New Energy Materials

To gear toward the global development trend of new energy industry, Haike Group established Shandong OBO New Material Co., Ltd. in 2014, which became the first batch of enterprises to realize the mass production of single-layer graphene. Anhui Xinheng New Materials Technology Co., Ltd. was founded in 2016, committed to the research, development and production services of high-end wet process diaphragm products. Subsequently, it acquired Power Carbon Technology Co., Ltd. in 2017, became the world's first owner of graphene modified high-capacity carbon technology. In the same year, the electrolytic solvent production line was built by Xinyuan. Haike Group will do all we can to boost the development of new energy sources to become the NO.1 in the world, to provide continuous and reliable electric energy for all kinds of energy storage products, and improve the charging efficiency and service time of lithium battery equipment to a considerable degree

Properties
Description
Lithium battery wet diaphragm
Thickness 5-20μm, porosity 38-46%, air permeability 150-250ml/s, tensile strength ≥1000-1300kgf/cm2, heat shrinkage 1.5%-5%, puncture strength≥400g
One of the four main materials of lithium batteries for digital, power and energy storage batteries. The main function is to directly contact the positive and negative electrodes, and at the same time, the lithium ions can freely shuttle between the positive and negative electrodes, providing the safety of the lithium battery. In the case of high temperature of the battery, the closed channel blocks the passage of lithium ions.
Graphene
Chip diameter: 5-20 μm (controllable); specific surface area > 500 m2 / g;
Oxygen content <13%; conductivity >600S/m
It has a large specific surface area and a certain conductivity, and is suitable for use in fields such as conductive additives and composite materials.
Graphene dispersion
Graphene is uniformly dispersed; the performance of the coating is 3600h, the adhesion is 19MPa, and the system has passed 4000h.
Graphene is uniformly dispersed and dispersed in the coating. In the coating, the performance of the product can be significantly improved, and the second is to replace the zinc powder and reduce the product cost.
