Researchers are Developing Fast-Charging Solid-State Batteries

It’s All in the Mix

21-Aug-2018

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have ...

Salt is key ingredient for cheaper and more efficient batteries

11-Jul-2018

A new design of rechargeable battery, created using salt, could lead the way for greener energy. Researchers at the University of Nottingham Ningbo China (UNNC) have joined forces with a specialist group at the Shanghai Institute of Applied Physics (SINAP), Chinese Academy of Sciences on designs ...
