A rechargeable lithium ion battery including: a positive electrode including coated particles, wherein each particle includes a core and a coating disposed thereon, wherein the core consists of Li, M, and O, and the coating includes Li, M, O, and AI2O3; wherein: M is (Ni(NiMn)Co)A; 0.15&#x2264;z&#x2264;0.50; 0.17&#x2264;x&#x2264;0.30; 0.35&#x2264;y&#x2264;0.75; 0&#x3c;k&#x3c;0.1; x+y+z=1; and A includes Al and optionally at least one additional metal dopant selected from Mg, Zr, W, Ti, Cr, V, Nb, B, and Ca, and combinations thereof; and wherein the Li and M are present in the core in a molar ratio of Li to M of at least 0.95 and no greater than 1.10; a negative electrode; and a nonaqueous liquid electrolyte including: a lithium salt; a nonaqueous solvent; and an additive mixture including: prop-1-ene-1,3-sultone; at least one compound selected from tris(trimethylsilyl)phosphite, tris(trimethylsilyl)phosphate, tri-allyl phosphate, and combinations thereof; and at least one compound selected from methylene methanedisulfonate, 1,3,2-dioxathiolane-2,2-dioxide, and combinations thereof.

Lithium ion batteries, electronic devices, and methods

A respiratory protection filter includes filtration media. The filtration media includes an iron-doped manganese oxide material having an average pore size (BJH method) in a range from 1 to 4 nm and a surface area (BET) of at least 300 m/g, or at least 350 m/g, or at least 400 m/g.

Filter media for respiratory protection

Provide are fluorinated cyclic and acyclic carbonate solvent compositions such as various fluorine substituted 1,3-dioxolane-2-one compounds and fluorine substituted 1,3-dioxane-2-one compounds, which are useful as electrolyte solvents for lithium ion batteries.

Fluorinated compounds for use in lithium battery electrolytes

Filter media that includes activated carbon particulates and zinc oxide particles disposed on surfaces of the activated carbon particulates. The zinc oxide particles have an average crystallite dimension that is not greater than about 50 nm.

Zinc oxide containing filter media and methods of forming the same

A lithium-ion battery has (a) an anode; (b) a cathode having a cathode composition of the formula Li[MMMn]O, wherein 0.083&#x3c;y&#x3c;0.5 with the proviso that Mand Mdo not include chromium, and wherein Mis Co and Mincludes the combination of Li and Ni; and (c) an electrolyte.

Cathode compositions for lithium-ion batteries

Powder milling techniques, tin-based alloys formed thereby, and the use of such alloys as electrode compositions for lithium ion batteries are provided. The alloys include tin and at least one transition metal but contain no silicon. The powder milling is done using low energy roller milling (pebble milling).

Method of making tin-based alloys for negative electrode compositions

Provided are negative electrode compositions for lithium-ion electrochemical cells that include metal oxides and polymeric binders. Also provided are electrochemical cells and battery packs that include electrodes made with these compositions.

Metal oxide negative electrodes for lithium-ion electrochemical cells and batteries

A filter for removing contaminants from air. The filter includes (a) a substrate that does not have any volatile ammonia on the surface thereof; (b) copper that has been impregnated onto the substrate; and (c) molybdenum and/or tungsten that has been impregnated onto the substrate. The filter can be made using an aqueous solution(s) that contains one or more of a first copper salt and a second salt that include a polynuclear anion that contains molybdenum, tungsten, or both. Because the metals can be impregnated onto the substrate surface without using an ammonium-based solution, the need to manage ammonia off-gassing is avoided. Further, no volatile ammonia would be present on the resulting substrate surface.

Ammonia-free gaseous air filter

A cathode composition for a lithium-ion battery having the formula Li[MMn]Owhere 0&#x3c;x&#x3c;1 and Mrepresents one or more metal elements, with the proviso that Mis a metal element other than chromium. The composition is in the form of a single phase having an O3 crystal structure that does not undergo a phase transformation to a spinel crystal structure when incorporated in a lithium-ion battery and cycled for 100 full charge-discharge cycles at 30&#xb0; C. and a final capacity of 130 mAh/g using a discharge current of 30 mA/g.

Compositions useful for cathodes in lithium-ion batteries are described. In some examples, an electrochemical cell includes an electrode, the electrode comprising a composition including the elements of Li, Fe, and F, where the composition includes a first phase including a disordered trirutile structure. Cathodes including such a composition may exhibit reversible reactivity with lithium. In some examples, this reaction takes place via an intercalation mechanism.

Cathode compositions for lithium-ion electrochemical cells

Overcharge protection is provided for rechargeable electrochemical lithium-ion cells. The electrolyte in the provided cells contains a cyclable redox shuttle molecule that can operate in cells with high voltage cathode materials.
