摘要:
A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.
摘要:
Disclosed is a binder for electrode formation, which is improved in corrosion resistance to electrolyte solutions, binding properties, stability and internal resistance, and thus enables to achieve excellent cycle characteristics when used in a battery and excellent heat degradation resistance when used in a capacitor. Specifically disclosed is a binder for electrode formation, which is obtained by dispersing a polyolefin resin containing 50-98% by mass of an unsaturated hydrocarbon having 3-6 carbon atoms and 0.5-20% by mass of an unsaturated carboxylic acid unit in an aqueous medium together with a basic compound. This binder for electrode formation is also characterized in that the content of a non-volatile aid for making a resin aqueous is not more than 5 parts by mass per 100 parts by mass of the polyolefin resin.
