以碳纤维为增强体，以碳或碳化硅等为基体，以化学气相沉积或液相浸渍等工艺形成的复合材料，主要包括碳/碳复合材料产品（碳纤维增强基体碳）、碳/陶复合材料产品（碳纤维增强碳化硅）等。强度大、热膨胀系数低、使用寿命长、灰分成份低、具有优异的保温性及韧性，且不易破碎，可有效降低生产能耗、提升设备使用寿命。
● 硅碳负极
硅碳负极材料被誉为下一代负极材料，可以替代石墨，拥有高能量密度，可显著提高电池负极材料的容量和电化学性能。目前协鑫拥有两种工艺路线，可同时制备第二代和第三代硅碳负极材料。高比容量+良好的快充性能，低膨胀、高电导、低阻抗。
● 石墨电极
主要以石油焦、针状焦为原料，煤沥青作结合剂，经煅烧、配料、混捏、压型、焙烧、石墨化、机加工而制成。用于硅矿石高温冶炼、加热材料。
Carbon fibre as reinforcement, carbon or silicon carbide, etc. as matrix, chemical vapor deposition or liquid phase impregnation and other processes to form a composite material, mainly including carbon / carbon composite products (carbon fibre reinforced matrix carbon), carbon / ceramic composite products (carbon fibre reinforced silicon carbide) and so on. It has high strength, low coefficient of thermal expansion, long service life, low ash composition, excellent heat insulation and toughness, and is not easy to break, which can effectively reduce production energy consumption and enhance the service life of equipment.
● Silicon Carbon Anode
Silicon-carbon anode material is regarded as the next-generation anode material, which can replace graphite, has high energy density, and can significantly improve the capacity and electrochemical performance of battery anode material. At present, GCL has two process routes, which can simultaneously prepare second-generation and third-generation silicon-carbon anode materials. High specific capacity + good fast charging performance, low expansion, high conductivity and low impedance.
● Graphite Electrode
Mainly made of petroleum coke and needle coke as raw materials, coal pitch as binding agent, calcined, batching, mixing and kneading, pressing, roasting, graphitising and machining. It is used for high temperature smelting of silica ore and heating materials.
