Abstract
The invention concerns a high temperature lithium-sulfur secondary battery, characterized in that the cathode pellet is made from titanium disulphide. An electrolyte pellet is preferably prepared from a mixture of alkali metal halides.
Claims18
In a high temperature lithium-sulphur secondary battery comprising a stack of cells, each cell including a pellet of electrolyte suitable for said secondary battery and sandwiched between a negative electrode pellet composed at least partially of lithium and a positive electrode pellet, and an intercell metal sheet adapted to prevent direct chemical action between the electrode pellets of adjacent cells while maintaining electrical contact between them,
- the improvement comprising using a positive electrode pellet composed substantially of titanium disulphide in combination with the components of said lithium-sulphur secondary battery.
A high temperature lithium-sulphur secondary battery comprising a stack of cells, each cell including a pellet of electrolyte composed of a mixture of alkali metal halides at least one of which is a lithium salt, said electrolyte sandwiched between a negative electrode pellet composed at least partially of lithium and a positive electrode pellet composed substantially of titanium di-sulphide, and an intercell metal sheet adapted to prevent direct chemical action between the electrode pellets of adjacent cells while maintaining electrical contact between them.
