Professor Xiulei 'David' Ji and his team at Oregon State University developed a new iron-based cathode for lithium-ion batteries.

This innovation offers higher energy density, lower costs, and greater safety compared to current cobalt and nickel cathodes.

Adding bromide to the electrolyte solution doubles the battery's energy capacity without compromising safety.

The research was funded by the U.S. Department of Energy and conducted in collaboration with other institutions.

The new iron-based cathode highlights the potential for iron to be a more sustainable and readily available option for battery production.

This advancement could revolutionize the battery industry and provide a more environmentally friendly solution for electric vehicles and electronic devices.
