Battery Price Declines Could Soon Reverse |
Hello Hyperdrivers, James Frith here. I wanted to follow up on a topic I first raised in September — battery costs. BloombergNEF has just published the 2021 battery price survey, one of the most important pieces of research we carry out annually.
The key takeaway: On a volume-weighted average basis across the battery industry, prices fell to $132 per kilowatt-hour in 2021. This is down from $140/kWh in 2020 (in real 2021 dollars). The 6% drop isn’t as drastic as the 9% decline we had forecast last year.
Why are this year’s prices higher than expected? The cost of raw materials used in the cathode — lithium, cobalt and nickel — and other key components including the electrolyte have risen this year, putting more pressure on the industry. The increases have been more prominent in the second half of 2021, and even led to Chinese battery manufacturer BYD announcing a 20% battery price increase in November.
The results aren’t as bad as I had feared when I previewed the early findings in September. There are four reasons behind this. First, prices for raw materials and components were relatively low in the first half of the year. This meant that for the first six months of 2021, battery prices were lower than they were in 2020, helping the yearly average to fall.
Second, low-cost lithium iron phosphate (LFP) batteries have been used more in 2021, in both the passenger EV and stationary storage sector. Despite the increase in the price of LFP cells in China in the second half of the year, the average price of these cells in the country is now the same as the average price of high-performing nickel-based cells in the first half, at around $100/kWh. Again, higher adoption of these low-cost batteries has helped to bring the average price down.
Third, when using nickel-based cells, automakers have more widely adopted cathode chemistries that reduce the amount of expensive cobalt used, such as NMC (811). This resulted in lower average NMC prices in the first half of the year, helping to reduce some of the impacts of higher raw material costs in the second half.
Finally, when automakers place large battery orders, they increasingly use contracts that link raw material costs to a commodity index. These prices are normally reviewed on a quarterly basis, and use a price averaged over three months trailing the quarter by a month. This means that prices in the fourth quarter of this year would use an average price from June, July and August. Many automakers won’t feel the hit from the huge lithium price rise seen in September and October until the first quarter of 2022.
We expect prices next year will be $3/kWh higher than 2021 prices on a nominal basis. This would mark the first price increase that the battery industry has seen since we began tracking these prices in 2012. Inflation also will affect the outcome for 2022. Once adjusted for real 2022 dollars, we could still see prices fall.
When I start talking about battery prices, I inevitably get a bunch of folks saying that these prices are unobtainable and unrealistic. However, this really depends on the sector you are working in and how big your order volumes are. Automakers with annual orders in the tens of gigawatt-hours are able to negotiate more competitive pricing. In 2021, battery-pack pricing reported to BNEF ranged from $85/kWh to $546/kWh. Low-volume, niche applications came in at the top of the range.
In sectors like stationary storage, prices still are slightly higher than the industry average — $152/kWh this year, a 16% fall from last year’s average, and only $20/kWh higher than the average. As the scale of other sectors grows, we expect prices to continue trending closer to our industry average.
2021 has been a wake-up call for the battery industry, with the realization that we are at a point now where prices may not necessarily fall every year. In the long run, I’m still confident prices in 2030 will be close to half of what they are today, but it may not be smooth sailing to get there. For the moment we need to concentrate on getting the industry through the next 18 months, to ensure the continued electrification of transport and other sectors.

Flying taxis will face a key test come 2024, when the summer Olympic games will be held in Paris. To ensure smooth ferrying of athletes and guests to and from airports and a few Olympic venues, France plans to operate two dedicated flight paths. Several companies, including Volocopter, Airbus, Vertical Aerospace Group, Lilium and Joby Aviation will participate in the project along with France’s civil aviation authority. Testing is expected to start in the coming months. The project adds to a growing list of planned bases around the world, including those being promoted by infrastructure firm Urban-Air Port and South Korean automaker Hyundai Motor, which is targeting the opening early next year of a first site in Coventry, England.
