which is the best battery type?

1. Lithium-ion battery.

The specific capacity is better than NiMH battery, for the same capacity of lead-acid battery, the weight of lithium-ion battery is equivalent to a laptop computer, more charge and discharge cycles, high rated voltage, high temperature applicability, green and environmental protection, etc.. But the safety is not so good, there is the possibility of explosion and combustion, which is a problem that needs to be solved with lithium-ion batteries.

2. Lead-acid battery.

Cheap, low maintenance cost, pure manufacturing process, stable performance, good applicability, high recycling rate, China is the world's largest producer of lead-acid batteries. It contains less polluting components and has good recyclability, but the disadvantage is that the specific capacity is small. In other words, with the same capacity, the weight and volume of the battery are large, and the durability is relatively poor. Colloidal battery belongs to a development classification of lead-acid battery, the simplest practice, is to add gelling agent to sulfuric acid, so that the sulfuric acid electrolyte becomes colloidal.

3. Lead-acid batteries.

Lithium-ion batteries, nickel-hydrogen batteries, but now a large number of electric vehicles into the field or closed lead-acid gel battery, lithium batteries are also due to its small size, long life and flexible charging methods are also favored by the majority of users, but the high price of many customers to stay away.

4. NiMH battery.

High energy density, good low temperature performance, single cell life is also better, strong overcharge resistance, safe and pollution-free, etc. Its high current charge and discharge characteristics are also better than lead-acid batteries. The problem is that the management of NiMH batteries in series is more problematic, and once overcharging occurs, the poor resistance to high temperature will form the problem of melting of the single battery compartment, resulting in the rapid failure of the whole battery. The overall price is higher than that of lead-acid batteries and lithium batteries, but the overall performance is worse than that of lithium-ion batteries.

5. Zinc-air batteries.

Zinc air battery is a kind of metal-air battery, belongs to the category of semi-fuel cells. It has the advantages of high specific energy, abundant raw materials, low price, no pollution, etc., and is considered a competitive candidate for batteries for electric vehicles.

From the perspective of safety, lead-acid batteries are better than lithium batteries.

In terms of energy density, lithium batteries are better than lead-acid batteries.

In terms of service life, lithium batteries are better than lead-acid batteries.

From the price point of view, the price of lithium battery is higher than that of lead-acid battery.
