Method and system for detecting welding quality of battery by using vibration signal

Номер: CN116413199A
Автор: LYU XIAWU, SOHN WON-JUN
Принадлежит:

The invention provides a method and a system for detecting the welding quality of a battery by using a vibration signal, and the method comprises the steps: applying a first vibration signal to a first welding workpiece of a to-be-detected welding part in the battery; vibration parameters of a first detection position (namely a detection position) on a first welding workpiece and a second detection position (namely a reference detection position) on a second welding workpiece are detected respectively; the difference value of the first vibration parameter and the second vibration parameter corresponding to the detection position and the reference detection position is compared with the parameter range determined by the well-welded welding part so as to determine the welding quality of the to-be-detected welding part, the vibration condition (vibration parameter) of the reference detection position is deducted, and the welding quality of the to-be-detected welding part is determined. Therefore ...

The invention belongs to the technical field of agricultural product waste treatment and secondary utilization, solid waste treatment and novel grouting material research and development, and particularly discloses a modified rice hull fiber toughened grouting material and a preparation method thereof.The modified rice hull fiber toughened grouting material is formed by mixing a solution A and a solution B. The volume ratio of the solution A to the solution B is 1: 0.53-1: 0.76. The solution A is prepared from, by weight, 400 parts of cement, 5-20 parts of modified rice hull fibers, 20-30 parts of water, 20-30 parts of water, 20-30 parts of water, 20-30 parts of water and 20-30 parts of water. 5-10 parts of a silane coupling agent, 10-20 parts of an early strength agent and 300 parts of water; the liquid B is prepared from the following components in parts by weight: 150 parts of sodium silicate, 320 parts of fly ash and 300 parts of water. Compared with the prior art, the prepared modified ...

Soft package buckle type battery cell

Номер: CN115986277A
Автор: LYU XIAWU, SOHN WON-JUN
Принадлежит:

The invention belongs to the technical field of batteries, and particularly relates to a soft package buckle type battery cell which comprises a battery cell body, a first tab, a second tab and a shell, the shell is provided with a containing groove and a skirt edge, the battery cell body is contained in the containing groove, and the first tab and the second tab are both connected with the battery cell body. The outer end of the first tab and the outer end of the second tab penetrate through the skirt edge, a plurality of notches are formed in the skirt edge, and the notches are distributed on the two sides of the first tab and the second tab. Notches are punched in the two sides of the tab, the non-tab position is embossed, and due to the fact that the tab position is not embossed in the scheme, the risk that the tab position is damaged or the tab is broken due to the fact that the tab is crushed in the embossing process can be reduced; meanwhile, according to the scheme, the folded skirt ...
