👉 The charger fluid, also known as Li-ion battery electrolyte, is a crucial component in lithium-ion batteries, including those used in electric vehicles and portable electronics. It's a specially formulated liquid mixture that facilitates the transfer of ions between the positive cathode and negative anode during charging and discharging processes. This fluid typically consists of lithium salts dissolved in organic solvents, ensuring efficient ion mobility and preventing the formation of dendrites that could cause short circuits or reduce battery lifespan. The charger fluid also helps maintain the battery's structural integrity and ensures safe operation by preventing overheating and leakage.
