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?

The World’s Biggest Nuclear Energy Producers
China has grown its nuclear capacity over the last decade, now ranking second on the list of top nuclear energy producers.

Scientists in South Korea recently broke a record in a nuclear fusion experiment. For 48 seconds, they sustained a temperature seven times that of the sun’s core.
But generating commercially viable energy from nuclear fusion still remains more science fiction than reality. Meanwhile, its more reliable sibling, nuclear fission, has been powering our world for many decades.
In this graphic, we visualized the top producers of nuclear energy by their share of the global total, measured in terawatt hours (TWh). Data for this was sourced from the Nuclear Energy Institute, last updated in August 2022.
Which Country Generates the Most Nuclear Energy?
Nuclear energy production in the U.S. is more than twice the amount produced by China (ranked second) and France (ranked third) put together. In total, the U.S. accounts for nearly 30% of global nuclear energy output.
However, nuclear power only accounts for one-fifth of America’s electricity supply. This is in contrast to France, which generates 60% of its electricity from nuclear plants.
Rank | Country | Nuclear Energy Produced (TWh) | % of Total |
---|---|---|---|
1 | 🇺🇸 U.S. | 772 | 29% |
2 | 🇨🇳 China | 383 | 14% |
3 | 🇫🇷 France | 363 | 14% |
4 | 🇷🇺 Russia | 208 | 8% |
5 | 🇰🇷 South Korea | 150 | 6% |
6 | 🇨🇦 Canada | 87 | 3% |
7 | 🇺🇦 Ukraine | 81 | 3% |
8 | 🇩🇪 Germany | 65 | 2% |
9 | 🇯🇵 Japan | 61 | 2% |
10 | 🇪🇸 Spain | 54 | 2% |
11 | 🇸🇪 Sweden | 51 | 2% |
12 | 🇧🇪 Belgium | 48 | 2% |
13 | 🇬🇧 UK | 42 | 2% |
14 | 🇮🇳 India | 40 | 2% |
15 | 🇨🇿 Czech Republic | 29 | 1% |
N/A | 🌐 Other | 219 | 8% |
N/A | 🌍 Total | 2,653 | 100% |
Another highlight is how China has rapidly grown its nuclear energy capabilities in the last decade. Between 2016 and 2021, for example, it increased its share of global nuclear energy output from less than 10% to more than 14%, overtaking France for second place.
On the opposite end, the UK’s share has slipped to 2% over the same time period.
Meanwhile, Ukraine has heavily relied on nuclear energy to power its grid. In March 2022, it lost access to its key Zaporizhzhia Nuclear Power Station after Russian forces wrested control of the facility. With six 1,000 MW reactors, the plant is one of the largest in Europe. It is currently not producing any power, and has been the site of recent drone attacks.
