Cylindrical Li-ion Battery Structure

Thinpack cylindrical Li-ion batteries are classified into three components – jellyroll, current connectors, and safety devices. The three data system batteries have each various benefits.

  1. Jellyroll – It is made up of positive and negative electrodes that are rolled together. Jellyroll is then used to construct the electrochemical cell into a battery casing.
  2. Current Connectors – It is used to send electrons from one device to another. The four current connectors include positive terminal, negative terminal, positive terminal lead, and negative terminal lead.
  3. Safety Devices – Insulation plates, case, gasket, anti-explosive valve, positive element, and exhaust gas hole are built into the structure to ensure safe battery operation.

How We Manufacture Cylindrical Li-Ion Battery

First, we prepare the electrode sheet

Second, the assembly of the Li-ion cell

Third, we proceed with the formation and sealing of the battery case

Then last but not least, we test the battery.

We utilize a device to measure the performance of newly produced batteries. And another tester to determine the internal resistance of the unit.
