Abstract: A surface coating method and a method for reducing irreversible capacity loss of a lithium rich transitional oxide electrode are disclosed herein. In an example of the surface coating method, a dispersion of a lithium rich transitional oxide powder and an oxide precursor or a phosphate precursor in a liquid is formed. The liquid is evaporated. The forming and evaporating steps are carried out in the absence of air to prevent precipitation of the oxide precursor or the phosphate precursor. Hydrolyzation of the oxide precursor or the phosphate precursor is controlled under predetermined conditions, and an intermediate product is formed. The intermediate product is annealed to form an oxide coated lithium rich transitional oxide powder or the phosphate coated lithium rich transitional oxide powder.

Abstract: A method of operating a vehicle powertrain includes determining a selected powertrain operational mode. A demand fraction is determined. An internal combustion engine (ICE) is to output a maximum power when a gaseous fuel is conveyed to an injector of the ICE at a source pressure greater than a cutoff pressure. The source pressure in a container in fluid connection with the injector is determined. The gaseous fuel is received at the source pressure by the injector to inject the gaseous fuel into the ICE for combustion in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a first set of criteria. The injector is prevented from injecting the gaseous fuel into the ICE and the powertrain is driven from an alternative power source in response to the source pressure, demand fraction, or selected powertrain operation mode meeting a second set of criteria.

Abstract: A method for increasing capacity of a natural gas (NG) tank. The method includes selecting a container with a service pressure rating of about 3,000 or 3,600 psi. An NG adsorbent is in the container. The container has a maximum fill capacity. The method further includes cooling the adsorbent by Joule-Thomson cooling during filling of the container with NG from a filling source at greater than 3,600 psi. The container is filled to the maximum fill capacity at a fill rate to prevent a bulk temperature of the adsorbent from rising more than about 5° C. above an ambient temperature. A rate of heat transfer from the tank is less than a rate of heating from compression of the NG and adsorption during the filling. The NG adsorbent adsorbs a higher amount of NG than it would at higher than 5° C. above ambient.
