The Extraordinary Raw Materials in a Tesla Model S
Presented by: Red Cloud Klondike Strike (Equity crowdfunding in mining)
The Tesla Model S is the world’s most-wanted electric car, with 100,000 units already sold as of December 2015.
Critics have lauded the car for its impressive safety rating, range, and design. However, it is also worth considering that it is the incredible raw materials that go into the Tesla Model S that help to make all of these things possible.
Here’s what’s in a Tesla Model S:
Body and Chassis
Bauxite: The Tesla Model S body and chassis are built almost entirely from aluminum, which comes from bauxite ore. Aluminum is lightweight, which helps to maximize the range of the battery beyond that of other EVs. The total amount of aluminum used in the car is 410 lbs (190 kg).
Boron steel: High-strength boron steel is used to reinforce the aluminum at critical safety points. Boron steel is made from iron, boron, coking coal, and other additives.
Titanium: The underbody of the Tesla Model S is made from ultra high-strength titanium, which protects the battery from nearly any roadside force or piercing.
Rare Earth Metals: While Tesla engines and batteries do not use rare earths, most high-end car speakers and other electronics use rare earth elements such as neodymium magnets.
Plastic: Most plastics are made from petrochemicals.
Leather: Leather is derived from animal skin, mainly cowhides .
Silicon: Glass windows and other features are made from silicon.
Carbon fiber and copper wire are also used within the interior for various components.
Bauxite: Aluminum alloy wheels are also made from bauxite ore.
Rubber: Natural rubber comes from rubber trees, but today 70% of US rubber is synthetic, made from petrochemicals.
Copper: Tesla’s high-performance copper rotor motor delivers 300 horsepower and weighs 100 lbs (45.4 kg).
Steel: The stationary piece of the engine, the stator, is made from both copper and steel.
The Tesla battery pack weighs 1,200 lbs (540 kg), which is equal to about 26% of the car’s total weight. This puts the car’s center of gravity a mere 44.5 centimeters off the ground, giving the car unprecedented stability.
The battery itself contains 7,104 lithium-ion battery cells. Here’s what’s in each cell:
Cathode: The Tesla Model S battery cathode uses an NCA formulation with the approximate ratio: 80% nickel, 15% cobalt, and 5% aluminum. Small amounts of lithium are also used in the cathode.
Anode: The negative terminal uses natural or synthetic graphite to hold lithium ions. Small amounts of silicon are also likely used in the anode as well.
Electrolyte: The electrolyte is made of a lithium salt.
Copper and/or aluminum foil is also used in the battery as well.
Note: all numbers above are based on the 85 kWh battery model.
Silver Through the Ages: The Uses of Silver Over Time
The uses of silver span various industries, from renewable energy to jewelry. See how the uses of silver have evolved in this infographic.
Silver is one of the most versatile metals on Earth, with a unique combination of uses both as a precious and industrial metal.
Today, silver’s uses span many modern technologies, including solar panels, electric vehicles, and 5G devices. However, the uses of silver in currency, medicine, art, and jewelry have helped advance civilization, trade, and technology for thousands of years.
The Uses of Silver Over Time
The below infographic from Blackrock Silver takes us on a journey of silver’s uses through time, from the past to the future.
3,000 BC – The Middle Ages
The earliest accounts of silver can be traced to 3,000 BC in modern-day Turkey, where its mining spurred trade in the ancient Aegean and Mediterranean seas. Traders and merchants would use hacksilver—rough-cut pieces of silver—as a medium of exchange for goods and services.
Around 1,200 BC, the Ancient Greeks began refining and minting silver coins from the rich deposits found in the mines of Laurion just outside Athens. By 100 BC, modern-day Spain became the center of silver mining for the Roman Empire while silver bullion traveled along the Asian spice trade routes. By the late 1400s, Spain brought its affinity for silver to the New World where it uncovered the largest deposits of silver in history in the dusty hills of Bolivia.
Besides the uses of silver in commerce, people also recognized silver’s ability to fight bacteria. For instance, wine and food containers were often made out of silver to prevent spoilage. In addition, during breakouts of the Bubonic plague in medieval and renaissance Europe, people ate and drank with silver utensils to protect themselves from disease.
The 1800s – 2000s
New medicinal uses of silver came to light in the 19th and 20th centuries. Surgeons stitched post-operative wounds with silver sutures to reduce inflammation. In the early 1900s, doctors prescribed silver nitrate eyedrops to prevent conjunctivitis in newborn babies. Furthermore, in the 1960s, NASA developed a water purifier that dispensed silver ions to kill bacteria and purify water on its spacecraft.
The Industrial Revolution drove the onset of silver’s industrial applications. Thanks to its high light sensitivity and reflectivity, it became a key ingredient in photographic films, windows, and mirrors. Even today, skyscraper windows are often coated with silver to reflect sunlight and keep interior spaces cool.
The 2000s – Present
The uses of silver have come a long way since hacksilver and utensils, evolving with time and technology.
Silver is the most electrically conductive metal, making it a natural choice for electronic devices. Almost every electronic device with a switch or button contains silver, from smartphones to electric vehicles. Solar panels also utilize silver as a conductive layer in photovoltaic cells to transport and store electricity efficiently.
In addition, it has several medicinal applications that range from treating burn wounds and ulcers to eliminating bacteria in air conditioning systems and clothes.
Silver for the Future
Silver has always been useful to industries and technologies due to its unique properties, from its antibacterial nature to high electrical conductivity. Today, silver is critical for the next generation of renewable energy technologies.
For every age, silver proves its value.
Visualizing 50 Years of Global Steel Production
Global steel production has tripled over the past 50 years, with China’s steel production eclipsing the rest of the world.
Visualizing 50 Years of Global Steel Production
From the bronze age to the iron age, metals have defined eras of human history. If our current era had to be defined similarly, it would undoubtedly be known as the steel age.
Steel is the foundation of our buildings, vehicles, and industries, with its rates of production and consumption often seen as markers for a nation’s development. Today, it is the world’s most commonly used metal and most recycled material, with 1,864 million metric tons of crude steel produced in 2020.
This infographic uses data from the World Steel Association to visualize 50 years of crude steel production, showcasing our world’s unrelenting creation of this essential material.
The State of Steel Production
Global steel production has more than tripled over the past 50 years, despite nations like the U.S. and Russia scaling down their domestic production and relying more on imports. Meanwhile, China and India have consistently grown their production to become the top two steel producing nations.
Below are the world’s current top crude steel producing nations by 2020 production.
|Rank||Country||Steel Production (2020, Mt)|
|#5||🇺🇸 United States||72.7|
|#6||🇰🇷 South Korea||67.1|

Despite its current dominance, China could be preparing to scale back domestic steel production to curb overproduction risks and ensure it can reach carbon neutrality by 2060.
As iron ore and steel prices have skyrocketed in the last year, U.S. demand could soon lessen depending on the Biden administration’s actions. A potential infrastructure bill would bring investment into America’s steel mills to build supply for the future, and any walkbalk on the Trump administration’s 2018 tariffs on imported steel could further soften supply constraints.
Steel’s Secret: Infinite Recyclability
Made up primarily of iron ore, steel is an alloy which also contains less than 2% carbon and 1% manganese and other trace elements. While the defining difference might seem small, steel can be 1,000x stronger than iron.
However, steel’s true strength lies in its infinite recyclability with no loss of quality. No matter the grade or application, steel can always be recycled, with new steel products containing 30% recycled steel on average.
The alloy’s magnetic properties make it easy to recover from waste streams, and nearly 100% of the steel industry’s co-products can be used in other manufacturing or electricity generation.
It’s fitting then that steel makes up essential parts of various sustainable energy technologies:
- The average wind turbine is made of 80% steel on average (140 metric tons).
- Steel is used in the base, pumps, tanks, and heat exchangers of solar power installations.
- Electrical steel is at the heart of the generators and motors of electric and hybrid vehicles.
The Steel Industry’s Future Sustainability
Considering the crucial role steel plays in just about every industry, it’s no wonder that prices are surging to record highs. However, steel producers are thinking about long-term sustainability, and are working to make fossil-fuel-free steel a reality by completely removing coal from the metallurgical process.
While the industry has already cut down the average energy intensity per metric ton produced from 50 gigajoules to 20 gigajoules since the 1960s, steel-producing giants like ArcelorMittal are going further and laying out their plans for carbon-neutral steel production by 2050.
Steel consumption and demand is only set to continue rising as the world’s economy gradually reopens, especially as Rio Tinto’s new development of atomized steel powder could bring about the next evolution in 3D printing.
As the industry continues to innovate in both sustainability and usability, steel will continue to be a vital material across industries that we can infinitely recycle and rely on.
