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 ...

Deciphering Polarity Effects of Polymer to Regulate Li+ Ionic Environment in Solid Polymer Electrolytes for Solid‐State Lithium Batteries

open access: yesCarbon Energy, EarlyView.
We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...

ALD Derived Li2O Layer Stabilizing Solid Electrolyte Interphase of Silicon/Carbon Anodes for Lithium Storage

open access: yesCarbon Energy, EarlyView.
A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.

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.

Carbonization‐Controlled Porosity and Electron Transport in Molybdenum Oxide‐Carbide/Carbon Nanoflower Anodes

open access: yesEcoEnergy, EarlyView.
Carbonization temperature regulates the pore structure of active materials, leading to distinct pore volumes and particle assemblies of MoO2/Mo2C‐C nanoflower composites. These material‐level structural features determine the degree of interparticle contact within the electrode, and thus, the effective electronic conductivity. The optimized M750 sample
