Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).
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.
Challenges in Industrial Battery Cell Manufacturing The basis for reducing scrap and, thus, lowering costs is mastering the process of cell production. The process of electrode production, including mixing, coating and calendering, belongs to the discipline of process engineering.
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.

Recent developments: In August last year, US battery energy storage company Powin Energy signed a master supply agreement with EVE Energy that made the Chinese company a “strategic battery cell supplier for its [Powin's] 'Stack' products”.
Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group. The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC's MG4/Mulan, and various Li Auto models.
This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models. The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.
In February 2023, the company's dominant position in the electric vehicle (EV) battery market was cemented by a report from SNE Research—a South Korean firm, which highlighted Contemporary Amperex Technology Limited's (CATL's) growth to 191.6 GWh produced in 2022.

In the context of rapidly increasing production scrap in LIB production, it was shown that a solvent-based mechanical recycling process is an efficient way to directly recycle both the anode and cathode coating materials and return the resulting suspension directly to the electrode manufacturing process.
Production of battery manufacturing scraps in a closed loop from production to recycling of LIBs. As the main source of battery scraps, efforts are being made to improve and optimize the manufacturing processes.
As such, the production scrap, containing valuable metals such as cobalt, nickel, lithium and manganese, will either be lost completely and never used in batteries, or be imported to Europe in the form of new batteries, creating an unfair competitive advantage for non-EU recyclers, materials producers and battery manufacturers.
Advancement in battery manufacturing technologies is crucial for decreasing the production rate of battery manufacturing scraps. Firstly, every step in the battery cell production process should be optimized to minimize the rejection rate.
Li-Cycle, a Canadian LIB recycling company, estimates that the share of manufacturing scrap in their waste sources will be 68 % in 2025 . According to the report from CES [7, 8], the amount of battery manufacturing scraps will keep increasing until 2030 as battery production continues to grow.
The primary challenges for battery scraps relate to the kinds of recycling technologies. Present recycling methods still pose significant limitations to the efficient recycling process. Despite advancements in direct recycling methods, these methods are often limited to lab scales.
According to the report from CES [7, 8], the amount of battery manufacturing scraps will keep increasing until 2030 as battery production continues to grow. As shown in Fig. 2 (c), CES estimates that approximately 0.982 Mtons of battery manufacturing scraps will be generated globally in 2030 .
