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...

To predict future research trends in LSB separator functionalization.

Main Methods:

Review of existing literature on separator functionalization techniques for LSBs.
Analysis of how barrier layers within separators address polysulfide migration.
Evaluation of the impact of these modifications on battery performance metrics.

Main Results:

Separator functionalization effectively creates a barrier against polysulfide ion diffusion.
This approach improves the utilization of active materials and enhances overall battery cycle stability.
Modified separators contribute to prolonged cycle life and better Coulombic efficiency in LSBs.

Conclusions:

Functionalizing the separator is a highly effective strategy to overcome the shuttle effect in LSBs.
Continued research into separator modification holds significant potential for advancing LSB technology.
This review highlights separator functionalization as a key pathway for realizing the commercial viability of LSBs.
