Nanjing team develops solar-powered electrolysis process for extraction of lithium from seawater

Currently all commercial lithium is sourced from ores and brines on land, which contains a total lithium reserve of 14 million tons according to the latest survey conducted this year. … the geographic distribution of land-based lithium resources is uneven, with more than 98% of the total reserves concentrated in Chile, Argentina, China, and Australia. In addition, lithium extraction from ores and brines has a significant environmental impact, including water pollution and depletion, soil damage, and air contamination. … In contrast, the ocean contains 230 billion tons of lithium, an amount four orders of magnitude larger than the lithium reserves on land. Since the amount of lithium in this massive reserve is far higher than the amount consumed annually by human activity, the impact of lithium extraction from seawater on the lithium concentration in the ocean would be negl...
