Electric vehicle (EV) batteries consist of an EV, storing and supplying the energy needed to power the electric motor. Unlike traditional internal combustion engines that rely on fuel, EVs use rechargeable batteries to achieve propulsion. Lithium-ion (Li-ion) batteries are the most widely used in modern EVs due to their high energy density, long cycle life, and lightweight properties. NiMH batteries are commonly used in hybrid electric vehicles (HEVs) due to their durability and safety. They have lower energy density and are more expensive compared to Li-ion batteries. Solid-state batteries use a solid electrolyte instead of a liquid one, offering improved safety and higher energy density. Lithium Iron Phosphate (LFP) Batteries are a subtype of Li-ion batteries, offering better thermal stability and safety at the cost of slightly lower energy density.
