Apparatus and methods of forming a battery-active material are described. An apparatus includes a first processing section that raises the temperature of a precursor material to a reaction threshold temperature, a second processing section that converts the precursor material to a battery-active material, and a third processing section that cools the resulting battery-active material. Each of the processing sections may be a continuous flow tubular component. The first and third processing sections may be metal, and the second processing section may be a refractory material for high temperature service. The battery-active material is collected using a solids collector.

Compositions and methods of forming battery active materials are provided. A solution of battery active metal cations and reactive anions may be blended with a fuel to yield a precursor mixture usable for synthesizing a battery active material for deposition onto a substrate. The battery active metal cations include lithium, manganese, cobalt, nickel, iron, vanadium, and the like. Reactive anions include nitrate, acetate, citrate, tartrate, maleate, azide, amide, and other lower carboxylates. Suitable fuels, which may be water miscible, may include amino compounds. Alcohols and sugars may be added to adjust carbon content and fuel combustion characteristics. An exothermic reaction is performed to convert the metals into battery active oxides.

An electronic device includes a battery and a battery management system. The battery management system is configured to derive a predicted battery demand based on observed usage patterns to predictively charge the battery to healthily accommodate the predicted battery demand. The battery management system is further configured to determine a predicted deviating battery demand based on a contextual signal. The predicted deviating battery demand differing from the predicted battery demand. The battery management system is further configured to predictively charge the battery to healthily accommodate the predicted deviating battery demand.

Examples are disclosed herein that relate to curved batteries. One example provides a battery comprising an anode arranged on an anode substrate, a cathode arranged on a cathode substrate, the anode substrate being curved at a first curvature and the cathode substrate being curved at a second curvature, and a separator between the anode and the cathode. A thickness of the anode substrate and a thickness of the cathode substrate are determined based on the curvature of the respective substrate, such that the one of the anode substrate and the cathode substrate with a larger curvature has a larger thickness.

Examples disclosed herein relate to a continuous separator having perforations to help reduce or prevent wrinkling of the separator when producing curved electrode stacks. One example provides a battery comprising a plurality of discontinuous electrode layers, and a continuous separator separating the discontinuous electrode layers, the continuous separator having perforations extending at least partially through a depth of the continuous separator in a folded region of the continuous separator.
