  • Patent number: 10873102
    Abstract: An example device includes a lithium-based battery having conductive battery contacts protruding from a surface of the battery, where a non-conductive portion of the surface of the battery separates the conductive battery contacts. The battery is a type that undergoes an expansion during charging in which the expansion of the lithium-based battery includes an outward bulging of the non-conductive portion of the battery surface. The device includes a substrate having conductive substrate contacts. The conductive battery contacts are electrically connected to the respective conductive substrate contact via a flexible electrically-conductive adhesive that physically separates the conductive battery contacts from the respective conductive substrate contacts and allows for relative movement therebetween caused by the expansion of the lithium-based battery.

  • Patent number: 10873066
    Abstract: The present disclosure relates to a vent for a secondary battery top cover, a top cover assembly, a secondary battery and a vehicle. The vent includes a flat base and a protrusion protruding outward with respect to flat base. The protrusion has a main nick and at least one branch nick connected to at least one end of the main nick. An angle formed between the main nick and the branch nick is more than zero. When the pressure inside the case increases excessively, gas causes stress concentration at the protrusion such that the vent is torn along the main nick and the at least one branch nick, thereby releasing the gas in the case, reducing explosion risk of the secondary battery, and improving safety of the secondary battery.
