Appl. No.:

12/614195

Inventors:

Gao Liu - Oakland CA, US
Vincent S. Battaglia - San Anselmo CA, US

International Classification:

H01M 2/00
H01M 4/58
H01M 4/04
H01M 10/04
B05D 5/12

US Classification:

429163, 42923195, 427 58, 296231

Abstract:

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.

US Classification:

252500, 427 77, 528 8, 977773

Abstract:

A family of carboxylic acid group containing fluorene/fluorenon copolymers is disclosed as binders of silicon particles in the fabrication of negative electrodes for use with lithium ion batteries. 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.

International Classification:

H01M 4/62

US Classification:

528220

Abstract:

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.

H01M 4/38

US Classification:

429211, 429220, 148269

Abstract:

A nanostructure on Cu comprising a plurality of Cu(OH)nanofibers wherein the nanofibers are formed by treating the Cu surface with ammonia solution to produce a layer of malachite on the Cu surface and treating the malachite coated Cu with NaOH aqueous solution to convert the malachite layer on the Cu surface into Cu(OH)nanofibers. The nanostructure may be formed on a Cu thin film. The thin film may be a layer of a laminated lithium ion battery.
