Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Dynamic prediction of coal and gas outburst risk based on quantitative analysis of stress–energy evolution and adaptive correction

open access: yesDeep Underground Science and Engineering, EarlyView.
This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.

Hydride Materials for Advanced Electrochemical Energy Storage: Progress and Perspectives

open access: yesEcoEnergy, EarlyView.
Hydrides are emerging as functional materials for low‐carbon electrochemical energy storage. Complex hydrides provide polyanionic electrolyte frameworks for all‐solid‐state, Li–S, and multivalent batteries; hydride ion conductors enable H− transport for emerging hydride‐based cells; and metal hydrides offer established electrode chemistries for Ni–MH ...

Electrolytic (C2CNT) Carbon Nanotubes Made From CO2 as an Inexpensive Carbon Sink and High‐Capacity Li‐Ion Battery Graphite Replacement

open access: yesEcoEnergy, EarlyView.
Carbon‐negative carbon nanotubes produced by molten CO2 electrolysis offer a low‐cost, high‐performance alternative to graphite in Li‐ion battery anodes. Replacing conventional carbon materials with electrolytic CNTs can improve battery capacity and charging performance while reducing costs and contributing to carbon mitigation.

Anode Materials Requirements for Potassium Ion Batteries: Challenges and Future Possibilities

open access: yesEcoEnergy, EarlyView.
This work identifies a critical scale‐up gap between laboratory battery research and industrial targets, driven by low active‐mass loadings and the omission of full‐cell metrics. We outline concrete strategies to bridge this divide, shifting focus toward high‐loading electrodes (> 3 mg cm−2) to ensure practical commercial viability of potassium ion ...
