Abstract: A secondary battery includes a power generation element including a plurality of electrodes. The electrodes are stacked on each other in a stacking direction with a separator interposed therebetween. Each of the electrodes includes a current collector led out in a first direction intersecting the stacking direction. Each of a plurality of current collectors led out in the first direction includes an end part, and the end part includes a first bent part that is bent in a second direction intersecting the first direction. Each of a plurality of first bent parts overlaps and is in contact with an adjacent first bent part in the second direction.

Abstract: A protection method for a secondary battery includes evacuating the secondary battery through an injection opening of the secondary battery to within 100 kPa, introducing a first reactant into the secondary battery through the injection opening until a pressure of the secondary battery rises by more than 1 Pa and maintaining the pressure for more than 1 ms, evacuating the secondary battery through the injection opening to within 100 kPa, and introducing a second reactant into the secondary battery through the injection opening until the pressure rises by more than 1 Pa and maintaining the pressure for more than 1 ms, thereby forming a protection layer on an internal surface of the secondary battery.

Abstract: A method for producing a power storage device includes: compressively deforming in which case long-side walls of the power storage device after initial charging and aging but before permanent sealing are pressed toward an electrode body to compress the electrode body and further plastically deform at least one of the case long-side walls so that the case long-side walls continue to press the electrode body even after the pressing is released; after this compressively deforming, hermetically permanently sealing the case of the power storage device in which the inside of the case is in communication with the outside; and releasing the pressing applied in the compressively deforming.

Abstract: Methods of fabricating electrochemical cells employing polymeric support systems rather than metal-based materials as a protective mechanism against mechanical and electrical damage include assembling components of the electrochemical cell. In addition to an anode, a cathode, and a porous separator, the components include a continuous network of precursors of a polymer support system. The continuous network is arranged in continuous pathway(s) extending throughout the interior of the electrochemical cell. Batteries may be provided with the continuous network of precursors in place, i.e., uncured, and curing may be performed post-fabrication and/or sale. Alternatively, curing may be performed during fabrication (or prior to sale), resulting in a continuous network of polymeric pathways extending throughout the volume of the cell and providing mechanical strength, e.g., by penetrating and physically coupling the various components of the cell. Curing may be performed using various mechanisms, including thermal, kinetic, chemical, and optical.
