Abstract: A flexible battery and method of manufacturing thereof are provided. An example flexible battery may include a first current collector comprising a first copper plate, an anode layer disposed on the first current collector, a second current collector comprising a second copper plate, a cathode layer disposed on the second current collector, and a separator layer comprising a polymer material. The anode layer may comprise a composite of thermoplastics, silver powder, and potassium hydrogen carbonate. The cathode layer may comprise a composite of thermoplastics and a freshly prepared zinc hydroxide. The separator layer can be impregnated with an electrolyte comprising an aqueous solution of potassium hydroxide, lithium hydroxide, potassium zincate, and modifying additives. The modifying additives may include a monobasic organic acid, a dibasic organic acid, and a tribasic organic acid as anion donors, and one or more complexones as cation electron acceptors.

Abstract: Methods and systems for heating of heated clothing are provided. An example system may include system comprising one or more heating components placed within one or more zones of the heated clothing and configured to receive electrical current from one or more voltage converters independently. The system may also include a battery configured to provide power to the voltage converters. The system may also include a controller configured to control an output voltage of the one or more voltage converters, wherein the output voltage is provided to the one or more heating components. The controller may be configured to receive temperatures from the temperature sensors located in heating components, an ambient temperature from the ambient temperature sensor, and user-defined temperatures. The controller may adjust the output voltage based on the temperatures received from the temperature sensors and adjust ambient temperature and user-defined temperatures.
