Recent advances in lithium solid state batteries

Abstract

The most recent studies of solid state batteries, based on lithium conducting electrolytes and capable of operating at room temperature, are reviewed. This type of battery is of particular technological interest since, theoretically, it possesses high voltage and high specific energy. Unfortunately the known lithium electrolytes have tow specific conductivities and consequently the cells so far developed exhibit high internal resistance. In recent years, however, there has been a great effort to overcome this shortcoming, as pointed out in this paper. The review, therefore, is intended to provide the reader with an entr6e into this particular and important aspect of solid state battery technology.

Developments of Electrolyte Systems for Lithium–Sulfur Batteries: A Review

“…Since the first study on primary solid-state Li-ion batteries in 1972 (Scrosati, 1972), large number of inorganic solid-state electrolytes were investigated for Li-S cells as well as Li-ion batteries, including LiSICON-type phosphates, perovskite-type La (2/3)x Li 3x TiO 3 (LLT), Li 3 N, and Li 4 SiO 4 (Hayashi et al, 2003b;Stramare et al, 2003;Kobayashi et al, 2008;Nagao et al, 2011Nagao et al, , 2013. A list of non-polymer electrolytes, comparing with other electrolytes including polymer electrolytes, ionic liquids, and gel electrolytes, are shown in Figure 6.…”

Digital Printing of Solid‐State Lithium‐Ion Batteries

“…The solid‐state lithium‐ion battery is a long emerging technology whose time has come . By using a solid‐phase lithium‐ion‐conducting electrolyte to achieve the ionic conduction and electronic insulation conventionally performed by an organic liquid electrolyte and separator membrane, solid‐state lithium‐ion batteries may meet the transportation sector's requirements for safety, performance, and durability (Figure ).…”

“…In light of the compelling advantages offered by solid‐state lithium‐ion batteries, it is worthwhile to consider why they have not yet supplanted their liquid electrolyte counterparts. Initially, the greatest challenge was development of a solid electrolyte material with a conductivity comparable with liquid electrolytes [1a]. This obstacle impelled decades of research, and there is now a selection of inorganic, polymeric, and hybrid materials whose bulk resistances approach or match liquid electrolytes [5b,6].…”

Metal-organic chemical vapor deposition enabling all-solid-state Li-ion microbatteries: A short review

“…The all-solid-state architecture was firstly proposed in 1972, on the basis of metallic lithium anodes, (doped) lithium iodide solid-state electrolytes and a metal-iodide based cathode [8]. Since then all-solid-state LIBs were widely investigated.…”
