A new generation of battery developed by scientists at Oregon State University shows promise for sustainable, high-power energy storage.
This may provide a paradigm-shifting opportunity for more sustainable batteries. said Xiulei Ji, assistant professor of chemistry at OSU and the corresponding author on the research.It doesn’t use lithium or sodium or potassium to carry the charge, and just uses acid as the electrolyte. There’s a huge natural abundance of acid so it’s highly renewable and sustainable.
No nonmetal cations were being considered seriously for batteries, he said.
Organic solids are not typically contemplated as crystalline electrode materials, but many are very crystalline, arranged in a very ordered structure, Ji said. This PTCDA material has a lot of internal space between its molecule constituents so it provides an opportunity for storing big ions and good capacity.
It’s not going to power electric cars, Ji said. But it does provide an opportunity for battery researchers to go in a new direction as they look for new alternatives for energy storage, particularly for stationary grid storage.
