Title:
リチウムイオン再充電可能電池セル
Document Type and Number:
Japanese Patent JP2012527069
Kind Code:
A
Abstract:
An electrode for a rechargeable battery cell includes a substrate, e.g., a current collector and a particulate silicon forming active material in the electrode, along with a cellulose based binder. At least one chelating agent is provided, the chelating agent being capable of binding to the metallic impurities, e.g., divalent and/or trivalent impurities. The binder is mixed with the silicon particles to form a cohesive mass that adheres to the substrate. It has been found that cellulose based binders can also be used in cells where the active material is silicon if a chelating agent is also incorporated. The electrode can be used in a lithium ion rechargeable battery cell.
