Lithium permanganate is an inorganic compound with the chemical formula LiMnO₄. It can be produced by the reaction of lithium sulfate and barium permanganate, and the trihydrate LiMnO₄·3H₂O can be crystallized from the solution. It decomposes violently at 199 °C:^[2]

2 LiMnO₄ → Li₂O + 2MnO₂ + ³/₂ O₂↑

However, later research found that the thermal decomposition products of lithium permanganate are more complex, with products such as Li₂MnO₃ and LiMn₂O₄ being generated.^[3]
