  • Publication number: 20240097201
    Abstract: A manufacturing method for a secondary battery disclosed herein includes: a first step of manufacturing a wound electrode body with a flat shape by stacking a first separator, a positive electrode, a second separator, and a negative electrode and winding the stack; a second step of disposing the wound electrode body in a battery case; and a third step of injecting an electrolyte solution into the battery case. In the first step, the wound electrode body is manufactured in a manner that when peel strength between the first separator and the negative electrode is A (N/m) and peel strength between the second separator and the negative electrode is B (N/m), a difference between the peel strength A and the peel strength B is 0.5 (N/m) or more.

  • Patent number: 11931936
    Abstract: In an injection process, molten resin is successively injected from a first flow channel and a second flow channel connected with each other in order into a cavity of a metal mold. High-temperature resin existing in the first flow channel is injected in advance into the cavity as a part of a single shot of molten resin to later form a skin layer of a molded article. Other low temperature resin near a flowable limit existing in the second flow channel is subsequently injected into the cavity as another part of the single shot of molten resin to later form a core layer of the molded article. A low temperature resin remaining in the first flow channel when injection is completed is warmed to be a high-temperature resin before the next cycle, thereby allowing successive molding of molded articles.

  • Patent number: 11886294
    Abstract: A first node group including at least three nodes is predefined in a distributed storage system. Each node of the first node group is configured to send data blocks stored in storage devices managed by the node to other nodes belonging to the first node group. A first node is configured to receive data blocks from two or more other nodes in the first node group. The first node is configured to create a redundant code using a combination of data blocks received from the two or more other nodes and store the created redundant code to a storage device different from storage devices holding the data blocks used to create the redundant code. Combinations of data blocks used to create at least two redundant codes in redundant codes created by the first node are different in combination of logical addresses of constituent data blocks.
