Solid-state EV batteries hit another major milestone in China

Chinese lithium metal giant Ganfeng Lithium has begun producing what it calls the world’s first 10 Ah solid-state batteries with an energy density of 500 Wh/kg. The lithium giant has supply deals with Tesla, Volkswagen, Hyundai, and several other major OEMs for key EV battery materials. more…

Why this matters
Why now

Advances in battery technology, particularly in solid-state chemistry and manufacturing, are reaching commercial viability due to significant R&D investment and geopolitical competition.

Why it’s important

Achieving higher energy density in EV batteries is crucial for extending range, reducing weight, and accelerating the mass adoption of electric vehicles, directly impacting energy markets and automotive industries.

What changes

The world's first 10 Ah solid-state batteries with 500 Wh/kg energy density are now being produced, potentially setting a new benchmark for EV battery performance and commercial readiness.

Winners
  • · Ganfeng Lithium
  • · Electric Vehicle Manufacturers
  • · China's EV ecosystem
  • · Consumers (EVs)
Losers
  • · Traditional ICE vehicle industry
  • · Oil & Gas industry (long-term)
  • · Less advanced battery competitors
Second-order effects
Direct

Mass production of high-density solid-state batteries begins, influencing EV range and price points.

Second

Accelerated EV market penetration leads to increased demand for charging infrastructure and grid modernization.

Third
