Why are lithium-ion batteries becoming more popular?

With the rapid development of new energy vehicles and electrochemical energy storage, the demand for lithium-ion batteries has witnessed a significant surge. The expansion of the battery manufacturing scale necessitates an increased focus on manufacturing quality and efficiency.

What are the manufacturing data of lithium-ion batteries?

The manufacturing data of lithium-ion batteries comprises the process parameters for each manufacturing step, the detection data collected at various stages of production, and the performance parameters of the battery [25, 26].

How to improve the production technology of lithium ion batteries?

However, there are still key obstacles that must be overcome in order to further improve the production technology of LIBs, such as reducing production energy consumption and the cost of raw materials, improving energy density, and increasing the lifespan of batteries .

Should new battery manufacturing technologies be transferable to beyond Lib manufacturing?

Therefore, when evaluating the new manufacturing technologies, transferability to beyond LIB manufacturing should be considered. Although the invention of new battery materials leads to a significant decrease in the battery cost, the US DOE ultimate target of $80/kWh is still a challenge (U.S. Department Of Energy, 2020).

Why do we need new production technologies compared to conventional lithium-ion cells?

Therefore, new production technologies will be necessary in comparison to the conventional production of lithium-ion cells [183, 184]. High power density, high energy density, safety, low cost, and long life time are all essential characteristics of ASSBs, particularly when applied to electric vehicle applications .

What is the manufacturing process of lithium-ion batteries?

Fig. 1 shows the current mainstream manufacturing process of lithium-ion batteries, including three main parts: electrode manufacturing, cell assembly, and cell finishing .
