| description | The invention provides a method for testing the stability of an internal structure of a lithium battery during quick charging . The method comprises the following steps of measuring the large-currentcharging capacity of a lithium ion battery; carrying out rate charging circulation on the lithium ion battery; performing computed tomography test on the lithium ion battery to obtain battery internalelectrode section image information; and analyzing the computed tomography image information. The invention further comprises a method for evaluating stability of the internal structure of the lithium battery during quick charging. The method aims at the endurance capacity of the lithium battery to rapid charging and is based on the computed tomography technology, the internal structure stabilityof the lithium ion battery during rapid charging can be effectively tested, more accurate data support is provided for the process upgrading and evaluation technology development of the lithium battery. and evaluation indexes |
