Lithium battery alumina separator is a key material used in lithium-ion batteries. It significantly improves the safety and performance of lithium batteries by coating a thin layer of alumina on the traditional polymer-based membrane. The main function of the alumina separator is to separate the positive and negative electrodes of the battery, prevent internal short circuits, and allow lithium ions to migrate freely during charging and discharging. The addition of alumina coating gives the separator better thermal stability, mechanical strength and corrosion resistance to the electrolyte, especially in high temperature environments, it can effectively prevent the separator from melting or shrinking, thereby greatly improving the safety of the battery.
