Description
Chuan Li and coauthors build a water based battery that still works at deep cold in 2026. Dual ion designs store charge in graphite at high voltage, yet they once needed costly, thick salt mixes that fail when cold. A gel rich in polar molecules replaces the thick mix here.
The gel holds only dilute salts yet stays stable past a wide voltage span at minus 40 degrees. High voltage scans wake the graphite to take in the charge carrying ions. Cells gave high plateaus at minus 20 and minus 40 degrees. Cold stores and polar sites gain a safer battery option.
