Battery manufacturing is composed of electrode, assembly and formation processes. In the Electrode process, raw materials are mixed and coated on to foils to make electrode sheets. Then, electrode components are stacked, welded and packaged in a cell housing during the Assembly process. Finally, through the Formation process the assembled cell is activated with electric energy and tested to evaluate its performance and characteristics. Battery process engineer is responsible for work that includes but not limited to monitoring, analyzing, and reporting of production results, and ensuring high yield and productivity for each electrode, cell assembly and formation process by implementing and improving manufacturing methods and processes. This position will also need to interact with other teams and vendors to solve complex and/or urgent problems by identifying and evaluating alternatives or by providing needed information and advice. As working on a 24/7 facility, this position may require on-call support in various circumstances. Candidates should be motivated problem solvers that can provide creative solution approaches to your task with concern about effectiveness and quality that are well based in the technology expertise and best practices. Electrode Mixing: The active materials are mixed by combining the processed metal oxides with a conductive additive and a binder Coating: This mixture is called a slurry which is then coated onto metal foil sheets, typically aluminum or copper Pressing: To press the coated electrode materials. Pressing removes excess solvents and improves the density, adhesion Slitting: The machine uses sharp blades or rotary cutters to slice the sheet into narrower strips or ribbons of the desired width Assembly Notching: Refers to the process where reel of electrode is cut into individual sheets with designed dimensions Vacuum Drying: Vacuum drying removes moisture from sheets of electrodes to ensure low moisture content in assembled battery cells Stacking: The cathode and anode foils are stacked together with a separator material in between to create a jelly roll-like structure. Tab welding: Tab welding connects a set electrode foils to tab. Packaging: The purpose of packaging is to place Jelly roll into formed pouch, fill with electrolyte and seal Formation Pre-Charging: It is the initial charging process performed on a newly assembled battery pack. Degassing: It is a critical step that helps remove any excess or volatile gasses that may have accumulated within the battery cells. Aging: A controlled procedure where the battery cells are subjected to specific conditions to simulate their performance over time. Inspection: In inspection the battery cells undergo final testing to ensure they meet the required performance and quality standards.
