The current production efficiency and yield of large cylindrical batteries are still relatively low, and there are still the following process difficulties in achieving high-efficiency mass production: 1) Full-tab forming: The difficulty lies in controlling the flattening accuracy and strength to avoid damage to the current collector or the generation of debris, dust, etc. 2) Collector plate and p...

Lithium iron phosphate (LiFePO4) cathode electrode material oil-based slurry usually uses N-methylpyrrolidone (NMP), dimethyl sulfoxide and dimethylformamide as solvents, which have problems such as difficult solvent recovery, large amount of use and environmental pollution. LiFePO4 positive electrode material water-based slurry uses deionized water as solvent, which is environmentally friendly an...

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...
