  • Patent number: 11728521
    Abstract: Disclosed are a system and methods for preventing dendrite growth in an electrochemical cell through the use of a protective layer. The electrochemical cell may comprise an anode, a cathode, an electrolyte, and a protective layer, wherein the protective layer is capable of producing a voltage. The voltage produced can selectively shield metal ions from certain regions of the protective layer. This shielding can result in a more uniform flux of metal ions being transferred across the electrode-electrolyte interface in subsequent electrodeposition and electrodissolution processes. As a result, an electrode with such a protective layer can exhibit improved performance and durability, including markedly lower overpotentials and largely improved metal (e.g., lithium) retention.

  • Patent number: 9281548
    Abstract: A battery module is provided. The battery module includes a plurality of battery cell assemblies configured to electrically communicate with each other. Each battery cell assembly has an electrode stack enclosed by a case. The electrode stack is positioned in the case to form one or more peripheral spaces between the electrode stack and the case. Support members are positioned adjacent to each of the battery cell assemblies to contact a desired portion of the electrode stack. The support members are configured to focus a compressive force on a desired portion of the electrode stack. The compressive force urges gases formed during operation of the electrode stack into the peripheral spaces within the case.

  • Patent number: 9196919
    Abstract: A secondary battery, including an electrode assembly having a positive sheet and a negative sheet and a separator is interposed therebetween; a tape to wrap an outer surface of the electrode assembly; and a case to receive the electrode assembly. After a remainder of the tape is formed to extend beyond a lower surface of the electrode assembly and joined by a press, the remainder is positioned between a bottom surface of the case and the lower surface of the electrode assembly. According to the embodiment of the present invention, since a junction portion of the tape extended to the outside of the lower surface of the electrode assembly is bent and inserted into the case, a shock-absorbing action is provided to reduce an external shock applied to the secondary battery. Further, an additional tape process can be omitted to simplify a manufacturing process of the secondary battery.

    Abstract: An electricity accumulation device includes an electricity accumulation element, an outer jacket material configured to house the electricity accumulation element, and a deformation sensor disposed on an expansive surface of the outer jacket material. The deformation sensor includes a sensor membrane having a base material made of an elastomer or a resin and conductive fillers filling the base material, the sensor membrane being subjected to bending deformation along with expansion of the outer jacket material, and a pair of electrodes connected to the sensor membrane. A three-dimensional conductive path is formed in the sensor membrane through contact between the conductive fillers. An electric resistance is increased along with an increase in amount of deformation of the sensor membrane from a natural state. The electricity accumulation device senses expansion of the outer jacket material on the basis of variations in electric resistance along with bending deformation of the sensor membrane.
