Abstract
Official abstract text for this publication.
A battery includes a positive electrode, a negative electrode, a positive electrode lead which is connected to the positive electrode, and a protective tape which covers the positive electrode lead. The protective tape includes a base material layer and an adhesive layer that is arranged on the base material layer; and the adhesive layer contains an adhesive material and a filler which contains at least one compound that is selected from among phosphoric acid group-containing compounds, boric acid group-containing compounds and silicic acid group-containing compounds.
First claim
Opening claim text (preview).
