  • Patent number: 11367934
    Abstract: A secondary battery includes an electrode assembly including first and second electrodes, an outer body having an opening and housing the electrode assembly, a conductive sealing plate sealing the opening, and a deformable member. The sealing plate has a first through-hole. The deformable member seals the first through-hole. When the opening of the outer body faces upward, a second electrode connecting member electrically connected to the second electrode is above the deformable member. A conductive conducting member is disposed between the second electrode connecting member and the deformable member. The diameter of the conducting member is larger than the diameter of the first through-hole. When the pressure inside the outer body becomes equal to or higher than a predetermined value, the deformable member is deformed and brings the conducting member into contact with the second electrode connecting member and electrically connects the sealing plate and the second electrode connecting member.

  • Patent number: 11239498
    Abstract: The present disclosure relates to the technical field of lithium-ion battery, and particularly, to an electrolytic solution and a lithium-ion battery including the electrolytic solution. The electrolytic solution includes additives, and the additives include an additive A and an additive B. The additive A forms a film on the surface of the positive electrode and effectively prevents interface side reactions at the positive electrode. Comparing with the additive A, the additive B is preferentially reduced to form a film at the negative electrode, avoiding an increase in impedance and deterioration of cycling dynamic performance, etc., caused by film formation of the additive A on the negative electrode. The combination of the additive A and additive B imparts the battery with a reduced gas production, a higher capacity retention rate and a lower impedance at high temperature.
