Partial energy storage

What makes a rechargeable battery a fast energy storage device?

Nature Energy 5, 213–221 (2020) Cite this article The rapid market growth of rechargeable batteries requires electrode materials that combine high power and energy and are made from earth-abundant elements. Here we show that combining a partial spinel-like cation order and substantial lithium excess enables both dense and fast energy storage.

Can a kinetically-advantageous partial-spinel-like cation order achieve a high energy density?

We have demonstrated that combining a kinetically-advantageous partial-spinel-like cation order with substantial Li excess and F substitution is effective for achieving both a high energy density and an excellent rate capability in Li-ion battery cathodes.

Can Li-ion cathode materials provide fast and dense energy storage?

Our discovery provides a model for the realization of both fast and dense energy storage in Li-ion cathode materials.
