Tokyo Tech doubles voltage of safer aqueous proton battery

Cell recharges faster than lithium-ion and won't burst into flames

TOKYO -- A team from the Tokyo Institute of Technology has successfully tested an aqueous proton battery that doubles the voltage of previous prototypes, bringing the next-generation battery closer to commercial feasibility.

Aqueous proton batteries release electricity via the movement of hydrogen ions, also known as protons. They are seen as a possible alternative to lithium-ion batteries because they are not prone to catching fire.
