新發現有望讓鋰礦開採更具永續性
New Discovery Could Make Lithium Mining More Sustainable
隨著電動車電池需求成長，全球對於鋰礦的探尋已來到轉捩點。
As the demand for electric vehicle batteries grows, the global search for lithium has hit a turning point.
傳統上，鋰礦開採依賴大規模且耗費資源的蒸發池，需消耗大量水資源與土地。
Traditionally, lithium mining relied on large, resource-heavy evaporation ponds that consumed vast amounts of water and land.
如今，產業正從「開採」思維轉向更智慧的「回收」策略。
Today, the industry is shifting from an 'extractive' mindset toward a smarter 'recovery' approach.
其中一項極具前景的進展是直接鋰萃取（Direct Lithium Extraction，簡稱DLE）。
One of the most promising advancements is Direct Lithium Extraction (DLE).
透過使用先進薄膜與離子交換樹脂，DLE能將鋰從滷水中取出，過程只需數天而非數年，同時能降低高達50%的耗水量。
By using advanced membranes and ion-exchange resins, DLE can pull lithium from brines in days rather than years, while cutting water usage by up to 50%.
此外，研究人員發現，在古老的頁岩中也能找到鋰，這提供了一種能重新利用工業廢棄物，而非開發新礦場的方式。
Furthermore, researchers have discovered that lithium can even be found in ancient shale rock, offering a way to repurpose industrial waste rather than opening new mines.
其他如利用現有石油基礎設施來獲取地下滷水的創新，亦協助企業縮短供應鏈並減少碳足跡。
Other innovations, such as using existing oil infrastructure to access underground brines, are helping companies shorten supply chains and reduce their environmental footprint.
雖然這些技術需消耗大量能源，但若以太陽能或風能等再生能源供電，將能使鋰供應鏈真正實現永續發展。
While these technologies require significant energy, powering them with renewable sources like solar or wind could make the lithium supply chain truly sustainable.
