Andy Home: The ROI-EV Revolution continues, but the battery metals are losing their charge.

The third year has been tough for battery metals like lithium, nickel and copper as the three markets struggled to absorb the supply wave that followed the price boom of 2022.

The electric vehicle revolution continues. The demand for metals and batteries that power them is growing at an accelerated rate.

It is only a matter time before the current glut of supply is absorbed by demand.

This was at least the hope.

Chinese companies are, however, embarking on a "simultaneous" technological revolution, as they seek to develop batteries that are ever more powerful at a lower cost.

Battery chemistry evolves quickly and it is already apparent that not every battery metal will be successful in the fierce competition between materials.

CHINA POWERS UP

The road to electrification is currently bumpy. The U.S. president Donald Trump has reversed the Biden administration’s EV subsidies, and the European Union deferred the phase-out of combustion engine vehicles beyond 2035.

The underlying momentum remains unabated. According to Rho Motion, global EV sales grew by 21% on an annual basis to reach 18.5 million cars in the first eleven months of 2025.

China continues to be the driving force behind the global technological shift. This year, the world's biggest EV market grew by 19% and accounted for 62% global sales.

No one should be surprised that Chinese companies are at the forefront of battery chemistry.

The Chinese EV market is now dominated by batteries using lithium-iron-phosphate (LFP) chemistry. These batteries are cheaper and safer than those that use a combination nickel, cobalt, and manganese. The performance gap between them and those using NCM is also steadily narrowing.

LFP was responsible for 48% global EV batteries in 2017. Macquarie Bank has revised its forecast to expect that this share will rise to 65% in 2029. This is a significant increase from the previous 49%.

Nickel and Cobalt in the Slow Lane

It is not good news for either Indonesia or the Democratic Republic of the Congo - the two largest nickel and cobalt producers in the world.

Indonesia has not tempered its production growth in order to reflect the reality of new batteries, creating a tsunami surplus metal.

The country's nickel is increasingly being shipped to a warehouse at the London Metal Exchange (LME), rather than to a battery-precursor plant.

LME warehouse stock - registered or off-warrantee - has exploded to 338.900 tons.

This is only the second time in 2021 that the LME nickel price fell below its long-term support of $15,000 per ton. The pressure on Indonesian policymakers?to curb their nickel boom has increased.

Cobalt prices are also in a similar situation of chronic oversupply. Congo stopped exports in February, and then introduced a quota-based system in October.

The slow implementation of new rules led to the complete stoppage of shipments of cobalt-based intermediates to Chinese refineries.

Congo's supply discipline could become a supply shock. This could be costly for a nickel-based metal that already struggles to maintain its share in battery chemistry.

The price volatility of cobalt and ethical issues associated with the artisanal mining industry in Congo are a concern for automakers.

The events of this year will only exacerbate these concerns and could lead to a greater push for cobalt to be removed from the equation.

LITHIUM DOMINANT ... FOR NOW

China's shift to LFP chemistry reinforces the importance of lithium.

Adamas Intelligence, a consultancy, estimates that 60,900 tonnes of lithium was deployed on roads worldwide in September. This is a 25% increase year-over-year, which matches the growth of total battery deployment. Nickel and cobalt lagged behind with deployment growth rates of 10% and 15% respectively.

But lithium is also facing a new challenge.

The Chinese battery giant CATL is a pioneer in the development of'sodium-ion Batteries. Naxtra is the latest version of this battery that will match or even surpass LFP batteries, which are replacing NCM chemistry. It also does so at lower costs.

Robin Zeng, the billionaire founder of CATL, believes that sodium-ion battery could replace up to half of the market for LFP Batteries.

The metal is a popular choice for storage batteries for power grids, which are a growing market.

According to Benchmark Mineral Intelligence, global installations of battery-based energy storage systems increased by 38% in the first ten months of 2025.

Ford Motors has announced a charge of $19.5 billion on EV investments. At the same time, it is committing to invest $2 billion in batteries for energy storage system.

HARD WIRED

The EV battery materials landscape has changed dramatically since 2022 when the prices of lithium, cobalt, and nickel were all surging, on the assumption that these three metals would be at core for electric mobility.

This is no longer true. The battery chemistry continues to evolve at a breakneck pace, thanks to unprecedented research and development.

In 10 years, it is impossible to know what will power electric vehicles.

It is certain that copper will remain essential for wiring vehicles and charging infrastructure. Aluminium will likely remain the preferred material for body frames due to its lightweight.

The ultimate winners of the EV revolution may not be the metals that directly power a vehicle, but those who enable it.
