Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal, consultancy Wood Mackenzie said on Monday.
The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.
Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on the Silicon Powder prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.
Overview of Nano Silicon Powder
Silicon is the most promising electrode material for next-generation lithium-ion batteries, with a specific capacity (3600 mAh/g) about 10 times higher than graphite (372 mAh/g). However, due to the significant expansion of the material (more than 300%) in the loaded (lithiation) state and the instability of the solid electrolyte interface layer (SEI), its use is severely restricted. The poor mechanical stability and chemical passivation properties of silicon electrodes make the cycle performance of silicon electrodes far unable to meet the requirements of battery systems, and stimulate a lot of research and suggestions to circumvent these limitations.
During the lithium insertion process, the volume of silicon changes so much (about 400%) that the silicon cracks and falls off the collector, causing the prototype lithium-silicon battery to lose most of its capacity in less than 10 charge and discharge cycles. The key to the success of large-capacity lithium-ion batteries is to solve the capacity and stability problems of lithium-ion silicon.
Silicon anode materials have shown great potential in improving the efficiency and energy storage capacity of lithium-ion batteries. Until recently, their main disadvantage was surface passivation by oxidation, a process that increases impedance and reduces the circularity of the anode. Our high-purity silicon anode materials can achieve high specific capacity without significantly affecting cycle life.
What are the applications of Nano Silicon Powder?
Silicon is the most promising kind of anode material in the next generation of lithium-ion batteries. Nano silicon anode materials are used in cylindrical, flexible and aluminum shell batteries. Our silicon anode powder can be dispersed in the battery solvent while preventing agglomeration. They are designed to stick seamlessly with other battery materials and produce uniform and stable coatings. Therefore, they are suitable for a range of applications, including lithium-ion batteries, photovoltaics, semiconductors, and electronics.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the Silicon Powder, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.
