A critical review on biochar-based engineered hierarchical porous carbon for capacitive charge storage

Dinh Viet Cuong et al.

Summary: Hierarchical porous carbon (HPC) has been traditionally fabricated by activated carbon, but biochar is now being explored as a renewable and more environmentally friendly alternative. Recent studies have shown that biochar-based HPC exhibits great potential in capacitive energy storage due to its unique properties. Research efforts have focused on developing biochar-based engineered hierarchical porous carbons (EHPCs) to enhance capacitive charge storage performance through techniques such as templating and doping. The review provides an overview of the applications of biochar-based HPC and EHPC in capacitive charge storage, such as capacitive deionization (CDI) and supercapacitors (SC), and offers future research directions in this field.
