Introduction
Energy storage has emerged as the linchpin of our global energy transition. The question is no longer whether we can achieve a sustainable energy future, but how quickly we can scale the storage technologies that make renewable energy reliable and accessible. From lithium mines in Australia to gigafactories in China, from grid-scale installations in California to home batteries in Germany, the energy storage ecosystem has matured into a complex, interconnected network that underpins our modern economy.
The urgency has never been greater. Climate commitments demand rapid decarbonisation, grid stability requires flexible storage solutions, and electric mobility needs reliable, fast-charging infrastructure. Yet beneath these headline requirements lies a sophisticated supply chain story—one that spans continents, involves cutting-edge chemistry, and requires unprecedented coordination between miners, refiners, manufacturers, and end-users.
This year marks a pivotal moment. We're witnessing the convergence of several trends: supply chain diversification away from single-source dependencies, breakthrough battery chemistries moving from lab to commercial scale, and intelligent deployment strategies that optimise storage across multiple applications. Having spent over a decade navigating these waters, I want to share what I'm seeing from the ground up—from the mine to the megawatt-hour.
My Background
As co-founder and Editor-in-Chief of BatteryMinerals.org, I've had the privilege of observing this industry's evolution from multiple vantage points. My journey began 15 years ago in China, where I witnessed firsthand the rapid scaling of battery manufacturing and the emergence of Chinese companies as global leaders in lithium-ion production. Those years taught me that understanding battery technology requires more than just knowing the chemistry—you need to understand the entire value chain, from raw material extraction to recycling.
The subsequent five years in Thailand then provided a different perspective, particularly on how Southeast Asian markets are positioning themselves within the global battery ecosystem. Thailand's emergence as an EV manufacturing hub, supported by government incentives and foreign investment, exemplifies how nations are strategically aligning themselves with the energy transition. Working across raw materials sourcing, battery production, and electronics distribution has given me a unique view of how these sectors interconnect and influence each other.
This experience has shaped my understanding that energy storage isn't just about technology—it's about geopolitics, supply chain resilience, and the delicate balance between innovation and scalability. Through BatteryMinerals.org, we've built a community of professionals who share insights across this complex landscape, fostering collaboration between upstream miners and downstream manufacturers.
Supply Chain Deep Dive
The foundation of any battery revolution lies in its raw materials, and 2025 has brought both challenges and opportunities across the critical mineral supply chain.
Lithium remains the star performer, though the market has matured significantly from the speculative heights of 2021-2022. Australian spodumene production has stabilised, with major players like Albemarle and Tianqi Lithium optimising their operations for consistent, high-quality output. However, the real story is in processing capacity. China continues to dominate lithium carbonate and hydroxide refining, processing roughly 60% of global lithium despite producing only 13% of the raw material. This concentration has prompted urgent diversification efforts, with new refining capacity coming online in North America and Europe.
Cobalt supply has become more predictable, though ethical sourcing remains paramount. The Democratic Republic of Congo still supplies about 70% of global cobalt, but responsible sourcing initiatives have matured. Companies are increasingly investing in mine-to-market traceability systems, and alternative sources from Australia, Canada, and recycling are gradually reducing dependence on DRC supply. The shift towards lower-cobalt chemistries like LFP (lithium iron phosphate) has also reduced pressure on this critical mineral.
Nickel markets have experienced significant volatility, particularly following geopolitical tensions affecting Russian supply. Indonesia has emerged as the dominant force, leveraging its vast laterite deposits and Chinese investment to build integrated nickel-to-battery-chemical supply chains. The challenge remains in producing high-purity nickel suitable for battery applications, where sulfate-grade material commands premium pricing.
Graphite represents perhaps the most overlooked critical component. China produces over 80% of processed battery-grade graphite, creating a strategic vulnerability that Western governments are finally addressing. New synthetic graphite facilities in the US and natural graphite projects in Canada and Australia are coming online, though scaling these operations to match Chinese efficiency and cost remains challenging.
Southeast Asia's role has evolved beyond simple processing. Countries like Indonesia and the Philippines are developing integrated value chains, from raw material extraction through to precursor chemical production. This vertical integration, often supported by Chinese investment and technology, is reshaping global supply dynamics and reducing the traditional linear flow from mine to market.
Battery Technologies
The battery technology landscape in 2025 is characterised by pragmatic evolution rather than revolutionary breakthroughs. Each chemistry has found its optimal applications, and the focus has shifted from seeking a single winner to deploying the right technology for each use case.
Lithium Iron Phosphate (LFP) has claimed dominance in many applications where energy density takes a back seat to cost, safety, and longevity. Chinese manufacturers like BYD and CATL have driven costs below $60/kWh at pack level for large-scale deployments, making LFP the chemistry of choice for grid storage and many EV applications. The technology's thermal stability and cycle life exceeding 6,000 cycles have made it particularly attractive for stationary storage, where space constraints are less critical than in mobile applications.
Nickel Manganese Cobalt (NMC) batteries continue to evolve, with NMC 811 and newer high-nickel formulations offering energy densities approaching 300 Wh/kg at cell level. These remain essential for applications requiring maximum range, particularly premium EVs and aerospace applications. However, the higher cost and thermal management requirements have limited their adoption in price-sensitive markets.
Solid-state batteries have moved closer to commercialisation, though 2025 has been more about pilot production than mass deployment. QuantumScape, Toyota, and Samsung SDI have all demonstrated promising prototypes, with energy densities exceeding 400 Wh/kg and significantly improved safety profiles. However, manufacturing scalability and cost remain significant hurdles, with commercial viability likely still 3-5 years away for most applications.
Sodium-ion technology has emerged as a legitimate alternative for specific applications. CATL's commercial sodium-ion cells, while offering lower energy density than lithium-ion, provide compelling economics for grid storage and short-range EVs. The abundance of sodium and the ability to use existing lithium-ion manufacturing equipment make this technology particularly attractive for emerging markets and applications where cost trumps performance.
The R&D landscape has shifted towards incremental improvements and manufacturing innovation rather than entirely new chemistries. Silicon anodes are gradually being incorporated into commercial cells, offering 10-15% capacity improvements. Advanced battery management systems are extracting more performance from existing chemistries through sophisticated algorithms and real-time optimisation.
Downstream Deployment
The deployment of energy storage in 2025 reflects a maturing market that has moved beyond early-adopter enthusiasm to pragmatic, value-driven installations across multiple sectors.
Electric vehicles represent the largest battery deployment sector, with global EV sales exceeding 15 million units annually. The market has bifurcated clearly: premium vehicles using high-energy-density NMC batteries for maximum range, and mass-market vehicles increasingly adopting LFP for optimal cost-performance balance. Tesla's decision to use LFP in standard-range Model 3 and Model Y vehicles has validated this approach, demonstrating that consumers will accept slightly reduced range for significantly lower costs.
Grid-scale storage has experienced explosive growth, with installations exceeding 20 GW annually. These systems primarily use LFP chemistry, with system costs falling below $200/kWh installed. The business models have evolved beyond simple arbitrage to provide multiple grid services: frequency regulation, voltage support, renewable integration, and grid resilience. California's mandate for 11.5 GW of storage by 2026 has created a template that other jurisdictions are following.
Residential and commercial storage has found its sweet spot in markets with high electricity costs, time-of-use pricing, or unreliable grids. Solar-plus-storage systems have become standard in many markets, with battery costs now representing less than 30% of total system cost. The integration of home batteries with smart home systems and EV charging has created new value propositions beyond simple backup power.
The convergence with automation and intelligent systems has created exciting opportunities. Modern warehouses integrate battery storage with automated systems and warehouse management solutions, optimising both energy consumption and operational efficiency. These smart systems and automation approaches demonstrate how energy storage becomes a crucial enabler of broader technological transformation.
Industrial applications have expanded beyond traditional UPS systems to include mobile robotics, autonomous vehicles, and portable power solutions. The reliability and energy density improvements of modern batteries have enabled new applications in construction, mining, and manufacturing where electrification was previously impractical.
Collaborative Opportunities
The complexity of the modern energy storage ecosystem demands collaboration across traditional industry boundaries. At BatteryMinerals.org, we've witnessed how the most successful projects emerge from partnerships that span the entire value chain—from mining companies working directly with battery manufacturers to recycling companies collaborating with automotive OEMs.
Our platform has become a hub for these connections, facilitating knowledge transfer between upstream and downstream players who historically operated in isolation. Mining engineers share insights with battery scientists, recycling innovators connect with raw material traders, and policy makers engage with industry practitioners. This cross-pollination has accelerated innovation and improved supply chain efficiency.
We're particularly excited about emerging opportunities in recycling and circular economy initiatives. Companies are beginning to design batteries with end-of-life recovery in mind, creating closed-loop systems that reduce dependence on primary mining. These initiatives require unprecedented cooperation between manufacturers, recyclers, and material processors.
Research collaborations are also bearing fruit, with joint projects between universities, government labs, and industry partners advancing both fundamental science and practical applications. Our community provides a platform for identifying research gaps and connecting academic capabilities with commercial needs.

Future Outlook
Looking ahead, several trends will shape the energy storage landscape through the remainder of this decade.
Policy alignment is becoming increasingly sophisticated, with governments recognising that supporting energy storage requires coordinated approaches across mining, manufacturing, deployment, and recycling. The US Inflation Reduction Act, Europe's Critical Raw Materials Act, and China's 14th Five-Year Plan all demonstrate how policy makers are thinking systemically about battery value chains.
Recycling infrastructure will mature rapidly, driven by both economic opportunity and regulatory requirements. The first wave of EV batteries from the early 2010s is approaching end-of-life, creating a growing feedstock for recycling operations. Companies like Redwood Materials and Li-Cycle are scaling operations that could supply 20-30% of battery mineral demand by 2030.
AI-enhanced battery design is accelerating development cycles and optimising performance across multiple parameters simultaneously. Machine learning algorithms are identifying new material combinations, predicting degradation patterns, and optimising charging strategies in ways that would be impossible through traditional methods. This convergence of artificial intelligence and battery technology promises to unlock performance improvements that have been elusive through conventional approaches.
Manufacturing localisation will continue, driven by supply chain resilience concerns and supportive policies. However, this won't simply replicate existing Chinese approaches—new manufacturing technologies, automation, and process innovations will create opportunities for more efficient and sustainable production methods.
The integration of energy storage with other technologies will deepen, creating new value propositions and applications. Smart grids, autonomous vehicles, and renewable energy systems will become increasingly interdependent, with energy storage serving as the crucial link that enables optimisation across these connected systems.
Conclusion
The state of energy storage in 2025 reflects an industry that has moved from experimental to essential. We've solved many of the fundamental technical challenges and are now focused on scaling, optimising, and integrating these solutions into the fabric of modern society.
The opportunities ahead are enormous, but they require continued collaboration across traditional industry boundaries. Success will come to those who understand the entire ecosystem—from the geochemistry of mineral deposits to the algorithms that optimise grid operations.
As we charge ahead into this energy storage future, the foundations we're building today will determine how quickly we can achieve our climate goals and how resilient our energy systems will be in an uncertain world. The journey from raw materials to full-stack batteries represents one of the most significant industrial transformations of our time.
