Biomass-derived materials empowering solid-state batteries: progress, challenges, and prospects

Solid-state batteries (SSBs) are considered the core of the next generation of energy storage technology due to their high safety and energy density. However, the commercialization of SSBs still faces challenges such as low ionic conductivity of solid electrolytes, poor electrode/electrolyte interface stability, and high material cost. In recent years, biomass-derived materials have attracted much attention for use in the key components of SSBs such as electrolytes and electrodes due to their renewability, low cost and unique chemical structure. In this paper, the latest research progress of biomass-derived materials in SSBs is systematically reviewed, focusing on their component and structural design, performance optimization mechanism and scale application potential, and the future development direction is proposed.
