Abstract: An anode for an energy storage device includes a current collector having an electrically conductive layer and a surface layer overlaying the electrically conductive layer. A lithium storage layer may overlay the surface layer. The surface layer may include manganese. The lithium storage layer may include at least 40 atomic % silicon, germanium, or a combination thereof.

Abstract: A method of recovering purified partly-hydrolyzed cellulose particles from a composition comprising agglomerated partly-hydrolyzed cellulose particles and an acid, using electrodialysis. The invention addresses the problem of reducing the acid to very low levels while avoiding the high capital and operating costs, high water usage and large filtration surface area or dilution time requirements of the prior art processes. Following dilution, concentration by centrifuging or settling, and/or dialysis of the composition, the composition is treated in an electrodialysis cell to remove ions, such as free sulfate from sulfuric acid. The method may include having an anion exchange resin in the feed compartment of the electrodialysis cell, adding a base to the receiving solution in the electrodialysis cell, and a second step of electrodialysis of the purified partly-hydrolyzed cellulose particles.

Abstract: The invention describes processes for the production of basic aluminum compounds, including aluminum chlorohydrate, basic zirconium compounds, and basic aluminum zirconium compounds. The process produces products of a wide range of basicities. The products formed by the present invention are comprised of low molecular weight species characteristic of enhanced efficacy antiperspirant salt compositions. The products of this process are suitable for use as water purification agents, as binders in catalyst applications, and in antiperspirant applications. In addition, the invention is directed to the products made by the disclosed process.

Abstract: The invention relates generally to processes for the production of high-basicity and ultra-high basicity polyaluminum chlorides including aluminum chlorohydrate. The processes can produce products of a wide range of basicities and are particularly useful in producing high basicity products. The process can produce a wide range of solution concentrations and are particularly useful in producing high solution concentrations. The processes described generate high purity products, which are free of by-product salt(s). The processes described herein can also be utilized to produce enhanced efficacy polyaluminum chlorides including aluminum chlorohydrate. When compared to conventional processes for manufacturing these compounds the processes disclosed herein are unique in so far as the disclosed processes do not require aluminum metal as a starting material. The products of the processes are suitable in applications including water purification, catalysts, and antiperspirants.

Abstract: A system for screening and measuring the effectiveness of catalysts, comprising an electrolytic cell having a counter electrode comprising a plurality of segmented anodes, each of the anodes electrically isolated from each other, and a catalyst support adapted for holding an associated plurality of cathodes, where each cathode is operatively arranged to function as a working electrode when a discrete catalyst is deposited thereon, wherein the catalyst support positioned between the counter electrode and the working electrodes, and, means for measuring current in each of the plurality of segmented anodes, where the current is an indication of effectiveness of each discrete catalyst.
