Tesla’s Origin Story in One Giant Infographic
Priced at $17 per share just seven years ago, the Tesla IPO ended up being a total bargain for anyone lucky enough to get in.
However, this view comes with the benefit of plenty of hindsight – and even Elon Musk would tell you that it wasn’t always obvious that the company would be around in 2017. There were periods of time when layoffs were rampant, the company’s payroll was covered by credit cards, and Tesla was on the brink of bankruptcy.
Rise of Tesla: The History (Part 1 of 3)
Today’s massive infographic comes to us from Global Energy Metals, and it is the first part of our three-part Rise of Tesla Series, which will soon be a definitive source for everything you ever wanted to know about the company.
Part 1 deals with the origin story of the company, challenges faced by the first EVs, the company’s strategy and initial execution, and the Tesla Roadster’s development.
Tesla was initially conceived in 2003 out of the vision of two Silicon Valley engineers, Martin Eberhard and Marc Tarpenning. The partners had just sold their eReader company for $187 million, and were looking for their next big idea.
The infamous “death” of GM’s EV1 electric car that year ended up being a source of inspiration, and the two engineers started looking into ways to reduce the world’s reliance on Middle Eastern oil and to combat climate change.
The electric car pathway was not just better than the other choices that were out there – it was dramatically better.
– Martin Eberhard, Tesla co-founder
The company was bootstrapped until Elon Musk led the $7.5 million Series A round in February 2004 and became the controlling investor. He joined the board of directors as its chairman, and took on operational roles as well.
At this time, JB Straubel – who famously rebuilt an electric golf cart when he was only 14 years old – also joined the company as CTO.
Initial Strategy
Tesla’s initial strategy was to build a high performance sports car first, for a few reasons:
- It would shed the existing stigma around EVs
- Sports cars have higher margins
- Fewer cars would need to be produced
- High-end buyers are less price-sensitive
Instead of building the Tesla Roadster from scratch, the company aimed to combine an existing chassis with an AC induction motor and battery. And so, the company signed a contract with British sports car maker Lotus to use its Elise chassis as a base.
Roadster Debut
The Roadster made its debut at a star-studded launch party in Santa Monica. The 350-strong guestlist of Hollywood celebrities and the press were wowed by the 2-seater sports car with a $100,000 price tag.
This is not your father’s electric car.
– The Washington Post
What the audience didn’t notice?
The Roadsters had many issues that needed to be fixed – these and others would delay Tesla well beyond the planned Summer 2007 delivery date.
The Dark Years
Tesla’s original business plan was built on the idea that the auto industry had changed drastically.
Automakers now focused on core competencies like financing, engine design, sales and marketing, and final assembly – getting the hundreds of individual car parts, like windshield wiper blades or door handles, was actually outsourced.
This was supposed to make it easy for Tesla to get its foot in the door – to focus on the EV aspect and let Lotus do the rest. Instead, the company experienced an “elegance creep” phenomenon. They were able to keep making the car nicer, but it meant customizing individual parts.
Costs spiraled out of control, things got delayed, and the car began to take a very different shape than the Elise. By the time it was said and done, the Tesla Roadster was nothing like its Lotus cousin, sharing only 7% parts by count.
The Revolving Door
During this process, there was a revolving door of CEOs.
2007: Eberhart was forced to resign as CEO in August
2007: Early Tesla investor Michael Marks took the reins temporarily
2007: In November, Ze’ev Drori took over as CEO and President
2008: After less than a year of Drori’s run, Musk stepped in to take over the role in October
At this point, Musk had already invested $55 million in the company, and it was teetering towards bankruptcy.
I’ve got so many chips on the table with Tesla. It just made sense for me to have both hands on the wheel.
– Elon Musk
Some of Musk’s first moves:
- He ended up cutting 25% of the workforce
- He leaned on friends to help cover payroll, week-to-week
- He raised a $40 debt financing round to escape bankruptcy
- He formed a strategic partnership with Daimler AG, which acquired a 10% stake of Tesla for $50 million
- He took a $465 million loan from the U.S. Dept. of Energy (He repaid it back ahead of the deadline)
- He recalled 75% of the Roadsters produced between March 2008 and April 2009
Despite revamping the entire production process – and the company itself – Tesla made it through its most trying time.
The Roadster’s Run
The Roadster wasn’t perfect, but it helped Tesla learn what it meant to be a car company.
It is not just a car, but one of the strongest automotive statements on the road.
– Car and Driver
A total of 2,450 units were produced, and the specs were impressive for an EV. With a top speed of 125 mph and a 0-60 mph time of 3.7 seconds, the Roadster helped dispel many of the myths surrounding electric cars.
Meanwhile, the Roadster’s lithium-ion battery also was the first step forward in an entire battery revolution. The 992 lb (450 kg) battery for the Roadster contained 6,831 lithium ion cells arranged into 11 “sheets” connected in series, and gave the car a range of 244 miles.
With the Roadster, Tesla would not only set itself up for future success, but also the transformation of an entire industry.
This was Part 1 of the Tesla Series. Parts 2 and 3, on Tesla as well as the future vision, will be released in the near future!

Visualized: Inside a Lithium-Ion Battery
Lithium-ion batteries are critical for many modern technologies, from smartphones to smart cities. Here’s how this critical technology works.
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.
