A Little Surprise for Our Lanran Ladies
This Women’s Day, we wanted to do something more than just greetings. So we put together a small surprise for all our female colleagues:💐Fresh flowers to brighten the day，🍰 Sweet treats because why not，💰 And a little cash gift—because appreciation feels even better when it’s real. Simple gestures, but our way of saying: we see you, we value you, and we’re grateful to have you on the team. Happy Women’s Day to all the amazing women out there!💛
From Tibet to Qinghai: Why China’s Top Salt Lake Lithium Projects Choose the Same Core Technology?
Ever wonder what powers the lithium behind the energy transition? Look to China’s salt lakes. 🏔️ And there, you’ll find a consistent pattern: the leading projects, from mega-expansions to high-altitude pioneers, integrate electrodialysis (ED) and bipolar membrane electrodialysis (BMED). At Lanran, we’re proud to be the technology partner behind this trend. Our map tells the story: Our ED/BMED systems are on the ground across major lithium regions. Success here isn’t about one-off sales; it’s about repeat partnerships. When a client’s Phase 1 works, they come back for Phase 2 and Phase 3. Here’s what we repeatedly deliver:✅ Scalable Concentration & Purification: Reliable, high-capacity ED for lithium enrichment and critical boron removal.✅ The On-Site Chemical Plant: Game-changing BMED technology that generates acid and alkali on-site from salts. This solves huge logistical headaches in remote areas and enables direct production of battery-grade lithium hydroxide.✅ The Process Integration Expertise: We don’t just ship stacks. We co-design solutions that fit seamlessly into “adsorption + membrane” flow sheets, de-risking project execution. Two quick examples: For a Qinghai Mega-Project: Our ED system became the core of their multi-phase, 10k+t/y expansion for its unwavering reliability. For a Tibetan Pioneer: Our ED+BMED combo enabled a groundbreaking process at 4,500m+, eliminating acid transport and fast-tracking battery-grade LiOH production. The lesson is clear: for efficient, sustainable, and operationally smart salt lake lithium extraction, advanced membrane technology is non-negotiable. We are Lanran. We make the core membrane systems that make lithium extraction work. 👉 Explore the full LANRAN Salt Lake Lithium project map to see all our references: https://www.google.com/maps/d/edit?mid=1dYANYXUo38jvvjJpdj81n2wktdSPtpM&usp=sharing
Reflecting on 2025 & Charging Ahead into the New Year
Last week, the Jiangshan Lanran team gathered in Wuyi for our annual year-end meeting—a time to reflect, realign, and recharge. Throughout the afternoon, our R&D, facility construction, production, sales, and HR teams shared key achievements, lessons learned, and goals for the year ahead. It was inspiring to hear from our colleagues and see how each department’s efforts contributed to our growth. A special thanks to our Chief Scientist, Dr. Yinlin Lei, for his insightful feedback, and to Chairman Yongtong Lou for his encouraging words and clear vision. He highlighted both our progress and the challenges ahead, setting a “steady progress, quality improvement, and innovative breakthrough” tone for 2026. Most of all, thank you to every member of the Lanran team. Your hard work and dedication are what drive us forward. As we step into the new year, we are energized and ready to collaborate even more closely with our customers and partners. We look forward to supporting your goals with continued innovation, reliable supply, and stronger teamwork—building progress together.
