Abstract

In a method of characterizing a polymer binder for cell electrodes in contact with an electrolyte and including a current collector and a paste containing an electrochemically active material and said binder, a spreading coefficient of the binder on the active material is calculated from the measured angle of contact between standard liquids and the active material and the binder, respectively. An interaction energy of the binder with the electrolyte is calculated from the measured angle of contact between the electrolyte and the binder. The binder is selected such that the spreading coefficient is less than zero and the interaction energy is at least 60 mJ/m.sup.2.

Electronically conductive polymer binder for lithium-ion battery electrode

Patent Liu, Gao; Xun, Shidi; Battaglia, Vincent S.; ...

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

Transition metal hexacyanometallate electrode with water-soluble binder

Patent Wang, Long; Lu, Yuhao; Vail, Sean

A method is provided for fabricating a transition metal hexacyanometallate (TMHCM) electrode with a water-soluble binder. The method initially forms an electrode mix slurry comprising TMHCF and a water-soluble binder. The electrode mix slurry is applied to a current collector, and then dehydrated to form an electrode. The electrode mix slurry may additionally comprise a carbon additive such as carbon black, carbon fiber, carbon nanotubes, graphite, or graphene. The electrode is typically formed with TMHCM greater than 50%, by weight, as compared to a combined weight of the TMHCM, carbon additive, and binder. Also provided are a TMHCM electrode mademore »« less
