►Battery Material Division
Gredmann Group’s Battery MaterialDivision is dedicated to present high-class Li-battery industry materials, such as cathode, anode, separator, electrolyte, copper/Al foil, cathode/anode binder, Al laminated packaging and so on. We are proud to provide customers the best total solution and technical services.
Cathode Material:
(1) NCM
Gredmann Group represents Korean L&F's high-capacity advanced cathode active materials, which have high-energy density, high efficiency and safety of Li-ion battery. This NCM material is wildly adopted in full ranges of battery products of Korean international makers due to its’ unique coating technology and excellent material characteristics.
Product Characteristics:
①High Capacity; ②Low Remnants of Lithium; ③Surface Coating; ④Long Cycling Life
Product Applications:
① Power Tools; ②Electric Cars(EV/PHEV/xEV); ③Energy Storage Systems(ESS)
Anode Material:
(1) Natural Graphite
Gredmann Group represents Korean Posco’s natural graphite anode material, which have high capacity, high electrode density, fast charge and discharge and low temperature characteristics. With the unique coating technology and excellent product characteristics is also widely used in full ranges of battery products of Korean international makers.
Product Characteristics:
①High Capacity; ②High Electrode Density; ③Surface Coating; ④High Conductivity; ⑤Long Cycling Life; ⑥Anti-PC
Product Applications:
① Power Tools; ②Electric Motorcycles; ③Digital device/IT; ④Energy Storing System
(2) MCBC
Gredmann Group represents China Steel Chemical Corp’s MCMB, which is high quality and high characteristics of anode material for Li-ion battery by putting P-Coke through heat treatment and several chemical engineering processes with unique technology Because of tight structure among layers, small surface area, anisotropy and its particle size can be adjusted by controlling the process parameter.
Product Characteristics:
① High Capacity(350mAh/g); ②High Rate Discharge Ability; ③Long Cycling Life; ④Anti-PC
Product Applications:
①Power Tools; ②Electric Motorcycles; ③Digital Device/IT; ④Energy Storing System
Separator：
Gredmann Group represents the global leader, and distribute the professional separator. Our separator has the big market share and full range of products in the Separator Industry, providing excellent capacity and power, performance, size integrity, chemical and thermal reliability for Li-battery application.
Product Characteristics:
① Stretching Manufacture technique with Dry Process;
② Excellent corrosion resistance to the acid, alkali and most of chemical products. Uniform polyporous structure provides higher chemical and heat stability;
③ TD Shrinkage reduces internal shortage and increases high temperature size stability;
④ PP outer layer provides oxidation resistance whichincreases long cycling life and trickle charging performance;
⑤ PE inner layer provides high-temperature and high-speed shutdown performance.
Product Applications:
①Power Tools; ②EV; ③Energy Storage Systems(ESS); ④3C
Copper Foil:
Gredmann Group represents Copper Foil from Furukawa, this material has the highest product quality in the world and outstanding product characteristics. Recently, this famous material has been wildly welcomed and adopted by outside Japan and penestrates into the global Li-battery manufacturing compnay.
Product Characteristics:
① Excellent flexing resistance
② Excellent mechanical characteristics after heat treatment
③ Excellent surface smoothness
④ Excellent charge-discharge and not easy break
⑤ High safety
Product Applications:
①Power tool; ② EV; ③energy storage systems(ESS); ④ 3C
Conductive Graphite Fiber (VGCF):
Gredmann Group represents Conductive Graphite Fiber (VGCF), this material is specially designed to improve battery performance. It has excellent thermal conductivity, electrical conductivity and strength characteristics. Because the diameter ratio of graphite fiber is larger than carbon nano tube (CNT), our presenting material will be easier to disperse into the slurry, so as to be more widely used on Li-battery.
Product Characteristics:
①Improve electrical conductivity of battery plate;
② Improve rate discharge capacity;
③Improve electrolyte absorbent capacity of battery plate;
④Improve the durability of battery plate;
⑤Prolong the loops lifetime of the battery.
Product Applications:
①Power tool; ② EV/PHEV/xEV; ③energy storage systems(ESS); ④IT(Heavy)
