What are the types of new energy batteries?

[Kathryn]

New energy electric vehicle batteries are classified as follows: Lead-acid batteries: Lead-acid batteries have low cost, good low-temperature performance, and high cost-effectiveness; but they have low energy density, short lifespan, large size, and poor safety. Due to their low energy density and short lifespan, electric vehicles powered by them cannot achieve good speed or high range, and are generally used in low-speed vehicles. Nickel-metal hydride batteries: Nickel-metal hydride batteries have low cost, mature technology, long lifespan, and durability; but they have low energy density, large size, low voltage, and suffer from memory effect. Although their performance is better than lead-acid batteries, they contain heavy metals, which can cause environmental pollution if discarded.
