طور باحثون في كلية الهندسة بجامعة كولومبيا تقنية جديدة لاستخراج الليثيوم من المحاليل الملحية الجوفية بشكل أسرع وبضرر بيئي أقل. وتعتمد هذه الطريقة على مذيب حساس لدرجة الحرارة، مما يغني عن استخدام أحواض التبخير الكبيرة الشائعة في الإنتاج الحالي.

تعمل هذه الطريقة، التي تُعرف باسم الاستخلاص الانتقائي بالمذيبات القابلة للتبديل (S3E)، عن طريق امتصاص الليثيوم والماء من المحاليل الملحية في درجة حرارة الغرفة. وتؤدي عملية تسخين المذيب إلى إطلاق الليثيوم المنقى مع إمكانية إعادة استخدام المادة. وأظهرت الاختبارات أن معدلات استخراج الليثيوم كانت أعلى بـ 10 مرات مقارنة بالصوديوم، وأعلى بـ 12 مرة مقارنة بالبوتاسيوم.

A joint research team from Nankai University (Tianjin) and the Shanghai Institute of Space Power-Sources has developed a hydrofluorocarbon-based electrolyte for lithium-metal batteries, achieving up to 700 Wh/kg energy density at room temperature—more than double traditional electrolytes—and stable operation down to minus 70°C. Published in Nature on February 27, 2026, the breakthrough promises to double electric vehicle ranges to 1,000 km and has applications in aerospace.

U.S. discovers huge lithium reserves in Appalachia

The United States has identified substantial lithium reserves in the Appalachian region, potentially holding up to 2.3 million metric tons of lithium oxide. These deposits could supply billions of phones and lessen American dependence on China for the critical mineral. The findings were detailed in estimates reported by TechRadar.

A team of researchers examining batteries from Tesla and BYD discovered an unexpected absence of silicon in the anodes, challenging assumptions about improving energy density in electric vehicles. The study, published in Cell Reports Physical Science, compared Tesla's 4680 cylindrical cell with BYD's Blade prismatic cell, revealing key differences in design and performance. These findings offer rare insights into the inner workings of leading EV battery technologies.
