A lattice energy converter (LEC) is disclosed that produces ionizing radiation and/or electricity based on the thermal energy in the lattice of a specially prepared working electrode comprised in whole or in part of hydrogen host materials that are occluded with hydrogen or the isotopes of hydrogen and wherein the hydrogen host materials may include vacancies, superabundant vacancies, and other lattice defects. When the hydrogen host material is occluded with hydrogen, the LEC was found to self-initiate the production of ionizing radiation and, when the hydrogen host materials are in fluidic contact with a gas or vapor containing hydrogen or isotopes of hydrogen, the LEC was found to self-sustain the production of ionizing radiation. When the LEC includes one or more additional electrodes or electrode structures, the ionizing radiation was found to be converted to electrical energy. Materials that are normally considered to be radioactive are not required.

A battery box, a battery, an electric device, and a method and device for manufacturing battery are provided. The battery box includes a support member and an expansion member. The expansion member presses the support member so that the volumetric capacity of an accommodating space for accommodating binder between the support member and the battery cell changes. The volumetric capacity of the accommodating space can be adjusted. Therefore, under the condition that the accommodating space has a relatively large volumetric capacity, it is simple to inject an appropriate amount of binder; and after the binder is injected, the volumetric capacity of the accommodating space is reduced so that the binder spreads throughout the accommodating space. The foregoing box allows for binder injection reduction during battery assembly, thereby reducing the possibility of binder overflow, improving the safety performance of the battery, and also increasing the energy density of the battery.

This invention relates to a robust optimal design method for photovoltaic cells. Firstly, the deterministic optimal model is established, which is solved by Monte Carlo method to obtain the maximum output power value of optimization objective and its corresponding design variable value, and then the design variable value obtained from deterministic optimization is deemed as the initial point of the mean value of the robust optimal design variable. Later, the robust optimal model is solved by Monte Carlo method in order to obtain the mean value of design variable, and then appropriate materials and manufacturing techniques are selected for corresponding photovoltaic components according to the design variable obtained, so as to achieve the robust optimal design of photovoltaic cells. In fact, this invention improves the output stability and reliability of photovoltaic cells.

A separator for a bobbin-style electrochemical cell is inserted into an interior opening within a ring-shaped cathode in an electrochemical cell can. An expansion force is then applied to an interior surface of the separator to press the separator against the interior walls of the cathode. A tool may then remove various creases and/or wrinkles in the separator and/or may then heat seal at least a portion of the tubular walls of the separator to minimize the void space between the separator and active material (e.g., cathode and/or anode) within the electrochemical cell.
