 <2021> Technology Trend and Market Outlook for Anode Materials of Lithium-Ion Secondary Batteries (by 2030)

 

 

As of 2021, graphite is being utilized as the anode material for most lithium-ion secondary batteries. For nearly 30 years from the time, when Sony firstly commercialized lithium secondary batteries in 1991, until now, carbon-based materials ? including graphite ? have firmly maintained the throne of anode materials without any major changes.

 

The reason why graphite has been used as an anode material of Li-ion secondary batteries for such a long time is that it more satisfies the following requirements, compared to other materials:

 

1.High charge and discharge capacity (per unit weight or volume)

 

2.Initial irreversible capacity losses must be small

 

3.Must have excellent life characteristic, such as charge/discharge cycles

 

4.High electrical conductivity and ion diffusion rate 

 

5.Small volume change caused by Li intercalation/de-intercalation

 

6.Must be made of eco-friendly materials

 

7.Easiness to manufacture and low price

However, as applications, such as electric vehicles (xEV), power tools, e-mobility, and drones, that require very tough requirements have appeared one after another and then become the core of the market, in order to satisfy properties, such as high energy density, long life, and high charging/discharging power, which are difficult to meet with conventional graphite materials, the need for a significant improvement in the performance of the existing carbon-based graphite anode materials or for a new anode material is increasing.

 

 

 

It is Silicon-based and Li-metal that are representative candidates for new anode materials that are being researched/developed or partially applied to meet these needs, and improvements for the existing carbon-based anode materials are being implemented in parallel with it; in this report, we faithfully reflected these recent trends and R&D status.

 

 

 

Particularly, the latest technology trends centered on the Silicon-based and Li-metal were discussed in depth, and we also examined the performance improvement of existing materials and new substances and the R&D status of hybrid products. In addition, we further discussed in detail the current status of anode material production for each anode material manufacturer in Japan, China, Korea, and other countries, and lastly, in the market sector, with respect to the status for the past 5 years, we analyzed the trends of LiB makers in the consumer side, and the industry pipelines by country, company, and anode material chemistry for the performance of anode material suppliers in the supplier side. In addition to that, we also forecasted the anode material market demand by 2030, against the background of the EV and ESS markets ? which are expected to grow explosively.
