Abstract: A quasi-solid-state battery formed from non-gas evolving in-situ curing of a quasi-solid-state electrolyte that includes a high swelling polymer made from a monomer with good compatibility with liquid electrolytes, and has a good reactivity for facile non-gas evolving in-situ polymerization. The monomer can be based on acrylate polymerization chemistry or an allyl group polymerization chemistry. Non-gas evolving initiators are used for non-gas evolving in-situ polymerization of acrylate or allyl monomer-based QSE. The resulting QSE additionally has high ionic conductivity, allowing for a high battery output, and a wide electrochemical window (stable for lithium metal anode and high-voltage cathodes). The resulting quasi solid electrolyte battery is not only easy to fabricate using conventional battery manufacturing practices, the non-gas evolving in-situ polymerization causes the QSE to be uniformly distributed within the battery, ensuring high-quality, safe battery performance and longevity.

Abstract: A lithium-based battery including an electrolyte having at least two lithium salts selected from LiPF6, LiTFSI, LiFSI or LiBF4, along with a further lithium salt additive. Through the selection of particular lithium salt combinations, a high lithium ion concentration in the electrolyte is maintained. The battery includes a cathode, an anode, and a porous polymer separator. The lithium-based battery has reliable capacity retention at high discharge rates, such as 10C to 15C.

Abstract: A solventless method of making a dry electrode for an electrochemical cell is provided. A solventless electrode material mixture includes 85-99% electrode active material and from 0-10% conductive carbon additive. A polymer binder system is present from 1-15%. The polymer binder system includes one or more polymer binders. The electrode material mixture is mixed at a temperature greater than a softening point or a melting point of at least one polymer binder of the polymer binder system. The electrode material mixture is kneaded into an electrode material dough. The electrode material dough is formed into an electrode material sheet. At least a portion of the electrode material sheet is affixed to a metal current collector to form an electrode.

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 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.
