Method of preparing electrodes with porous current collector structures and solid reactants for secondary electrochemical cells

Patent Gay, Eddie C [Park Forest, IL]; Martino, Fredric J [Riverdale, IL]

Particulate electrode reactants, for instance transition metal sulfides for the positive electrodes and lithium alloys for the negative electrodes, are vibratorily compacted into porous, electrically conductive structures. Structures of high porosity support sufficient reactant material to provide high cell capacity per unit weight while serving as an electrical current collector to improve the utilization of reactant materials. Pore sizes of the structure and particle sizes of the reactant material are selected to permit uniform vibratory loading of the substrate without settling of the reactant material during cycling.

Current collector clad with lithium ion conducting solid electrolyte

Patent Sakamoto, Jeffrey; Thompson, Travis; Taylor, Nathan

An article for forming an electrochemical device is disclosed. The article comprises a metallic current collector clad with an ion conducting solid-electrolyte material such that intimate contact between the current collector and the ion conducting solid-electrolyte material is made. A lithium metal anode can be formed in situ between the current collector clad and the ion conducting solid-electrolyte material from lithium ions contained within a cathode material that is placed in contact with the ion conducting solid-electrolyte material. A bipolar electrochemical cell can be constructed from the article.

Electronically conductive polymer binder for lithium-ion battery electrode

Patent Liu, Gao; Battaglia, Vincent S.; Park, Sang-Jae

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 ofmore » « less
