Negative electrode |
| abstract |
A non-aqueous electrolyte battery with improved safety is provided. The nonaqueous electrolyte battery includes a negative electrode, a positive electrode, and a nonaqueous electrolyte. The negative electrode includes negative electrode active material particles 10. The negative electrode active material particles 10 include spinel type lithium titanate 11. In the negative electrode, the ratio ALi / ATi between the Li atom abundance ratio ALi and the Ti atom abundance ratio ATi obtained by photoelectron spectroscopy on the surface is 0.002 or more per cycle in a charge / discharge cycle test in a 45 ° C. environment. It has a surface condition that increases at a rate of 0.02 or less. The Li atom abundance ratio ALi is calculated from a peak derived from the 1s orbital of Li appearing in the binding energy region of 52 eV to 58 eV. The Ti atom abundance ratio ATi is calculated from a peak derived from a 2p orbital of Ti that appears in a binding energy region of 455 eV to 462 eV. The negative electrode active material particles 10 have a lithium titanate layer 12 having a rock salt structure on at least a part of the surface. [Selection] Figure 1 |
