| 摘要 |
The present invention provides improved cathode compositions, improved cathodes, methods of producing improved cathodes including the cathode compositions and improved lithium secondary batteries. The cathode compositions of the invention are characterized by a particulate cathode active material, a particulate conductive substance and a binder formed of small fibers that are substantially homogeneously dispersed throughout the cathode composition but which do not encapsulate to any meaningful degree the particulate conductive substance and cathode active materials, so that a lithium secondary battery including the cathode composition has an improved charge-discharge rate capability and improved power and energy densities. |
