Abstract:
A battery of the invention includes: a machine part (20) having an opening opened from at least one edge thereof and a cover (21) having an outer diameter larger than the diameter of the opening and covering the opening. The cover (21) is fitted to the outside of the casing body (20) by an outside-fitting, and the edge of the cover (21) and the casing body (20) are welded to each other to form a battery case (10). Because the cover (21) is fitted and welded to the outside of the casing body (20), the cover (21) does not fall into the casing body (20), and metal melted during the welding of the cover does not flow into the inside of the casing body (20).
Abstract:
An electrochemical storage cell having a coiled core is disclosed. The coiled core includes a cathode sheet, an anode sheet, and a separator sheet. An anode connector is connected with the anode sheet at a first end of the coiled core and a cathode connector is connected with the cathode sheet at a second, opposite end of the coiled core. The coiled core has a length Lcore and a width Wcore and each connector has a width Wconnector. The length of the coiled core Lcore, width of the coiled core Wcore, and width of each connector Wconnector have the relationship 0
Abstract:
In a vehicular power supply system, inclined portions (16c) extending obliquely upward toward the exterior from two mutually opposing side edges of a waterproof case (14) are formed on a hanger frame (16), and an upper face opening (14b) of the waterproof case (14) and an outer peripheral part of a lid member (15) are equipped with extended portions (14a, 15a) extending upward so as to cover the inclined portion (16c) of the hanger frame (16). This enables water flowing on an upper face of the lid member (15) or water that has accumulated on the upper face of the lid member (15) to be blocked by the extended portions (14a, 15a) and to be prevented from entering the interior of the waterproof case (14) via an outer peripheral face of the hanger frame (16) running through mating faces of a lid member (15) and the waterproof case (14) housing a battery module (24) and a high voltage electrical component (33).
Abstract:
A rechargeable battery including an electrode assembly; a case housing the electrode assembly; a cap assembly including a cap plate having a short-circuit hole and sealing an opening of the case; and a short-circuiting member including a short-circuiting plate arranged at the short-circuit hole and a connection plate covering at least a portion of the short-circuit hole at an exterior side, the connection plate being spaced apart from the cap plate and electrically connected to the electrode assembly, and the case and the cap assembly are electrically insulated from the electrode assembly.
Abstract:
A rechargeable battery includes an electrode assembly having electrodes on opposite sides of a separator, a case retaining the electrode assembly, a cap plate coupled with an opening of the case, electrode terminals extending through terminal holes of the cap plate, lead tabs connecting the electrode terminals to the electrode assembly, the electrode terminals being electrically connected to the lead tabs at connection parts, and insulators, the connection parts being embedded in the insulators.
Abstract:
The present invention provides a battery that includes: a lid plate provided with a terminal pull-out through hole and a baffling portion whose upper surface is configured in a projecting and/or recessed manner; an auxiliary terminal configured such that a lower portion thereof is connected to a metallic foil of a power generating element by being fitted into a battery container through the terminal pull-out through hole, and sealed and fixed to the lid plate by insulating and sealing members; a connecting conductor connected and fixed to an upper portion of the auxiliary terminal; and an external terminal having a bolt portion that projects upward from a base portion, the bolt portion being inserted through the terminal through hole of the connecting conductor from below, and the base portion being engaged with the baffling portion of the lid plate, thereby restricting rotation centering an axial line of the bolt portion.
Abstract:
A cover for a battery module having a plurality of battery cells arranged in a stacked configuration includes a non-conductive main body having a plurality of spaced apart recessed regions formed therein and a plurality of electrically conductive connectors, each of the connectors disposed in one of the recessed regions and coupled to the main body.
Abstract:
Provided is a battery case cover which can be produced through a single process, by integrally forming the structural components of a battery case cover such as a recovering part, a cell partition part and a gas inlet part on the bottom surface, while forming the recovering part in the shape of a pipe and applying a vent cap mode to the gas inlet part.
Abstract:
A battery is provided, comprising: a battery housing having at least one opening end; a battery cover sealing the at least one opening end; an electric core received in the battery housing, which comprises at least one heat-conducting tube having at least an end penetrating through the battery cover; and an electrolyte filled in a space formed by the battery housing with the battery cover.
Abstract:
A battery includes current collectors for electrically connecting a power generating element contained inside of a battery case to external terminals, respectively. A caulking head of a rivet for fixing the negative current collector to a cover is contained in a engagement recess which is a space inside of a engagement receiving portion in the cover. The positive current collector is caulked to the cover via a shaft of the positive external terminal. A caulking head at a tip end of the shaft is contained in the engagement recess which is a space defined inside of the engagement receiving portion. The caulking heads do not project from a lower surface of the cover, and therefore, a clearance space defined between the power generating element and the cover is set to the minimum.
