BNEF: Li-ion battery pack prices rise for first time since 2010 to an average of $151/kWh

Rising raw material and battery component prices and soaring inflation have led to the first increase in lithium-ion battery pack prices since BloombergNEF (BNEF) began tracking the market in 2010. 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 2022, a 7% rise from last year in real terms.

he 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 2022. 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 2022 had it not been for the higher adoption of the low-cost LFP cathode chemistry 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 2022. However, even low-cost chemistries such as 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 2022, compared to 2021.

Raw material and component price increases have been the biggest contributors to the higher cell prices observed in 2022. 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 such as lithium, nickel and cobalt have moderated slightly in recent months, BNEF expects average battery pack prices to remain elevated in 2023 at $152/kWh (in real 2022 dollars).

BNEF expects battery price to start dropping again in 2024, when lithium prices are expected to ease as more extraction and refining capacity comes online. Based on the updated observed learning rate, BNEF’s 2022 Battery Price Survey predicts that average pack prices should fall below $100/kWh by 2026. 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.

Despite a setback on price declines, battery demand is still reaching new records each year. Demand will reach 603GWh in 2022, which is almost double that in 2021. 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.

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.
