Abstract Silicon nanostructures and their composites are believed to be very promising anode material candidates for advanced lithium‐ion batteries. Yet, anode material systems developed, to date, inevitably require complex and time‐consuming synthetic processes, or complicated and expensive instruments, or hazardous chemicals, or electrode fabrication procedures that are incompatible with current slurry‐based electrode fabrication techniques. This situation notoriously hinders the practical implementation of silicon in lithium‐ion batteries. Herein, a simple, facile, eco‐friendly chopping strategy is demonstrated for the construction of silicon nanoparticle impregnated pyrolyzed bacterial cellulose (PBC). The resulting hybrid material exhibits significantly improved lithium storage performance compared with its counterparts; this reflects great potential for the reconstruction of PBC‐based three‐dimensional conductive networks. This study provides the potential for the simple and efficient construction of electrode materials and systems in a much more viable and sustainable manner.
