Bead‐Like Coal‐Derived Carbon Anodes for High Performance Potassium‐Ion Hybrid Capacitors

ChemElectroChem, 2022
The pursuit of long life, high rate and low‐cost anode materials is of great significance for potassium‐ion hybrid capacitors (PIHCs). Here, the bead‐like coal‐derived carbon films (BCCFs‐800) for PIHCs were synthesized with low‐cost coal as precursor ...

Electrochemical Alloying of Lead in Potassium-Ion Batteries [PDF]

ACS Omega, 2018
The electrochemical alloying of lead-based electrodes with potassium was investigated by galvanostatic measurements as well as by ex situ and operando X-ray diffraction. The electrochemical reduction must be activated by an initial high current pulse which prevents the passivation of the lead electrode.

Characterisation and Modelling of Potassium-ion Batteries

Nature Communications
Abstract Potassium-ion batteries (KIBs) are emerging as a promising alternative technology to lithium-ion batteries (LIBs) due to their significantly reduced dependency on critical minerals. KIBs may also present an opportunity for superior fast-charging compared to LIBs, with significantly faster K-ion electrolyte transport properties already ...

2023 roadmap for potassium-ion batteries

Journal of Physics: Energy, 2023
Abstract The heavy reliance of lithium-ion batteries (LIBs) has caused rising concerns on the sustainability of lithium and transition metal and the ethic issue around mining practice. Developing alternative energy storage technologies beyond lithium has become a prominent slice of global energy research portfolio.
