Graphite: An Essential Material in the Battery Supply Chain
The demand for lithium-ion (Li-ion) batteries has skyrocketed in recent years due to the increasing popularity of electric vehicles (EVs) and renewable energy storage systems.
What many people don’t realize, however, is that the key component of these batteries is not just lithium, but also graphite.
Graphite represents almost 50% of the materials needed for batteries by weight, regardless of the chemistry. In Li-ion batteries specifically, graphite makes up the anode, which is the negative electrode responsible for storing and releasing electrons during the charging and discharging process.
To explore just how essential graphite is in the battery supply chain, this infographic sponsored by Northern Graphite dives into how the anode of a Li-ion battery is made.
What is Graphite?
Graphite is a naturally occurring form of carbon that is used in a wide range of industrial applications, including in synthetic diamonds, EV Li-ion batteries, pencils, lubricants, and semiconductor substrates.
It is stable, high-performing, and reusable. While it comes in many different grades and forms, battery-grade graphite falls into one of two classes: natural or synthetic.
Natural graphite is produced by mining naturally occurring mineral deposits. This method produces only one to two kilograms of CO2 emissions per kilogram of graphite.
Synthetic graphite, on the other hand, is produced by the treatment of petroleum coke and coal tar, producing nearly 5 kg of CO2 per kilogram of graphite along with other harmful emissions such as sulfur oxide and nitrogen oxide.
A Closer Look: How Graphite Turns into a Li-ion Battery Anode
The battery anode production process is composed of four overarching steps. These are:
- Mining
- Shaping
- Purifying
- Coating
Each of these stages results in various forms of graphite with different end-uses.
For instance, the micronized graphite that results from the shaping process can be used in plastic additives. On the other hand, only coated spherical purified graphite that went through all four of the above stages can be used in EV Li-ion batteries.
The Graphite Supply Chain
Despite its growing use in the energy transition all around the world, around 70% of the world’s graphite currently comes from China.
With scarce alternatives to be used in batteries, however, achieving supply security in North America is crucial, and it is using more environmentally friendly approaches to graphite processing.
With a lower environmental footprint and lower production costs, natural graphite serves as the anode material for a greener future.

Charted: The Energy Demand of U.S. Data Centers
Data center power needs are projected to triple by 2030.

As the digital economy accelerates and generative AI becomes more deeply embedded in business and daily life, the physical infrastructure supporting these technologies is undergoing a transformative explosion.
In this graphic, we use data from McKinsey to show current and projected energy demand from data centers in the United States. Data is from October 2023.
U.S. Data Centers Could Quadruple Power Demand by 2030
Today, data centers account for roughly 4% of total U.S. electricity consumption. But by 2030, that share is projected to rise to 12%, driven by unprecedented growth in computing power, storage needs, and AI model training.
In fact, U.S. data center energy demand is set to jump from 224 terawatt-hours in 2025 to 606 terawatt-hours in 2030.
Year | Consumption (TWh) | % of Total Power Demand |
---|---|---|
2023 | 147 | 4% |
2024 | 178 | 4% |
2025 | 224 | 5% |
2026 | 292 | 7% |
2027 | 371 | 8% |
2028 | 450 | 9% |
2029 | 513 | 10% |
2030 | 606 | 12% |
Meeting this projected demand could require $500 billion in new data center infrastructure, along with a vast expansion of electricity generation, grid capacity, and water-cooling systems. Generative AI alone could require 50–60 GW of additional infrastructure.
This massive investment would also depend on upgrades in permitting, land use, and supply chain logistics. For example, the lead time to power new data centers in large markets such as Northern Virginia can exceed three years. In some cases, lead times for electrical equipment are two years or more.
A Strain on the U.S. Grid
The U.S. has experienced relatively flat power demand since 2007. Models suggest that this stability could be disrupted in the coming years. Data center growth alone could account for 30–40% of all net-new electricity demand through 2030.
Unlike typical power loads, data center demand is constant, dense, and growing exponentially. Facilities often operate 24/7, with little downtime and minimal flexibility to reduce usage.

Visualizing China’s Battery Recycling Dominance
In 2025, China will hold 78% of pre-treatment and 89% of refining capacity.

Visualizing China’s Battery Recycling Dominance
Battery recycling is expected to become a cornerstone of the global energy transition as electric vehicles (EVs) and other battery-powered technologies become more widespread.
According to exclusive data from Benchmark Mineral Intelligence, China holds a dominant position in both the pre-treatment and refining stages of battery recycling.
Chinese Growing Dominance
Battery recycling involves two major stages. First is pre-treatment, where recycling begins. Scrap batteries are typically shredded and separated to produce a material known as black mass.
The next stage is refining, which processes black mass into valuable lithium-, nickel-, and cobalt-based chemicals for use in battery cathodes.
China’s scale, infrastructure, and early investments in battery supply chains have translated into an outsized advantage in recycling capacity.
As the largest producer and user of lithium ion batteries, the country is expected to process 3.6 million tonnes of scrap batteries in 2025, up from 1.2 million tonnes in 2022. This would account for 78% of global pre-treatment capacity, with total global capacity projected to exceed 4.6 million tonnes.
Region/Tonnes | 2022 | 2023 | 2024 | 2025P |
---|---|---|---|---|
Global | 1.5M | 2.4M | 2.8M | 4.6M |
China | 1.2M | 1.8M | 2.1M | 3.6M |
Asia excl. China | 158K | 231K | 288K | 361K |
Europe | 118K | 133K | 243K | 416K |
North America | 59K | 165K | 129K | 196K |
ROW | 4K | 6K | 6K | 40K |
In second place is the rest of Asia, with 361,000 tonnes, followed by Europe with 416,000 tonnes. While the U.S. attempts to reduce its reliance on China in the mineral sector, North America accounts for just 196,000 tonnes.
The refining stage is even more concentrated.
China’s black mass refining capacity is projected to nearly triple, from 895,000 tonnes in 2022 to 2.5 million tonnes by 2025—representing 89% of global capacity.
Region/Tonnes | 2022 | 2023 | 2024 | 2025P |
---|---|---|---|---|
Global | 960K | 1.4M | 1.7M | 2.8M |
China | 895K | 1.3M | 1.5M | 2.5M |
Asia excl. China | 48K | 101K | 146K | 225K |
Europe | 13K | 23K | 25K | 28K |
North America | 4K | 5K | 5K | 21K |
ROW | 0 | 1K | 1K | 32K |
Refining is critical, as it converts recycled material into high-purity, battery-grade chemicals. The rest of Asia is expected to refine 225,000 tonnes, Europe 28,000 tonnes, and North America only 21,000 tonnes. Between 2022 and 2025, China’s refining capacity is projected to grow by 179%, while North America’s is expected to surge by 425%—albeit from a much smaller base.
As global demand for EVs and battery storage rises, countries looking to build domestic recycling infrastructure must accelerate investment to reduce dependence on Chinese supply chains.
