For practical application, advanced lithium-ion battery systems are vital to meeting the continuous energy demands and leveling the intermittent and cyclic nature of these energy sources. Creation of nanostructured electrode materials represents one of the most attractive strategies to dramatically enhance battery performance, including capacity, rate capability, cycling life, and safety. Here, we present nanostructuring of silicon-based anode materials for lithium-ion batteries. The Si-based electrodes having porous structures accommodate large volume changes during lithium insertion and extraction. These materials showed a highly stable cycling performance. The synthetic route described herein is simple, low-cost, and mass producible (high yield of ＞40% in over tens of gram scale per batch), and thus, provides an effective method for producing high-performance anode materials. |
