Enhancing Lithium-Ion Battery Charging Performance at Low Temperatures

Background Introduction Lithium-ion batteries (LIBs) have garnered significant attention regarding their performance at low temperatures, as their cycling performance declines sharply with decreasing temperature. Despite significant improvements in battery discharge capabilities in recent years, reversible charging of batteries at temperatures as low as -20°C or even lower remains challenging. The primary reason is the severe … Read more
