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...

Background:

Lithium-sulfur (Li-S) batteries offer high energy density for microdevices.
Fabricating solid-state thin-film Li-S batteries (TFLSBs) is challenging due to sulfur's properties.
Existing methods face hurdles with volatility and sluggish kinetics.

Purpose of the Study:

To develop a novel, high-performance all-solid-state thin-film Li-S battery (TFLSB).
To overcome the limitations hindering the integration of Li-S systems into thin-film batteries.
To enable autonomous power for Internet of Things (IoT) microdevices.

Main Methods:

Constructed TFLSBs using a vertical graphene nanosheets-Li2S composite cathode, LiPON solid electrolyte, and Li metal anode.
Employed a solid-state Li-S system with an "unlimited Li" reservoir.
Utilized thin-film fabrication techniques for cathode, electrolyte, and anode.

Main Results:

Achieved excellent long-term cycling stability with 81% capacity retention over 3,000 cycles.
Demonstrated high-temperature tolerance up to 60 °C.
Reported outstanding cycling performance over 500 cycles with 99.71% Coulombic efficiency using evaporated-Li anodes.

Conclusions:

Successfully fabricated TFLSBs by addressing Li-polysulfide shuttle and interface stability.
Presented a new strategy for secure, high-performance rechargeable all-solid-state thin-film batteries.
Highlighted the potential for IoT microdevice autonomy through advanced energy storage solutions.
