++ 2H
2O.Moreover, owing to contain Mn3+ in the spinelle, under acid condition disproportionated reaction: 2Mn can take place
3+→ Mn
4++ Mn
2+, Mn
2+Then be dissolvable in water in the electrolyte, thereby cause the minimizing of active material, and under hot conditions, disproportionated reaction speed is faster.The capacity attenuation of LiMn2O4 makes it be used for large-scale lithium ion battery and is subjected to certain obstruction.
