SiOx Nanodandelion by Laser Ablation for Anode of Lithium‐Ion Battery

Silicon-based nanoparticles with unique "nanodandelion" structures are synthesized by a simple and efficient laser ablation method. Such material can be used as a stable anode for Li-ion batteries with a high capacity of ≈1500 mAh g(-1) and for more than 800 electrochemical cycles without obvious capacity decay.
