Battery Guide
Electric Car Power Battery Category
Classification by Electrochemical System
Lead-Acid Battery (Pb-Acid)
Low cost, good low-temperature performance, but low energy density, mostly used in microcars or auxiliary power supplies.
Nickel-Metal Hydride Battery (Ni-MH)
The mainstay of Toyota's early hybrid vehicles, with good over-discharge resistance, but average energy density and rate capability.
Lithium Iron Phosphate Battery (LFP)
High safety, cycle life of over 2,000 cycles, lowest cost, slightly weaker low-temperature performance.
Ternary Lithium Battery (NCM/NCA)
Highest energy density, long range, but high cost and thermal management requirements.
Lithium Cobalt Oxide/Lithium Manganese Oxide
Used in small quantities in specific vehicle models or low-speed vehicles.
Frontier Systems – Solid-State Lithium, Sodium-Ion, Lithium-Sulfur, etc.
