POSITIVE ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
A positive electrode active material for a nonaqueous electrolyte secondary battery contains, as a main component, a lithium composite oxide in which a ratio of Ni relative to a total number of moles of metal elements other than Li is greater than 30 mol %. The lithium composite oxide is a secondary particle being aggregation of primary particles having an average particle diameter of 3 μm or more and 20 μm or less, and having a compression rupture strength of 100 MPa or more and less than 200 MPa. The lithium composite oxide contains at least one element selected from Ba, Ca, and Sr. |
