A New Quantitative Analysis Method for Overvoltage in Sending End Electric Power System With UHVDC

IEEE Access, 2020
With the development of renewable electric power generation and ultra-high voltage direct current (UHVDC) transmission, the transient overvoltage in the sending end electric power system with UHVDC occurs, but it is lack of quantitative transient voltage

Optimization-Based Mitigation Techniques of the Temporary Overvoltage in Large Offshore Wind Farm

IEEE Access, 2023
Overvoltage transient is the major danger facing large offshore wind farms, as it may lead to a complete failure of the system components. A 150 MW offshore wind farm was modeled using the ATP-EMTP package to analyze the effect of the temporary ...

Na5FeS4 as High‐Capacity Positive Electrode Active Material for All‐Solid‐State Sodium Batteries

Batteries &Supercaps, EarlyView.
All‐solid‐state sodium cells using Na5FeS4, synthesize through a simple and scalable process using sodium polysulfides, as a positive electrode active material exhibit a high reversible capacity of 480 mAh g−¹, which is attributed to the sufficiently high ionic conductivity of the active material and the maintenance of the active material/solid ...

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...
