Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...
MOS Capacitor01:25

MOS Capacitor

A Metal-Oxide-Semiconductor (MOS) capacitor is a fundamental structure used extensively in semiconductor device technology, particularly in the fabrication of integrated circuits and MOSFETs (metal-oxide-semiconductor field-effect transistors). The MOS capacitor consists of three layers: a metal gate, a dielectric oxide, and a semiconductor substrate.
The metal gate is typically made from highly conductive materials such as aluminum or polysilicon. Beneath the metal gate lies a thin layer of...

Summary
This summary is machine-generated.

Hierarchically ordered macro/microporous polyoxometalate-based metal-organic frameworks (3DOM POM@MOFs) were incorporated into solid electrolytes to enhance all-solid-state lithium batteries (ASSLBs). This strategy effectively suppresses lithium dendrites and improves ionic conductivity for safer, high-performance batteries.

Area of Science:

  • Materials Science
  • Electrochemistry
  • Nanotechnology

Background:

  • All-solid-state lithium batteries (ASSLBs) offer enhanced safety and energy density but face challenges with lithium dendrite formation and low ionic conductivity.
  • Polyethylene oxide (PEO) based solid electrolytes are promising but require improvements in ion transport and stability.

Purpose of the Study:

  • To develop a composite solid electrolyte (CSE) for high-performance, dendrite-resistant ASSLBs.
  • To investigate the effect of incorporating hierarchically ordered macro/microporous polyoxometalate-based metal-organic frameworks (3DOM POM@MOFs) into a PEO matrix.

Main Methods:

  • A hard-template method was used to synthesize 3DOM POM@MOFs (specifically 3DOM NENU-3a).
  • 3DOM NENU-3a was incorporated at 1 wt.% into a PEO/lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) system to form the CSE.
  • Electrochemical performance, including ionic conductivity, lithium-ion transference numbers, and electrochemical stability window, was evaluated.

Main Results:

  • The CSE exhibited high ionic conductivity (1.32 × 10-4 S cm-1 at room temperature) and high apparent lithium-ion transference numbers (0.76 at room temperature, 0.89 at 60°C).
  • An expanded electrochemical stability window up to 6.3 V at 60°C was achieved, suppressing lithium dendrite growth.
  • ASSLBs with LiFePO4 and LiNi0.6Mn0.2Co0.2O2 (NMC622) cathodes demonstrated excellent cycling stability and rate performance.

Conclusions:

  • Hierarchically ordered macro/microporous POM@MOF fillers are effective in enhancing the performance of PEO-based solid electrolytes.
  • The developed CSE shows significant potential for creating high-performance, dendrite-resistant ASSLBs.
  • This approach offers a promising strategy for advancing solid-state battery technology.
