Abstract: A battery pack case which is used for forming a battery pack that is mounted at an electric vehicle, the battery pack case comprising: a tray that is attached to a body of an electric vehicle; a battery-holding member for holding a battery, the battery-holding member being attached onto at least a part of the tray; and a cover that covers the tray and the battery-holding member from above, wherein at least two of the tray, the battery-holding member, or the cover contain a fiber-reinforced plastic.

Abstract: A non-aqueous electrolyte solution for a battery contains a phosphazene compound (A) that contains at least one of a phosphazene compound represented by Formula (1) or a phosphazene compound represented by Formula (2). In Formulae (1) and (2), each of Y? and Z? independently represents an anion in which a proton is removed from an inorganic acid or an active hydrogen compound; each of twenty-four Rs independently represents a hydrocarbon group having from 1 to 10 carbon atoms; and, among the twenty-four Rs, two Rs bonded to the same nitrogen atom are optionally bonded to each other.

Abstract: It is an object of one or more embodiments of the present disclosure to provide a battery charger with a constant current control loop, for use in linear and switching chargers. Advantages include digital controls and a comparator, for decreasing charging current towards termination. The technique of the disclosure eliminates a constant voltage loop and amplifier, without increasing charging time. The technique also simplifies porting the design to another process technology node, and reduces size.

Abstract: A self-extinguishable film for a lithium-ion battery, comprising a self-extinguishing layer containing a heat-meltable binder and fire extinguishing agent particles.

Abstract: A lithium-ion battery stack that is a layered body includes: a plurality of lithium-ion batteries layered directly or with other layers therebetween; and one or more self-extinguishing layers.

Abstract: Provided are an outer packaging film for a lithium-ion battery, a lithium-ion battery, and a lithium-ion battery stack. The outer packaging film for a lithium-ion battery has a layered structure that includes a thermal adhesive layer, a metal layer, and a gas barrier layer, wherein the thermal adhesive layer, the metal layer, and the gas barrier layer are arranged in this order, and wherein the layered structure further includes a self-extinguishing layer.
