The Department of Energy&#;s (DOE&#;s) Vehicle Technologies Office estimates the cost of an electric vehicle lithium-ion battery pack declined 89% between and (using constant dollars). The estimate is $153/kWh on a usable-energy basis for production at scale of at least 100,000 units per year. That compares to $1,355/kWh in . The decline in cost is due to improvements in battery technologies and chemistries, and an increase in manufacturing volume. 

BloombergNEF&#;s annual battery price survey finds prices increased by 7% from to

New York, December 6, &#; Rising raw material and battery component prices and soaring inflation have led to the first ever increase in lithium-ion battery pack prices since BloombergNEF (BNEF) began tracking the market in . After more than a decade of declines, volume-weighted average prices for lithium-ion battery packs across all sectors have increased to $151/kWh in , a 7% rise from last year in real terms. The upward cost pressure on batteries outpaced the higher adoption of lower cost chemistries like lithium iron phosphate (LFP). BloombergNEF expects prices to stay at similar levels next year, further defying historical trends.

The above figures represent an average across multiple battery end-uses, including different types of electric vehicles, buses and stationary storage projects. For battery electric vehicle (BEV) packs in particular, prices were $138/kWh on a volume-weighted average basis in . At the cell level, average BEV prices were just $115/kWh. This indicates that on average, cells account for 83% of the total pack price. Over the last three years, the cell-to-pack cost ratio has diverged from the traditional 70:30 split. This is partially due to changes to pack design, such as the introduction of cell-to-pack approaches, which have helped reduce costs.

On a regional basis, battery pack prices were cheapest in China, at $127/kWh. Packs in the US and Europe were 24% and 33% higher, respectively. Higher prices reflect the relative immaturity of these markets, the higher production costs, the diverse range of applications and battery imports. For the higher end of the range, low volume and bespoke orders push prices up.

Prices could have risen further in had it not been for the higher adoption of the low-cost cathode chemistry known as LFP, and the continued reduction of expensive cobalt in nickel-base cathodes. On average, LFP cells were 20% cheaper than lithium nickel manganese cobalt oxide (NMC) cells in . However, even low-cost chemistries like LFP, which is particularly exposed to lithium carbonate prices, have felt the bite of rising costs throughout the supply chain. LFP battery pack prices rose 27% in , compared to .

Evelina Stoikou, an energy storage associate at BNEF and lead author of the report, said: &#;Raw material and component price increases have been the biggest contributors to the higher cell prices observed in . Amidst these price increases for battery metals, large battery manufacturers and automakers have turned to more aggressive strategies to hedge against volatility, including direct investments in mining and refining projects.&#;

While prices for key battery metals like lithium, nickel and cobalt have moderated slightly in recent months, BNEF expects average battery pack prices to remain elevated in at $152/kWh (in real dollars).

BNEF expects battery price to start dropping again in , when lithium prices are expected to ease as more extraction and refining capacity comes online. Based on the updated observed learning rate, BNEF&#;s Battery Price Survey predicts that average pack prices should fall below $100/kWh by . This is two years later than previously expected and will negatively impact the ability for automakers to produce and sell mass-market EVs in areas without subsidies or other forms of support. Higher battery prices could also hurt the economics of energy storage projects.

Yayoi Sekine, head of energy storage at BNEF, said: &#;Despite a setback on price declines, battery demand is still reaching new records each year. Demand will reach 603GWh in , which is almost double that in . Scaling up supply at that rate of growth is a real challenge for the industry, but investment in the sector is also rising rapidly and technology innovation is not slowing down.&#;

Kwasi Ampofo, head of metals and mining at BloombergNEF, added: &#;Lithium prices remain high due to persistent supply chain constraints and the slow ramp up in new production capacity. Additional lithium supply could ease the pressure on prices in , while geo-politics and trade tension remain the biggest uncertainties for other key battery metal prices in the short-term. Resolving these tensions could help calm prices in and beyond.&#;

Continued investment in R&D, manufacturing process improvements, and capacity expansion across the supply chain will help to improve battery technology and reduce costs over the next decade. BloombergNEF expects next-generation technologies, such as silicon and lithium metal anodes, solid-state electrolytes and new cathode material and cell manufacturing processes, to play an important role in enabling further price reductions.
