Designing composite solid-state electrolytes for high performance lithium ion or lithium metal batteries

Abstract

Solid-state electrolytes (SSEs) are capable of inhibiting the growth of lithium dendrites, demonstrating great potentials in the next-generation lithium-ion batteries (LIBs). However, poor room temperature ionic conductivity and unstable interface...

Recent advancements in solid electrolytes integrated into all-solid-state 2D and 3D lithium-ion microbatteries

“…The solid electrolyte is an important component in the solidstate cell, as in most cases its unsatisfactory bulk and interfacial performance pose the main constraints in the various Li-ion microbattery (LIMBs) technologies' commercialization. 12,14,15 In order to successfully implement the solid electrolyte in the microbattery, it should satisfy the following basic specications: 16,17 High ionic conductivity 10 À4 S m À1 at room temperature 18 (at least >10 À7 S m À1 ) 19 Compared to ionic conductivity, signicantly lower electronic conductivity 20,21 High electrochemical, chemical and thermal stability against electrode materials 19,20 Mechanical integrity to prevent Li dendrites formation 17 Easy synthesis and manufacture on a large scale 22 Low cost and toxicity. Solid electrolytes are typically divided into organic and inorganic types.…”

Molecular Layer Deposition of Crosslinked Polymeric Lithicone for Superior Lithium Metal Anodes

“…Along with an ever-increasing interest in high-energy lithium metal batteries (LMBs) such as lithium-sulfur (Li-S) and lithiumoxygen (Li-O 2 ) batteries in recent years, stable Li metal anodes now are undergoing intensive investigation. A variety of technical strategies have been reported to date, such as three-dimensional (3D) Li-hosting frameworks [3], electrolyte additives [4], solid-state electrolytes [5], and surface coatings [6,7]. Among these efforts, surface coating remains as an facile and effective route, and there have been different inorganic and polymeric coatings developed via wet chemistry and vapor-phase processes [6][7][8][9][10][11].…”

Interfacial Engineering in a Cathode Composite Based on Garnet‐Type Solid‐State Li‐Ion Battery with High Voltage Cycling

“…Further, several reasons were proposed for the larger charge‐transfer/interfacial resistance, e. g., lattice mismatch, space charge layer formation, and inter‐diffusion of elements [39,40,41,32] . Therefore, interfacial engineering is strongly recommended as an effective strategy to dilute the charge‐transfer resistance during the fabrication of the ASSLIB [42,45–49] …”
