The electrode flattened in the pressing process is still a hundred(s) meters long. In the slitting phase, the battery electrode is cut to the right battery size. The two-phase process includes first cutting the electrode vertically (slitting) and then making a V-shaped notch and tabs to form positive and negative terminals (notching).
By understanding the chemical and structural changes that occur during battery degradation, recycling processes can be optimized to maximize the recovery of critical metals

The recent improvements in battery design are also related to the increasing market share of battery vehicles. When the Li-ion batteries were just prototypes for the early EVs, traditional and basic design approaches were employed in the battery design process. With the widespread use of Li-ion batteries for EVs, there was an early necessity to

The manufacturing process of lithium-ion batteries consists largely of 4 big steps of electrode manufacturing, cell assembly, formation and pack production, in that order. Each step employs highly advanced technologies. Here is an image that shows how batteries are produced at a glance. STEP 1. Electrode manufacturing – making the cathode and anode of a battery. ①
Albeit there is an environmental incentive, the economic viability of treating and recycling battery waste remains a two-pronged issue: first, the current salvaging infrastructure is mainly designed to process legacy technology and not recent trends of manufacture, limiting the recovery of materials to those present in large quantities (e.g., heavy metals) and excluding
For battery cell manufacturing, process models that describe the relationships of its process parameters and intermediate product properties (IPPs) can greatly facilitate cell design, process planning, and manufacturing optimization. However, due to the complexity of battery cell manufacturing, no battery manufacturing process model covering the entire

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.
The battery recycling process is generally divided into pretreatment and post-treatment stages. The pretreatment process involves removing the risk of explosion and crushing the batteries, while the post-treatment process involves recovering metals from the crushed batteries.
Battery manufacturers can also integrate their on-site recycling facilities tailored to their battery scraps since direct recycling is efficient and easy to operate. Such in-house recycling sites can also avoid the challenges and problems caused by transportation, further streamlining the recovery process.
Improving the separation and collection practices is essential to ensure the following recycling process is efficiently processed. Battery manufacturers can also integrate their on-site recycling facilities tailored to their battery scraps since direct recycling is efficient and easy to operate.
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.
Along with the transport distance, the transport quantities, capacity utilization, and additional safety precautions are important cost factors. Taking into account emissions trading and CO 2 prices, additional transport routes can have a great impact on the future profitability of battery production and recycling.
