Thin-film batteries having a novel encapsulation system.

Thin-film batteries having a novel encapsulation system.

A housing part for an electrical device, which is an electrical storage device, a sensor housing, a battery, a microbattery, or a capacitor, the housing part including: a feedthrough, the housing part or a base body which is a part of the housing part including the feedthrough, the feedthrough having at least one opening, the at least one opening having a wall with a reduced enclosure length EL.sub.red, the at least one opening configured for receiving a conductive material or a conductor in a glass material or a glass-ceramic material, the reduced enclosure length EL.sub.red being in a range of 0.05 mm to 0.6 mm, 0.1 mm to 0.5 mm, 0.1 mm to 0.4 mm, or 0.15 mm to 0.2 mm.

The terminal component disclosed herein is a terminal component for use in a terminal for secondary batteries. The terminal component includes a first metal and a second metal having a recess. The first metal includes a shall having a pair of flat surfaces and a fitting portion formed at one end of the shaft in the major axis direction. At the boundary between the first metal and the second metal, a joining portion joined by ultrasonic, joining and a crimping portion where the fitting portion of the first metal is fitted into the recess of the second metal are formed. A gap is formed between the recess and the fitting portion in the facing direction in which the gap faces the flat surfaces in plan view.

Provided is a secondary battery. The secondary battery includes a can, an electrode assembly in the can, a collector plate electrically connected to the electrode assembly, and a terminal having a coupling part mechanically coupled to the collector plate by a pressure, electrically connected to the collector plate, and electrically connected to the electrode assembly.

The present application relates to the technical field of lithium batteries. Disclosed is a lateral-weld soft connector having a pole column. The connector comprises a first connector, which a top end face configured to face upward; a pole column which extends upwards protrudes out of the top end face of the first connector; a second connected extending outwards and connected to a cell is provided at one side of the first connector; the second connector is bent downwards with respect to the first connector and is disposed at a side edge of the cell.

A battery terminal bushing is disclosed. The battery terminal bushing comprises a body having an insertion end and an exterior end opposite the insertion end. One or more sealing rings surround the body between the insertion end and the exterior end. A terminal post connector segment is provided on the insertion end of the body. An anti-torque pattern is provided on one or more surfaces of the body configured to engage and be contained within the battery housing material. A lead acid battery comprising the battery terminal bushing is also disclosed.

A battery (100) and a battery pack having the same, and an electric vehicle are disclosed. The battery (100) includes: a housing; a cover plate (30) located at an end of the housing; a terminal (40) disposed on the cover plate (30); a pole core (10) located inside the housing and having a tab (20), at least one part of the tab (20) being connected to the terminal (40); and an insulating spacer (50) covering one side that is of the at least one part of the tab (20) and that faces away from the terminal (40).

Provided is a battery module. The battery module includes: a plurality of battery cells each including an electrode terminal; and a bus bar connected to the electrode terminals of the battery cells neighboring each other to electrically connect the battery cells, the bus bar including a first bus bar and a second bus bar that are superposed on each other and include different metals, each of the first and second bus bars making conductive contact with the electrode terminals. Therefore, the thermal and electrical characteristics of the bus bar electrically connecting the neighboring battery cells to each other may be improved while improving weldability between the bus bar and electrode terminals.
