Abstract: The present invention provides a thermally-decomposable consolidated polymer particle encapsulated-electrode for a lithium-ion battery. The electrode includes polymer particles including at least one connection unit and at least one crosslinker in an amount of approximately 40% to 98% by weight and at least one binder material in an amount of approximately from 2% to 60% by weight. The consolidated crosslinked polymer particle coating results in a porous structure encapsulating the electrode. The pressure resistance of the consolidated crosslinked polymer particle coating ranges approximately from 0.5 to 8 MPa and the consolidated crosslinked polymer particle coating is decomposed to release a non-flammable gas and phosphorous-containing molecules so as to prevent thermal runaway at a temperature approximately from 300° C. to 500° C.

Abstract: A method for preparation of perovskite quantum dot (PQD)/polymer/ceramic ternary complex includes encapsulation of bifunctional coating including ceramic and polymer. Encapsulation sequence of polymer and ceramic may be altered according to the application. In one scenario, the perovskite quantum dots may be protected with ceramic coating first and further coated with polymer to obtain the perovskite/ceramic/polymer ternary complex. In another scenario, the perovskite quantum dots may be protected with polymer coating first and followed by ceramic coating to obtain the perovskite/polymer/ceramic ternary complex. The PQD ternary complex may provide synergistic effect on improvement of stability towards heat and moisture when compared to existing technology.

Abstract: The present application provides a lithium ion battery including a thermal sensitive layer comprising polymer particles. The thermal sensitive layer may be disposed between the electrodes and the separator. When the lithium ion battery is under thermal runaway condition and the internal temperature rises to a critical temperature, the polymer particles undergo a thermal transition process (melting) to form an insulating barrier on the electrodes, which blocks lithium ion transfer between the electrodes and shuts down the internal current of the battery.
