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{{Cite journal |date=May 2006 |title=Zhurnal Neorganicheskoi Khimii (Inorganic Chemistry) is 50 |url=http://dx.doi.org/10.1134/s0036023606050287 |journal=Russian Journal of Inorganic Chemistry |volume=51 |issue=5 |pages=844–845 |doi=10.1134/s0036023606050287 |s2cid=189775040 |issn=0036-0236|url-access=subscription }} to a mixture of spinel salts:{{cite journal|journal=Journal of Solid State Electrochemistry|volume=16|issue=5|language=en|issn=1432-8488|date=May 2012|pages=1993–1998|doi=10.1007/s10008-011-1603-5|url=http://link.springer.com/10.1007/s10008-011-1603-5|title=Formation of spinel structured compounds in the lithium permanganate thermal decomposition|accessdate=2020-06-21|author=Alexander A.
