The 21C Innovation Lab team at CATL has unveiled groundbreaking research on lithium metal batteries in the esteemed journal 'Nature Nanotechnology'. This study delves into the underlying failure mechanisms of batteries and introduces innovative design principles for electrolytes, culminating in batteries with unprecedented energy density and extended cycle life. The research uncovered that electrolyte salt consumption was significantly higher than anticipated. By fine-tuning the formula, the team managed to double the cycle life to 483 cycles, with the potential to surpass 500Wh/kg in energy density in future iterations. This monumental advancement is poised to catalyze the evolution of electric aviation and long-range electric vehicles. Furthermore, the team's proprietary dynamic tracking technology offers a fresh lens through which to view lithium battery research.
