New All-Weather Battery Doubles Energy Density, Boosts EV Range

3/28/2026

Summary

Story summary

Batteries using an all-weather hydrofluorocarbon-based electrolyte developed by Shanghai and Tianjin teams have more than double the energy density of traditional lithium batteries at room temperature.
These batteries can operate efficiently at temperatures as low as minus 70 degrees Celsius.
Li Yong, the study author from Shanghai and Tianjin teams, noted the potential to increase electric vehicle ranges from 500–600 km to 1,000 km.
The findings were published in Nature.
