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:

  1. Mining
  2. Shaping
  3. Purifying
  4. 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.

White Gold: Mapping U.S. Lithium Mines

In this graphic, Visual Capitalist partnerered with EnergyX to explore the size and location of U.S. lithium mines.

White Gold: Mapping U.S. Lithium Mines

The U.S. doubled imports of lithium-ion batteries for the third consecutive year in 2022, and with EV demand growing yearly, U.S. lithium mines must ramp up production or rely on other nations for their supply of refined lithium.

To determine if the domestic U.S. lithium opportunity can meet demand, we partnered with EnergyX to determine how much lithium sits within U.S. borders.

U.S. Lithium Projects

The most crucial measure of a lithium mine’s potential is the quantity that can be extracted from the source.

For each lithium resource, the potential volume of lithium carbonate equivalent (LCE) was calculated with a ratio of one metric ton of lithium producing 5.32 metric tons of LCE. Cumulatively, existing U.S. lithium projects contain 94.8 million metric tons of LCE.

13Big Sandy0.3

U.S. Lithium Opportunities, By State

U.S. lithium projects mainly exist in western states, with comparatively minor opportunities in central or eastern states.

StateLCE, million metric tons (est.)
Nevada88.2
Arkansas4.6
Arizona2.5
California0.3

Currently, the U.S. is sitting on a wealth of lithium that it is underutilizing. For context, in 2022, the U.S. only produced about 5,000 metric tons of LCE and imported a projected 19,000 metric tons of LCE, showing that the demand for the mineral is healthy.

The Next Gold Rush?

U.S. lithium companies have the opportunity to become global leaders in lithium production and accelerate the transition to sustainable energy sources. This is particularly important as the demand for lithium is increasing every year.

EnergyX is on a mission to meet U.S. lithium demands using groundbreaking technology that can extract 300% more lithium from a source than traditional methods.

You can take advantage of this opportunity by investing in EnergyX and joining other significant players like GM in becoming a shareholder.

Will Direct Lithium Extraction Disrupt the $90B Lithium Market?

Visual Capitalist and EnergyX explore how direct lithium extraction could disrupt the $90B lithium industry.

Will Direct Lithium Extraction Disrupt the $90B Lithium Market?

Current lithium extraction and refinement methods are outdated, often harmful to the environment, and ultimately inefficient. So much so that by 2030, lithium demand will outstrip supply by a projected 1.42 million metric tons. But there is a solution: Direct lithium extraction (DLE).

For this graphic, we partnered with EnergyX to try to understand how DLE could help meet global lithium demands and change an industry that is critical to the clean energy transition.

The Lithium Problem

Lithium is crucial to many renewable energy technologies because it is this element that allows EV batteries to react. In fact, it’s so important that projections show the lithium industry growing from $22.2B in 2023 to nearly $90B by 2030.

But even with this incredible growth, as you can see from the table, refined lithium production will need to increase 86.5% over and above current projections.

2022 (million metric tons)2030P (million metric tons)
Lithium Carbonate Demand0.461.21
Lithium Hydroxide Demand0.181.54
Lithium Metal Demand00.22
Lithium Mineral Demand0.070.09
Total Demand0.713.06
Total Supply0.751.64

The Solution: Direct Lithium Extraction

DLE is a process that uses a combination of solvent extraction, membranes, or adsorbents to extract and then refine lithium directly from its source. LiTASTM, the proprietary DLE technology developed by EnergyX, can recover an incredible 300% more lithium per ton than existing processes, making it the perfect tool to help meet lithium demands.

Additionally, LiTASTM can refine lithium at the lowest cost per unit volume directly from brine, an essential step in meeting tomorrow’s lithium demand and manufacturing next-generation batteries, while significantly reducing the footprint left by lithium mining.
