KATHMANDU: The Chinese Academy of Sciences (CAS) has announced a major breakthrough in solid-state lithium battery research. The new battery uses polymer molecules to create a flexible structure with stable power output and high energy density.
The research was done by the Institute of Metal Research under CAS and published in the journal Advanced Materials. According to the team, regular solid-state batteries have weak contact between the electrode and electrolyte, which reduces their performance.
To fix this problem, the new design uses polymer molecules, ethoxy groups, and short sulfur chains. These materials help ions move more easily and store more energy. With this setup, the battery’s energy density increased by up to 86%.
The flexible battery was very durable and could bend 20,000 times without damage. However, CAS said it is still under research and not ready for large-scale production yet.
Solid-state batteries are seen as the next big step in EVs, as they offer higher capacity and better safety. Several Chinese companies, including Farasis Energy and Chery-backed Anhui Anwa, have already started pilot projects in this field.
