Negative electrode materials refer to the raw materials of negative electrodes in batteries (such as power batteries, consumer electronics, energy storage equipment and other lithium battery fields). The core materials of negative electrode materials are mainly divided into artificial graphite and natural graphite. At present, petroleum coke is the main raw material of artificial graphite, the core aggregate.
Petroleum coke is a product that is converted from light and heavy oil after crude oil is separated by distillation and then hot cracked. Due to the impact of the supply environment of petroleum coke market, the price of petroleum coke has lasted for nearly a year for last week. Before December 2021, the price of domestic petroleum coke was 4300 yuan / ton. In the first half of 2022, the price of domestic petroleum coke reached 5500-6000 yuan / ton. Up to July 2022, the price of petroleum coke has exceeded 7000 yuan / ton. The main reasons for the rise in the price of petroleum coke are as follows:
First of all, the supply in the domestic market has decreased, resulting in the market in short supply. The main reason for the reduction in domestic supply is the reduction of production or shutdown maintenance of domestic refineries based on environmental protection supervision, resulting in a reduction in supply.
Secondly, from the perspective of the import market, due to the impact of the epidemic and the uncertainty of the epidemic in various regions, the import transportation cycle has been greatly prolonged. Due to the impact of the epidemic, the import cycle of petroleum coke has been extended by 25-30 days compared with that before the epidemic. Therefore, the import cycle has increased, resulting in insufficient market demand and supply and rising market prices.
Finally, there is less inventory in the petroleum coke market. According to the CMRC Zhongyan survey, there is no large inventory in major domestic refineries, and most refineries set production based on sales.
Therefore, the above three reasons lead to the rise of market prices. In the short term, the price of Petroleum Coke will continue to rise.
