What Are the Key Differences Between NiMH and Lithium-Ion Batteries?

How Do NiMH and Lithium-Ion Batteries Work?

NiMH batteries use a nickel-metal hydride anode and nickel oxide cathode, exchanging hydrogen ions for energy storage. Lithium-ion batteries rely on lithium ions moving between graphite anodes and metal oxide cathodes. NiMH operates …

What Are the Key Differences Between 3.6V and 3.7V Li-ion Battery Packs

Li-ion battery packs labeled 3.6V and 3.7V differ in nominal voltage, reflecting slight variations in electrochemical design. The 3.7V is common in consumer electronics, while 3.6V often serves industrial applications. Both operate within a 3.0V–4.2V range, but 3.7V packs prioritize …
