Scalable synthesis of spherical Si/C granules with 3D conducting networks as ultrahigh loading anodes in lithium-ion batteries

Spherical Si/C granules are optimally designed and synthesized via a flexible and scalable fabrication process. The obtained Si/C anodes exhibit excellent electrochemical performance at ultrahigh mass loading (8.5 mg cm-2) and pressing density (1.6 g cm-3), and enable superior Li-ion pouch cells with LiNi0.5Co0.3Mn0.2O2 as cathode materials.187
