The production process of a lithium-ion battery cell consists of three critical stages: electrode manufacturing, cell assembly, and cell finishing. The first stage is electrode manufacturing, which involves mixing, coating, calendering, slitting, and electrode making processes.
Developments in different battery chemistries and cell formats play a vital role in the final performance of the batteries found in the market. However, battery manufacturing process steps and their product quality are also important parameters affecting the final products’ operational lifetime and durability.
Since battery production is a cost-intensive (material and energy costs) process, these standards will help to save time and money. Battery manufacturing consists of many process steps and the development takes several years, beginning with the concept phase and the technical feasibility, through the sampling phases until SOP.
The second stage is cell assembly, where the separator is inserted, and the battery structure is connected to terminals or cell tabs. The third stage is cell finishing, involving the formation process, aging, and testing. Here is an overview of the production stages:
Knowing that material selection plays a critical role in achieving the ultimate performance, battery cell manufacturing is also a key feature to maintain and even improve the performance during upscaled manufacturing. Hence, battery manufacturing technology is evolving in parallel to the market demand.
The development of new battery technologies starts with the lab scale where material compositions and properties are investigated. In pilot lines, batteries are usually produced semi-automatically, and studies of design and process parameters are carried out. The findings from this are the basis for industrial series production.
How Electric Car Batteries Are Made: From Mining To Driving
Materials Within A Battery Cell. In general, a battery cell is made up of an anode, cathode, separator and electrolyte which are packaged into an aluminium case.. The positive anode tends to be made up of graphite which is then coated in copper foil giving the distinctive reddish-brown color.. The negative cathode has sometimes used aluminium in the …
