Recent progress on phosphate-based electroactive materials for supercapacitor applications

Abstract

Currently, the global energy consumption is extensively increasing at a pace faster than the source advancement. The demand for renewable energy generation is an important scheme to settle energy crisis and climate changes which are prominent challenges facing the modern society. Therefore, fabrication of efficient energy storage and conversion technologies have been emerged as a prospective research topic to achieve a convenient utilization of clean energy. In particular, supercapacitors are among the most effective and practically feasible energy storage devices. They offer several characteristic attributes, including fast charging rates, high power densities, extended durability, and convenient setup. Supercapacitor plays an important role as a clean energy device to link conventional capacitors with batteries. This review concentrates on the most recent progress on phosphate-based electroactive materials for supercapacitor application. Phosphate based materials have received curious attention as electrode material for supercapacitors due to their abundance, non-toxicity, and other admirable electrochemical properties. This review presents the recent progress on practical application of phosphate based materials in supercapacitors. The key performance metrics such as power and energy density, capacitance, and cyclic stability of several phosphate based supercapacitor devices have been summarized. Finally, the review present conclusive and future perspectives on the study area.
