Lithium-ion batteries (LIBs) are the powerhouse of modern electronics and electric vehicles (EVs), and their performance hinges on the cathode materials. Among these, ternary cathode materials such as NCM (Nickel-Cobalt-Manganese oxides) and NCA (Nickel-Cobalt-Aluminum oxides) dominate due to their balanced energy density and stability. However, varying the ratios of nickel (Ni), cobalt (Co), mang...read more

Solid-State Battery Production ProcessJan 21 , 2025Solid-state batteries and liquid batteries have many similarities in manufacturing processes. For example, the manufacturing process of electrode sheet is based on slurry mixing, coating and calendering. After slitting, the tabs are welded and PACK (battery packs are processed into groups). However, there are also some differences. There are three core differences: 1) Composite cathode materials f...read more
