    摘要: A lithium secondary battery includes an electrode assembly including a cathode and an anode facing the cathode, a case accommodating the electrode assembly, an electrolyte accommodated in the case together with the electrode assembly, and an electrolyte storage unit inserted into the case to supply a supplementary replenishment. The electrolyte storage unit includes a first unit including a first body having a tubular structure and first holes formed through the first body, and a sub-unit including a tubular body and sub-holes formed through the tubular body. The sub-unit is inserted into the first unit so that the sub-holes are offset from the first holes.

    摘要: A battery and an electric device are provided. The battery includes a first box portion, a second box portion, a battery cell, and an insulating liquid. The first box portion and the second box portion fit together to define an accommodating space. The battery cell is accommodated in the accommodating space. The battery cell is provided with an electrode terminal and a pressure relief mechanism. The electrode terminal is closer to the first box portion relative to the pressure relief mechanism. The pressure relief mechanism is configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to release the internal pressure or high-temperature gas. The insulating liquid is provided in the accommodating space and immerses the pressure relief mechanism. When the insulating liquid is provided in the accommodating space, the first box portion is located above the second box portion.

    摘要: Systems, apparatuses, and/or the like are provided. In some embodiments, an electrochemical cell includes a container; a first electrode disposed within the container. In some embodiments, the first electrode includes a first electrode portion; and a second electrode portion conductively connected with the first electrode portion and spaced apart from the first electrode portion to define at least one reservoir between the first electrode portion and the second electrode portion. The at least one reservoir is bounded at least in part by a first reservoir wall of the first electrode portion and a second reservoir wall of the second electrode portion. A second electrode may be disposed within the container, and a separator is disposed between the first electrode and the second electrode. In some embodiments, the cell includes an electrolyte solution permeating the first electrode and the second electrode and at least partially filing the at least one reservoir.
