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: 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: A bendable wireless charging apparatus having an operational bend radius of approximately 90 degrees is disclosed, which includes a flexible substrate, a receiving coil, a battery, a flexible EMI-shielding layer and a control module. The receiving coil is disposed on a surface of the substrate, and is electrically connected to the control module. The battery, which may also be flexible, is located beneath another surface of the substrate. The EMI-shielding layer is disposed between the receiving coil and the battery.
