Abstract: Disclosed is a process for producing a battery material including contacting a first intermediate product of a battery material with an acidic medium under conditions sufficient to dissolve low-lithium-containing oxide present on a surface of the first intermediate product to obtain a second intermediate product such that a weight of the second intermediate product is 0.2% to 5% less than a weight of the first intermediate product.

Abstract: Disclosed is a process for removing impurities from an intermediate product in battery material production including a) contacting a first intermediate product with a first aqueous medium to obtain a second intermediate product; and b) contacting the second intermediate product with a stream of a second aqueous medium until a conductivity of the stream of the second aqueous medium after contacting the second intermediate product is below about 1,000 micro-Siemens per centimeter (?S/cm).

Abstract: Provided are processes for the formation of electrochemically active materials such as lithiated transition metal oxides that solve prior issues with throughput and calcination. The processes include forming the materials in the presence of a processing additive that includes potassium prior to calcination that produces active materials with increased primary particle grain sizes.

Abstract: Disclosed herein are methods of recycling elements, such as, e.g., lithium and/or nickel, from a solution, such as, e.g., methods of recovering reusable lithium and nickel from a waste stream produced by the delithiation of a lithium nickel oxide material.

Abstract: Disclosed herein are processes for isolating purified water from a waste stream, such as, e.g., a waste stream formed in the manufacture or recycling of batteries, and further e.g., processes for isolating purified water suitable for use in downstream industrial processes from a waste stream generated during delithiation of a lithium metal oxide material.

Abstract: Provided are processes of removing lithium from an electrochemically active composition. The process of removing lithium from an electrochemically active composition may include providing an electrochemically active composition and combining the electrochemically active composition with a strong oxidizer optionally at a pH of 1.5 or greater for a lithium removal time. The electrochemically active composition may include Li, Ni, and O. The electrochemically active composition may optionally have an initial Li/M at % ratio of 0.8 to 1.3. According to some embodiments of the present disclosure, the lithium removal time may be such that a second Li/M at % ratio following the lithium removal time is 0.6 or less, thereby forming a delithiated electrochemically active composition.

Abstract: A high silica glass composition comprising about 82 to about 99.9999 wt. % SiO2 and from about 0.0001 to about 18 wt. % of at least one dopant selected from Al2O3, CeO2, TiO2, La2O3, Y2O3, Nd2O3, other rare earth oxides, and mixtures of two or more thereof. The glass composition has a working point temperature ranging from 600 to 2,000° C. These compositions exhibit stability similar to pure fused quartz, but have a moderate working temperature to enable cost effective fabrication of pharmaceutical packages. The glass is particularly useful as a packaging material for pharmaceutical applications, such as, for example pre-filled syringes, ampoules and vials.
