  • Block copolymer electrolyte for lithium batteries
    Patent number: 10854919
    Abstract: A solid polymer electrolyte for a battery is disclosed. The solid polymer electrolyte includes solid polymer electrolyte including a diblock copolymer AB or a triblock copolymer of the BAB type, in which block A is an unsubstituted polyethylene oxide chain having a number-average molecular weight less than 80,000 g/mol; block B is an anionic polymer prepared from one or more monomers selected from vinyl monomers and derivatives thereof to which is grafted an anion of lithium salt, and a second monomer having cross-linking functions.
    Type: Grant
    Filed: November 24, 2017
    Date of Patent: December 1, 2020
    Assignee: BLUE SOLUTIONS CANADA INC.

  • LITHIUM SALT GRAFTED NANOCRYSTALLINE CELLULOSE FOR SOLID POLYMER ELECTROLYTE
    Publication number: 20180131041
    Abstract: A solid polymer electrolyte for a battery is disclosed. The solid polymer electrolyte includes a polymer capable of solvating a lithium salt, a lithium salt, and nanocellulose in the form of nanofibers or nanocrystals onto which are grafted anions of lithium salt, the nanofibers or nanocrystals cellulose providing increased mechanical strength to the solid polymer electrolyte to resist growth of dendrites on the surface of the metallic lithium anode.
