The team, led by researchers from the Chinese Academy of Sciences, developed a self-healing interface that works like a liquid seal. It flows to fill tiny gaps, keeping the battery’s internal layers tightly joined without the heavy pressure and bulky devices previously needed to hold them together.
Chunsheng Wang, a solid-state battery expert at the University of Maryland, College Park who was not involved in the study, said it had “resolved the key bottleneck that has long hindered the commercialisation of all-solid-state batteries, marking a decisive step towards their practical application”.
While conventional designs require more than 5 megapascals – about 50 atmospheres – of external pressure to keep the internal layers stable, the Chinese team’s technology “fundamentally changed this predicament”, Wang told state-run Science and Technology Daily.
