SUMMARY

Research on solid-state electrolytes is increasingly crucial for ensuring the superior energy density and safety of lithium metal batteries. While solid polymer electrolytes (SPEs) offer flexibility and cost-effectiveness, they suffer from low conductivity and modulus, limiting their operation at room temperature and their ability to suppress dendrite formation. In contrast, inorganic solid-state electrolytes excel in conductivity and modulus but are intrinsically brittle and incur high processing costs due to heat and pressure requirements. Solid Composite Electrolytes (SCEs) aim to combine the strengths of both while mitigating their weaknesses, promising advancements in next-generation batteries and bridging gaps in energy storage solutions.

My research focuses on enhancing the performance of SPEs by incorporating a small amount of functionalized inorganic 2D-nanosheet fillers. The addition of these inorganic 2D nanosheets improves the Li-ion transport selectivity and modulus of the electrolyte while effectively suppressing dendrite growth. Furthermore, various types of functional groups, each with its own strategy, were grafted onto the 2D nanosheets to further enhance their mechanical and electrochemical properties.
