Summary
Conductive polymers synthesized via electropolymerisation effectively mitigate the shuttle effect in lithium-sulphur batteries (LiSBs). This research explores their application in cathodes, anodes, separators, and electrolytes for improved energy storage.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Lithium-sulphur batteries (LiSBs) offer high theoretical energy density and cost-effectiveness.
- The practical application of LiSBs is hindered by the lithium polysulphide (LPS) shuttle effect.
- Conductive polymers show promise in addressing the shuttle effect due to their conductivity and LPS affinity.
Purpose of the Study:
- To systematically investigate conductive polymers prepared by electropolymerisation (EP) for LiSB applications.
- To evaluate the role of EP-derived conductive polymers in various LiSB components (cathodes, anodes, separators, electrolytes).
- To discuss the broader potential of EP technology in next-generation batteries.
Main Methods:
- Electropolymerisation (EP) technique used for synthesizing conductive polymers.
- Systematic investigation of EP-derived conductive polymers in LiSB components.
- Analysis of conductive polymer performance in mitigating the shuttle effect.
Main Results:
- Conductive polymers prepared via EP demonstrate effectiveness in alleviating the shuttle effect in LiSBs.
- EP-derived polymers show versatile applications across cathodes, anodes, separators, and electrolytes.
- Improved electrical conductivity, mechanical flexibility, and LPS affinity were observed.
Conclusions:
- Electropolymerisation is a viable and sophisticated method for preparing conductive polymers for LiSBs.
- Conductive polymers significantly enhance LiSB performance by controlling the shuttle effect.
- EP technology holds substantial potential for advancing future energy storage solutions.

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...

Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.

In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...
