Stable high energy density materials for lithium-ion batteries

Applications: Lithium-ion batteries, fluoride-ion batteries

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.

Features	Benefits
The battery uses ionic liquid electrolytes to enable the cycling of transition metal fluorides.	Achieves stable cycling and high performance. High practical charge/discharge rates.
Can achieve the full theoretical capacity of transition metal fluorides with minimal capacity loss over time.	Transition metal fluorides allow battery capacities three to five times greater than conventional lithium-ion batteries.
Materials have little to no flammability and cycling stability is uncompromised at higher temperatures.	Safer battery system than those based on conventional organic electrolytes. The battery can withstand power surges.
Avoids complex fabrication methods normally associated with transition metal fluorides.	Batteries are easy to manufacture.
