Implantable batteries can run on the body's own oxygen

From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and to dampen pain. But batteries eventually run low and require invasive surgeries to replace.

Air-stability of sodium-based layered-oxide cathode materials

Sodium ion batteries are considered to be one of the most promising alternative systems to lithium-ion batteries, especially for large scale applications. Sodium-based transition-metal oxides with layered structure have been ...

Batteries mimic mammal bones for stability

Sodium-ion batteries are poised to replace lithium-ion batteries for large-scale electrical energy storage. They offer several advantages over lithium-ion batteries, particularly due to the widespread abundance of sodium.

Method to predict the atomic structure of sodium-ion batteries

Researchers from the Chinese Academy of Sciences and Delft University of Technology (TU Delft) have developed a method to predict the atomic structure of sodium-ion batteries. Until now, this was impossible even with the ...
