Lithium ion polymer secondary battery its electrode and method for synthesizing polymer compound in binder used in adhesion layer thereof

A lithium ion polymer secondary battery comprising:

• a positive electrode comprising a positive electrode current collector, and a positive electrode active material layer, which contains a first binder containing a polymer compound and a positive electrode active material, provided on the surface of the positive electrode current collector,
• a negative electrode comprising a negative electrode current collector, and a negative electrode active material layer which contains a second binder containing a polymer compound that is the same as or different from that of the first binder, and a negative electrode active material, provided on the surface of the negative electrode current collector, and
• an electrolyte,
• wherein a first bonding layer is interposed between the positive electrode current collector and the positive electrode active material layer, and a second bonding layer is interposed between the negative electrode current collector and the negative electrode active material layer,
• the first and second bonding layers contain both a third binder and a conductive material, and
• the third binder contains a polymer compound obtained by modifying either or both of the polymer compounds contained in the first and second binders or a polymer compound having any of repeating units of the polymer compounds, with modifying material.
