Abstract
A lithium secondary cell includes a negative electrode, a positive electrode, and a non-aqueous lithium-containing electrolyte solution. The negative and/or positive electrode includes a current collector, an underlying layer, and an electrode layer. The underlying layer is formed of a thermoset composition comprising carbon black, a thermosetting fluorinated polymer, and a crosslinking agent or a radiation-cured composition comprising carbon black, a radiation-curable polymer, and optionally a radiation-curable compound. The underlying layer is effective for maintaining firm adhesion between the current collector and the electrode layer during repetitive charge/discharge cycles.
