Favorable anion adsorption/desorption of high rate NiSe2 nanosheets/hollow mesoporous carbon for battery-supercapacitor hybrid devices

Towards a broad-operation window for stable CO2electroreduction to HCOOH by a design involving upcycling electroplating sludge-derived Sn@N/P-doped carbon

“…The characteristic peaks of carbon material appeared at ∼1330 cm −1 (D band) and ∼1584 cm −1 (G band) for Sn@NPC and pristine NPC. 48,49 The intensity ratio of I D / I G for Sn@NPC was calculated to be 0.97, possibly by virtue of the local deformation of the carbon material originating from Sn introduction, which was the reason for the increased I D /I G value of Sn@NPC compared to NPC (I D /I G = 0.86). From the above results, it was verified that the Sn@NPC composites had been successfully synthesized on the bacterial template.…”

Oxygen-Defect Enhanced Anion Adsorption Energy Toward Super-Rate and Durable Cathode for Ni–Zn Batteries

“…Therefore, these empty states could store more charges, leading to a higher capacity. The intermediate adsorption behavior of OH − on the surface of the active material is very important for the reversible capacity of the electrode material [51]. With the combination of more available unoccupied states and the strong OH − adsorption capacity, the Faraday reversible redox reaction will be promoted, thereby improving the charge storage capacity [52].…”

High-rate transition metal-based cathode materials for battery-supercapacitor hybrid devices

“…Thus, it makes sense to study the catalytic effect of electrode materials, further enhancing the rate performance and cycling stability of electrode materials. 180,181 Transition metal sulfides have received great attention in the application of energy conversion and storage devices due to their high specific capacity and rate performance. Therefore, the Ni 9 S 8 /O-MoS 2 composites also owned highly electrocatalytic properties, which can be applied for hydrogen production.…”
