There are about three types of electric vehicle batteries on the market. The first is lead-acid batteries. This kind of battery is very easy to distinguish, because it is thick, but the capacity and battery life are average, the life is very short, and the only advantage is that it is cheap.

　　The second type of battery is a lithium iron battery. This is the true king of battery life, but there are not many manufacturers who master this battery technology, and the raw materials are high. This battery is very expensive.

　　The third type of battery is ordinary colloidal lithium battery. Lithium batteries can not only be charged or used at any power without affecting their life, but are also small in size, high in capacity, and long in battery life, so they are the standard for many electric vehicles.

　　Due to the relatively short lifespan of lead-acid batteries, the battery life of electric vehicles equipped with such batteries tends to drop rapidly and drastically.

　　So now many manufacturers are beginning to use colloidal batteries as battery applications for electric vehicles.
