Battery Testing Instruments

Electrolyte filling presents one of the key challenges in GIGA-scale, hardcase Li-ION cell production. As cell energy densities rise, achieving full electrode wetting becomes increasingly time-consuming and complex. In response, PEC has developed a unique, patent-pending Rapid Single-step Electrolyte Filling solution.

The core component of our system is the formation tower, essential for the electrical activation and testing of cells post-electrolyte filling. These towers perform charging and discharging cycles to develop a uniform SEI layer within the cells and assess key characteristics such as cell capacity, internal resistance, and peak performance.

After Pre-Charge, the cells will be finally degassed, cleaned and sealed for further processing. An endcap will be laser welded over the filling hole, providing a clean and reliable closure of the cell. The machine is also part of the Cell Finishing Line, using a micro-dry environment inside the machine. This way we avoid the complex logistics of moving pallets between the main dry room and formation area. PEC’s proprietary laser welding technology provides minimum energy to the weld pool, reducing the area affected by heat.

The equipment is positioned on both sides of an Automated Storage and Retrieval System (ASRS). The ASRS crane system will automatically transport the cells from one process step to the next until all process steps are finished and cells can be presented at the output conveyor.
