A review article in eTransportation discusses the challenges and solutions for fast charging of lithium-ion batteries. These batteries power most portable electronics, electric vehicles, and energy storage systems. Researchers are working to improve their performance. The review examines the physical phenomena limiting charging speeds, degradation mechanisms from high current charging, and proposed solutions. The study was conducted by Anna Tomaszewska and colleagues at Imperial College, London, along with co-authors in China and the U.S. Two main issues hindering electric vehicle adoption are range limitations and long charging times. High currents reduce efficiency and accelerate battery degradation. The authors evaluate various approaches, focusing on challenges from low-temperature charging. They identify knowledge gaps and recommend future research directions. Key requirements include reliable degradation detection methods and temperature control to prevent overheating and preheat in cold weather. Other innovations may come from more robust electrode materials and advanced charging current control methods. Electrification of vehicles and other applications is a promising way to combat climate change, but further research and technological advances are needed.
