👉 Battery fluid, also known as electrolyte solution, is a crucial component in many rechargeable batteries, including lithium-ion and nickel-metal hydride types. This fluid is typically a mixture of salts dissolved in an organic solvent, serving to facilitate the movement of ions between the battery's positive and negative electrodes during charging and discharging processes. It ensures that electrons can flow freely from the anode to the cathode while ions migrate through the electrolyte, maintaining electrical neutrality and enabling efficient energy storage and release. The fluid's properties, such as conductivity, viscosity, and stability, are carefully engineered to optimize battery performance, longevity, and safety.
