Separator for Lithium Batteries and Lithium Batteries Including the Separator.
Abstract
One of the primary problems that has limited development of rechargeable batteries has been the formation of dendrite lithium on the negative electrode. The general object of this invention is to provide a separator between the cathode and anode in lithium secondary or primary batteries that will eliminate internal shorting. A more specific object is to provide a separator material that will react with any lithium dendrite that could penetrate the separator thus preventing an internal short circuit of the battery. Polymers that can be electrodeposited, such as poly-3 methylthiophene can be used by first sputtering a thin layer of polymer can be electrodeposited on the metallized surface. Patent applications.
