Patent number: 10170765Abstract: A family of carboxylic acid groups containing fluorene/fluorenon copolymers is disclosed as binders of silicon particles in the fabrication of negative electrodes for use with lithium ion batteries. Triethyleneoxide side chains provide improved adhesion to materials such as, graphite, silicon, silicon alloy, tin, tin alloy. These binders enable the use of silicon as an electrode material as they significantly improve the cycle-ability of silicon by preventing electrode degradation over time. In particular, these polymers, which become conductive on first charge, bind to the silicon particles of the electrode, are flexible so as to better accommodate the expansion and contraction of the electrode during charge/discharge, and being conductive promote the flow battery current.Type: GrantFiled: September 24, 2015Date of Patent: January 1, 2019Assignee: The Regents of the University of CaliforniaInventors: Gao Liu, Vincent S. Battaglia, Sang-Jae Park

Patent number: 8703009Abstract: The present invention provides for a lithium ion battery and process for creating such, comprising higher binder to carbon conductor ratios than presently used in the industry. The battery is characterized by much lower interfacial resistances at the anode and cathode as a result of initially mixing a carbon conductor with a binder, then with the active material. Further improvements in cycleability can also be realized by first mixing the carbon conductor with the active material first and then adding the binder.Type: GrantFiled: November 6, 2009Date of Patent: April 22, 2014Assignee: The Regents of the University of CaliforniaInventors: Gao Liu, Vincent S.
