The present disclosure relates to an anode for a lithium secondary battery, wherein an anode material layer is formed on at least one surface of an anode current collector, and

Anode including graphite and silicon-based material having different diameters and lithium secondary battery including the same

A secondary battery includes an electrode assembly, and a battery case accommodating the battery case together with an electrolytic solution. The battery case includes a metal. The battery case is opened in its upper part; and a cap assembly that is coupled to the opened upper part of the can body. The can body includes a beading part that is bent inward at the upper part of the housing part, and a crimping part that is bent in a direction in which the cap assembly is located at an upper part of the beading part. At least one of the bottom part or the crimping part of the can body has a metal member inserted therein. The metal member has a lower melting point than the metal of the can body.

Secondary battery in which a metal member is inserted into can body to improve safety

The present technology relates to an electrode slurry coating method and apparatus comprising a pressure adjustment member for adjusting the discharge pressure of slurry, and enables electrode slurry to be discharged under constant pressure even when a coated part and an uncoated part are repeatedly formed on a current collector layer.

Electrode slurry coating method and apparatus comprising pressure adjustment member

A cylindrical battery includes a metal can, an electrode assembly located in the metal can, a cap assembly containing a current interruptive device located on a top of the electrode assembly, an upper insulator located between the cap assembly and the electrode assembly, and at least one spring integrally connected to a lower surface of the current interruptive device.
