Ion Exchange

1.1K
Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Sulfurized polyacrylonitrile (SPAN) is a promising cathode material for lithium-sulfur (Li-S) batteries.
  • Interfacial side reactions and slow redox kinetics hinder SPAN cathode performance.

Purpose of the Study:

  • To stabilize the SPAN cathode electrolyte interphase (CEI) using quaternized chitosan (QCS).
  • To improve the electrochemical performance of Li-S batteries.

Main Methods:

  • QCS was used as a functional agent to modify the CEI of SPAN cathodes.
  • The adsorption of PF6- anions and formation of a LiF-enriched CEI were investigated.
  • Electrochemical performance was evaluated, including discharge capacity, rate capability, and cycle life.

Main Results:

  • The SPAN@QCS-1.0% cathode achieved a high discharge capacity (1499 mAh g-1 at 0.2 C) and rate capability (902 mAh g-1 at 10 C).
  • Extended cycle life exceeding 1500 cycles at 1 C was observed.
  • Under practical conditions (12.0 mg cm-2 sulfur loading, 5 µL mg-1 E/S ratio), a high areal capacity of 17.1 mAh cm-2 was obtained.
  • A 0.9 Ah pouch cell demonstrated stable cycling for over 30 cycles.

Conclusions:

  • QCS effectively stabilizes the SPAN cathode electrolyte interphase, leading to enhanced Li-S battery performance.
  • The interface strategy offers a facile and effective approach for developing high-performance SPAN-based Li-S batteries.
  • This method significantly improves capacity, rate capability, and cycle life, surpassing conventional lithium-ion batteries.
