Title: Surface modification agents for lithium batteries

Abstract

An active material for an electrochemical device may have a surface modification agent that is a silane, organometallic compound, or a mixture of two or more of such compounds. Both negative and positive electrodes may be prepared from the surface modified active materials. The surface of an electrode may be modified by adding the surface modification agent to a non-aqueous electrolyte used in constructing a battery. An electrode or active material may be modified with a surface modification agent in either the gas phase or in solution. Slurries of the active agent may be prepared and the surface modification agent added, the slurry then be used to cast an electrode that is then dried.

Anion binding agent lithium salts for battery electrolytes

Patent Orendorff, Christopher; Nagasubramanian, Ganesan; Fenton, Kyle R.; ...

A method for synthesizing a purified lithium (Li)+ anion binding agent (ABA-F)− salt and the corresponding Li+(ABA-F)− are disclosed. The method includes dissolving a boron-based acid in a polar solvent to form a solution. The solution is refluxed to form an anion binding agent. A stoichiometric amount of a small fluorinated salt, such as LiF, is added to the anion binding agent to form a mixture. The mixture is subsequently crystallized to obtain a substantially pure Li+(ABA-F)− salt. Example purified Li+(ABA-F)− salts include Ox-Li+(ABA-F), m-Li+(ABA-F), and BF3—Li+(ABA-F)−. These purified Li+(ABA-F)− salts provide the benefits of increased battery thermal safety withoutmore » loss of electrochemical performance. « less

Surface modifications for carbon lithium intercalation anodes

Patent Tran, Tri D [Livermore, CA]; Kinoshita, Kimio [Cupertino, CA]

A prefabricated carbon anode containing predetermined amounts of passivating film components is assembled into a lithium-ion rechargeable battery. The modified carbon anode enhances the reduction of the irreversible capacity loss during the first discharge of a cathode-loaded cell. The passivating film components, such as Li.sub.2 O and Li.sub.2 CO.sub.3, of a predetermined amount effective for optimal passivation of carbon, are incorporated into carbon anode materials to produce dry anodes that are essentially free of battery electrolyte prior to battery assembly.
