Solid-state batteries have gained much traction over the past few years among researchers looking for alternatives. While conventional lithium-ion batteries contain a liquid electrolyte in which lithium ions flow during the charge and discharge process, solid-state batteries are made entirely from solid materials. Besides a massive improvement in operational safety, solid-state batteries can be changed much more quickly. But these batteries have been plagued by stability issues that impact their longevity.
Now, a team of researchers led by Professor Naoaki Yabuuchi of Yokohama National University, Japan, has investigated a new type of positive electrode material with unprecedented stability in solid-state batteries.
The material is made up of lithium titanate and lithium vanadium dioxide, ball-milled down to an appropriate particle size in the order of nanometers. This material…
