Chinese scientists have announced two major breakthroughs in solid-state lithium battery technology and resolved longstanding bottlenecks that have hindered commercial adoption of this potentially game-changing technology for the new energy vehicle sector.
The move comes as China tightened its export controls on lithium batteries and synthetic graphite materials, underscoring the nation’s strategic efforts in the global electric vehicle supply chain.
Researchers at the Institute of Metal Research under the Chinese Academy of Sciences said they have developed a new material that significantly reduces interfacial resistance and improves ion transport efficiency in solid-state batteries — two key challenges that have limited their practicality.
The team said that flexible batteries made from the new material maintained excellent bending endurance, surviving over 20,000 folding cycles. When used as a polymer…
