- the present invention relates to a laser notching device, and more specifically, to a laser notching device for notching electrode tabs on an electrode sheet.
- types of secondary batteries include nickel cadmium batteries, nickel hydrogen batteries, lithium ion batteries, and lithium ion polymer batteries. These secondary batteries are used not only for small products such as digital cameras, P-DVDs, MP3Ps, mobile phones, PDAs, Portable Game Devices, Power Tools, and E-bikes, but also for large products requiring high output such as electric vehicles and hybrid vehicles, as well as for surplus power generation. It is also applied and used in power storage devices that store power or renewable energy and backup power storage devices.
- Secondary batteries are classified into pouch type and can type, etc., depending on the material of the case that accommodates the electrode assembly.
- the can type is manufactured by housing the electrode assembly in a hard can, and a secondary battery with a cylindrical can can be called a cylindrical secondary battery.
- can-type secondary batteries especially cylindrical secondary batteries
