摘要： This invention relates generally to electrode materials, electrochemical cells employing such materials, and methods of synthesizing such materials. The electrode materials have a crystal structure with a high ratio of Li to metal M, which is found to improve capacity by enabling the transfer of a greater amount of lithium per metal, and which is also found to improve stability by retaining a sufficient amount of lithium after charging. Furthermore, synthesis techniques are presented which result in improved charge and discharge capacities and reduced particle sizes of the electrode materials.

摘要： Non-normal statistics applied to diffusivity calculations accelerate screening of ionic conductors for electrochemical devices such as electric storage batteries, fuel cells, and sensors. Displacements of atomic species within a crystalline structure for a candidate ionic conductor material are analyzed using a Skellam distribution optionally combined with Gaussian noise to calculate values for the standard deviation, upper error bound, and lower error bound for predicted values of diffusivity (D). When the predicted values of D have sufficient statistical precision, the diffusivity calculation is terminated and the calculated diffusivity is compared to a threshold value of diffusivity. When the threshold has been exceeded, the candidate ionic conductor may be listed as a preferred good conductor. When the calculated diffusivity fails to exceed the threshold, the material may be listed as a poor conductor and may be eliminated from further consideration.
