NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18267249 titled 'NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
Simplified Explanation
The abstract describes a negative electrode for a nonaqueous electrolyte secondary battery, consisting of a negative electrode core and a negative electrode mixture layer on its surface. The mixture layer includes a first layer with metal elements (Si, Sn, Sb, Mg, Ge) and a compound containing them, carbon nanotubes, and a binding agent. It also has a second layer with graphite A having a specific particle fracture strength. The porosity of the first layer is 50-65%.

Original Abstract Submitted
A negative electrode for a nonaqueous electrolyte secondary battery, according to one embodiment of the present invention, is provided with a negative electrode core and a negative electrode mixture layer provided on the surface of the negative electrode core. The negative electrode mixture layer has a first layer that includes: at least one of at least one kind of metal element selected from Si, Sn, Sb, Mg, and Ge, and a compound containing said metal element; at least one of multi-walled carbon nanotubes and single-walled carbon nanotubes; and a binding agent. The negative electrode mixture layer also has a second layer that includes graphite A with a particle fracture strength of 10-35 MPa. The porosity of the first layer is preferably 50-65%.
