Abstract: A cathode material has the chemical formula Li4+?Mx1M?y1M?z1O8 or Li2+?Mx2M?y2M?z2O4 where 0???1, x1, y1, z1 are integers (+/?0.5) and x1+y1+z1=4, and x2, y2, z2 are integers (+/?0.05) and x2+y2+z2=2. A method for discovering a cathode material includes estimating synthesizability for a plurality of cathode material compositions, selecting a first subset of cathode material compositions from the plurality of cathode material compositions as a function of the estimated synthesizability and metal-ion diffusion availability, estimating voltage discharge, charge capacity, and oxygen stability for the first subset of cathode material compositions, and selecting a second subset of cathode material compositions from the first subset plurality of cathode material compositions as a function of the estimated voltage discharge, charge capacity, and oxygen stability.

Abstract: A cathode for a battery includes a cathode material with the chemical formula Li1+?FexCryO2 where 0???1, and ?+x+y=2. In some variations, the cathode material has a disordered rock-salt crystal structure and the chemical formula Li1+?FexCryO2 where 0???1, and ?+x+y=2. And in at least one variations, a method of forming the cathode material includes wet ball milling solid precursors of lithium, iron, and chromium and forming a slurry, drying the slurry and forming a powder, sintering the powder, and dry ball milling the powder and forming the cathode material with the disordered rock-salt crystal structure and the chemical formula Li1+?FexCryO2 where 0???1, and ?+x+y=2.

Abstract: The invention relates to an improved cast Al alloy designed to provide an accelerated response to heat treatment; specifically, the alloy's response to thermal growth during aging is accelerated, leading to a dimensionally more stable casting. This improvement is achieved by the addition of trace amounts of Sn, In, Ge or Cd to an Al—Si—Cu cast alloy. The improved alloy has particular application for cast Al engine blocks and cylinder heads.
