As electric vehicle (EV) battery prices keep dropping, the global supply of EVs and demand for their batteries are ramping up.
Since 2010, the average price of a lithium-ion (Li-ion) EV battery pack has fallen from $1,200 per kilowatt-hour (kWh) to just $132/kWh in 2021.
Inside each EV battery pack are multiple interconnected modules made up of tens to hundreds of rechargeable Li-ion cells. Collectively, these cells make up roughly 77% of the total cost of an average battery pack, or about $101/kWh.
So, what drives the cost of these individual battery cells?
The Cost of a Battery Cell
According to data from BloombergNEF, the cost of each cell’s cathode adds up to more than half of the overall cell cost.
EV Battery Cell Component | % of Cell Cost |
---|---|
Cathode | 51% |
Manufacturing and depreciation | 24% |
Anode | 12% |
Separator | 7% |
Electrolyte | 4% |
Housing and other materials | 3% |
Percentages may not add to 100% due to rounding.
Why Are Cathodes so Expensive?
The cathode is the positively charged electrode of the battery. When a battery is discharged, both electrons and positively-charged molecules (the eponymous lithium ions) flow from the anode to the cathode, which stores both until the battery is charged again.
That means that cathodes effectively determine the performance, range, and thermal safety of a battery, and therefore of an EV itself, making them one of the most important components.
They are composed of various metals (in refined forms) depending on cell chemistry, typically including lithium and nickel. Common cathode compositions in modern use include:
- Lithium iron phosphate (LFP)
- Lithium nickel manganese cobalt (NMC)
- Lithium nickel cobalt aluminum oxide (NCA)
The battery metals that make up the cathode are in high demand, with automakers like Tesla rushing to secure supplies as EV sales charge ahead. In fact, the commodities in the cathode, along with those in other parts of the cell, account for roughly 40% of the overall cell cost.
Other EV Battery Cell Components
Components outside of the cathode make up the other 49% of a cell’s cost.
The manufacturing process, which involves producing the electrodes, assembling the different components, and finishing the cell, makes up 24% of the total cost.
The anode is another significant component of the battery, and it makes up 12% of the total cost—around one-fourth of the cathode’s share. The anode in a Li-ion cell is typically made of natural or synthetic graphite, which tends to be less expensive than other battery commodities.
Although battery costs have been declining since 2010, the recent surge in prices of key battery metals like lithium has cast a shadow of doubt over their future. How will EV battery prices evolve going forward?

Energy independence is top of mind for many nations as Russia’s invasion of Ukraine has prompted sanctions and bans against Russian coal and crude oil imports.
Despite being the world’s largest oil producer, in 2021 the U.S. still imported more than 3 billion barrels of crude oil and petroleum products, equal to 43% of the country’s consumption.
This visualization uses data from the Energy Information Administration (EIA) to compare U.S. crude oil and refined product imports with domestic crude oil production, and breaks down which countries the U.S. imported its oil from in 2021.
U.S. Crude Oil Imports, by Country
The U.S. imports more than 8 million barrels of petroleum products a day from other nations, making it the world’s second-largest importer of crude oil behind China.
America’s northern neighbor, Canada, is the largest source of petroleum imports at 1.58 billion barrels in 2021. These made up more than 51% of U.S. petroleum imports, and when counting only crude oil imports, Canada’s share rises to 62%.
Rank | Country | U.S. Oil Imports (2021, in barrels) | Share |
---|---|---|---|
#1 | 🇨🇦 Canada | 1,584 million | 51.3% |
#2 | 🇲🇽 Mexico | 259 million | 8.4% |
#3 | 🇷🇺 Russia | 254 million | 7.9% |
#4 | 🇸🇦 Saudi Arabia | 156 million | 5.1% |
#5 | 🇨🇴 Colombia | 74 million | 2.4% |
#6 | 🇪🇨 Ecuador | 61 million | 2.0% |
#7 | 🇮🇶 Iraq | 57 million | 1.9% |
#8 | 🇧🇷 Brazil | 52 million | 1.7% |
#9 | 🇰🇷 South Korea | 48 million | 1.6% |
#10 | 🇳🇱 Netherlands | 46 million | 1.5% |
#11 | 🇳🇬 Nigeria | 45 million | 1.5% |
Other countries | 459 million | 14.7% | |
Total | 3,091 million | 100.0% |
The second-largest contributor to U.S. petroleum imports was another neighbor, Mexico, with 259 million barrels imported in 2021—making up a bit more than 8% of U.S. petroleum imports.
Russia was the third-largest exporter of crude oil and petroleum products to the U.S. in 2021, with their 254 million barrels accounting for almost 8% of total imports.
U.S. Crude Oil and Petroleum Imports from OPEC and OPEC+
Only about 11% of U.S. crude oil and petroleum product imports come from OPEC nations, with another 16.3% coming from OPEC+ members.
While imports from OPEC and OPEC+ members make up more than a quarter of America’s total petroleum imports, this share is fairly small when considering OPEC members currently control nearly 80% of the world’s oil reserves.
Which Countries are Part of OPEC and OPEC-Plus?
The Organization of Petroleum Exporting Countries (OPEC) is a group of 13 petroleum producing nations that formed in 1960 to provide steady prices and supply distribution of crude oil and petroleum products.
In 2016, OPEC-plus was formed with additional oil-exporting nations in order to better control global oil supply and markets in response to a deluge of U.S. shale supply hitting the markets at that time.
OPEC members:
- 🇮🇷 Iran*
- 🇮🇶 Iraq*
- 🇰🇼 Kuwait*
- 🇸🇦 Saudi Arabia*
- 🇻🇪 Venezuela*
- 🇩🇿 Algeria
- 🇦🇴 Angola
- 🇬🇶 Equatorial Guinea
- 🇬🇦 Gabon
- 🇱🇾 Libya
- 🇳🇬 Nigeria
- 🇨🇩 Republic of the Congo
- 🇦🇪 United Arab Emirates
* Founding members
OPEC+ members:
- 🇷🇺 Russia
- 🇲🇽 Mexico
- 🇰🇿 Kazakhstan
- 🇲🇾 Malaysia
- 🇦🇿 Azerbaijan
- 🇧🇭 Bahrain
- 🇧🇳 Brunei
- 🇴🇲 Oman
- 🇸🇩 Sudan
- 🇸🇸 South Sudan
Although OPEC and OPEC+ members supply a significant part of U.S. crude oil and petroleum imports, America has avoided overdependence on the group by instead building strong ties with neighboring exporters Canada and Mexico.
Crude Oil Imports Capitalize on U.S. Refineries
While the U.S. has been a net exporter of crude oil and petroleum products the past two years, exporting 3.15 billion barrels while importing 3.09 billion barrels in 2021, crude oil-only trade tells a different story.
In terms of just crude oil trade, the U.S. was a significant net importer, with 2.23 billion barrels of crude oil imports and only 1.08 billion barrels of crude oil exports. But with the U.S. being the world’s largest crude oil producer, why is this?
As noted earlier, neighboring Canada makes up larger shares of U.S. crude oil imports compared to crude oil and petroleum product imports. Similarly, Mexico reaches 10% of America’s crude oil imports when excluding petroleum products.
Maximizing imports from neighboring countries makes sense on multiple fronts for all parties due to lower transportation costs and risks, and it’s no surprise Canada and Mexico are providing large shares of just crude oil as well. With such a large collection of oil refineries across the border, it’s ultimately more cost-efficient for Canada and Mexico to tap into U.S. oil refining rather than refining domestically.
In turn, Mexico is the largest importer of U.S. produced gasoline and diesel fuel, and Canada is the third-largest importer of American-produced refined petroleum products.
Replacing Russian Crude Oil Imports
While Russia only makes up 8% of American petroleum product imports, their 254 million barrels will need to be replaced as both countries ceased trading soon after Russia’s invasion of Ukraine.
In an effort to curb rising oil and gasoline prices, in March President Joe Biden announced the release of up to 180 million barrels from the U.S. Strategic Petroleum Reserves. Other IEA nations are also releasing emergency oil reserves in an attempt to curb rising prices at the pump and volatility in the oil market.
While the U.S. and the rest of the world are still managing the short-term solutions to this oil supply gap, the long-term solution is complex and has various moving parts. From ramping up domestic oil production to replacing oil demand with other cleaner energy solutions, oil trade and imports will remain a vital part of America’s energy supply.

Wind and solar generate over a tenth of the world’s electricity. Taken together, they are the fourth-largest source of electricity, behind coal, gas, and hydro.
This infographic based on data from Ember shows the rise of electricity from these two clean sources over the last decade.
Europe Leads in Wind and Solar
Wind and solar generated 10.3% of global electricity for the first time in 2021, rising from 9.3% in 2020, and doubling their share compared to 2015 when the Paris Climate Agreement was signed.
In fact, 50 countries (26%) generated over a tenth of their electricity from wind and solar in 2021, with seven countries hitting this landmark for the first time: China, Japan, Mongolia, Vietnam, Argentina, Hungary, and El Salvador.
Denmark and Uruguay achieved 52% and 47% respectively, leading the way in technology for high renewable grid integration.
Rank | Top Countries | Solar/Wind Power Share |
---|---|---|
#1 | 🇩🇰 Denmark | 51.9% |
#2 | 🇺🇾 Uruguay | 46.7% |
#3 | 🇱🇺 Luxembourg | 43.4% |
#4 | 🇱🇹 Lithuania | 36.9% |
#5 | 🇪🇸 Spain | 32.9% |
#6 | 🇮🇪 Ireland | 32.9% |
#7 | 🇵🇹 Portugal | 31.5% |
#8 | 🇩🇪 Germany | 28.8% |
#9 | 🇬🇷 Greece | 28.7% |
#10 | 🇬🇧 United Kingdom | 25.2% |
From a regional perspective, Europe leads with nine of the top 10 countries. On the flipside, the Middle East and Africa have the fewest countries reaching the 10% threshold.
Further Renewables Growth Needed to meet Global Climate Goals
The electricity sector was the highest greenhouse gas emitting sector in 2020.
According to the International Energy Agency (IEA), the sector needs to hit net zero globally by 2040 to achieve the Paris Agreement’s goals of limiting global heating to 1.5 degrees. And to hit that goal, wind and solar power need to grow at nearly a 20% clip each year to 2030.
Despite the record rise in renewables, solar and wind electricity generation growth currently doesn’t meet the required marks to reach the Paris Agreement’s goals.
In fact, when the world faced an unprecedented surge in electricity demand in 2021, only 29% of the global rise in electricity demand was met with solar and wind.
Transition Underway
Even as emissions from the electricity sector are at an all-time high, there are signs that the global electricity transition is underway.
Governments like the U.S., Germany, UK, and Canada are planning to increase their share of clean electricity within the next decade and a half. Investments are also coming from the private sector, with companies like Amazon and Apple extending their positions on renewable energy to become some of the biggest buyers overall.
More wind and solar are being added to grids than ever, with renewables expected to provide the majority of clean electricity needed to phase out fossil fuels.
