电动车锂电池和铅酸蓄电池哪种好                                        

                                                        铅酸电池优缺点

*性价比高 一般认为电动车用铅酸电池比锂电池要好，主要是因为铅酸电池更安全，价格相对便宜，大众更容易接受，

最重要的是铅酸电池回收价格比锂电池更高。

*高倍率放电性能更好  一般来说，一组铅酸电池只要几百块，一组锂电池，随随便便的就要一千多近两千块。铅

酸电池过载能力和抗冲击能力强，电动车行驶中的阻力，随时变换，甚至突然被停止，这时电池电流变化很大的，

在打火那几秒钟，电流达两三百安培，铅酸电池能安然无恙，而锂电池则是难望其项背。

*铅酸电池也有缺点  比如重金属容易造成环境污染;与锂电池相比，铅酸电池能量密度更低;而且其使用寿命不 

及锂电池。

                                                             锂电池优缺点

*能效高 锂电池无论是体积比能量，还是重量比能量，锂电池均比铅酸蓄电池高出3倍以上。锂电池体积更小，重量更轻、循环寿命长。

*轻便环保  锂电池相对轻巧，携带方便，而寿命相对要长很多。此外，锂电池的高低温适应性更强，受温度影响 

因素较小，且更加绿色环保。

*锂电池也有三个缺点 其安全稳定性相对而言比较差，要是操作不当，很容易发生爆炸的风险。另外，锂电池不

能大电流放电目生产要求条件高，成本更高。

                                                                     小结

以目前而言，锂电车市场普及率低干铅酸电池车，其主要的因素是技术的不完善，锂电池成本仍相对偏高。因此

在现有“锂电车”产品设计中，多采用减少锂电池的容量配置，来相应降低整车实施成本，而这使得现有“锂电车”产

品之车型过干单一化。比如，目前市面上锂电产品多为“电单车”而目续程不是很远的车型，但是像四轮电动车，

四轮老人电动代步车这些比较远续程的就目前情况还是比较适合铅酸电池”。总之铅酸电池和锂电池哪个好，不

能单纯的以电池的质量好坏而论，二者各具优劣，适应干不同的需求人群，消费者应根据自己需求选择。

Which is better for electric vehicle lithium battery or lead-acid battery

                                                        Advantages and disadvantages of lead-acid batteries

*High cost performance It is generally believed that lead-acid batteries for electric vehicles are better than lithium batteries, mainly because lead-acid batteries are safer, relatively cheap, and more acceptable to the public.

The most important thing is that the recycling price of lead-acid batteries is higher than that of lithium batteries.

*High-rate discharge performance is better. Generally speaking, a set of lead-acid batteries is only a few hundred pieces, and a set of lithium batteries is more than one thousand and nearly two thousand. lead

The acid battery has strong overload capacity and strong shock resistance. The resistance of the electric vehicle during driving changes at any time, or even stops suddenly. At this time, the battery current changes greatly.

In the few seconds of the ignition, the current reaches two or three hundred amps, and the lead-acid battery can be safe, while the lithium battery is unmatched.

* Lead-acid batteries also have shortcomings, such as heavy metals that are easy to cause environmental pollution; lead-acid batteries have lower energy density than lithium batteries; and their service life is not long

and lithium batteries.

                                                             Lithium battery advantages and disadvantages

*High energy efficiency Lithium batteries are more than 3 times higher than lead-acid batteries in terms of volume specific energy or weight specific energy. Lithium batteries are smaller, lighter, and have longer cycle life.

* Lightweight and environmentally friendly Lithium batteries are relatively lightweight, easy to carry, and have a relatively long life. In addition, the high and low temperature adaptability of lithium batteries is stronger, which is affected by temperature

The factor is smaller and more green.

*Lithium batteries also have three disadvantages: their safety and stability are relatively poor, and if they are improperly operated, they are prone to the risk of explosion. In addition, lithium batteries do not

The production requirements of high-current discharge items are high, and the cost is higher.

                                                                     summary

At present, the market penetration rate of lithium electric vehicles is low. The main factor of dry lead-acid battery vehicles is the imperfect technology, and the cost of lithium batteries is still relatively high. therefore

In the design of the existing "lithium electric car" products, the capacity configuration of the lithium battery is often reduced to correspondingly reduce the implementation cost of the whole vehicle, which makes the existing "lithium electric car" production

The model of the product is too dry and single. For example, most of the current lithium battery products on the market are "motorcycles" with a short range, but like four-wheeled electric vehicles,

Four-wheeled electric scooters for the elderly are more suitable for lead-acid batteries in the current situation.” In short, which is better, lead-acid batteries or lithium batteries, no

It can be purely based on the quality of the battery. Both have their own advantages and disadvantages. They are suitable for people with different needs. Consumers should choose according to their own needs.
