Lithium chlorate is the inorganic chemical compound with the formula LiClO3.

Like all chlorates, it is an oxidizer and may become unstable and possibly explosive if mixed with organic materials, reactive metal powders, or sulfur.

Its electrochemical reduction is facilitated by acid, electrocatalysts and redox mediators.

These properties make lithium chlorate a useful oxidant for high energy density flow batteries.

[5] Lithium chlorate has a very low melting point for an inorganic ionic salt.
