NMP is used in the positive electrode compounding slurry. The construction is added in two times: the first time is added according to the amount of PVDF, and the second time is added according to the slurry viscosity value to adjust the slurry viscosity

NMP is irritating to skin , eyes. In case of contact,affected area should be washed with plenty of water. If sticky, use waterless cleaner. Inhalation should be avoided. In event, victim should be moved to fresh air . Give oxygen or artificial respiration as needed. Obtain emergency medical attention . Prompt action is essential.
