Wireless charging is a game-changer in Arctic conditions, where swapping batteries in extreme cold is almost impossible, so the project is state-funded.

Russian Scientists Create World’s First Wirelessly Charged AA Battery
The device, designed by Russia’s Information Technologies, Mechanics and Optics University specialists, can charge via a standard Qi charging pad – just like your smartphone.
The battery looks like a standard AA, maintains 1.5V, and fits existing devices – no special hardware needed
Engineers curved the charging coil along the battery's wall instead of using a flat one, solving the space problem inside the cylindrical casing
A smart voltage converter gradually drops output as the charge depletes, giving devices a warning (flashing light) instead of a sudden shutdown
Wireless charging is a game-changer in Arctic conditions, where swapping batteries in extreme cold is almost impossible, so the project is state-funded.
