Exploring the Mechanism of the Electrochemical Polymerization of CO2 to hard carbon over CeO2 (110) [PDF]

open access: yes, 2023
Conversion of CO2 to hard carbon is an interesting technology for the removal of carbon dioxide from the atmosphere. Recently, it was shown that CeO2 can selectively catalyse this reaction but we still lack information regarding the reaction mechanism ...

Effects of Excessive Prelithiation on Full-Cell Performance of Li-Ion Batteries with a Hard-Carbon/Nanosized-Si Composite Anode

open access: yesBatteries, 2022
The effects of excessive prelithiation on the full-cell performance of Li-ion batteries (LIBs) with a hard-carbon/nanosized-Si (HC/N-Si) composite anode were investigated; HC and N-Si simply mixed at mass ratios of 9:1 and 8:2 were analyzed.

Capacitance-enhanced sodium-ion storage in nitrogen-rich hard carbon [PDF]

open access: yes, 2017
We demonstrate an approach to prepare nitrogen-rich hard carbon (N-HCS) from biomass as a robust anode material for sodium-ion batteries. A reversible capacity of similar to 520 mA h g(-1) at a current density of 20 mA g(-1) along with an excellent rate ...

Electrochemical intercalation of rubidium into graphite, hard carbon, and soft carbon

open access: yesChemical Science, 2023
The electrochemical intercalation of Rb into graphite and low-crystalline carbons was demonstrated. It was confirmed that stage-1 RbC8 was formed in the low-potential region close to the Rb plating potential (Rb+/Rb) in non-aqueous electrolytes.
