據全球能源新聞網6月11日報道，日前斯倫貝謝新能源（Schlumberger New Energy）與松下北美公司旗下北美松下能源宣布，雙方已達成一項合作協議，為斯倫貝謝新能源公司位于內華達州的NeoLith Energy試點工廠驗證和優化創新和可持續的鋰提取和生產工藝。此次合作為改進鋰生產解決方案鋪平了道路，將有助于滿足全球電動汽車(EV)市場預期的鋰需求激增。
NeoLith Energy的可持續方法使用差異化的直接鋰提取(DLE)工藝來生產高純度的電池級鋰材料，同時將生產時間從一年多縮短到幾周。這一獨特的工藝與傳統的蒸發式鋰提取方法形成了鮮明的對比，顯著減少了地下水和物理足跡。松下將提供他們的指導，以驗證和優化用于電池級消耗的鋰材料。該試驗工廠位于內華達州克萊頓谷，距離松下位于內華達州斯帕克斯的大型先進電池制造工廠——北美松下能源公司僅200英里。
作為一家全球技術公司和鋰離子電池的領導者，松下在為汽車行業提供動力的創新和先進產品及解決方案方面有著久經考驗的業績。未來十年，電池級鋰的需求預計將呈指數級增長。由于電動汽車極大地依賴于鋰離子充電電池，可持續和高效的鋰生產已經成為地區、行業和科技公司，以及電池和大型汽車制造商的重要課題。盡管鋰行業預計將吸引大量投資，但新開發項目和地區的首次鋰生產時間將對該行業滿足激增的需求至關重要。
NeoLith Energy的目標是從地下抽取鹽水，提取90%以上的溶解鋰，并以環境安全的方式將85%以上的鹽水泵回地下。除了最大限度地回注鹽水外，最終目標是消除對任何來自外部來源的淡水的需求并減少對環境的影響。
松下和斯倫貝謝新能源公司致力于加快創新鋰生產工藝的開發和實施，致力于經濟、環保和負責任的開采，以促進世界向新能源的過渡。
總部位于日本大阪的松下公司，是一家為消費電子、住房、汽車和B2B領域廣泛應用開發創新技術和解決方案的全球領導者。該公司于2018年慶祝了其成立100周年。

SCHLUMBERGER AND PANASonIC TO WORK ON NEW LITHIUM BATTERY PRODUCTION PROCESS
Schlumberger New Energy and Panasonic Energy of North America, a division of Panasonic Corporation of North America, announced that they have entered into a collaboration agreement for the validation and optimization of the innovative and sustainable lithium extraction and production process to be used by Schlumberger New Energy at its NeoLith Energy pilot plant in Nevada. This collaboration paves the way for improved lithium production solutions that will help meet the expected surge in demand for lithium as the electric vehicle (EV) market takes off worldwide.
NeoLith Energy’s sustainable approach uses a differentiated direct lithium extraction (DLE) process to produce high-purity, battery-grade lithium material while reducing the production time from over a year to weeks. The unique process is in sharp contrast to conventional evaporative methods of extracting lithium, with a significantly reduced groundwater and physical footprint. Panasonic will provide their guidance to validate and optimize the lithium material for battery-grade consumption. Situated in Clayton Valley, Nevada, the pilot plant is just 200 miles from Panasonic’s large-scale advanced battery manufacturing operation, Panasonic Energy of North America, in Sparks, Nevada.
As a global technology company and leader in lithium-ion batteries, Panasonic has a proven track record in innovation and advanced products and solutions that power the automotive industry. Demand for battery-grade lithium is projected to grow exponentially over the next decade. As EVs greatly depend on lithium-ion rechargeable batteries, sustainable and efficient lithium production has become an important topic for regions, industries and technology companies, as well as battery and large automotive manufacturers. While the lithium industry is expected to attract large investments, the time-to-first-lithium-production for new development projects and regions will be critical for the industry to meet the surge in demand.
NeoLith Energy’s objective will be to pump brine from the subsurface, extract greater than 90% of the dissolved lithium, and pump more than 85% of the brine back to the subsurface in an environmentally safe manner. In addition to maximizing the reinjection of the brine, the ultimate goal is to eliminate the need for any fresh water from an external source and reduce the environmental impact.
Together, Panasonic and Schlumberger New Energy aim to accelerate the development and implementation of an innovative lithium production process, with a commitment to economical, environmental and responsible extraction to empower the world’s transition to new energy sources.
Panasonic Corporation headquartered in Osaka, Japan, is a global leader developing innovative technologies and solutions for wide-ranging applications in the consumer electronics, housing, automotive, and B2B sectors. The company, which celebrated its 100th anniversary in 2018.
