πŸ”‹ Lepidolite: A Key to Securing Lithium Supply for the New Energy Era


Lithium has become the backbone of the global new energy strategy. From powering high-energy batteries to applications in nuclear power, glass ceramics, and specialty greases, its unique physical and chemical properties make it irreplaceable. By 2019, 65% of global lithium consumption was already dedicated to batteries, and that share continues to rise.

But as demand soars, securing a stable lithium supply has become a top concern for technology companies worldwide. While salt lake brines remain the dominant source, lithium-bearing minerals like lepidolite are emerging as vital supplementary resources.

In my latest article, I dive deep into:
✅ Methods of lithium extraction from lepidolite — including chloride roasting, sulfate roasting, limestone roasting, and the sulfuric acid method.
✅ Why sulfuric acid digestion has become one of the most energy-efficient and widely adopted techniques.
✅ The critical challenge of aluminum removal from lepidolite leach solutions, and why traditional chemical precipitation is costly and inefficient.
✅ How nanofiltration (NF) membranes are transforming lithium extraction, offering high Li/Al separation efficiency and paving the way for lower-cost, more sustainable recovery.

Lepidolite may not replace brine or spodumene entirely, but its role in alleviating lithium supply pressures is becoming more important than ever. And with advanced separation technologies, its potential is even greater.
