The accelerating shift towards clean energy, particularly in EVs and energy storage, has led to unprecedented demand for high-quality lithium-ion and emerging solid-state batteries. Manufacturers face significant challenges in scaling production to meet this demand, often with limited resources, technical expertise, or market entry credibility.
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 .
In order to serve the rapidly growing electromobility market, particularly efficient manufacturing processes are required when it comes to the production of lithium-ion battery systems.
The lithium battery production process involves operations from nano-scale material processing to meter-scale device production and processing. In the past, lithium battery production primarily focused on improving equipment manufacturing efficiency, quality, and cost based on Newtonian mechanics.
