AMPERE LAB · Energy Storage Materials Lab
Materials that hold charge longer
We design cathodes and solid electrolytes for lithium and sodium batteries — and ways to catch a fire before it starts.
CELL LAYERSInside the cell
CATHODE
Cathode
Metal oxide that stores Li or Na ions — our main stage.

Elements we work with
It starts with the elements
- 3LiLithiumThe ion that shuttles between electrodes
- 28NiNickelMore nickel, more capacity — and more cracks
- 25MnManganeseKeeps the cathode lattice stable
- 8OOxygenReleased at high heat, it feeds fires
- 11NaSodiumCheap ion found even in seawater
- 26FeIronAbundant metal replacing cobalt
- 6CCarbonHard carbon that hosts sodium
- 16SSulfurSulfide electrolytes with fast ion flow
- 15PPhosphorusBackbone of the solid electrolyte
