Initially, silicon and graphite was being used in the lithium ion batteries. But due to limited quantity of graphite as a natural resource the companies started using only silicon within the lithium ion batteries as it increases the lithium ion capacity as well as the storage capacity. Silicon has major usage in electric vehicle which is one of the fastest growing markets. China & Japan and other Asia-Pacific countries have started using electric vehicles within their domestic territory which has led to the increase in the usage of silicon based anode batteries. This is still at a developing stage because the expansion of the size while charging and discharging is quite high.
Some of the recent developments that have taken place in this market are as follows:
- In December 2018, Elkem Silicones opened a new R&D centre at its Saint-Fons site, in Lyon, France. This new R&D centre is built in order to support its global growth with the development of high value-added silicone specialties
- In August 2018, Elkem ASA opened its new plant for foundry products in Paraguay. The company has expanded its business in Latin America by opening its first plant there.
- In April 2018, Targray showcased its new product line of advanced materials for lithium-ion cell at the Battery Show Europe, 2018, in Hannover, Germany
Furthermore, China is the largest producer of electric vehicle and electronic products. For instance, in 2017, China has produced approximately 600 thousand electric vehicles. Hence, there is big opportunity in the China as an electric vehicle needs high storage capacity batteries and fast chargeable batteries. For instance, in October 2018, Huawei Consumer Business Group has patented lithium-silicon battery that has fast-charging capability and better safety. Additionally, BTR New Energy Material Ltd is one of the leading the company for providing silicon anode material for lithium ion batteries.
In 2017, China has produced more than 41.70 million mobile phones and launch 97 newly models. Hence, this demands innovations and enhancements when it comes to storage capacity of mobile phones and silicon has comes across as one of the better anode material in electronic devices such as smart phones due its high storage capacity and fast charging.
Silicon anode material is at its early phase but there are many developments and innovation going on to overcome the challenges arrived for silicon anode material.
For instance,
- Ashland has developed Soteras MSi binder which can increase the 30% better capacity retention and reduce the swelling.
- Norwegian researchers have discovered better way to stabilize silicon anode in lithium ion batteries named as SiliconX which is quite different from pure anode material battery as battery material made of pure anode though holds huge charging capacity but deterioration rate is higher whereas in case of siliconX the charging capacity is higher and has stable life.
Proper innovation and development can make silicon material more suitable for lithium ion batteries and may replace traditional anode materials such as graphite.
BTR New Energy Material Ltd dominated the Silicon anode battery market and accounts for the highest market share in 2018 which is followed by Targray Group, Elkem ASA, SHIN-ETSU CHEMICAL CO., LTD., JSR Corporation, Albemarle Corporation, NanoGraf Corporation, Ashland, Orange Power Ltd., and Nexeon Limited.
