  • Polymer binder with high peel strength and application thereof in secondary lithium battery
    Patent number: 11777093
    Abstract: A polymer binder with high peel strength is used in a secondary lithium battery. The polymer binder is obtained by a ring-opening reaction of polyvinylene carbonate by a nucleophile. The polyvinylene carbonate accounts for 10-90% of the total mass of the polymer binder while the nucleophile accounts for 10-90% of the total mass of the polymer binder. The polymer binder has high peel strength (0.02-0.6 N/mm) and high decomposition voltages (4.5-6.0 V), and can be used as an electrode material binder in a secondary lithium battery.

  • POLYOXYMETHYLENE-BASED ALL-SOLID-STATE POLYMER ELECTROLYTE PREPARED BY IN-SITU RING-OPENING POLYMERIZATION AND APPLICATION
    Publication number: 20220328873
    Abstract: A polyoxymethylene-based all-solid-state polymer electrolyte prepared by in-situ ring-opening polymerization is used in forming an all-solid-state secondary lithium battery. A trioxymethylene monomer, an additive and lithium salt initiates in-situ ring-opening polymerization on a porous support material through a catalyst to form the all-solid-state polymer electrolyte, which has a thickness of 10 ?m-800 ?m, an ionic conductivity of 4×10?5 S/cm—8×10?3 S/cm at room temperature and an electrochemical window not lower than 4.2 V.
