Can the Democratic Republic of the Congo produce lithium-ion battery cathode precursor materials?
London and Kinshasa, November 24, 2021 – The Democratic Republic of the Congo (DRC) can leverage its abundant cobalt resources and hydroelectric power to become a low-cost and low-emissions producer of lithium-ion battery cathode precursor materials.
How much cobalt does the DRC produce?
“The DRC produces about 70 per cent of global cobalt but captures just 3 percent of the battery and electric vehicle value chain.
How can Africa extend its access to the battery industry?
In so doing, the country and the rest of Africa can extend their access from the USD271 billion battery precursor segment to the more lucrative USD1.4 trillion combined battery cell production and cell assembly segments of the battery minerals global value chain.
What is the DRC's cobalt supply chain MoU?
The MOU supports the DRC and Zambia’s goal of building a productive supply chain, from the mine to the assembly line, while also committing to respect international standards to prevent, detect, and take legal action to fight corruption throughout this process. The DRC produces more than 70 percent of the world’s cobalt.
How much would a DRC plant cost?
This is three times cheaper than what a similar plant in the U.S. would cost. A similar plant in China and Poland would cost an estimated $112 million and $65 million, respectively. Precursor material produced at plants in the DRC could be cost competitive with material produced in China and Poland but with a lower environmental footprint.
Why is the DRC a cost competitive country?
“The DRC’s cost competitiveness comes from its relatively cheap access to land and low engineering, procurement and construction, or EPC, cost compared to the U.S., Poland and China,” said Kwasi Ampofo, lead author of the report and BNEF’s head of metals and mining.
