Palladium’s second act: Nornickel bets on lithium-sulphur battery research

Summary

• Nornickel is investing in palladium-based research aimed at improving the performance of lithium-sulphur (Li-S) batteries.
• The initiative reflects efforts to diversify palladium demand as usage in internal combustion engine (ICE) catalytic converters declines.
• While Li-S batteries promise higher energy density, commercial deployment timelines remain uncertain, with industry-wide challenges still unresolved.

MOSCOW, April 14, 2026 — Nornickel is stepping up efforts to reposition palladium for the electric vehicle era, backing research into lithium-sulphur (Li-S) batteries as part of a broader strategy to offset weakening demand from traditional automotive uses.

Addressing lithium-sulphur limitations

Lithium-sulphur batteries have long been studied for their potential to deliver significantly higher energy density than conventional lithium-ion systems. However, commercialization has been limited by technical barriers—most notably the “polysulfide shuttle effect,” which leads to rapid degradation and short cycle life.

Nornickel is exploring the use of palladium-based materials as catalysts to stabilize battery chemistry. Early-stage research suggests such materials may help:

• Improve cycle stability
• Reduce degradation rates
• Enhance overall battery lifespan

However, these solutions are still in development and validation phases, with no confirmed large-scale commercial deployment yet.

Strategic shift beyond autocatalysts

Palladium demand has historically been dominated by catalytic converters in petrol vehicles, which account for a major share of global consumption. As electric vehicle adoption rises, this demand is expected to decline structurally.

By investing in battery-related applications, Nornickel aims to:

• Develop new industrial use cases for palladium
• Reduce dependence on ICE-linked demand cycles
• Support long-term price stability for the metal

The company is also exploring additional applications in hydrogen technologies and advanced materials, particularly in Asian markets.

Commercial reality check

While Li-S batteries are often cited as a next-generation alternative, industry experts caution that:

• Cycle life and durability remain key challenges
• Scaling manufacturing is still complex
• Competing technologies (like advanced lithium-ion and solid-state batteries) are progressing rapidly

As a result, mass-market EV adoption of Li-S technology is unlikely in the near term, though pilot projects and prototypes may emerge later in the decade.

Why this matters

• Battery innovation race: Li-S remains a high-potential but high-risk technology in next-gen energy storage.
• Palladium demand shift: Mining companies are actively seeking new demand drivers beyond ICE vehicles.
• EV evolution: Breakthroughs in battery chemistry could significantly impact vehicle range and cost structures.

FAQs

Q1. Are lithium-sulphur batteries ready for EVs today?

No. They are still largely in the research and prototype stage, with commercialization challenges yet to be solved.

Q2. Why is palladium being used in battery research?

Palladium has catalytic properties that may help stabilize chemical reactions inside advanced batteries.

Q3. Could Li-S batteries replace lithium-ion?

Potentially in the long term, but lithium-ion technology continues to dominate due to its proven reliability and scalability.
