With the rising demands for energy storage in recent years, finding materials for battery production that are durable and environmentally friendly has been receiving wider attention among scientists than ever before. Among renewable energy sources, black liquor from rice husk pretreatment processes has been shown to possess huge potential for anodic electrodes in lithium-ion batteries due to their high silica content. In a similar manner, black liquor from rice straw material, which has not been widely investigated, can also be a prospective candidate with its high concentration of silica. This study, therefore, retrieved lignin-silica hybrids from black liquor originating from the rice straw pretreatment stage for lithium battery anode production. The carbonized lignin–silica material experienced an enhanced initial specific charge capacity of 1668 mAh g −1 and a stable cycling capacity at 100 cycles. Based on these achievements, the study created profound progress in valorizing black liquors to solve environmental problems as well as provided a new resource to support energy storage technology.
