5+ day, 9+ hour ago   (235+ words) A new technology has been developed to overcome the limitations of next-generation batteries whose performance declines because silicon repeatedly expands and contracts during charge–discharge cycles. A battery using the new technology retained 94.2% of its initial capacity even after 300 charge…...

6+ day, 8+ hour ago   (346+ words) Seoul National University · LG Energy Solution Research results have been presented that increase the likelihood of actually applying next-generation battery materials that use inexpensive manganese instead of costly cobalt to large battery cells for electric vehicles. LMR is a next-generation…...

2+ week, 6+ day ago   (341+ words) A Korean research team has implemented the internal structure of a lithium-ion battery as a three-dimensional digital twin and identified ways to enhance the battery’s charging speed and performance. The results are expected to help quantitatively elucidate internal changes in…...

4+ week, 2+ day ago   (316+ words) High-capacity batteries exhibit a phenomenon known as “degradation,” in which performance drops rapidly as charging and discharging cycles are repeated. To use high-capacity batteries in electric vehicles and energy storage systems, this degradation must be mitigated. Previous studies focused on…...
