Document Type and Number:

Japanese Patent JP5818150

Kind Code:

B2

Abstract:

PROBLEM: To provide an electricity-storing device and an electrode for an electricity-storing device which, during manufacture and use, have less tendency to experience delamination or loss at active material layer(s) and/or layer(s) provided for short circuit prevention or serving other function(s). SOLUTION MEANS: Electricity-storing device electrode 10 comprises current collector foil 11; active material layer 12 formed on at least one surface of current collector foil 11; and high-resistance layer 40 formed on surface(s) of current collector foil 11 so as to be adjacent to and in direct contact with active material layer 12; wherein, at at least a portion of interface 50 between active material layer 12 and high-resistance layer 40, mixed phase 51 is formed where constituents from the two layers 12, 40 intermingle. By causing mixed phase 51 to be present at interface 50 between active material layer 12 and high-resistance layer 40, the bond between the two adjacent layers 12, 40 is made strong.
