Highlights

• Dendrite growth threatens the safety of batteries by piercing the ion-transporting separators between the cathode and anode

• Many problems related to the stability of cathodes and anodes remain to be resolved, more attention needs to be paid to the ion-conducting membranes (ICMs) separating them

• As the industry is continuously pushing for higher energy density, the mechanical properties of internal components become essential as never before. Their brittleness of the Li-based ceramics, reflecting the fundamental conflict between the two essential materials properties[6], makes it difficult to incorporate Li-based ceramics into battery packs. Their safety concerns associated with cracking of ceramic separators necessitate thicker ICMs with increased internal resistance leading to energy losses

Summary

Introduction

Dendrite growth threatens the safety of batteries by piercing the ion-transporting separators between the cathode and anode. Free-standing (PEO/ANF)n membranes were sandwiched between two lithium metal electrodes and housed in a CR2032 coin battery cell. The impregnation with lithium triflate (often used in Li batteries as electrolyte) did not change the mechanical properties of the (PEO/ANF)[200] composite.
