What are the types of power batteries?

[VonOlivia]

The types of power batteries are mainly divided into: lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries, and sodium-sulfur batteries. Lithium-ion power batteries have the following advantages: high working voltage, high specific energy, small size, light weight, long cycle life, low self-discharge rate, no memory effect, and no pollution. Fuel cells are devices that directly convert chemical energy into electrical energy, with the positive electrode being an oxygen electrode and the negative electrode being a fuel electrode such as hydrogen, hydrocarbons, or ethanol. Nickel-metal hydride batteries can undergo rapid charge and discharge processes. When a car is driving at high speed, the electricity generated by the generator can be stored in the onboard nickel-metal hydride battery. When the car is driving at low speed, it typically consumes more gasoline than when driving at high speed. Lead-acid batteries are widely used as the power source for starting internal combustion engine vehicles. Sodium-sulfur batteries can release three times their inherent energy instantaneously and have high charge and discharge efficiency.
