Li-ion/Na-ion Batteries & Battery Thermal Management System
July 12, 2022
Lithium-ion batteries are rechargeable batteries known for their high energy density, long lifespan, and versatility. They use lithium ions moving between an anode and cathode during charging and discharging. They are widely used in consumer electronics, electric vehicles, and energy storage applications due to their performance and adaptability. Sodium-ion batteries use sodium ions for energy storage instead of lithium ions. They are being developed as a more cost-effective alternative to lithium-ion batteries due to the abundance and lower cost of sodium. Battery Thermal Management Systems (BTMS) regulate battery temperature to optimize performance, prevent overheating, and ensure safety. They use cooling or heating systems, sensors, and controllers to maintain the ideal temperature range, crucial for battery lifespan and efficiency.
