Problems solved by technology

[0010] The above-mentioned Japanese Patent Publication No. 2007-323952 can connect the battery cells in series or in parallel, but it is also a process of bonding by welding. When the bonding force is reduced by external force, there is a problem that the entire power supply connection is released.
[0011] In addition, there is a problem that productivity decreases as the number of bonding processes equal to the number of laminated battery cells increases accordingly.

Abstract

Provided are a battery cell, a manufacturing method thereof, and a battery module including the same. According to the present invention, first and second electrode taps are formed at both sides of a case so as to be closely adhered thereto, respectively, such that the battery cell may be easily manufactured and the battery module may be easily formed by stacking.

Description

technical field [0001] The invention relates to a battery unit, its manufacturing method and a battery module including the battery unit. Background technique [0002] Generally, secondary batteries can be recharged and can be increased in capacity. Typical secondary batteries include nickel-cadmium, nickel-metal hydride, and lithium-ion batteries. Among them, the lithium-ion battery has attracted attention as a new generation power source due to its excellent characteristics such as long life and high capacity. Among them, the operating voltage of the lithium secondary battery is above 3.6V, which is used as a power source for portable electronic devices, or a plurality of lithium secondary batteries are connected in series for high-power hybrid vehicles, and nickel-cadmium batteries or nickel- Compared with metal hydride batteries, their operating voltage is three times higher, and their energy density characteristics per unit weight are also excellent, so their usage ten...
