Energy storage growth reshapes metal demand landscape: lithium, copper, and vanadium become key beneficiaries.

Introduction

The global energy transition is extending from power generation to energy storage, and the explosive growth of the energy storage industry is having a profound impact on the upstream metal supply chain. As core infrastructure for balancing the intermittency of renewable energy, the large-scale deployment of energy storage systems is not only changing the way power systems operate, but is also reshaping the demand landscape for key metals such as lithium, copper, aluminum, and vanadium.

From China's hundred-gigawatt-scale energy storage expansion plan to the record growth in U.S. battery energy storage installations, energy storage has become a key hub in the global Clean Transportation and Energy Transition process. The changing metal material demand behind this is becoming a new reality that companies across the Battery Supply Chain must face.

Industry Background

The core function of energy storage is to smooth out the fluctuations of wind and solar power and ensure the stable supply of clean electricity. As global renewable energy installed capacity surges, the strategic position of energy storage systems is becoming increasingly prominent.

According to data from China's National Energy Administration, from January to September 2025, China's solar power installed capacity reached 1.13 TW, a year-on-year increase of 45.7%; wind power installed capacity reached 580 GW, up 21.3% year-on-year. The rapid expansion of renewable energy has created enormous demand space for the energy storage market.

According to an action plan released by the Chinese government in September 2025, China will add 100 GW of energy storage capacity from 2025 to 2027. By the end of 2027, total installed capacity will more than double from the 2024 level, reaching 180 GW. The United States is also accelerating energy storage deployment, with battery energy storage installations in the second quarter of 2025 hitting a record high for a single quarter. At the current pace, the United States will add approximately 19 GW and 52.5 GWh of energy storage capacity in 2025, up 53% and 45% year-on-year, respectively.

Key Developments

The growth in energy storage demand is being directly transmitted to the metal materials market, with lithium benefiting the most significantly. As the mainstream energy storage technology, lithium-ion batteries are becoming increasingly economically viable for large-scale storage projects due to continuously falling costs and improving efficiency. Argus data shows that the cost of lithium iron phosphate cathode materials has fallen to US$11.12/kWh, down 83% from the historical peak in November 2022.

In this context, energy storage has become the second-largest source of lithium demand, accounting for 12-13% of the market share. Argus Consulting forecasts that by 2035, lithium demand from energy storage systems will grow to 340,000 tonnes of lithium carbonate equivalent (LCE).

Beyond lithium, the construction of energy storage systems and infrastructure is also driving growth in demand for metals such as copper and aluminum. Copper is a key material for power transmission, while aluminum is widely used in the structural and thermal management components of energy storage systems. Argus expects China's copper demand from electric vehicles and the energy transition sector in 2025 to grow 18% from 2024, reaching 3 million tonnes.Meanwhile, the diversification trend in energy storage technology is opening up new demand space for other metals. The development and commercialization of alternative technologies such as vanadium redox flow batteries (VRFB) and sodium-ion batteries are accelerating. Market participants estimate that around 5 GWh of vanadium flow battery installations will be completed globally in 2025, which will consume approximately 35,000 tonnes of vanadium (in V2O5 equivalent).

Industry Impact

The reshaping of metal demand driven by energy storage growth is profoundly affecting the competitive landscape of the global Battery Supply Chain. For suppliers of key metals such as lithium, copper, and vanadium, the energy storage market is becoming another core growth engine after electric vehicles.

The demand structure of the lithium market is undergoing changes. The continuous increase in the share of energy storage means that lithium producers need to re-examine their customer structures and long-term contract strategies. As a key metal for power infrastructure, copper's demand growth comes not only from energy storage itself, but also from grid upgrades and charging infrastructure construction brought about by the entire Energy Transition.

The commercialization progress of vanadium redox flow batteries also provides new market opportunities for vanadium producers. Although the current scale is still small, the growth in long-duration energy storage demand may make vanadium an important participant in the energy storage metals market.

For battery manufacturers, the expansion of the energy storage market is driving adjustments in product structure. The share of lithium iron phosphate batteries in the energy storage field continues to rise, and this technology route's high sensitivity to cost is also forcing upstream material companies to optimize production processes.

Challenges and Risks

Despite the strong growth prospects of the energy storage industry, the metal demand side still faces multiple challenges. The first is the potential risk of oversupply. Rapidly expanding capacity may lead to an imbalance between supply and demand in the energy storage battery market, thereby affecting the stability of upstream metal prices. According to data from the China Industrial Association of Power Sources, in the first half of 2025, China's newly commissioned lithium-ion energy storage battery capacity was 142.2 GWh, while capacity under construction during the same period reached 752.5 GWh. However, a considerable portion of newly built energy storage power stations has not yet been put into actual use, laying hidden risks for future market supply-demand balance.

Second, the volatility of metal prices poses challenges to manufacturers' cost control. The prices of metals such as lithium, copper, and vanadium are affected by multiple factors including the macroeconomy, geopolitics, and supply-demand relationships. Significant price fluctuations may erode the profit margins of energy storage system integrators.

In addition, the escalation of geopolitical tensions, especially the tariff measures imposed by the United States, is creating obstacles to the global expansion of Chinese energy storage batteries. China is the dominant producer of energy storage batteries globally, with Chinese energy storage battery shipments accounting for more than 90% of the global total in 2024. The U.S. domestic energy storage battery industry, however, is developing relatively slowly, and trade barriers may further distort the global supply chain layout.Finally, China's energy storage market is still waiting for a more efficient electricity market mechanism. The profitability model of energy storage mainly relies on peak-valley electricity price arbitrage, but the current pricing mechanism is often constrained by narrow peak-valley spreads and a lack of real-time price signals, which limits the economic viability of energy storage projects and may indirectly affect long-term demand for metal materials.

Future Outlook

The impact of the energy storage industry on metal demand will continue to deepen over the next decade. As the share of renewable energy worldwide continues to rise, the essential-demand attribute of energy storage will become more prominent, driving a fundamental shift in the demand structure for metals such as lithium, copper, aluminum, and vanadium.

The diversification of technology routes will become an important trend in the future. The advantages of vanadium redox flow batteries in long-duration energy storage may enable them to gradually replace lithium-ion batteries in specific scenarios, and the industrialization of sodium-ion batteries will also reduce dependence on lithium. This technological evolution will lead to continued divergence in the metal demand landscape, and supply chain companies need to position themselves in advance.

It is worth noting that the growth of the energy storage market is not linear. The intensity of policy support, the progress of electricity market reform, and the speed of technological breakthroughs will all affect the pace of energy storage installation, which in turn will transmit to the metal demand side. For mining companies, battery materials, and metal traders, gaining an in-depth understanding of the dynamic changes in the energy storage industry will be key to seizing future market opportunities.

Conclusion

The rise of the energy storage industry is shifting the logic of metal demand from being driven solely by electric vehicles to a pattern driven by both electric vehicles and energy storage systems. This shift not only affects the supply-demand balance of metals such as lithium, copper, and vanadium, but will also profoundly reshape the global battery materials supply chain and the geoeconomic landscape of critical minerals. Against the backdrop of the Energy Transition, the construction of energy storage infrastructure will become the core nexus connecting renewable energy and clean transportation, and the sustainable supply of metal resources is the fundamental guarantee for the smooth advancement of this process.
