Today, a batch of lithium battery grade NMP solvent is ready to be shipped to our customer's factory. NMP is a nitrogen heterocyclic compound with a series of excellent physical and chemical properties. It is non-toxic, high boiling point, strong polarity, low viscosity, low corrosiveness, high solubility, low volatility, good stability, and easy to recycle efficient and selective solvent. NMP is a very important auxiliary material for the production of lithium-ion battery electrodes. It is a solvent commonly used in the front-end batching process of lithium-ion batteries. It is commonly known as methyl and its molecular formula is C5H9NO. In the mixing stage: as a PVDF solvent, it participates in the dispersion of the slurry to form a uniform medium and maintains a stable slurry for a long time within a certain viscosity range In the coating stage: as the main liquid carrier of the slurry, it is uniformly coated on the metal substrate with a stable thickness, and it is required to have very good wettability and fluidity with the metal substrate In the baking stage of the coating process: the wet film runs at a uniform speed in the oven, the solvent volatilizes regularly, NMP is responsible for the pore-making function, and the NMP volatilizes from the wet film at a stable speed to form a porous microelectrode structure with uniform pore size and uniform distribution .

As an important part of the lithium ion battery, the conductive agent, although it occupies a small amount in the battery, it greatly affects the performance of the lithium ion battery, and it plays an important role in improving battery cycle performance, capacity utilization, rate performance and so on. The primary function of the conductive agent is to improve the electrical conductivity of the electron.In order to ensure that the electrode has a good performance of charge and discharge, a certain amount of conductive agent is usually added during the production of the electrode sheet to collect micro-current between the active substances and between the active substances and the fluid collector, so as to reduce the contact resistance of the electrode and accelerate the movement rate of electrons. In addition, the conductive agent can also improve the processability of the electrode sheet, promote the infiltration of electrolyte to the electrode sheet, and effectively improve the migration rate of lithium ions in the electrode material, reduce the polarization, so as to improve the charge and discharge efficiency of the electrode and the service life of the lithium battery. Conducting agents mainly include granular conductive agents such as acetylene black, carbon black, etc., conductive graphite is mostly artificial graphite, fibrous conductive agents such as metal fibers, carbon fiber grown by gas phase method, carbon nanotubes, etc., and new graphene and its mixed conductive paste are used as conductive agents.

Battery Copper foil is an anode material made of copper and a certain proportion of other metals.Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. Electronic information and lithium batteries are the mainstream application areas of copper foil. Copper foil is both a carrier of anode electrode active material in lithium ion batteries. It is also the collector and conductor of anode electrode electrons. Therefore, it has special technical requirements, that is, it must have good electrical conductivity, the surface can be coated with the anode electrode material without falling off, and it must have good corrosion resistance. As a key raw material for lithium-ion batteries, the thickness, tensile strength, elongation, uniformity, surface properties and other indicators of copper foil directly affect the cycle performance and energy density of lithium-ion batteries. The future development trend of copper foil for lithium ion battery 1. Copper foil has higher requirements for performance, accuracy and consistency; 2. The thickness is thinner, to meet the high volume capacity requirements of lithium ion batteries. The current direction is to develop copper foil with thickness less than 9m; 3. Micro-treatment of the surface to enhance the oxidation resistance, corrosion resistance and electrical conductivity, as well as the adhesion strength with the negative electrode active material; 4. In order to adapt to the polymer lithium ion battery and high capacity alloy type anode material, the development of two-dimensional and three-dimensional copper foil.
