  • 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.
