The lithium-ion battery comprises a negative electrode (14) , a positive electrode (10), and an electrolyte (12) containing a molten salt, a lithium salt, and an electrolyte additive. The electrolyte additive is chosen to increase the lithium ion conductivity of the electrolyte. The electrolyte additive may be an organic additive, such as an organic carbonate. Ia other examples, the electrolyte additive provides a source of alkali metal cations other than lithium, such as potassium, sodium, and/or cesium ions. An analogous approach can be taken for batteries using ionic species other than lithium. |
