material characteristics: Graphene oxide is an oxide of graphene whose unique structure gives it outstanding physical and chemical properties. Small-size high-purity graphene oxide has a higher specific surface area and more abundant active sites, which enable it to play an important role in batteries. the application in batteries: High energy dens1
The application of ultra-pure single-layer graphene oxide in batteries is mainly reflected in the following aspects: Efficient charge and discharge: Because graphene oxide has a high specific surface area and rich functional groups on the surface, it can provide a larger electrode surface area when used as an electrode material, so that lith1
Vacuum film coating machine is widely used in various high temperature coating process, such as ceramic film, crystal film, battery electrode, special nano film

AOT-TBJ-180C is a small roll-to-roll coater for laboratory research, because it can coat continuously, it is suitable for pilot scale battery research work in colleges, universities and factories.
Lithium battery PE separator is made of polypropylene as the base material and forms a uniform microporous structure through processes such as biaxial stretching.
The functional film mainly made of polyethylene (PE) plays a key role in physically isolating the positive and negative electrodes to prevent short circuits.
The coating forms a dense barrier through high-temperature sintering, enabling the separator to withstand temperatures above 1800℃. This effectively blocks heat conduction during thermal runaway.
