Temperature-dependent Efficiency of Solid-state Batteries: a Comparative Study of Lithium Sulfide, Garnet, and Polymer Electrolytes
Year: 2024
Type: article
Abstract: In this paper we have studied the in-depth comparative examination of the temperature-dependent efficiency of solid-state batteries, concentrating on three primary electrolyte materials: Lithium Sulfide (LiS), Garnet-based electrolytes, and Polymer electrolytes.Solid-state batteries are recognized for their superior safety and energy density; however, their performance is notably affected by the operating temperature.The research models the efficiency of these materials over a temperature spectrum of -10°C to 100°C, employing a parabolic degradation model to accurately reflect the behaviour specific to each material.It is found that Lithium Sulfide maintains the highest efficiency retention at elevated temperatures, rendering it particularly suitable for high-temperature applications.It has also been observed that the Garnet-based electrolytes exhibit moderate stability and efficiency within mid-range temperatures, whereas Polymer electrolytes experience a rapid decline in efficiency when operating outside their optimal temperature range, thus making them more appropriate for low-temperature settings.The paper further explores the practical implications for battery applications, potential design enhancements, and the environmental consequences of temperature-induced degradation.Future research avenues include improving electrolyte stability across broader temperature ranges and investigating hybrid electrolyte systems to enhance thermal performance.
