Printable Carbon‐Based Thermogalvanic Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The performance of printable active carbon as the electrodes of thermogalvanic cells is investigated. The maximum output power can be doubled by multilayer printing of the electrode, which reduces the internal resistance of the cell. Thermogalvanic cells (TGCs) can convert low‐grade heat directly into electricity through reversible redox reactions ...

Energy Harvesting from CO2 Emission Exploiting Ionic Liquid‐Based Electrochemical Capacitor

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The concept proposes energy harvesting from CO2 emissions using ionic liquids (IL)‐based supercapacitor. By alternating CO2 and N2 gasses during electrode charging/discharging, the energy from salinity gradients is captured. ILs absorb CO2, altering electrode/IL interactions and generating electrical energy. This method introduces for the first time an

Improving the Rate and Cycle Performances of Porous Silicon Particles Prepared by Acid Etching of Al–Si Alloy Powders for Application in Lithium‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A scalable method is presented to manufacture high‐capacity Si electrodes for Li‐ion batteries where skeletal porous Ti(Al,Si)2@Si particles are synthesized by gas atomization and acid etching. The fine pores have a buffering effect that suppresses volume expansion during lithiation, and the high electrical conductivity of the particles greatly ...
