部没有自由酸液,因此电池可放置在任意位置。 泄气系统 电池内压超出正常水平后,VRLA(Valve-Regulated Lead Acid Battery即“阀控式密封铅酸蓄电池”的缩写)电池会放出多余气体并自动重新密封,保证电池内没有多余气体。 维护简单 由于独一无二的气体复合系统使产生的气体转化成水,在使用电池的过程中不需要加水。 使用寿命长 采用了有抗腐蚀结构的铅钙合金栏板,电池可浮充使用10-15年。 质量稳定,可靠性高 采用先进的生产工艺和严格的质量控制系统,电池的质量稳定,性能可靠。电压、容量和密封在线上进行100%检验。 铅酸蓄电池生产工艺 配合金--铸板栅--涂片(之前应有制铅粉--和膏过程)--固化、干燥--分片打磨--配组--包片--极群焊接--装壳--上盖密封--端子焊接--入槽--注酸---化成--清洗--入库---包装发货
使用方法
(1)切勿短路电池。当电池的正负极通过外部物质实现电接触,电池就短路了,例如放在口袋中的无外包装电池就会因与钥匙或硬币等金属材料接触而产生短路。 (2)正确安装电池,使电池的极性标记(“+”和“-”)和用电器具的标记正确对应。如果电池被不正确地反向安装到用电器具中,则可能发生短路或充电,导致电池温度的迅速升高。 (3)不要试图对电池充电。对不能充电的原电池进行充电,会使电池内部产生气体和热量。 (4)不要对电池强制放电。电池被强制放电时,其电压将会低于设计性能并在电池内部产生气体。 (5)不要加热或直接焊接电池。电池被加热或焊接时,热量会造成电池内部发生短路。 (6)不要拆解电池。电池被拆解或分开时,电池组分之间有可能发生接触,从而导致短路。 (7)不要将新旧电池或是不同型号、品牌的电池混用。当需要更换电池时,应同时用同品牌、同型号、同批次的新电池更换所有的电池。当不同品牌和型号的电池或是新旧不同的电池共同使用时,由于不同电池之间电压或容量的不同,部分电池会发生过放电。 (8)不要使电池变形。不要对电池进行挤压、戳穿或其他形式的损伤,这些滥用往往会导致电池发生短路。 (9)不要将电池放入火中。将电池放入火中时,热量的集聚会导致爆炸和人身伤害,除了合适的可控制的焚烧处理方式外,不要试图烧毁电池。 (10)不要让儿童接触电池或是在没有成人监督的情况下更换电池。那些有可能被吞咽的电池应尽量避免让儿童接触,特别是那些能放入图中所示的摄食量规内的电池。一旦某人摄食了电池,应立即寻求医生帮助。 (11)不要密封或改变电池。密封电池或是其他形式的改变电池,会使电池的安全阀被堵塞,从而当电池内部产生气体时不能及时排出。如果认为必须改变电池,则应尽量获得制造商的建议。 (12)对于不用的电池,应以它们的原始包装进行保存,并尽量远离金属物质,如果包装已打开,则应有序排放,不要混乱堆放。无包装的电池和金属物质混放在一起时,有可能使电池发生短路。避免这种情况发生的最好办法就是使用它们的原始包装来保存不用的电池。 (13)除非是用于紧急情况,对于长期不用的电池应尽量从用电装置中取出。当一个电池达不到满意的效果或是可以预计长期不使用,则将其从装置中取出是有益的,尽管目前市场上的电池都带有保护性外壳或是以其他方式来控制漏液,但是一个部分或是完全用完的电池还是会比一个没用过的电池更容易漏液。 [3]

放电剩余
电量计算 大多数使用VRLA的场合都需要在放电过程中得知剩余电量信息,此信息可能用百分比或剩余工作时间等方式表示。在蓄电池电量耗尽前需要完成某些操作,关停设备或启动其它发电设备。完全充电后的VRLA的放电剩余电量与电池的劣化程度有关,还与放电的电源大小、温度相关,尤其是在高倍率下。 与SOC相关的研究主要集中在电动汽车(EV-Electrical Vehicle)的“油料表”(Gauge),它必 须准确指示剩余电量,以便及时充电,而EV的变电流使用方式和刹车电量回授的影响使得SOC的计算更为复杂。 SOC计算方法有以下几种。 (1) 电压—电量对应 世界最大的电池电量仪表制造商CURTIS公司的产品,部分使用电压—电量对应方法。 (2) 安时积分法 针对电动汽车的电池使用特点,研究了计算补偿系数的电量计量方法。 (3)Peukert定律 一种计算在不同电流和温度下放电容量的方法,其系数的确定较为困难。对于劣化到一定程度的电池,该定律是否仍然有效,还没有相关证实。 (4) 阻抗分析 Kenneth Bundy等人进行了通过阻抗谱数据的分析预测镍氢(Ni/MH)电池的SOC,获得了最大误差为7%的预测效果;Alvin J.Salkind等采用模糊逻辑算法,分析3个不同频点的阻抗虚部预测Li/SO2和Ni/MH电池的SOC亦获得5%的准确度。 (5) 复合技术 部分研究是采用以上几种方法的复合。 由于备用方式与循环深度放电使用方式存在本质的区别,如何计算备用方式的SOC受劣化程度的影响仍是难题。

Latest market status

According to the data released by the National Bureau of Statistics, the cumulative output of the national lead-acid battery industry increased by 4.58% year-on-year from January to December 2014. Among them, the finished output in December increased by - 7.87% year on year. [2]

classification

Common lead-acid batteries are mainly divided into three categories: 1) ordinary batteries; The plate of ordinary battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; The disadvantages are low specific energy (i.e. the electric energy stored per kilogram of battery), short service life and frequent daily maintenance.

General battery characteristics

1. High capacity 2 Long life

3. High CCA, good starting performance 4 Superior charging acceptance and vibration resistance

5. Application of high-quality composite glass fiber partition 6 TTP technology application

7. Advanced anti-sulfation technology 8 Advanced low-antimony alloy technology, less maintenance design

9. Reliable liquid hole plug sealing design 10. Dry load design, long storage period, ready to use

11. Complete models, beautiful and generous, high standard design

2) Dry-charged battery: its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a high storage capacity of 2V lead-acid battery and 2V lead-acid battery. In a completely dry state, it can store the energy obtained within two years. When it is used, it only needs to add electrolyte, and it can be used after 20-30 minutes. 3) Maintenance-free battery: Due to its structural advantages, the consumption of electrolyte is very small, and it is basically unnecessary to supplement distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size and small self-discharge. The service life is generally twice that of ordinary batteries. There are also two types of maintenance-free batteries on the market: the first type is to add electrolyte at the time of purchase without maintenance (add supplemental solution); The other is that the battery itself has been filled with electrolyte and sealed when it leaves the factory, so the user can't add the supplemental solution at all Lead-acid batteries have 2 V, 4 V, 6 V, 8 V, 12 V, 24 V series, and the capacity ranges from 200 mAh to 3000 Ah. VRLA battery is a rechargeable battery based on AGM (liquid-absorbing glass fiber board) technology and calcium grid plate, which has excellent high current discharge characteristics and long service life. It does not need to add water in use.

VRLA battery

VRLA battery (ValveRegulated Lead Acid Battery) has a wide range of uses, and can be used in power tools, emergency lights, UPS, electric wheelchairs, computers and communication equipment. The VRLA battery is designed as follows: in the battery, a part of the electrolyte is absorbed in the electrode plate and separator, so as to increase the oxygen absorption capacity of the negative electrode, prevent the loss of electrolyte, and enable the battery to achieve sealing.

Parts component material function

The positive pole is a lead-antimony-calcium alloy fence, containing lead oxide as active material to ensure sufficient capacity to maintain the battery capacity and reduce self-discharge during long-term use

The negative electrode is a lead-antimony-calcium alloy fence plate containing spongy fibrous active substances as above

The advanced microporous AGM separator keeps the electrolyte and prevents short circuit between positive and negative electrodes. The separator is made of non-woven ultra-fine glass fiber, which has stable chemical properties in sulfuric acid. The porous structure helps to maintain the electrolyte required for the reaction of the active substance to prevent the short circuit between the positive and negative electrodes. The electrolyte keeps the active substance from falling off the electrode surface

Electrolyte In the electrochemical reaction of the battery, sulfuric acid acts as the electrolyte to conduct ions so that electrons can be transferred between the positive and negative active substances of the battery

Unless otherwise specified, the shell and cover provide ABS resin with the space for the battery positive and negative pole combination board to be placed with sufficient mechanical strength to withstand the internal pressure of the battery

The safety valve is made of high-quality acid resistant and anti-aging synthetic rubber. The cap valve has a single-channel vent valve made of chloroprene rubber in it. When the internal pressure of the battery is higher than the normal pressure, the gas is released to keep the pressure normal and prevent oxygen from entering

According to the difference of the battery, the positive and negative terminals can be connecting pieces, rods, studs or outgoing lines. The terminal is sealed with reliable adhesive. The color of the seal: red is the positive pole, and black is the negative pole. The sealed terminal is conducive to high current discharge and long service life

The electrochemical reaction formula of the valve regulated lead acid battery in the electrode is as follows. Charging is to connect the external DC power supply to the battery for charging, so that electrical energy can be converted into chemical energy for storage. Discharge is the release of electrical energy from the battery to drive external equipment. When the VRLA battery is about to reach the peak of charging, the charging current is only used to decompose the water in the electrolyte. At this time, the positive pole of the battery generates oxygen, the negative pole generates hydrogen, and the gas will overflow from the battery, resulting in the reduction of the electrolyte. It is necessary to add water from time to time. On the other hand, at the end of charging or under overcharge conditions, the charging energy is used to decompose water, and the oxygen generated by the anode reacts with the spongy lead of the anode, leaving a part of the anode in an unfilled state, thus simulating the generation of hydrogen in the anode.

Main characteristics

Safety seal During normal operation, the electrolyte will not leak from the battery terminal or shell. There is no free acid special liquid absorption separator to keep the acid inside, and there is no free acid inside the battery, so the battery can be placed at any position. After the internal pressure of the vent system battery exceeds the normal level, the VRLA (Valve-Regulated Lead Acid Battery) battery will release excess gas and automatically reseal to ensure that there is no excess gas in the battery. Simple maintenance Due to the unique gas composite system, the generated gas is converted into water, and no water is needed during the use of the battery. The lead-calcium alloy fence with anti-corrosion structure is used for long service life, and the battery can be used for floating charge for 10-15 years. Stable quality and high reliability Advanced production technology and strict quality control system are adopted to ensure stable quality and reliable performance of battery. The voltage, capacity and sealing shall be 100% inspected on the line. Lead-acid battery production process: alloy matching -- casting grid -- coating (there should be lead powder before -- paste mixing process) -- curing, drying -- slice grinding -- group matching -- sheet wrapping -- pole group welding -- shell -- upper cover sealing -- terminal welding -- slot -- acid injection -- formation -- cleaning -- warehousing -- packaging and delivery

usage method

(1) Do not short-circuit the battery. When the positive and negative poles of the battery are electrically contacted by external materials, the battery will be short-circuited. For example, the battery without outer packaging placed in the pocket will be short-circuited due to contact with metal materials such as keys or coins. (2) Correctly install the battery so that the polarity marks ("+" and "-") of the battery correspond correctly with the marks of the electric appliance. If the battery is incorrectly installed in the electrical appliance in the reverse direction, a short circuit or charging may occur, resulting in a rapid increase in battery temperature. (3) Do not attempt to charge the battery. Charging the primary battery that cannot be charged will generate gas and heat inside the battery. (4) Do not force the battery to discharge. When the battery is forced to discharge, its voltage will be lower than the design performance and gas will be generated inside the battery. (5) Do not heat or weld the battery directly. When the battery is heated or welded, the heat will cause a short circuit inside the battery. (6) Do not disassemble the battery. When the battery is disassembled or separated, there may be contact between battery components, resulting in short circuit. (7) Do not mix new and old batteries or batteries of different models and brands. When batteries need to be replaced, all batteries should be replaced with new batteries of the same brand, model and batch. When batteries of different brands and models or new and old batteries are used together, some batteries will be over-discharged due to the difference of voltage or capacity between different batteries. (8) Do not deform the battery. Do not crush, puncture or other forms of damage to the battery. These abuses often lead to short circuit of the battery. (9) Do not put the battery in the fire. When the battery is put into the fire, the heat gathering will lead to explosion and personal injury. In addition to proper and controllable incineration treatment, do not attempt to burn the battery. (10) Do not let children touch the battery or replace the battery without adult supervision. Those batteries that may be swallowed should be kept away from children as much as possible, especially those that can be put into the food intake gauge shown in the figure. Once someone has ingested the battery, seek medical help immediately. (11) Do not seal or change the battery. Sealing the battery or changing the battery in other forms will cause the safety valve of the battery to be blocked, so that the gas generated in the battery cannot be discharged in time. If it is deemed necessary to change the battery, the manufacturer's recommendation shall be obtained as far as possible. (12) Unused batteries should be stored in their original packaging and kept away from metal substances as far as possible. If the packaging has been opened, they should be discharged in order and not stacked in disorder. Unpacked batteries and metal materials may cause short circuit when mixed together. The best way to avoid this is to use their original packaging to save unused batteries. (13) Unless it is used in an emergency, the batteries that are not used for a long time should be removed from the electrical device as far as possible. When a battery cannot achieve satisfactory results or can not be expected to be used for a long time, it is beneficial to remove it from the device. Although all batteries on the m
