Rechargeable High-Energy-Density EV Battery
The rapid advancement of electric vehicles and portable electronics has driven a growing demand for efficient rechargeable batteries. However, current technologies still fall short of meeting real-world energy requirements. Developing energy storage systems with high energy density and superior performance has therefore become a critical focus. While lithium-ion batteries remain the dominant technology, their energy density is fundamentally limited by electrode materials. To overcome this, we are actively exploring advanced materials such as silicon, silicon oxide, high-performance lithium titanate, and lithium metal anodes, along with lithium-sulfur, sodium-ion, and potassium-ion batteries, as well as novel cell architectures. These innovations are expected to play a vital role in next-generation battery development.
隨著電動車技術與可攜式電子產品的迅速發展，對高效能可充式電池的需求持續攀升。然而，現有電池技術尚難以完全滿足實際應用需求，因此，發展具備高能量密度與優異性能的儲能系統成為當前關鍵課題。鋰離子電池雖為目前最成熟且廣泛應用的技術，但其能量密度仍受限於電極材料的瓶頸。為突破此限制，我們積極投入開發新型材料，如矽、矽氧化物、高性能鋰鈦氧、鋰金屬等負極材料，以及鋰硫電池、鈉/鉀離子電池與創新電池架構，這些技術有望大幅提升未來電池的整體效能與儲能密度。
Redox Flow Cells
Redox flow batteries are a class of rechargeable energy storage systems that utilize dissolved active species in liquid electrolytes. The total energy storage capacity is determined by the size of the external electrolyte tanks, making these systems highly scalable and well-suited for applications such as smart grids and stationary renewable energy storage. Flow batteries offer unique advantages, including modular design, long cycle life, and enhanced operational safety. However, several challenges remain, such as electrode degradation, crossover of active species between compartments, and the need to reduce manufacturing and system-level costs to achieve commercial viability.
液流電池是一種使用溶解態活性物質作為能量載體的可充式電池，其儲能容量主要取決於外部電解液槽的體積。因此，其可靈活調整儲能規模，特別適合應用於智慧電網與大型再生能源的定點儲能系統。相較於其他儲能技術，液流電池具有系統模組化、高安全性與長壽命等優勢。然而，目前仍面臨諸多挑戰，包括電極材料劣化、正負極物質交叉污染，以及製程規模化所帶來的成本壓力。
Alkali Metal Ion Implantation Techniques
The implantation of alkali metal ions—lithium, sodium, and potassium—has emerged as a critical technique in the development of next-generation energy storage materials. By incorporating these ions into host structures via physical or chemical methods, this approach enables compensation for initial Coulombic inefficiencies, while also tuning the structural, electronic, and ionic transport properties of the material. It is particularly relevant for anode materials such as silicon, silicon oxide, and metal oxides, and can be integrated with solid-state electrolytes or high-energy-density battery systems. Future research will focus on improving the uniformity of ion distribution, enhancing interfacial stability, and scaling the process for practical electrode manufacturing.
