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:

All-solid-state lithium batteries (ASSLBs) offer enhanced safety and energy density over conventional lithium-ion batteries.
Sulfide solid electrolytes are attractive due to high ionic conductivity and ductility, enabling better interfacial contact.
Increasing active material loading in composite cathodes is crucial for boosting ASSLB energy density.

Purpose of the Study:

To investigate Ni-rich LiNi_xCo_yMn_1-x-yO₂ (NCM) materials as cathode active materials for high-energy-density ASSLBs.
To determine the optimal NCM properties (Ni content, particle size, crystalline form) for high-performance ASSLBs.
To evaluate cathode performance at high active mass loading.

Main Methods:

Synthesis and characterization of Ni-rich NCM materials with varying Ni content, particle size, and crystalline structure.
Fabrication of ASSLB cells using sulfide solid electrolytes and high mass-loaded composite cathodes.
Electrochemical testing, including cycling performance, rate capability, and capacity retention measurements.

Main Results:

Single-crystalline LiNi_0.82Co_0.10Mn_0.08O₂ with a small particle size showed the best cycling performance.
The optimized cathode achieved a high active mass loading of 26 mg cm^-2 and an areal capacity of 5.0 mAh cm^-2.
Excellent discharge capacity, capacity retention, and rate capability were observed for the optimized ASSLB.

Conclusions:

Single-crystalline, small-particle LiNi_0.82Co_0.10Mn_0.08O₂ is a highly promising cathode material for high-energy-density ASSLBs.
Achieving high active mass loading is feasible with optimized cathode materials and solid electrolytes.
This research contributes to the development of safer and more energy-dense solid-state batteries.
