Lithium Battery Packs Hit a Record $108 a Kilowatt-Hour as Grid Storage Collapses to $70 — The Crash That Is Rewiring Cars and Power Grids

Wind and solar are cheap when the weather cooperates and worthless when it does not. Storage is the missing half of that sentence. For fifteen years the sentence ended with “too expensive.” It does not anymore.

BloombergNEF’s December 9, 2025, survey put the volume-weighted average lithium-ion pack at $108 per kilowatt-hour, down 8 percent from 2024 and a record low. In 2010 the same pack, in today’s dollars, cost about $1,474. That is a 93 percent collapse. The 2025 drop happened while cobalt jumped on Congo export quotas and lithium ticked up on Chinese supply risk — the same metal shock that, in 2022, produced the only annual price increase BNEF has ever logged. This time the industry ate it.

Cars Crossed $100. The Grid Went to $70.

Battery-electric vehicle packs averaged $99/kWh in 2025, the second straight year under the round number Detroit used to treat as fantasy. In China, packs sit around $84/kWh and price parity with gasoline cars is already a fact across most segments. North American packs run about 44 percent higher. European packs run about 56 percent higher. That spread is why a Tesla or a BYD costs what it costs depending on which ocean you are standing next to.

Stationary storage did the violent thing. Packs headed for the grid fell 45 percent in a single year, to $70/kWh — the cheapest battery segment on Earth for the first time. The floor BNEF actually recorded was $36/kWh at the cell and $50/kWh at the pack, both lithium iron phosphate going into storage projects. Across all uses, LFP packs averaged $81/kWh. Nickel-manganese-cobalt packs averaged $128. The chemistry that does not need cobalt or nickel is eating the chemistry that does.

108 Gigawatts in a Year, More Than Gas Ever Added

The International Energy Agency’s Global Energy Review 2026 called battery storage the fastest-growing power technology in the world. In 2025 the planet installed 108 gigawatts of new storage — 40 percent more than 2024, eleven times the 2021 base. Utility-scale took about 87 GW, roughly four-fifths. China alone added just over 63 GW, about 58 percent of the global total. A May 29, 2026, IEA commentary noted that 108 GW is more than the historical peak for new gas-fired plants, about 107 GW in 2002. LFP now accounts for around 90 percent of storage deployments. Five years ago it was under half.

Electric vehicles still chew through more than 70 percent of lithium-ion demand. One in four cars sold worldwide in 2025 was an EV. Grid batteries and backup for AI data centers are the fast-growing remainder. The overall market topped $150 billion. Global lithium-ion deployment ran about six times the 2020 figure.

What the Metals Did Not Do, and What Sodium Is About to Do

The 2025 story is the non-event. Metal prices rose. Battery prices fell. Long-term contracts, hedges, and the wholesale pivot to cobalt-free LFP absorbed a shock that used to print through to the sticker. Evelina Stoikou, who runs BNEF’s battery-technology desk, called it “cut-throat competition” making batteries cheaper every year — and an opening to cut EV prices and actually put storage behind wind and solar instead of talking about it.

BNEF’s near-term outlook at the survey still pointed to another dip in 2026, to just under $105/kWh, about 3 percent, even with tariffs and raw-material pressure. CATL, the world’s largest battery maker, passed China’s GB 38031-2025 certification on its Naxtra sodium-ion cell in 2025 — 80 percent charge in about 15 minutes — and on April 21, 2026, put Naxtra on a Super Technology Day stage as the first sodium-ion pack headed for GWh-scale mass production by the end of 2026. Sodium does not need lithium. That is the point.

The remaining mess is where the dirt comes from. A large share of cobalt and lithium is still processed in China. The human and environmental cost of cobalt mining did not vanish because LFP got cheaper. Recycling of copper, aluminum, and battery metals is still a rounding error. Those are real constraints. They are no longer an excuse for $1,400 packs.
