COMPOSITE BINDER FOR BATTERY, ANODE AND LITHIUM BATTERY CONTAINING THE BINDER

摘要

PURPOSE: A battery complex binder is provided to improve the lifetime and cycle property of a lithium battery by accepting and/or suppressing the volume change of non-carbon system negative electrode active materials. CONSTITUTION: A battery complex binder comprises inorganic particles, binder polymers and organic and inorganic binders. The inorganic particles are dispersed within the binder polymers. The organic and inorganic binders are arranged in at least a portion of the inorganic particles. The inorganic particles are at least one selected from a group consisting of metal oxide and metalloid oxide. The organic and inorganic binders are silane compounds or silane coupling agents. A negative electrode includes negative electrode active materials and the complex binder for a battery.
