Abstract

Provided is a battery which has less tendency to experience delamination or loss of short circuit prevention layer and/or active material layer during manufacture and use. A battery comprising a laminated electrode assembly in which a positive electrode, a negative electrode, and a separator are laminated together; wherein an alumina-containing layer containing γ-alumina particles is formed on at least one species selected from among the group consisting of the positive electrode, the negative electrode, and the separator. The fact that alumina-containing layer(s) is or are made to contain γ-alumina particles makes it possible to obtain high bond strength between alumina-containing layer(s) and electrode(s) comprising metal(s), current collector(s) and/or active material(s) making up electrode(s), and/or separator(s). <img class="EMIRef" id="80434585-iaf01" />
