CATL signs 60 GWh sodium-ion supply deal

Audio briefing

4 min

In this report
October brought larger sodium-ion orders, a promising but early solid-state cathode result, and policy signals that widen the distance between deployment targets and production readiness. Supply-chain resilience remains constrained less by mineral access than by refining capacity.
  1. CATL signed a 60 GWh sodium-ion supply deal with Beijing HyperStrong, although the largest operating plant cited is only 50 MW / 100 MWh:
  2. A coat-sinter-wash treatment gave an LRMO cathode 80% retention after 500 cycles and 543 Wh/kg in an all-solid-state pouch cell:
  3. China's battery plan targets large-scale all-solid-state use by 2030, while CATL's chairman rates readiness at 4/9 and doubts million-vehicle adoption before then:
Sodium-ion commercialization

CATL signs 60 GWh sodium-ion supply deal

General
CATL signed a three-year agreement to supply Beijing HyperStrong with 60 GWh of sodium-ion cells, while Peak Energy has secured agreements for up to 4.75 GWh. The contracts move the chemistry into commercial planning, but operating deployment and cost competitiveness remain unproven at this scale.
  • The largest operating plant cited is 50 MW / 100 MWh, despite 370 GWh of announced global manufacturing capacity and just 9 GWh shipped in 2025.
  • Sodium-ion cells still cost about twice as much as LFP; hard-carbon anode prices fell from 60,000–70,000 yuan per tonne in 2024 to 35,000–40,000 yuan in 2026.
The agreements test whether sodium-ion can progress from announced capacity into repeatable grid-storage deliveries alongside LFP.
Solid-state materials and scale-up

Study stabilizes oxygen redox in LRMO cathodes

General
A Science Advances study used a coat-sinter-wash treatment to stabilize oxygen redox in a Li-rich Mn-based layered oxide, reaching 80% capacity retention after 500 cycles at 0.5 C. An all-solid-state pouch cell with a silicon anode reached 543 Wh/kg, making this a useful materials result rather than evidence of production readiness.
  • The cathode delivered 278.2 mAh g−1 reversible capacity at 0.1 C, while the treatment suppressed surface oxygen release and improved lattice-oxygen reversibility.
  • The pouch cell reached 4.55 mAh cm−2 areal capacity; the report does not establish replication, long-duration cycling, or manufacturing yield.
The study tests whether a known failure mode in Li-rich cathodes can be managed under all-solid-state cell conditions.
Solid-state materials and scale-up

China sets 2030 target for solid-state batteries

General
China's 2026–2030 battery plan targets large-scale all-solid-state deployment by 2030, while CATL's chairman rates readiness at 4/9 and doubts million-vehicle adoption before then. The policy target is now paired with a concrete European manufacturing milestone, but industry readiness remains contested.
  • ProLogium's Dunkirk plant is set to produce 0.8 GWh by 2028 and has been certified against Chinese standards.
  • The plan also targets lithium cells capable of 15,000 charge cycles, indicating that its scope extends beyond solid-state cells to broader performance goals.
The plan sets a national deployment horizon that ProLogium's 0.8 GWh project can begin to test against in production.
Sodium-ion commercialization

Argonne sets sodium-ion cost targets

General
Argonne's inaugural Sodium Battery Summit brought together more than 70 organizations and put federal cost targets of $75/kWh by 2030 and $60/kWh by 2035 into the public discussion. The event maps a U.S. development agenda, not a demonstration that sodium-ion has reached those costs.
  • The summit covered applications including cold-start vehicle batteries and directed-energy systems, with sodium's material abundance and compatibility with lithium-ion manufacturing as central arguments.
  • The LENS Consortium is coordinating work to close the gap with LFP, while announced global manufacturing capacity of 370 GWh produced only 9 GWh of shipments in 2025.
The summit connects U.S. research coordination and procurement ambitions to the same scale-up problem exposed by current sodium-ion orders.
Supply-chain resilience

Allies plan selective de-risking for battery supply chains

General
A supply-chain report projects China retaining 60–80% of refined lithium, cobalt, and graphite capacity by 2035, even if Western countries secure mineral resources. Its proposed response is selective de-risking through cooperation among the U.S., Canada, and Australia rather than an attempt to duplicate the entire chain.
  • The constraint identified is processing and refining capacity, not simply access to ore; China remains structurally ahead at that intermediate stage.
  • The proposed division of strengths assigns finance, mining, and processing roles across the coalition, making coordination an industrial requirement rather than a trade slogan.
The report shifts resilience analysis from resource ownership to the refining capacity that determines whether materials can enter cell production.
