  • Patent number: 11322748
    Abstract: A method of forming a metal oxy-fluoride surface on lithium metal oxide cathode material particles is disclosed. Such a metal oxy-fluoride surface may help to prevent lithium metal oxide cathode active materials from reacting with water, thus enabling aqueous processing of cathodes made from such materials in the manufacture of lithium batteries. Such a method may also reduce lithium battery manufacturing costs and time by substituting water for currently-used organic solvents that are expensive and require special handling and disposal. Such a method may also reduce the cost of lithium metal oxide cathode active materials as the requirements for moisture-free manufacture, storage, and processing will be reduced or eliminated.

  • Publication number: 20210351402
    Abstract: Commercially-available lithium metal foils have been found to have a high density of crystalline defects. When such foils are used as the anode in a secondary lithium metal battery cell, repeated cycling may lead to the formation of lithium shunts near the crystalline defects, which can cause shorting. Methods described herein may be used to reduce the density of crystalline defects in lithium metal foils. Such lithium metal can be used as the anode in lithium battery cells.

  • Patent number: 11088362
    Abstract: In this disclosure, we describe a new chemical treatment that can be performed on lithium metal and lithium alloy surfaces to selectively remove LiH defects. This treatment utilizes an exclusive reaction between LiH and trialkyl borane to form lithium borohydride complexes, which can be easily washed away from surface using an inert organic solvent. This treatment can be useful for lithium metal and lithium alloy anodes for high energy batteries.

  • Patent number: 10879563
    Abstract: A novel solid block copolymer electrolyte material is described. The material has first structural polymer blocks that make up a structural domain that has a modulus greater than 1×107 Pa at 25° C. There are also second ionically-conductive polymer blocks and a salt that make up an ionically-conductive domain adjacent to the structural domain. Along with the second ionically-conductive polymers, there is also a crosslinked network of third polymers, which interpenetrates the ionically-conductive domain. The third polymers are miscible with the second polymers. It has been shown that the addition of such an interpenetrating, crosslinked polymer network to the ionically-conductive domain improves the mechanical properties of the block copolymer electrolyte with no sacrifice in ionic conductivity.
