Which lithium companies supply Tesla?

Tesla has deals with multiple lithium suppliers, some that are already producers and some that are juniors developing lithium projects.

At the end of 2021, Tesla inked a three-year lithium supply deal with top lithium producer Ganfeng Lithium (OTC Pink:GNENF,SZSE:002460), and the Chinese company began providing products to Tesla starting in 2022. Major miner Arcadium Lithium (NYSE:ALTM,ASX:LTM), which is set to be acquired by Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO) also has supply contracts in place with the EV maker.

China’s Sichuan Yahua Industrial Group (SZSE:002497) agreed to supply battery-grade lithium hydroxide to Tesla through 2030. Under a new, separate agreement finalized in June 2024, Yahua is set to supply Tesla with an unspecified amount of lithium carbonate between 2025 and 2027, with the option to extend the contract by another year.

Tesla also holds deals with junior miners for production that is yet to come on stream. Liontown Resources (ASX:LTR,OTC Pink:LINRF) is set to supply Tesla with lithium spodumene concentrate from its AU$473 million Kathleen Valley project. The deal is for an initial five year period set to begin this year, and production began in July 2024.The company expects to reach nameplate capacity in calendar Q1 2025.

In January 2023, Tesla amended its agreement with Piedmont Lithium (ASX:PLL,NASDAQ:PLL), which now supplies the US automaker with spodumene concentrate from its North American Lithium operation, a joint venture with Sayona Mining (ASX:SYA,OTCQB:SYAXF). The deal is in place through the end of 2025.

Even though Tesla has secured lithium from all these companies, the EV supply chain is a bit more complex than just buying lithium directly from miners. Tesla also works with battery makers, such as Panasonic (OTC Pink:PCRFF,TSE:6752) and CATL (SZSE:300750), which themselves work with other chemical companies that secure their own lithium deals.

What are Tesla batteries made of?

Tesla vehicles use several different battery cathodes, including nickel-cobalt-aluminum (NCA) cathodes and lithium-iron-phosphate (LFP) cathodes.

Tesla is known for using NCA cathodes developed by Japanese company Panasonic. This type of cathode has higher energy density and is a low-cobalt option, but has been less adopted by the industry compared to the widely used nickel-cobalt-manganese (NCM) cathodes. Aside from that, South Korea's LG Energy Solutions (KRX:373220) supplies Tesla with batteries using nickel-cobalt-manganese-aluminum (NCMA) cathodes.

As mentioned, it wasn’t just lithium that saw prices climb in 2021 — cobalt doubled in price that same year, and although it has declined since then, the battery metal remains essential for many EV batteries. Most cobalt mining takes place in the Democratic Republic of Congo, which is often associated with child labor and human rights abuses, fueling concerns over long-term supply.

That said, not all Tesla’s batteries contain cobalt. In 2021, Tesla said that for its standard-range vehicles it would be changing to lithium-iron-phosphate (LFP) cathodes, which are cobalt- and nickel-free. At the time, the company was already making vehicles with LFP chemistry at its factory in Shanghai, which supplies markets in China, the Asia-Pacific region and Europe.

In April 2023, Tesla announced that it planned to use this type of cathode chemistry for its short-range heavy electric trucks, which it calls "semi light." The company is also looking to use LFP batteries in its mid-sized vehicles.

At the top of this year, Tesla made moves to produce LFP batteries at its Sparks, Nevada, battery facility in reaction to the Biden Administration's new regulations on battery materials sourcing, especially on those sourced from China. Reuters reports Tesla battery supplier CATL will sell idle equipment to the car maker for use at the plant, which will have an initial capacity of about 10 gigawatt hours.

What company makes Tesla’s batteries?

Tesla works with multiple battery suppliers, including Panasonic, its longtime partner, as well as LG Energy Solutions, the second largest battery supplier in the world. They supply the EV maker with cells containing nickel and cobalt.

China's CATL has been supplying LFP batteries to Tesla for cars made at its Shanghai plant since 2020. It’s also been reported that BYD Company (OTC Pink:BYDDF,SZSE:002594) is supplying Tesla with the Blade battery — a less bulky LFP battery — which the car manufacturer has used in some of its models in Europe. Additionally, BYD is set to work with Tesla on its battery energy storage systems (BESS) in China, with a plan to supply 20 percent of Tesla's anticipated BESS manufacturing capacity, with CATL expected to cover 80 percent. The factory will use the companies' LFP batteries.

How much lithium is in a Tesla battery?

How much lithium do Tesla batteries actually contain? That question is tricky because many factors are at play. Typically, it depends on battery chemistry, as demonstrated by the chart below, as well as battery size.

For example, the standard Tesla Model S contains about 138 pounds, or 62.6 kilograms, of lithium. It is powered by a NCA battery, which has a weight of 1,200 pounds or 544 kilograms.

The amount of lithium in a Tesla battery can also vary based on model and year as the battery chemistries and weights are often changing with each new iteration.

Back in 2016, Musk said batteries don't require as much lithium as they do nickel or graphite — he described lithium as "the salt in your salad." As the chart below shows, the metal only makes up about a 10th of the materials in each battery.

Will Tesla buy a lithium mine?

For carmakers, securing lithium supply to meet their electrification goals is becoming a challenge, which is why the question of whether they will become miners in the future continues to come up.

But mining lithium is not easy, and despite speculation, it's hard to imagine an automaker being involved in it, SQM’s (NYSE:SQM) Felipe Smith said. “You have to build a learning curve — the resources are all different, there are many challenges in terms of technology — to reach a consistent quality at a reasonable cost,” he noted. “So it's difficult to see that an original equipment manufacturer (OEM), which has a completely different focus, will really engage into these challenges of producing.”

Even so, OEMs are coming to the realization that they might need to build up EV supply chains from scratch after the capital markets' failure to step up, Benchmark Mineral Intelligence’s Simon Moores believes. Furthermore, automotive OEMs that are making EVs will in effect have to become miners.

“I don't mean actual miners, but they are going to have to start buying 25 percent of these mines if they want to guarantee supply — paper contracts won't be enough,” he said.

However, last year Musk made it clear to investors that Tesla is more focused on developing its lithium refining capabilities, rather than getting into the mining game.

Where is Tesla's lithium refinery?

Tesla broke ground on its in-house Texas lithium refinery in the greater Corpos Christi area of the state last year. Tesla's lithium refinery capacity is expected to produce 50 GWh of battery-grade lithium per year. Musk said in late 2023 that construction of the lithium refinery would be completed in 2024, followed by full production in 2025.
