Q-Batteries铅酸蓄电池的优缺点
What is lead-acid battery
Lead-acid battery is also called lead-acid water battery. Its electrode is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and affordable price; The main disadvantages are low specific energy (i.e. the electric energy stored per kilogram of battery), short service life and frequent daily maintenance. The general life of the old battery is about 2 years. At the same time, it is necessary to regularly check the height of the electrolyte and add distilled water. However, with the progress of technology, the life of the general battery has become longer and the maintenance is simpler.
Since its creation and invention in 1958, lead-acid batteries have been used and developed for more than 100 years. They are widely used in the power end of diesel locomotives. Because lead-acid batteries used in new energy vehicles need to provide power for vehicles, their main development direction is to improve specific energy and increase the cycle life.
Advantages of lead-acid battery
Lead-acid battery is the battery with the longest manufacturing time and the most mature technology, with stable performance, reliability and good applicability. The characteristics of the electrolyte of the battery make the lead-acid battery non-flammable. In addition, the battery is designed with normal pressure and low pressure, and the safety is good. It can be used for floating charging and has excellent performance of shallow charging and shallow discharging, which is more suitable for UPS, new energy storage, peak shaving and valley filling of power grid, etc; The large-capacity battery technology is mature and can be made into thousands of ampere-hours battery, which provides convenience for large-scale energy storage.
Lead-acid battery has become the most cost-effective secondary battery. With the same energy, the price of lead-acid battery is about one third of that of lithium-ion battery or nickel-hydrogen battery. Moreover, lead-acid batteries also have recycling value. The combination of lead-acid batteries is simple and clear, the regeneration technology is mature, and the recycling value is high.
Disadvantages of lead-acid battery:
1. Long charging time;
2. Lead is a heavy metal with pollution, which runs counter to the concept of new energy powered vehicles.
3. The specific energy is low, and the overall mass and volume required for new energy vehicles are very large, and the development process of driving on one charge is shorter;
4. The service life is short, and the later application cost is relatively high;
Which is better, lead-acid battery or lithium battery
1. The battery price of an electric vehicle is half. Lithium battery is much more expensive than lead-acid battery, and lithium battery is also much more expensive.
2. The lithium-ion battery has a long service life and quality, which means long battery life. It can run far than lead-acid battery.
3. Personally, I think that although there are lithium trams on sale now, the sales volume is not ideal and is not recognized by the public. In terms of ecological environment protection, lithium battery is more environmentally friendly than lead acid.
什么是铅酸蓄电池
铅酸蓄电池又称之为铅酸水电池，它的电极是由铅和铅的氧化物构成，电解液是硫酸的水溶液。主要优点是电压稳定、价格实惠;主要缺点比能低(即每公斤蓄电池存储的电能)、运用寿命短和日常维护频繁。旧式一般蓄电池一般寿命在2年左右，同时需定期检查电解液的高度并加上蒸馏水。只不过伴随着科技的进步，一般蓄电池的寿命变得更长同时维护也更简单了。
铅酸蓄电池自1958年创造发明以来，其运用和发展已经有了100多年的历史，其广泛运用于内燃机车的动力端，而新能源汽车所运用的铅酸蓄电池因为需要为车辆提供动力，因此它的主要发展方向是提高比能量，增大循环使用的寿命。
铅酸蓄电池的优点
铅酸电池是完成技术生产制造时间最长，技术最成熟的电池，性能稳定、可靠、适用性好。电池本身的电解液特性使得铅酸电池无可燃性，加上电池选用常压和低压设计，安全性好。能浮充电运用，浅充浅放电性能优异，比较适用于不间断电(UPS)、新能源储能、电网削峰填谷等领域;大容量电池技术成熟，能制成数千安时的电池，为大规模储能提供了便利。
铅酸电池变成了最物美价廉的二次电池，在相同能量的情况下，铅酸电池的价格大概是锂离子电池或镍氢电池的三分之一。且铅酸电池本身也拥有回收利用价值，铅酸蓄电池组合而成简洁明了，再生技术成熟，回收利用价值高。
铅酸蓄电池的缺点：
1、充电时间长;
2、铅是重金属，存在污染，与新能源动力车的概念背道。
3、比能量低，在新能源汽车重所需要占用的整体质量以及体积非常大，一次充电可行驶的发展历程短一些;
4、运用寿命短，且后期运用成本相对高;
铅酸蓄电池和锂电池相比哪一个好
1.一辆电动汽车的电池价格是一半，锂电池比铅酸电池贵些很多，锂电池也贵些很多。
2.锂电池的寿命长、质量上也就是续航时间长，比得上铅酸电池跑得远。
3.我个人认为现在尽管已经有锂电车在卖，可是销量并不理想，不被大众认可。就生态环境保护来讲，锂电池比铅酸更环保。
