A lithium-ion battery module includes a housing having a plurality of partitions configured to define a plurality of compartments within a housing. The battery module also includes a lithium-ion cell element provided in each of the compartments of the housing. The battery module further includes a cover coupled to the housing and configured to route electrolyte into each of the compartments. The cover is also configured to seal the compartments of the housing.

A bipolar storage battery is described in which, even when growth occurs in a positive electrode due to corrosion caused by sulfuric acid contained in an electrolytic solution, the electrolytic solution has difficulty penetrating an interface between the positive electrode and an adhesive and battery performance is hard to decrease. The bipolar storage battery includes a bipolar electrode including a positive electrode, a negative electrode, and a bipolar plate in which the positive electrode is provided on one surface and the negative electrode is provided on the other surface. The bipolar electrode includes a covering member configured to cover a peripheral part of an opposite surface of the positive electrode in close contact with the peripheral part, the opposite surface being opposite to a surface, of the positive electrode, bonded to the bipolar plate.

In a battery casing a metal negative electrode that contains metal serving as a negative electrode active material and an air electrode are arranged so as to face each other in a state where at least a part of the metal negative electrode and the air electrode is immersed in an electrolytic solution inside a casing. The metal negative electrode is housed in a negative electrode housing in the casing. A separator separating the metal negative electrode and the air electrode is arranged at a side surface of the negative electrode housing. An opening through which inside of the negative electrode housing and outside of the negative electrode housing communicate with each other is provided on an upper surface of the negative electrode housing.

Various embodiments described herein relate to a battery that includes a battery cap with one or more cut-out sections. The battery cap may be used to at least partially cover a circuit board that is proximate an end of a battery cell. In various examples, the cut-out sections may be configured to accommodate one or more cell tabs of the battery that protrude above the circuit board.

This application relates to a separator with an organic-inorganic hybrid layer. By comprehensively adjusting an adaptive collocation relationship between the median diameter of the first inorganic particles and the median diameter of the second inorganic particles, and by controlling reasonable collocation between the microscale particles and the nanoscale particles, this application develops a separator that is capable of significantly reducing transition metal ions in an electrolytic solution and that is highly ion-permeable, thereby significantly improving the cycle performance and storage performance of lithium-ion batteries.
