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: Lithium ion batteries with improved fire resistance properties are described. The lithium ion battery includes a first electrode including a lithium compound and a second electrode. A separator is positioned between the first electrode and the second electrode and an electrolyte is provided. wherein the separator comprises at least a layer of polymeric nanofibers positioned on one side of a separator core and a fire-retardant polymer coating formed opposite to the nanofiber layer which is simultaneously deposited during electrospinning process. The polymeric nanofibers have a diameter less than approximately 1 micron. The polymeric nanofibers have a fire-retardant material entrapped within the nanofibers. The fire-retardant material has a lower melting point than the polymeric nanofibers. The separator/nanofibers/fire-retardant material are configured such that a fire-initiating event releases the entrapped fire-retardant material from the nanofibers which extinguishes the fire-initiating event.

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.
