Tesla has once again tapped another Canadian battery startup in efforts to develop and manufacture high-quality, dependable, and long-lasting electric vehicle batteries. Documents of the transaction suggest Tesla acquired three separate patent applications from Canada’s Springpower International for only $3.00.
Tesla reportedly purchased several patent applications from Springpower International, a small, Canadian company that was established in 2010. The company’s website has gone nearly blank after the reports, only giving information to those who inquire through Springpower’s email.
Interestingly, Tesla purchased the patents just two weeks before the Battery Day event that was held in September 2020, TechCrunch reports. The site found the patent transaction records, which show that Tesla purchased several applications for a total of $3. The document states, “Therefore, for $3.00 and good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows…” The preceding words outline the transfer of patents from Springpower International Inc. to Tesla, Inc.
The three patents that were transferred to Tesla are “Innovative Process to Produce Cathode Materials for Rechargeable Lithium-Ion Batteries” (US 62/899,677), “Process for Recovering Materials from Spent Rechargeable Lithium Batteries” (US 62/951,735), and “Method to Produce Cathode Materials for Li-Ion Batteries” (US 62/652,516). The patents are similar to the processes CEO Elon Musk, and Senior VP of Engineering Drew Baglino outlined during the Battery Day event and could translate to Tesla’s future methods for battery manufacturing.
Tesla unveiled the new 4680 battery cell at Battery Day. Tesla plans to make the cell in-house, but it will also be produced by several of the automaker’s suppliers, like LG Chem and Panasonic. The new cells offer exponentially more energy, six times the power, and more range as Tesla attempts to expand its production efforts to help EVs reach price parity with gas-powered cars.

Additionally, it seems that several Springpower employees have also transitioned to roles with Tesla. One is Yang Liu, a Senior Research Engineer for Tesla, who previously worked for Springpower as a Research and Development Chemist. He made the switch to Tesla in September when the Battery Day event took place. Amrit Bhogan, a Cell Engineering Technician at Tesla, also transitioned to the Silicon Valley-based electric carmaker in September after previously working for Springpower as a Chemical Technologist.
Tesla has previously used Canadian battery companies to advance its lithium-ion cell technology. Tesla acquired Hibar Systems, a company that was based in Ontario and produced battery cells. The acquisition of Hibar by Tesla followed the automaker’s purchase of Maxwell Technologies, a California-based producer of ultracapacitors and batteries, in May 2019.
Tesla has also utilized the expertise of Jeff Dahn, a battery researcher at Canada’s Dalhousie University, along with his cell research team at the institution. Dahn and Tesla recently extended their partnership in a five-year extension.

Tesla Megapacks chosen for 548 MWh energy storage project in Japan
Tesla plans to supply over 100 Megapack units to support a large stationary storage project in Japan, making it one of the country’s largest energy storage facilities.

Tesla’s Megapack grid-scale batteries have been selected to back an energy storage project in Japan, coming as the latest of the company’s continued deployment of the hardware.
As detailed in a report from Nikkei this week, Tesla plans to supply 142 Megapack units to support a 548 MWh storage project in Japan, set to become one of the country’s largest energy storage facilities. The project is being overseen by financial firm Orix, and it will be located at a facility Maibara in central Japan’s Shiga prefecture, and it aims to come online in early 2027.
The deal is just the latest of several Megapack deployments over the past few years, as the company continues to ramp production of the units. Tesla currently produces the Megapack at a facility in Lathrop, California, though the company also recently completed construction on its second so-called “Megafactory” in Shanghai China and is expected to begin production in the coming weeks.

Tesla’s production of the Megapack has been ramping up at the Lathrop facility since initially opening in 2022, and both this site and the Shanghai Megafactory are aiming to eventually reach a volume production of 10,000 Megapack units per year. The company surpassed its 10,000th Megapack unit produced at Lathrop in November.
During Tesla’s Q4 earnings call last week, CEO Elon Musk also said that the company is looking to construct a third Megafactory, though he did not disclose where.
Last year, Tesla Energy also had record deployments of its Megapack and Powerwall home batteries with a total of 31.4 GWh of energy products deployed for a 114-percent increase from 2023.
Other recently deployed or announced Megapack projects include a massive 600 MW/1,600 MWh facility in Melbourne, a 75 MW/300 MWh energy storage site in Belgium, and a 228 MW/912 MWh storage project in Chile, along with many others still.

Elon Musk responds to Ontario canceling $100M Starlink deal amid tariff drama
Ontario Premier Doug Ford said, opens new tab on February 3 that he was “ripping up” his province’s CA$100 million agreement with Starlink in response to the U.S. imposing tariffs on Canadian goods.

Elon Musk company SpaceX is set to lose a $100 million deal with the Canadian province of Ontario following a response to the Trump administration’s decision to apply 25 percent tariffs to the country.
Starlink, a satellite-based internet service launched by the Musk entity SpaceX, will lose a $100 million deal it had with Ontario, Premier Doug Ford announced today.
Starting today and until U.S. tariffs are removed, Ontario is banning American companies from provincial contracts.
Every year, the Ontario government and its agencies spend $30 billion on procurement, alongside our $200 billion plan to build Ontario. U.S.-based businesses will…

Ford said on X today that Ontario is banning American companies from provincial contracts:
“We’ll be ripping up the province’s contract with Starlink. Ontario won’t do business with people hellbent on destroying our economy. Canada didn’t start this fight with the U.S., but you better believe we’re ready to win it.”
It is a blow to the citizens of the province more than anything, as the Starlink internet constellation has provided people in rural areas across the globe stable and reliable access for several years.
Musk responded in simple terms, stating, “Oh well.”
Oh well https://t.co/1jpMu55T6s
— Elon Musk (@elonmusk) February 3, 2025
It seems Musk is less than enthused about the fact that Starlink is being eliminated from the province, but it does not seem like all that big of a blow either.
As previously mentioned, this impacts citizens more than Starlink itself, which has established itself as a main player in reliable internet access. Starlink has signed several contracts with various airlines and maritime companies.
It is also expanding to new territories across the globe on an almost daily basis.
With Mexico already working to avoid the tariff situation with the United States, it will be interesting to see if Canada does the same.
The two have shared a pleasant relationship, but President Trump is putting his foot down in terms of what comes across the border, which could impact Americans in the short term.
