Mass Production of Waste PVC‐Mediated Bamboo‐Derived Hard Carbon for Ultra‐Long Life Sodium Storage

open access: yesCarbon Energy, EarlyView.
By a scalable PVC‐mediated bifunctional strategy, pre‐carbonized micrometer bamboo powder is converted into a functionally partitioned hard carbon anode with distinct domains. Featuring abundant internal closed pores and surface sp2‐enriched graphitic regions, this anode delivers exceptional high‐rate long‐cycle stability, retaining 93% capacity after ...

Interfacial Electronic Coupling in the GeSe2/Volcanic‐Rock–Like Carbon Framework Activates Reversible Intermediate Conversion for High‐Rate Sodium Storage

open access: yesCarbon Energy, EarlyView.
A combined sol–gel/solid‐state approach was developed to integrate GeSe2 with a “volcanic‐rock”–like carbon framework (C). C incorporation reactivates the otherwise irreversible intermediates Na2Ge2Se5 and Na2GeSe3, thereby suppressing irreversible Na+ consumption.

Multiple Synergistic Effects Enabling Efficient Kesterite Solar Cells via Introducing a Cu2O‐Bi2O3 Sacrificial Interlayer

open access: yesCarbon Energy, EarlyView.
The Cu2O‐Bi2O3 thin film as a sacrificial interlayer at the back contact of kesterite solar cells achieves multiple synergistic optimizations in bulk defects, interface defects, back‐contact band offset, and MoSe2 properties. This enhances carrier separation, suppresses interface recombination, and enables DMSO‐processed kesterite devices to reach a ...
