Generally, the theoretical expression of a compound formed by lithium in a carbon material is LiC6, and the theoretical specific capacity in stoichiometry is 372 mAh / g. When some metals, such as Sn, Si, Al, are embedded in lithium, a lithium-metal alloy with a high lithium content High power Graphite Electrode will be formed. PW series, BF series, nano-conductive materials, multiple composite anode materials for lithium-ion power batteries, etc.

According to its composition, it can be divided into: lithium transition metal nitride, transition metal oxide, and nano alloy materials. The charge and discharge curves are very flat and there is no discharge hysteresis, but the capacity decreases significantly. For example, when Li3FeN2 is used as the negative electrode of LIB, the discharge capacity is 150mAh / g and the discharge potential is near 1. The theoretical value of LiC6 is 372mAh / g It is increased to 700mAh / g-1000mAh / g, so the specific energy of the lithium ion battery is greatly increased. In the field of lithium-ion battery anode materials, the company's lithium-ion battery anode materials have stood at the forefront of the new generation of domestically produced materials, representing the direction of graphite deep processing. Into.), 1,200 tons of artificial graphite anode materials (SAG series,

Its first discharge capacity is above 360mAh / g, its first efficiency is greater than 95%, and its compaction ratio reaches 1. Compared with tin oxide (SnO / SnO2), the cycle life of tin-based composite oxides has been greatly improved, but it is still difficult to meet industrial standards. There are many types of carbon materials. The company has an annual output of 1,800 tons of natural composite graphite (MSG, AMG, 616, 717, 818, etc

NAG series, 316 series, 317 series), 3000 tons of spherical graphite (SG), 5000 tons of natural micro-powder graphite and 600 tons of lithium manganate cathode materials are continuously expanding the production scale. Non-carbon anode materials In recent years, research on LIB non-carbon anode materials has also been extensive. The main problems of alloy anode materials are low efficiency and cycle stability for the first time.
