Stable high energy density materials for lithium-ion batteries
A method that uses ionic liquid electrolytes in combination with transition metal fluorides to achieve lithium-ion batteries with stable cycling and a high energy density.
Transition metal fluorides are unique materials that exhibit high energy densities. Oxford researchers have developed a method that exploits their properties to develop stable lithium-ion batteries with a high energy density.
Applications: Lithium-ion batteries, fluoride-ion batteries
