What are the five types of lithium batteries used in new energy vehicles?

[AllieDella]

New energy vehicles adopt the following five types of lithium batteries: Lead-acid battery: As a relatively mature technology, lead-acid batteries remain the only mass-produced batteries for electric vehicles due to their lower cost and high-rate discharge capability. Nickel-cadmium and nickel-metal hydride batteries: Although they perform better than lead-acid batteries, they contain heavy metals and can cause environmental pollution when discarded after use. Lithium-ion battery: Features include high working voltage, large specific energy (three times that of nickel-metal hydride batteries), compact size, lightweight, long cycle life, low self-discharge rate, no memory effect, and pollution-free. Lithium iron phosphate battery: Lithium iron phosphate batteries are also a type of lithium-ion battery. Although their specific energy is less than half that of lithium cobalt oxide batteries, they offer high safety, up to 2000 cycles, stable discharge, and low cost, making them a new choice for vehicle power. Fuel cell: Simply put, a fuel cell is a power generation device that directly converts the chemical energy present in fuel and oxidants into electrical energy.
