General Motors is expanding its energy business with a new focus on sodium-ion battery technology designed for grid-scale energy storage systems.
通用汽車正藉由專注於為電網級儲能系統設計的鈉離子電池技術，來擴張其能源業務。
Prototype production is set to begin at GM’s facility in Michigan by 2026.
原型生產預計於 2026 年在通用汽車位於密西根州的工廠開始。
Importantly, GM clarifies that these batteries will not be used in electric vehicles, as their energy density is insufficient for automotive needs.
值得注意的是，通用汽車澄清這些電池將不會用於電動車，因為其能量密度不足以滿足汽車需求。
Instead, sodium-ion technology is ideal for the power grid because it uses abundant, cost-effective materials and performs well across various temperatures without requiring complex cooling systems.
相反地，鈉離子技術非常適合電力電網，因為它使用豐富且具成本效益的材料，並且在各種溫度下都能表現良好，同時不需要複雜的冷卻系統。
This initiative represents the fourth battery chemistry in GM’s portfolio, joining NMC, LFP, and LMR technologies.
這項計畫代表通用汽車投資組合中的第四種電池化學技術，加入了 NMC、LFP 和 LMR 技術的行列。
By diversifying its approach, GM is positioning itself as a distributed utility, aiming to meet the surging energy demands of AI data centers and renewable energy integration.
透過分散其策略，通用汽車將自身定位為分散式公用事業，旨在滿足人工智慧數據中心與再生能源整合所帶來的激增能源需求。
Ultimately, GM is segmenting its technologies to use the right chemistry for the right application, ensuring efficiency in both transportation and stationary energy storage.
最終，通用汽車正在將其技術進行區隔，針對不同的應用選擇最合適的化學技術，以確保在交通運輸與固定式能源儲存方面皆能達到最高效率。
