  • Patent number: 9960417
    Abstract: The present disclosure describes, among other things, new layered molybdenum oxides for lithium ion battery cathodes from solid solutions of Li2MoO3 and LiCrO2. These materials display high energy density, good rate capability, great safety against oxygen release at charged state due mostly to their low voltage. Therefore, these materials have properties desirable for lithium ion battery cathodes.

  • Patent number: 9904772
    Abstract: 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.
