Lithium ion secondary battery |
| abstract |
A lithium ion secondary battery 100 A has negative electrode active material particles 710 A which include graphite particles that are at least partially covered by an amorphous carbon film 750 . The negative electrode, active material particles 710 A have a TG weight-loss-on-heating onset temperature T1 which satisfies the condition 500° C.≦T1≦615° C. and a micro-Raman G-band half-width Gh which satisfies the condition 20≦Gh≦28. This configuration makes it possible to obtain a lithium ion secondary battery 100 A in which the reaction resistance in a low-temperature environment can be kept low. |
