NOVELTY - Method for preparing porous electrode using anti-gel positive electrode slurry, involves mixing and stirring positive electrode active material, conductive agent and binder, where the positive electrode active material is one of lithium iron phosphate, lithium cobaltate, lithium manganate and ternary materials, adding portion of organic solvent to the mixed material and stirring, where the solid content of the slurry is 70-75 wt.%, adding pore-forming agent and remaining organic solvent, stirring and dispersing, where the solid content of the slurry is 62-70 wt.% at this time, increasing stirring and dispersing speed, reversely rotating and removing bubbles, pouring the slurry into buffer tank and slowly stirring for coating, and coating the slurry on an aluminum foil and baking at 90-150℃ and cooling. USE - Method for preparing porous electrode using anti-gel positive electrode slurry. ADVANTAGE - The positive electrode slurry helps to increase liquid retention of electrode sheet, improve rate performance of battery cell, and reduce polarization of the electrode sheet. The pore-forming agent can be miscible with N-methylpyrrolidone to ensure uniform dispersion of the pore-forming agent in the slurry. The method is capable of controlling drying temperature of the electrode piece, controlling volatilization speed of glycolic acid and acetic acid and decomposition speed of anhydrous oxalic acid and anhydrous citric acid, and improving porosity of the electrode piece to ensure that the structure of the electrode piece is not damaged.
