The disclosure provides a plurality of particles. Each particle may include a material comprising 0.95 to 1.30 mole fraction Li, at least 0.60 and less than 1.00 mole fraction Co, up to 10,000 ppm Al, 1.90 to 2.10 mole fraction O, and up to 0.30 mole fraction M, where M is at least one element selected from B, Na, Mg, P, Ti, Ca, V, Cr, Fe, Mn, Ni, Cu, Zn, Al, Sc, Y, Ga, Zr, Ru, Mo, La, Si, Nb, Ge, In, Sn, Sb, Te, and Ce. Each particle may also include a surface composition comprising a mixture of LiF and a metal fluoride. An amount of fluorine (F) is greater than 0 and less than or equal to 5000 ppm. The metal fluoride comprises a material selected from the group consisting of AlF, CaF, MgF, and LaF. The surface composition may also include a metal oxide comprising a material selected from the group consisting of TiO, MgO, LaO, CaO, and AlO. An amount of the metal oxide is greater than 0 and less than or equal to 20000 ppm.

Lithium fluoride-containing coatings for cathode active materials in Li-ion batteries

Compounds, particles, and cathode active materials that include lithium, cobalt, manganese, nickel, aluminum, and other elements can be used in lithium ion batteries. The cathode active materials include compounds having the general Formula (I): compound represented by Formula (I): LiCOMeMnNiAlO, as well as Formula (II): LiCOMeMnNiAlO.

Straw lid

A roadway renewable energy generation system and method, that includes a plurality of plunger devices, electrically connected in series, and each plunger device configured to generate a predetermined amount of electricity, through reciprocating linear motion, when actuated by an object; a plurality of grooves formed within a ground surface configured to house the plurality of plunger devices therein, wherein a top portion of each plunger device extends a predetermined distance above the ground surface; a transformer configured to transform the electricity generated by the plurality of plunger devices; and a storage device configured to store the electricity from the transformer. The system is embedded into roadways and parking garages/ramp entrances, for example, to enable electricity generated when each plunger device is depressed as the vehicle tires pass over the roadways to be stored and reused for electric vehicles and power/utility grids.
