Abstract
Provided is a novel spinel-type lithium-manganese composite oxide, allowing gas generation amount to be limited for a gas generated via a reaction with an electrolytic solution. Proposed is a spinel-type lithium-manganese composite oxide, wherein, when the spinel-type lithium-manganese composite oxide is placed in an ion-exchanged water at 20° C., stirred for 10 minutes, then, left to stand undisturbed for 2 minutes, separated into a supernatant and a precipitate and recovered, with respect to the '-site-to--site inter-atomic distance (100%)' of the spinel-type lithium-manganese composite oxide contained in the precipitate measured by the Rietveld method using the fundamental method, proportionally, the '-site-to--site inter-atomic distance' of the spinel-type lithium-manganese composite oxide contained in the supernatant is less than 101.5%.
