Brief Battery Mechanism

Battery convert the chemical energy into electrical energy through redox reaction between active materials. Lithium-ion battery is considered as a prominent energy storage due to its high energy density compared to the other secondary-battery. The main components of lithium ion battery consist of Cathode, Anode, separator and electrolyte. During the charging event, Li-ion move from cathode and intercalate into the anode while the opposite phenomena occurs during discharge. The battery capacity is defined by the cathode-anode coupling. The LFP, LCO, NMC are the most used active material for cathode while carbon is the readily commercialized carbon.
