20120088155 | ALGINATE-CONTAINING COMPOSITIONS FOR USE IN BATTERY APPLICATIONS - A silicon-based anode comprises an alginate-containing binder. The many carboxy groups of alginate bind to a surface of silicon, creating strong, rigid hydrogen bonds that withstand battery cycling. The alginate-containing binder provides good performance to the anode by (1) improving the capacity of the anode in comparison to other commercially-available binders, (2) improving Columbonic efficiency during charging and discharging cycles, and (3) improving stability during charging and discharging cycles. | 04-12-2012 |
20120244391 | Silicon-Based Anode and Method for Manufacturing the Same - A silicon-based anode comprising silicon, a carbon coating that coats the surface of the silicon, a polyvinyl acid that binds to at least a portion of the silicon, and vinylene carbonate that seals the interface between the silicon and the polyvinyl acid. Because of its properties, polyvinyl acid binders offer improved anode stability, tunable properties, and many other attractive attributes for silicon-based anodes, which enable the anode to withstand silicon cycles of expansion and contraction during charging and discharging. | 09-27-2012 |
20130224594 | Core-Shell Composites for Sulfur-Based Cathodes in Metal-Ion Batteries - A battery cathode electrode composition is provided comprising core-shell composites. Each of the composites may comprise a sulfur-based core and a multi-functional shell. The sulfur-based core is provided to electrochemically react with metal ions during battery operation to store the metal ions in the form of a corresponding metal-sulfide during discharging or charging of the battery and to release the metal ions from the corresponding metal-sulfide during charging or discharging of the battery. The multi-functional shell at least partially encases the sulfur-based core and is formed from a material that is (i) substantially permeable to the metal ions of the corresponding metal-sulfide and (ii) substantially impermeable to electrolyte solvent molecules and metal polysulfides. | 08-29-2013 |
20130344391 | MULTI-SHELL STRUCTURES AND FABRICATION METHODS FOR BATTERY ACTIVE MATERIALS WITH EXPANSION PROPERTIES - Battery electrode compositions are provided comprising core-shell composites. Each of the composites may comprise, for example, an active material, a collapsible core, and a shell. The active material may be provided to store and release metal ions during battery operation, whereby the storing and releasing of the metal ions causes a substantial change in volume of the active material. The collapsible core may be disposed in combination with the active material to accommodate the changes in volume. The shell may at least partially encase the active material and the core, the shell being formed from a material that is substantially permeable to the metal ions stored and released by the active material. | 12-26-2013 |
