NiMH Vs Lithium: What’s The Difference?
NiMH (Nickel-Metal Hydride) and Lithium-ion (Li-ion) batteries differ fundamentally in chemistry, performance, and applications. NiMH uses nickel oxide hydroxide and hydrogen-absorbing alloys, offering moderate energy density (60–120 Wh/kg) and tolerance to overcharging. Lithium-ion batteries employ lithium compounds (e.g., LiFePO4, NMC) with higher energy density (150–250 Wh/kg), lower self-discharge, and no memory effect. While NiMH suits … Read more
