    Abstract: Techniques effectively prevent an overcurrent from occurring in a system comprising assembled batteries connected in parallel to a power supply line, when a given assembled battery is connected to the power supply line. Multiple battery units are each configured such that they can be connected to a power supply line. Each battery unit includes a battery cell group configured including multiple battery cells, a switching unit arranged between the power supply line and the battery cell group so as to control a current that flows between the power supply line and the battery cell group, and a control unit that controls the switching unit.

    Abstract: The present invention provides a non-aqueous electrolyte secondary battery that can suppress a drop in a flash point of an electrolyte solution even if the non-aqueous electrolyte secondary battery is used for a long time. The non-aqueous electrolyte secondary battery includes: an electrode body having a structure in which a positive electrode including a positive-electrode active material and a negative electrode including a negative-electrode active material are stacked with a separator interposed therebetween; a non-aqueous electrolyte solution containing a flame retardant; and an outer casing accommodating the electrode body and the non-aqueous electrolyte solution. The non-aqueous electrolyte solution in the electrode body has a flame retardant concentration lower than a flame retardant concentration in the non-aqueous electrolyte solution between the electrode body and the outer casing.

    Abstract: A method of the present invention for manufacturing a lithium-ion cell comprises the step of impregnating a porous positive-electrode active material layer or a porous negative-electrode active material layer with an ionic liquid electrolyte. The ionic liquid electrolyte includes: an ionic liquid comprising an anion and a cation; and a lithium salt dissolved in the ionic liquid. The anion is bis(fluorosulfonyl)imide ion. The lithium salt is lithium bis(fluorosulfonyl)imide or lithium bis(trifluoromethansulfonyl)imide. The ionic liquid electrolyte contains the lithium salt at a concentration of 1.6 mol/L to 3.2 mol/L inclusive. The step of impregnation with the ionic liquid electrolyte is the step of impregnating the positive-electrode active material layer or the negative-electrode active material layer with the ionic liquid electrolyte at a temperature of 50° C. to 100° C. inclusive.

    Abstract: The occurrence of separation or reaggregation is suppressed in a suspension such as a battery electrode slurry. A battery electrode slurry distributing apparatus includes: a circulation pipe via which a positive electrode slurry is to be circulated; and a control unit that controls the supply of the positive electrode slurry to each of coaters. In a period in which either the coater is allowed to receive the supply of the positive electrode slurry, the control unit inhibits the supply of the positive electrode slurry to the other coater. The circulation pipe is structured in a polygonal loop. The coaters are connected to respective elbow portions formed in the circulation pipe via the pipes, respectively.
