Negative electrode active material, method for producing the negative electrode active material, and lithium ion secondary battery using the negative electrode active material |
| abstract |
Disclosed is a negative electrode active material which has a high capacity and good cyclability. The negative electrode active material comprises nanosize carbon particles and nanosize tin dioxide particles that are supported in a high-dispersion state on the nanosize carbon particles. The negative electrode active material has a high discharge capacity because of the reversible progress of a conversion reaction of tin dioxide (SnO 2 +4Li + +4e - → 2Li 2 O+Sn) therein. In a charge-discharge cycle test within a voltage range of 0 to 2 V vs. an Li/Li + electrode, the negative electrode active material shows a discharge capacity retention rate of about 90% even after 500 charge-discharge cycles at the rate 1C, which indicates excellent cyclability. Therefore, the negative electrode active material can be suitably used in a lithium ion secondary battery and a hybrid capacitor. |
