摘要： Battery cells are provided that can include: a housing defining a chamber having a fluid inlet and outlet; an anode at one side of the housing; a cathode at another side of the housing opposing and spaced apart from the anode a sufficient amount to allow for electrolyte between the anode and cathode; and the other side of the chamber defined by an ion permeable member. Methods for in situ battery electrode analysis are provided and these methods can include: providing a battery cell having an anode and a cathode; exposing the battery cell to an ion beam while the battery cell is operational to form secondary ions; and detecting the secondary ions to analyze the battery.

摘要： High energy density cathode materials, such as LiNixMnyCozO2 (NMC) cathode materials, with improved discharge capacity (hence energy density) and enhanced cycle life are described, A solid electrolyte, such as lithium phosphate infused inside of secondary particles of the cathode material demonstrates significantly enhanced structural integrity without significant or without any observable particle cracking occurring during charge/discharge processes, showing high capacity retention of more than 90% after 200 cycles at room temperature. In certain embodiments the disclosed cathode materials (and cathodes made therefrom) are formed using nickel-rich NMC and/or are used in a battery system with a non-aqueous dual-Li salt electrolytes.

摘要： Stabilized porous silicon particles are disclosed. The particles include a porous silicon particle comprising a plurality of interconnected silicon nanoparticles and (i) a heterogeneous layer comprising a discontinuous SiC coating that is discontinuous across a portion of pore surfaces and across a portion of an outer surface of the porous silicon particle, and a continuous carbon coating that covers outer surfaces of the discontinuous SiC coating, and remaining portions of the pore surfaces and the outer surface of the porous silicon particle, or (ii) a continuous carbon coating on surfaces of the porous silicon particle, including the outer surface and pore surfaces. Methods of making the stabilized porous silicon particles also are disclosed.
