本研究以簡易的一步合成法，成功製作出多孔的磷化鍺化合物微米球且過程中無需犧牲劑亦可獲得孔徑均勻的多孔性材料。實驗中發現常見的短碳鏈有機溶劑可作為穩定劑，如：甲苯、正己烷、苯，透過實驗參數的調整，奈米粒子能夠組裝成為具有高比例介孔洞的微米球。具有高孔隙度的材料在能源儲存上（如：離子電池）有許多優異的特性，例如：能夠縮短能量載子（鋰離子和鈉離子）的擴散距離進而提升充放電速率、提供足夠的緩衝空間和奈米等級的顆粒與孔徑。在電化學的測試下，多孔的磷化鍺化合物微米球展現了傑出的電化學特性，與現有文獻之磷化物相比，是一個具有潛力的新世代離子電池陽極材料。應用於鋰離子電池上，除了優良的可逆電容量（1400 mA h g-1在0.2 C的充放電流經歷150次循環測試）之外，該材料還具有極高的首圈庫倫效率（82.63%），即便在超高速充放電之下（40 C）仍具有高於商用石墨（372 mA h g-1）的能量密度（400 mA h g-1）。在鈉離子電池中，多孔的磷化鍺化合物微米球依然具有優異的表現，除了優秀的可逆電容量（787 mA h g-1 在0.2 C的充放電流經歷了38次循環），在高電流的充放電之下（0.6 C）也展現了不錯的循環表現(經歷170次循環仍沒有顯著的電量損失)。

Germanium phosphide is a potential anode material because of its high theoretical capacity and incredible rate capability. However, the huge volume change directly led to poor cyclability and limited the further application. Herein, mesoporous germanium phosphide (MGePx) microspheres with narrow distribution of pore sizes, 4 nm, were first prepared and well solved with the volume change problems by a one-step and template-free approach. Employing short carbon compound (toluene, hexane, benzene) as stabilizing agents in the synthesis, the nanoparticles (~10 nm) could well assemble to microspheres with diameters size ranging 0.5-1.5 μm under the proper amount of stabilizing agents added. On the other hand, without introducing stabilizing agents, the final product yielded to tense microspheres. The uncontrollable aggregations were formed when the excess stabilizing agents were existed in the reaction. The MGePx possessed superior features in LIBs/NIBs, including (Ⅰ) shortening the diffusion path of energy carrier, (Ⅱ) providing the buffer space, and (Ⅲ) nanoparticle size. MGePx showed attractive electrochemical properties to be a potential anode candidate such as high first cycle coulombic efficiency of 82.63%, high reversible capacity (1400 mA h g-1 after 150 cycles at 0.2 C), excellent ultra-high rate capacity (370 mA h g-1 at 72 A g-1, 40 C), and stable cycling performance (450 cycles at 1 C) in the LIBs and high reversible capacity (704 mA h g-1 after 100 cycles at 0.2 C ) and stable cycling performance (200 cycles at 0.6 C) in SIBs.
