Battery value shifts downstream as lithium supply grows and manufacturing know-how goes on sale

96% of battery value sits after the mine, this week the race moved downstream – Lithium supply grows, but the real money is in making the battery

⚡ The 60-Second Brief

1. Lithium supply keeps growing. Rio Tinto opened $1.4 billion of lithium projects in Argentina, adding 25,000 tonnes of annual capacity, and LibertyStream signed to supply up to 17,500 tonnes of US-made lithium carbonate to a cathode maker.
2. But the value is downstream. Australia’s CSIRO says 96% of battery revenue sits after mining, and points to two practical first steps: aluminium cell cans and copper foil.
3. Manufacturing know-how is now for sale. LG’s production engineering arm, which has built 260+ battery lines including 76 in the US, is offering turnkey lines to North American manufacturers.

The lead: everyone has lithium, few can make batteries

This week’s stories add up to one message: the battery race is shifting from digging to making.

More lithium is coming:

• Rio Tinto opened its Fénix 1B expansion and new Sal de Vida operation in Catamarca, Argentina, with President Milei in attendance. Combined investment: about $1.4 billion. Capacity: 25,000 tonnes LCE a year once ramped. Both reached first production ahead of plan. Rio targets 200,000 tonnes LCE by 2028.
• LibertyStream will supply 500 tonnes of US-origin lithium carbonate in 2027 to an unnamed cathode maker serving the US, with binding terms for 17,000 more tonnes through 2031. It extracts lithium from Texas oilfield brine. But it still needs to build and finance the capacity to deliver.

But that’s not where the money is:

• CSIRO says 96% of the battery revenue opportunity sits downstream of mining, yet Australia exports most of its minerals. Its two practical first steps: prismatic cell cans made from Australian aluminium, and electrodeposited copper foil (about 6 microns thick) using local copper refining skills.
• LG Electronics’ Production Engineering Research Institute has supported 260+ battery lines globally, 76 in the US, and appointed Ratel Consulting to sell turnkey lines in North America, starting with module and pack.
• Ratel’s founder put it plainly: the hard part is not building a plant, it’s ramping it to hit yield, quality and throughput.

→ Why it matters: Lithium is getting easier to secure. Ramping a factory isn’t. The winners in the next phase will be the countries and companies that can turn raw materials into reliable components and running lines. That’s why LG is now selling its experience, and why Australia is starting with cans and foil, not full cells.

🔢 Number of the Week: 96%

Share of the battery revenue opportunity that sits downstream of mining, according to Australia’s National Battery Strategy cited by CSIRO. Countries that only mine and export capture the smallest slice.

🚗 EV & MOBILITY

Mercedes-Benz shows a battery Power Converter.

• Programmable micro-converters control energy flow from individual cells, delivering a steady output of up to 800V regardless of each cell’s charge or age. The current version handles up to 3 kW and supports AC/DC and bidirectional charging.
• High voltage no longer depends on how many cells are wired in series; software sets it instead.

→ Why it matters: If voltage is set by software, pack design gets more flexible and a few weak cells no longer limit the whole pack. Still research, not production.

Ampace targets two-wheelers at EICMA.

• Its battery-swapping network in Africa has completed 17 million swaps over 2.5 years, with each pack averaging over 1,000 cycles.
• New off-road cells use high-nickel cathodes and silicon-carbon anodes; its tabless design cuts internal resistance by 80%.

🔋 STORAGE & SECOND LIFE

EDENenergy turns used e-scooter batteries into industrial storage.

• The Fraunhofer ISE spin-off delivered its first 70 kWh system in October, built from 112 second-life e-scooter batteries.
• Germany discards about one million e-bike and e-scooter batteries a year. Of the first 350 tested, many still had well over 90% capacity, beating the 80% expected.
• Modules can be swapped while running, so the system holds 70 kWh even after 10 years. Next step: 300 kWh systems.

→ Why it matters: Micromobility batteries are an untapped second-life source, but each brand uses different connectors and software. Standard protocols and second-life rules will decide whether this scales.

🧪 MATERIALS & SOLID STATE

ISU Specialty Chemical and Ares Materials team up on solid-state polymers.

• ISU, which completed a commercial lithium sulfide plant this year, will produce; Ares will use AI trained on real cell test data to tune formulations.
• The goal: when cell specs change, a new formulation becomes an adjustment rather than a restart.

Stryten Energy brings Trojan batteries to AAPEX.

• After acquiring C&D Technologies and Trojan Battery Company, Stryten now offers advanced lead, marine/RV and lithium golf cart batteries under one US-based roof.

🔍 Contrarian Corner

More lithium is coming online just as everyone chases downstream value. That’s good for cell makers, but it raises a question for miners.

Rio Tinto is targeting 200,000 tonnes by 2028, and new players like LibertyStream are signing long-term offtakes. If supply keeps outpacing demand, lithium prices stay low and the margin moves even further down the chain. The CSIRO report is right: the money is in making things. The mines may end up subsidising the factories.

---

👀 What to Watch

• LibertyStream’s long-term agreement: whether 2028–2031 volumes get finalised and financed.
• CSIRO online panel: November 24, on Australian battery manufacturing.
• Rio Tinto ramp-up: progress at Fénix and Sal de Vida toward 25,000 tonnes.
• Second-life rules: EU and German moves on standards for reusing mobile batteries.
