摘要: An autonomic conductivity restoration system includes a solid conductor and a plurality of particles. The particles include a conductive fluid, a plurality of conductive microparticles, and/or a conductive material forming agent. The solid conductor has a first end, a second end, and a first conductivity between the first and second ends. When a crack forms between the first and second ends of the conductor, the contents of at least a portion of the particles are released into the crack. The cracked conductor and the released contents of the particles form a restored conductor having a second conductivity, which may be at least 90% of the first conductivity.

摘要: A process for preparing transition metal particles with a gradient in composition from the core of the particle to the outer layers. In particular, the process involves contacting a first transition metal solution with a second transition metal solution to form a transition metal source solution under specific process conditions. The transition metal particles with desired composition gradients are precipitated from the transition metal source solution. The transition metal particles may be combined with metals such as lithium to form cathode active metal oxides.

摘要: Primary and secondary Li-ion and lithium-metal based electrochemical cell systems. The suppression of gas generation is achieved through the addition of an additive or additives to the electrolyte system of respective cell, or to the cell itself whether it be a liquid, a solid- or plasticized polymer electrolyte system.

摘要: An active material for an electrochemical device may have a surface modification agent that is a silane, organometallic compound, or a mixture of two or more of such compounds. Both negative and positive electrodes may be prepared from the surface modified active materials. The surface of an electrode may be modified by adding the surface modification agent to a non-aqueous electrolyte used in constructing a battery. An electrode or active material may be modified with a surface modification agent in either the gas phase or in solution. Slurries of the active agent may be prepared and the surface modification agent added, the slurry then be used to cast an electrode that is then dried.
