Abstract
Official abstract text for this publication.
A sheet-form electrode for a secondary battery includes a current collector; an electrode active material layer formed on one surface of the current collector; a porous organic-inorganic layer formed on the electrode active material layer and including inorganic particles and a polymer binder; and a first porous supporting layer formed on the porous organic-inorganic layer. The sheet-form electrode for a secondary battery has supporting layers on at least one surface thereof to exhibit surprisingly improved flexibility and prevent the release of the electrode active material layer from a current collector even if intense external forces are applied to the electrode, thereby preventing the decrease of battery capacity and improving the cycle life characteristic of the battery.
First claim
Opening claim text (preview).
What is claimed is: 1. A secondary battery comprising a cathode, an anode, a separator interposed between the cathode and the anode, and a non-aqueous electrolyte solution, wherein at least one of the cathode and the anode is a sheet-form electrode for a secondary battery, comprising a current collector, an electrode active material layer formed on one surface of the current collector, a porous organic-inorganic layer formed on the electrode active material layer and comprising in…
