摘要： A method for filling a thermal paste into a battery module. The battery module includes a module housing with at least one cooling wall, at which a cooling plate can be arranged outside the module housing. At least one stack is formed by a plurality of uniformly stacked pouch cells. The at least one stack is arranged at the at least one cooling wall in the module housing. In proximity to at least one opening, a fold of at least one pouch cell is folded over toward the surface of pouch cell and glued, thereby forming a first flow channel between a stack cooling side and the cooling wall. The thermal paste is filled in through the opening and the thermal paste spreads homogeneously in the first flow channel.

摘要： A refuelable electrochemical battery or cell is provided that features three phases of operation that repeat cyclically. In an intake phase, electrochemically active particles that are at least partially magnetic and a suitable electrolyte are admitted or fed into a cell cavity. In a power phase, oxidation and reduction reactions produce electrical energy while an electromagnet and/or permanent magnet attract the particles toward one electrode. A gas-diffusion membrane permeable by oxygen operates in conjunction with another electrode. During the exhaust phase, a piston forces residue of the reaction from the cavity to prepare for the next cycle of operation.

摘要： Corrosion mitigation in a battery may include displacing a first flowable medium with a second flowable medium along a first electrode to interrupt fluid communication of the first flowable medium with the first electrode—thus interrupting operation of the battery—while a second electrode remains in contact with a flowable medium (e.g., one or more of the first flowable medium or another flowable medium, such as a gel). For example, a membrane (e.g., an underwater oleophobic material) may be disposed between the first electrode and the second electrode. An oil may displace an aqueous electrolyte on a first side of the membrane toward a metallic electrode while the aqueous form of the electrolyte remains in contact with an air electrode on a second side of the separator membrane disposed toward the air electrode.

摘要： A metal-air battery includes a metal negative electrode (12), an oxygen-generating electrode placed on a surface of the metal negative electrode, and an air electrode placed on another surface of the metal negative electrode. The metal negative electrode includes at least a negative electrode active material layer facing the oxygen-generating electrode. A first separator placed in contact with the negative electrode active material layer is placed between the negative electrode active material layer and the oxygen-generating electrode.
