Lithium mixed metal oxide and nonaqueous electrolyte secondary battery |
摘要 |
A lithium mixed metal oxide comprising Ni, Mn and Fe and having a BET specific surface area of 2 m2/g or more and 30 m2/g or less. A method of producing a lithium mixed metal oxide, comprising bringing an aqueous solution containing Ni, Mn, Fe and Cl into contact with an alkali to obtain a coprecipitate, and calcining a mixture of the coprecipitate and a lithium compound by maintaining the mixture at a temperature of lower than 900° C. A positive electrode active material for nonaqueous electrolyte secondary battery, comprising the lithium mixed metal oxide described above or the lithium mixed metal oxide obtained by the method of producing a lithium mixed metal oxide described above as a main ingredient. A positive electrode for nonaqueous electrolyte secondary battery having the positive electrode active material for nonaqueous electrolyte secondary battery described above. |
