NONAQUEOUS ELECTROLYTE SECONDARY BATTERY ELECTRODE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce the unevenness in the distribution of an electrolyte in an electrode mixture material layer.SOLUTION: A nonaqueous electrolyte secondary battery electrode comprises: an electrode mixture material layer. The electrode mixture material layer includes: hollow active material particles 2; and a needle-like filler 4 having therein a communicating hole 4a extending in a longitudinal direction. The needle-like filler 4 is disposed on the surface of the hollow active material particle 2.SELECTED DRAWING: Figure 2
