Lithium-Ion Secondary Battery Prototypes Components

We have been manufacturing lithium-ion secondary battery prototype components for over 20 years and have been working with at least two customers every month for the past five years. Despite often challenging some parts and processing techniques that are unprecedented in the world, we have an exceptionally high customer satisfaction rate.

Inquiry

Cases

Since expensive drawing dies are not used, initial costs can be reduced. It is ideal for the prototyping stage because it can accommodate minor dimensional changes.

The mold manufacturing process can be shortened, and products can be delivered to customers quickly.

The large degree of freedom in shape can be applied to aluminum, steel, stainless steel, titanium, and other materials that are difficult to press process.

Lid Assembly

We manufacture and deliver parts such as lid plates, terminals, packing, and current collectors in an assembled state, eliminating the need to communicate with each processing company.

We can also make proposals from the design stage. All parts are shipped after helium leak testing to ensure quality.

Manufacturing Components for Prototype Testing of Battery Cells

We manufacture various components our customers require for testing prototype battery cells. For example, we have much experience welding sensor mounting ports onto cell cases and lids and producing the jigs and equipment required for safety testing. We can also perform pressure resistance testing of cell cases.
