发明名称 LAMINATED BATTERY CELL AND METHODS FOR CREATING THE SAME
摘要 Electrodes with a multilayer or monolayer composite separator are described. The multilayer composite separator comprises multiple individual composite separator layers. Each individual composite separator layer comprises inorganic particulate material(s) and organic polymer(s) with different inorganic particulate material/polymer weight ratios. The multilayer composite separator layer is constructed in a way such that the composite separator layer adjacent to the electrode active material contains a higher weight percentage of the inorganic particulate material and lower weight percentage of the organic polymer than the composite separator layer outermost from the electrode current collector. Laminated cells comprising a positive electrode, a negative electrode, a laminated multilayer or monolayer composite separator layer are described, wherein at least one of the electrodes has a multilayer or monolayer composite separator disposed onto the surface of the electrode. Methods of making such laminated cells are also described.
