Formation, Ageing and Testing of Cells

Understand the importance and functionality of the cell formation

Initial and subsequent charging and discharging cycles. Mechanism of interphase layers formation (solid electrolyte and cathode electrolyte interphases). Importance of the rest and stabilisation. Influence of formation cycles on the cell performance.

Know and understand the cell ageing procedure

Specifics of the elevated temperature ageing to complete formation. Mechanism of interphase layer stabilisation and Li-ion concentration balancing. Influence of time and temperature of the ageing process on the cell performance.

Know and understand the testing procedures to evaluate cell properties

Testing and evaluation of the manufactured cell capacity, impedance and voltage. Expected load testing and thermal characterisation. Visual inspection of damage, leaks and other possible defects. Ability to operate the typical testing equipment.

Know the final cell testing documentation and procedures

Ability to evaluate and classify overall performance of each cell and create Battery Summary Test documentation prior to dispatch. End-of-line (EOL) testing to ensure all performance criteria are met.

Formation technicians perform formation, ageing and testing processes and final inspection of cells, ensuring cells are charged and working.

This intensive one-day course is designed to provide an in-depth, overview focussing specifically on the process of Formation, Ageing and Testing within battery manufacture. Attendees will cover the processes of Cell Assembly and be able to see these processes used on gigafactory scale equipment in our Industrial scale-up Line.
