Optimally Carbonized Mangrove Wood–Derived Hard Carbon with a Soft Carbon Coating for High‐Performance Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
High‐performance SIB anodes are developed using mangrove wood–derived hard carbon, optimized through controlled carbonization temperatures and pitch‐derived soft carbon coatings. The resulting PC‐10 composite achieves a superior reversible capacity of 297.5 mAh g−1 and an 82% ICE by suppressing irreversible reactions and enhancing interfacial stability

Reduction of Periodic Loads on Horizontal Axis Wind Turbines by Multi Harmonics Individual Blade Control

open access: yes, 2018
Horizontal axis wind turbines (HAWTs) are designed for a 20-year or longer activity, hence it is of great interest for the designers the assessment of loads acting on them in the different op- erational conditions.

Recycling Ni‐Rich NCM Cathode Materials From Spent Li‐Ion Batteries as Efficient Electrocatalyst for Urea Oxidation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mounting battery waste demands sustainable solutions. We recycle spent NCM cathodes into high‐performance urea oxidation catalysts, enabling sustainable hydrogen production and simultaneous urea waste treatment. The burgeoning electric vehicle industry has intensified the demand for high‐energy Ni‐Co‐Mn (NCM) cathodes, yet their end‐of‐life management ...

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Architecture of Semiconductive Macroporous Polymer Scaffold to Realize Ultra‐Fast Charging in Lithium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To achieve stable and zero‐expansion Li deposition at high charge rate in lithium metal batteries, a multifunctional macroporous scaffold utilizing the semiconducting properties of PPy is developed. This rationally engineered scaffold enables stable and dendrite‐free plating/stripping without volume expansion even at high current densities of 5 C rate,
