Why are lithium metal batteries becoming a solid-state electrolyte?

1. Introduction The growing demand for advanced energy storage systems, emphasizing high safety and energy density, has driven the evolution of lithium metal batteries (LMBs) from liquid-based electrolytes to solid-state electrolytes (SSEs) in recent years.

Can composite electrolytes be used for solid state batteries?

Li metal batteries employing this SSE paired with LiFePO 4 cathodes show 81.56 % capacity retention after 800 cycles at 2 C, demonstrating its potential for commercial solid-state batteries. These findings hold promise for advancing the commercialization of composite electrolytes for solid state batteries. 1. Introduction

Why are SSE batteries important?

SSEs can effectively reduce the risks of batteries associated with thermal runaway and combustion, and mitigate the formation of lithium dendrites , , , , . Moreover, they enable the potential use of lithium metal as the negative electrode, thus further increasing the energy density of the battery , , , , .

Why is mechanical stability important for battery life?

The stress built-up would cause mechanical failure of SEI, resulting in exposure of the fresh anode surface to the electrolyte, consuming the limited active materials and electrolytes, and inducing rapid battery decay. Therefore, understanding and regulating the mechanical stability of SEI is imperative for improving battery cycle life.

Are Li metal batteries safe?

Li metal batteries (LMBs) have attracted considerable attention as next-generation batteries due to their higher energy densities than those of current Li-ion batteries (LIBs) 1, 2, 3. However, the safety issue hinders their practical application in commercial products 4, 5.

What properties are needed to develop high-performance solid-state lithium metal batteries?

Several typical properties are needed to meet the demand for developing high-performance solid-state lithium metal batteries. First, high ionic conductivity (>10 −4 S/cm) is required to ensure favorable electrochemical performance , .
