Canada ranked 4th, US 6th in lithium-ion battery supply chain

A new ranking for 2020 by Bloomberg’s clean energy, new materials and commodity research arm (BloombergNEF) shows China dominating the global lithium-ion battery supply chain, quickly surpassing Japan and Korea, leaders for most of the previous decade. 

China’s dominance is based on its large domestic battery demand, 72GWh, and control of 80% of the world’s raw material refining, 77% of the world’s cell capacity and 60% of the world’s component manufacturing, according to data from BNEF.

Kwasi Ampofo, BNEF’s lead analyst covering battery raw materials, says China’s large scale investments into mining and refining has given it the advantage over Japan and Korea:

“Other countries seeking to be dominant players in the overall value chain may need to support upstream metals mining and refining development, while also formulating policies that will safeguard the environment.”

Canada, in fourth place, is boosted by its access to raw materials and environmental strengths but brought down by a relatively low score for regulation, infrastructure and innovation, and middling demand for batteries in electric vehicles and energy storage. 

“Key distinguishing factors are the environmental footprint of industry, the availability of cheap but clean electricity, a technically skilled labor force, and incentives driving battery demand. These factors may be more important than a monopoly on one specific critical metal”

Currently at number 6, the US is forecast to slot in at number three by 2025, improving its metrics across the board.  

James Frith, BNEF’s head of energy storage, says the next decade will be particularly interesting as Europe and the US try to create their own battery champions:

“While Europe is launching initiatives to capture more of the raw material value chain, the US is slower to react on this.”

BNEF says “if the US were to increase its investment in raw materials and promote EV adoption, it could overtake Japan and China to be number one in 2025.”

As EV demand grows there is an increasing need for cell manufacturing facilities close to automotive production. This has led to a boom in European cell plants, and the rest of the supply chain is also slowly making its way to Europe, according to the report. 

The introduction of carbon border taxes as proposed by the European Commission and Joe Biden, the US Democratic presidential candidate, could give regions or countries leverage to secure localized supply chains. 

Sophie Lu, head of metals and mining at BloombergNEF, says a key concern of many raw materials producing countries is how to leverage resource wealth into more value-add, and attract further downstream investments, like battery manufacturing:

“Key distinguishing factors are the environmental footprint of industry, the availability of cheap but clean electricity, a technically skilled labor force, and incentives driving battery demand. These factors may be more important than a monopoly on one specific critical metal.”


Raw materials are ranked on resource availability, mining capacity and refining capacity. Cell & components are ranked based on the manufacturing capacity of electrolyte salts and solutions, anodes, cathodes, separators and cells. Environment is ranked based on electricity grid carbon emissions, renewable policy, environmental health and ecosystem health. RII is ranked based on infrastructure, policy, R&D investment and STEM education. Demand is ranked based on lithium-ion battery demand from transport and stationary storage. Source: BloombergNEF
