Episode 537 - Better batteries that last even in subzero temperatures

Batteries power the modern world, but how can we make them more sustainably and last longer. Lithium powers most of our modern batteries but it doesn't cope with the cold. The electrolytes inside lithium ion batteries are powerful but weak when its cold, so what can we use instead? Extracting lithium is carbon intensive and difficult, are there more abundant materials we can use? Calcium based batteries have a higher power density than lithium but finding a suitable electrolyte is a challenge. Kazuaki Kisu, Rana Mohtadi, Shin‐ichi Orimo.
