Abstract: The invention discloses a method of manufacturing an electrochemical cell having a polymer separator membrane for separation of electrodes in the electrochemical cell, including providing a cathode and providing a polymer separator membrane. At least one cycle of irradiating the polymer separator membrane is performed by an energy beam under a radiation dose ranging between 50 and 200 kGy to effect a cross-linking in the polymer separator membrane. The polymer separator membrane is maintained at a temperature between 30° C. and 70° C. An anode is then provided. Subsequently, the polymer separator membrane is compressed between the cathode and the anode. An electrolyte is provided to form the electrochemical cell.

Abstract: The preset invention provides an electrode structure for a lithium ion battery comprising an electrode selected from a cathode including a lithium-based material or an anode including a conductive material, and a melt-convertible encapsulation layer covering at least one surface layer of the electrode. The melt-convertible encapsulation layer comprises a network of nanofibers having the diameter ranging approximately from 100 to 300 nm and polymer microspheres embedded in and coated on the nanofibrous network, wherein the ratio of the diameter of the polymer microspheres to the diameter of the nanofiber is over 30. The polymer microspheres melt to form a dielectric coating of the electrode so as to prevent fire or thermal runaway at a temperature approximately from 100 to 200° C.

Abstract: The present invention provides a rechargeable lithium-ion battery with an in situ thermally-curable electrolyte. The thermally-curable electrolyte is cured from the thermally-curable electrolyte precursor solution including a first crosslinking agent, a second crosslinking agent, an initiator, an electrolyte solvent, an electrolyte salt, one or more electrolyte additives, and one or more monomers or a monomer polymerization product. The viscosity of the thermally-curable electrolyte precursor solution is below 200 cps such that the thermally-curable electrolyte precursor solution is infiltrated within the separator and the pores inside the cathode and anode layers then cured to form porous separator and porous electrodes fully permeated with a solid electrolyte.

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.
