Description

There are three issues below that continue to be issued regarding anode materials for secondary batteries.

1) Expansion of silicon anode materials due to fast charging issues

2) In relation to IRA, subsidies cannot be applied to Chinese graphite anode materials, and as a countermeasure to this, graphite sourcing sources outside of China are being discovered.

3) R&D on anode materials for next-generation batteries (Sodium-ion batteries, All-solid-state batteries)

First, 1) Silicon anode materials are being driven strongly due to the need for improved energy density and fast charging due to high specific capacity, but the biggest issue is that a dominant silicon anode material platform has not yet emerged.

SiOx and Si-C, which are currently the mainstream silicon anode materials, are still quite expensive, and it is difficult to say that technological and price superiority has yet been established compared to new technologies, products, and manufacturing methods currently being researched or developed. Currently, more than 100 battery companies, material companies, mid-sized companies, start-ups, or academic/research institutes around the world are conducting various research and development and product launches on silicon anode materials, so technologically advanced products and manufacturing methods will emerge in the future. In this report, we investigated these silicon anode material companies in detail.

Second, 2) discovering sourcing sources for graphite anode materials outside of China. Currently, 98% of LIB anode materials are graphite, and Chinese companies account for more than 90% of graphite supply. In accordance with the IRA bill proposed by US, it was initially decided not to provide subsidies for xEV batteries containing anode materials manufactured by companies in foreign countries of concern (FEOC) such as China from January 2025, but it was difficult to apply this in reality. Therefore, in May 2024, they decided to postpone the triggering of these conditions for two years and apply them from January 2027.

Although we have gained two years of time, we must immediately discover sources for graphite anode materials outside of China. Therefore, we need to look for graphite companies in the US or Europe, but it is not easy to find a suitable supplier in terms of technology and quantity. In this report, we also investigated the status of non-Chinese graphite anode material companies in detail, such as in Australia, Europe, and the United States.

Lastly, 3) R&D on SIB or ASB anode materials. Hard carbon is mainly used as the anode material for sodium-ion batteries, which adopted sodium (Na) as a transport material in batteries instead of lithium (Li), which has a limited amount of mining. In addition, in some silicon anode materials, porous hard carbon is used as a support for nano silicon, so hard carbon is considered an important material that can be used as the anode material among materials other than graphite and silicon.

In some cases, carbon-based materials (graphite, hard carbon) or silicon are used as anode materials for all-solid-state batteries (ASSB), but Li-metal is also being continuously reviewed, so if Li-metal is used, the scope of secondary battery anode materials is expected to be expanded. We should be interested in the trend of hard carbon, which is an amorphous carbon material, or lithium anode material, a complete metal. Representative new anode material candidates that are being researched/developed or partially applied in line with this trend include silicon-based and Li metal, and improvements to existing carbon-based anode materials are also being carried out in parallel, and research on anode-free and fast charging technology is actively underway. This report reflects these recent trends and R&D status.

In particular, the latest technological trends centered on silicon-based materials and Li metal were discussed in depth, and the performance improvement of existing and new materials and the R&D status of hybrid products were also examined. This report also looked at industry trends in fast charging technology design and anode-free technology.

In addition, this report analyzed the use of anode materials and SCM of major battery companies in detail for the past three years. Each type (natural graphite, artificial graphite, silicon-based) of supply-chain companies were divided into Tier1, Tier2, and countries, and more than 100 companies were analyzed in detail.

We hope this report will be helpful in analyzing the global secondary battery market, anode material market and in business strategy.
