IEEE Spectrum, is the world’s largest professional organisation devoted to engineering and the applied sciences. It contains peer-reviewed feature articles pertaining to technology and science trends affecting business and society. This spectrum was conducted to enlighten the young minds and some skillful knowledge out of it. The speaker Mr. K. Aakashvel spoke on “ Could lithium extraction could be a game changer ”. The speaker enlightened us with the idea that “ Direct lithium extraction (DLE) technologies could be a “potential game-changing technology for lithium supply” . These technologies could double the production of lithium from existing brine operations and unlock new sources of lithium, reducing land and water use, and waste .Currently, lithium is extracted by pumping water up to the surface and letting it evaporate until the lithium salts become concentrated enough to filter out. This process takes over a year, leaving behind piles of waste containing other metals and draining nearly 2 million litres of local water resources, harming indigenous communities .DLE technologies take hours instead of months and involve chemically or physically filtering out lithium from brines and injecting the brine back underground. Summit Nanotech, one of about a dozen young companies piloting new DLE processes, aims to commercialise its DLE technology as early as 2025 .The demand for lithium is expected to increase over 40 times by 2040, according to the Cleantech Group . The discovery of lithium deposits can be a potential “game changer” for India’s clean energy manufacturing ambitions in several ways, according to Siddharth Goel, senior policy advisor at the International Institute for Sustainable Development (IISD) .”The participants had an amazing experience in the meet.
