“…More details on the activated carbon derived from waste cocoa pods with their electrochemical performance are available in the literature. [37][38][39] Due to the CoMn(PO 4 )/GF promising electrochemical results, the composite material was used as a positive electrode in part with the activated carbon from waste cocoa pods (AC) as a negative electrode to couple a hybrid device. Figure 7A represents CV profiles for both electrodes adopted in assembling the device.…”

Mn and Co are known for their redox storage mechanism depending on the kinetics of their ions, which is required to boost capacity values of the material electrodes for energy storage applications. However, to the best of our knowledge, Co-Mn phosphate material-based electrochemical capacitors have been rarely investigated. In this work, CoMn(PO 4 ) 2 synergized with graphene foam (GF) was synthesized following an easy, direct and low-temperature hydrothermal method. The study investigated the synergy between Co, Mn and GFsupported composite, with a strong P-O covalent tie occurring at the surface of the material, leading to a high degree of polarization and very low relaxation time. The CoMn(PO 4 ) 2 /GF material tested as a half-cell could achieve a specific capacity of 58.15 mAh g À1 at 0.5 A g À1 . A CoMn(PO 4 ) 2 /GF//activated carbon (AC) hybrid device was made up considering CoMn(PO 4 ) 2 /GF and an AC material as positive and negative electrodes, respectively. The CoMn(PO 4 ) 2 /GF//AC hybrid device achieved a specific capacity of 45.89 mAh g À1 , specific energy of 51.53 Wh kg À1 and a corresponding specific power of 561.52 W kg À1 at 0.5 A g À1 . Furthermore, the device displayed a 95% capacity retention after 10 000 GCD cycles at 12 A g À1 and showed improved performance over its initial specific capacity after a voltage holding test for over 110 hours at 2 A g À1 .

“…Depending on the nature of the conversion methods (i.e., thermochemical or biochemical), these components can be found in varying concentrations which can affect the characteristics of the final AC products. There are several advantages in terms of producing bio-based products from agricultural residues such as availability, affordability, renewability, and environmental-friendly (Rashidi and Yusup, 2017) (Yetri et al, 2020) (Hoang et al, 2022a). Nevertheless, there are also some major drawbacks in terms of biomass-based AC.…”

“…Burning a large quantity of crop residue has detrimental effects on humans, notably on young children and pregnant women who are susceptible to cardiovascular and respiratory diseases (Pawar and Panwar, 2020). Therefore, turning leftover crop residues into biochar and other carbon materials is a potential method to reduce CO 2 emissions released into the environment while simultaneously enhancing other advantages (Yetri et al, 2020;Kumar et al, 2022). Indeed, biochar is a cost-effective product, so it could be employed as an additive to improve the AD system's performance as mentioned above.…”
