What Kind of Batteries Do New Energy Vehicles Use?

[NovaMarie]

New energy vehicles primarily use alkaline batteries, lithium-ion batteries, lithium iron phosphate batteries, and ternary lithium batteries. Alkaline Batteries: Alkaline batteries are composed of nickel-based materials and alkaline solution electrolytes. They mainly include three types: nickel-cadmium batteries, nickel-zinc batteries, and nickel-metal hydride batteries. Among these, nickel-metal hydride batteries have higher specific energy and are environmentally friendly compared to nickel-cadmium and nickel-zinc batteries. Lithium-ion Batteries: Lithium-ion batteries can be divided into two types: lithium-ion batteries and lithium polymer batteries. Lithium Iron Phosphate Batteries: Compared to traditional lead-acid battery packs, lithium iron phosphate batteries have advantages in terms of working voltage, energy density, and cycle life. However, their biggest drawback is the relatively shorter driving range. Ternary Lithium Batteries: Currently the most mainstream power battery packs. The cathode material of these battery packs is generally lithium cobalt oxide. Compared to lithium iron phosphate battery packs, ternary lithium batteries exhibit significantly better driving range performance.
