While flexible and stretchable electronics technologies have progressed in leaps and bounds over the past 10 years, batteries to power them have some catching up to do.
Researchers in Singapore and China have now demonstrated a “quasi-solid-state” battery—made from materials somewhere between a liquid and a solid—that can be compressed by as much as 60% while maintaining high energy density and good stability over 10,000 charge–recharge cycles.
The battery fabrication exploits 3-D printing, which, while attracting interest for producing complex battery structures, has posed challenges for batteries that can stretch, squash and bend while powering devices. “3-D printing technology is a very rapidly developing area,” says Hui Ying Yang , a materials science researcher at Singapore University of Technology and Design who led the research reported in ACS Nano . She explains that this prompted her and her […]
