Solid-state batteries have been gaining attention for their potential to offer longer range, faster charging, and improved safety. However, durability has been a major hurdle in their development. Researchers in China have made a significant breakthrough by developing a new solid-state battery electrolyte system that maintained over 84% of its capacity after 350 charge cycles. This achievement brings solid-state batteries one step closer to commercialization. The new electrolyte system has shown promising results, with a high capacity retention rate and improved stability. This development has significant implications for the battery industry, as it could enable the widespread adoption of solid-state batteries in electric vehicles and other applications. Electrek

CATL, a leading battery manufacturer, has launched a new sodium-ion battery product called Tener Sodium. This move marks a significant expansion of CATL's energy storage offerings and pushes sodium energy storage to the market. Sodium-ion batteries have been gaining attention as a potential alternative to lithium-ion batteries, offering improved safety, lower costs, and increased sustainability. CATL's Tener Sodium product is expected to play a key role in the development of sodium-ion battery technology and its adoption in various applications. CnEVPost

A recent study has found that an ex-rental Tesla's battery degradation slowed down after an initial decline. The Tesla, which was abused and lost 20% of its capacity in the first two years, appeared to have plateaued in terms of battery degradation. This finding has significant implications for the battery industry, as it suggests that battery degradation may not be a linear process and that batteries may be more resilient than previously thought. The study's results also highlight the importance of proper battery maintenance and care in minimizing degradation. InsideEVs
