PROBLEM TO BE SOLVED: To provide an electrode structural body with a long cycle life, large capacity and high energy density, contributing to a secondary battery. SOLUTION: This electrode structural body has a plate-like collector 100, and an electrode-material layer 102 containing 35 wt.% or more main material composed of grains 101 having a mean grain size of 0.5 to 60 μm on one surface or both surfaces of the collector 101. Thereby, an electrode structural body is provided capable of solving the problem of a negative electrode being pulverized by repeated charging/discharging and suppressing internal short-circuiting caused by growth of deposited dendrite of lithium metal or zinc metal generated at the time of charging and causing performance deterioration. Hence, a secondary battery utilizing an oxidation-reduction reaction of lithium ions can be obtained, long having a cycle life, large capacity, and high energy density. |
