Lithium-iron disulphide batteries. Electrolyte: molten salts
Electric batteries - Activatable batteries

Designed for thermal cell applications because of the high mass energies it can achieve, this pairing has also been studied for its low material cost, and has been developed for operation at ambient temperature. , for high-temperature operation in molten salt electrolyte thermal batteries (this article), but it has also been studied as an accumulator for application in electric vehicles (high-temperature accumulators).

In its application to thermal batteries, the aim was to gain an important factor in terms of energy by mass, compared with calcium-chromate batteries
