Active substance for negative electrode of lithium secondary battery, negative electrode of lithium secondary battery and lithium secondary battery |
| abstract |
A prolonged-life highly safe lithium secondary battery for which enhancement of high output/high input performance by reduction of the thickness of active substance layer can be realized. There is provided an active substance of carbonaceous powder for negative electrode of lithium secondary battery, wherein with respect to a dispersion obtained by dispersing 100g of active substance powder together with 2g of carboxymethylcellulose in 200g of water, the grain diameter at graining initiation as measured on the basis of dispersion degree according to the grind (fineness) gauge method defined in JIS K5400 is 50μm or less. There is further provided a negative electrode of lithium secondary battery, comprising a current collector and, superimposed thereon, an active substance layer containing an active substance and an organic material capable of exerting binding and thickening effects, wherein the active substance layer has a thickness of 50μm or less and an arithmetic average roughness (Ra), measured in accordance with JIS B0601, of 5μm or less. This active substance is a powdery active substance consisting of amorphous coated graphite The provided lithium secondary battery comprises this negative electrode. |
