For lithium ion batteries, the cathode materials that can be used should meet the characteristics of large reversible capacity, high potential and stability, non-toxic and low production cost. At present, lithium iron phosphate is the most common cathode material for lithium ion batteries. However, LiFePO4 has poor electrical conductivity and low lithium ion mobility. If LiFePO4 material is combined with graphene, its conductivity and multiplier performance can be improved theoretically.

Introduction to the graphene materials
Graphene Oxide is a two-dimensional planar nanomaterial composed of carbon atoms with a hexagonal honeycomb lattice，the c-c bond length is 0.141nm, the theoretical density is about 0.77mg/m2, and the thickness is only about the diameter of a carbon atom. Carbon atoms participate in hybridization in the way of sp2, and electrons can smoothly conduct between layers, so graphene conducts electricity extremely well. It is the material with the smallest resistivity known, which is one of the reasons why graphene has a promising future in batteries.

Metalized Cast Polypropylene (CPP) Films CPP films are transparent cast polypropylene films designed to offer high performance, great appearance and easy converting for flexible packaging and other applications.

The Electrode Coating Machine is the key equipment for the production of lithium battery electrode. Because it directly affects the subsequent rolling operation, and even affects the performance of the entire battery. At present, the mainly lithium battery electrode coating process is: scraper type, roll to roll transfer coating type and a slit extrusion type. General speaking, laboratory equipment adopts the scraper type, the 3C battery adopts the roll to roll transfer coating type, and the power battery adopts the slit extrusion type.

The main components of lithium ion battery include cathode, cathode, electrolyte, membrane, etc. The storage and release of lithium ion energy is realized in the form of REDOX reaction of electrode materials, and the cathode active material is the most critical core material of lithium ion battery.
Professor GOODENOUGH, the father of lithium battery, has made a great contribution to the research of lithium battery cathode materials. In 1980, while working at the university of Oxford in the United Kingdom, he discovered that lithium cobalt oxide (LCO) could be used as a lithium cathode. In 1981, he mentioned the feasibility of lithium nickelate (LiNiO2, also known as LNO) as a cathode material in the LCO patent. In 1983, he made his first attempt to use lithium manganate (LMO) as a cathode material for lithium-ion batteries. In 1997, he developed lithium iron phosphate (LiFePO4, or LFP), which is the cathode material of olivine structure. In addition, to solve the problem of unstable properties of lithium nickelate, a large amount of research has been conducted in the area of doping modification by Prof. DAHN from Canada and Prof. Sumika kosuki from Japan. In 1997, toda applied for the first patent of lini1-x-ycoxalyo2 (NCA). In 1999, liu zhaolin and yu aishui et al. from the university of Singapore introduced Mn modification on the basis of lithium ni-co (lini1-x-ycoxmnyo2, namely ternary material and NCM).

Introduction:
Polyvinylidene fluoride binder(PVDF) is currently the most commonly used oil binder in the lithium ion battery industry. It is a non-polar chain polymer binder. It is characterized by strong oxidation resistance, good thermal stability and easy dispersion. N-methylpyrrolidone (NMP) is required as a solvent. This solvent has a high volatilization temperature, has a certain environmental pollution, and is expensive.
