What’s Inside a Lithium-Ion Battery?
Winning the Nobel Prize for Chemistry in 2019, the lithium-ion battery has become ubiquitous and today powers nearly everything, from smartphones to electric vehicles.
In this graphic, we partnered with EnergyX to find out how these important pieces of technology work.
Looking Inside
Lithium-ion batteries have different standards in various regions, namely NMC/NMCA in Europe and North America and LFP in China. The former has a higher energy density, while the latter has a lower cost.
Here is the average mineral composition of a lithium-ion battery, after taking account those two main cathode types:
| Material | % of Construction |
|---|---|
| Nickel (Ni) | 4% |
| Manganese (Mn) | 5% |
| Lithium (Li) | 7% |
| Cobalt (Co) | 7% |
| Copper (Cu) | 10% |
| Aluminum (Al) | 15% |
| Graphite (C) | 16% |
| Other Materials | 36% |
The percentage of lithium found in a battery is expressed as the percentage of lithium carbonate equivalent (LCE) the battery contains. On average, that is equal to 1g of lithium metal for every 5.17g of LCE.
How Do They Work?
Lithium-ion batteries work by collecting current and feeding it into the battery during charging. Normally, a graphite anode attracts lithium ions and holds them as a charge. But interestingly, recent research shows that battery energy density can nearly double when replacing graphite with a thin layer of pure lithium.
When discharging, the cathode attracts the stored lithium ions and funnels them to another current collector. The circuit can react as both the anode and cathode are prevented from touching and are suspended in a medium that allows the ions to flow easily.
Powering Tomorrow
Despite making up only 7% of a battery’s weight on average, lithium is so critical for manufacturing lithium-ion batteries that the U.S. Geological Survey has classified it as one of 35 minerals vital to the U.S. economy.
This means refining lithium more effectively is critical to meeting the demand for next-generation lithium-ion batteries.
EnergyX is powering the clean energy transition with the next generation of lithium metal batteries with longer cycle life, greater energy density, and faster charging times.

Ranked: The Top 10 EV Battery Manufacturers in 2023
Asia dominates this ranking of the world’s largest EV battery manufacturers in 2023.
The Top 10 EV Battery Manufacturers in 2023

Despite efforts from the U.S. and EU to secure local domestic supply, all major EV battery manufacturers remain based in Asia.
In this graphic we rank the top 10 EV battery manufacturers by total battery deployment (measured in megawatt-hours) in 2023. The data is from EV Volumes.
Chinese Dominance
Contemporary Amperex Technology Co. Limited (CATL) has swiftly risen in less than a decade to claim the title of the largest global battery group.
The Chinese company now has a 34% share of the market and supplies batteries to a range of made-in-China vehicles, including the Tesla Model Y, SAIC’s MG4/Mulan, and Li Auto models.
| Company | Country | 2023 Production (megawatt-hour) | Share of Total Production |
|---|---|---|---|
| CATL | 🇨🇳China | 242,700 | 34% |
| BYD | 🇨🇳China | 115,917 | 16% |
| LG Energy Solution | 🇰🇷Korea | 108,487 | 15% |
| Panasonic | 🇯🇵Japan | 56,560 | 8% |
| SK On | 🇰🇷Korea | 40,711 | 6% |
| Samsung SDI | 🇰🇷Korea | 35,703 | 5% |
| CALB | 🇨🇳China | 23,493 | 3% |
| Farasis Energy | 🇨🇳China | 16,527 | 2% |
| Envision AESC | 🇨🇳China | 8,342 | 1% |
| Sunwoda | 🇨🇳China | 6,979 | 1% |
| Other | - | 56,040 | 8% |
In 2023, BYD surpassed LG Energy Solution to claim second place. This was driven by demand from its own models and growth in third-party deals, including providing batteries for the made-in-Germany Tesla Model Y, Toyota bZ3, Changan UNI-V, Venucia V-Online, as well as several Haval and FAW models.
The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment.
Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year. With its main client, Tesla, now effectively sourcing batteries from multiple suppliers, the Japanese battery maker seems to be losing its competitive edge in the industry.
Overall, the global EV battery market size is projected to grow from $49 billion in 2022 to $98 billion by 2029, according to Fortune Business Insights.

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.
| Rank | Project Name | LCE, million metric tons (est.) |
|---|---|---|
| 1 | McDermitt Caldera | 21.5 |
| 2 | Thacker Pass | 19.1 |
| 3 | Tonopah Flats | 18.0 |
| 4 | TLC Lithium | 10.7 |
| 5 | Clayton Valley (Century Lithium) | 6.3 |
| 6 | Zeus Lithium | 6.3 |
| 7 | Rhyolite Ridge | 3.4 |
| 8 | Arkansas Smackover (Phase 1A) | 2.8 |
| 9 | Basin Project | 2.2 |
| 10 | McGee Deposit | 2.1 |
| 11 | Arkansas Smackover (South West) | 1.8 |
| 12 | Clayton Valley (Lithium-X, Pure Energy) | 0.8 |
| 13 | Big Sandy | 0.3 |
| 14 | Imperial Valley/Salton Sea | 0.3 |
U.S. Lithium Opportunities, By State
U.S. lithium projects mainly exist in western states, with comparatively minor opportunities in central or eastern states.
| State | LCE, million metric tons (est.) |
|---|---|
| Nevada | 88.2 |
| Arkansas | 4.6 |
| Arizona | 2.5 |
| California | 0.3 |
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.
