High-capacity iron-based cathodes for EV batteries are now a reality

Researchers at Canada’s McGill University published a couple of studies that unlock the potential to produce batteries using more sustainable and less costly materials, known as disordered rock-salt-type (DRX) cathode materials.

In the first study, published in Advanced Energy Materials, the scientists explain how they successfully engineered iron-based DRX cathodes by modifying the electron storage process, achieving some of the highest storage capacity recorded for iron-based cathodes. The breakthrough could slash lithium-ion battery costs by 20%.
