3-D Printed Batteries Handle the Squeeze

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 e...
