The invention relates to a secondary particle for a cathode of a secondary lithium battery cell that comprises a plurality of primary particles, each having a layered crystalline structure in which transition metal oxide layers and lithium layers alternate. Each of the primary particles has a spatial extension in the direction of its crystallographic c-axis that is greater than in a direction perpendicular to this axis. The invention also relates to a method for producing such a particle.

Secondary particle for a cathode of a secondary lithium battery cell and method for producing such a particle

A manufacturing process includes: depositing a catalyst support on a gas diffusion layer to form a catalyst support-coated gas diffusion layer; depositing a catalyst on the catalyst support-coated gas diffusion layer to form a catalyst-coated gas diffusion layer; and depositing an ionomer on the catalyst-coated gas diffusion layer to form an ionomer-coated gas diffusion layer. A membrane electrode assembly for a fuel cell includes: a gas diffusion layer; a polymer electrolyte membrane; and a catalyst layer disposed between the gas diffusion layer and the polymer electrolyte membrane, wherein the catalyst layer includes an ionomer, and a concentration of the ionomer varies within the catalyst layer according to a concentration profile.

Approaches, techniques, and mechanisms are disclosed for predicting molecular electronic structural information. According to one embodiment, quantum simulation results are generated for a molecule based on a quantum simulation of an electronic structure of the molecule. The quantum simulation of the electronic structure of the molecule is performed with quantum processing units. An input vector comprising data field values derived from the quantum simulation results for the molecule is created. An electronic structural information prediction model is applied to generate, based at least in part on the input vector, predicted electronic structural information for the molecule.

A catalyst structure includes: (1) a substrate; (2) a catalyst layer on the substrate; and (3) an adhesion layer disposed between the substrate and the catalyst layer. In some implementations, an average thickness of the adhesion layer is about 1 nm or less. In some implementations, a material of the catalyst layer at least partially extends into a region of the adhesion layer. In some implementations, the catalyst layer is characterized by a lattice strain imparted by the adhesion layer.
