1. Requests and development requirements
First, we will ask you about your problems related to batteries and what you would like to achieve. ENAX will then define the specific battery development requirements to realize your product.
2. Material Search
Lithium-ion batteries use various materials such as positive (negative) electrode materials, conductive materials, electrolyte, and separators. We search for and select the most suitable materials according to development requirements.
3. Element Development
Element development is a phase in which the electrode recipe and electrolyte recipe are examined and then checked to see if they match the characteristics of the product according to development requirements. This is done in a single layer pouch cell, which is the smallest unit of a lithium-ion battery.
4. Functional verification
Verification is carried out in stacked cells that are close to the actual size for product mounting. For example, this phase evaluates the resistance, heat generation, durability, reliability, etc. when the input/output current required for the product is applied.
5. Verification of actual equipment installation
This is the phase in which we procure the necessary amount of dedicated materials based on the number of cells required for product mounting, and manufacture prototype cells in facilities and processes that are close to those used for mass production. In this phase, we verify whether the performance of the cells is as expected for use in the final product, and conduct tests to ensure compliance with regulations. This is also the phase to determine if the performance and quality are confirmed and can be transferred to small-scale production.
6. Small-scale production of products mounted on actual equipment
This is the phase that prepares for the transfer to mass production process. This phase mainly includes adjustment of manufacturing processes and lines using assembly facilities based on the assumption of mass production volume, adjustment of inspection contents and inspection processes to ensure mass production quality, and preparation of procedures, PL, QC, etc. for manufacturing.
7. Mass production transfer
The final phase is the transfer to mass production. Depending on the volume of mass production, ENAX not only handles mass production, but can also transfer production to a customer-designated manufacturing site.
