However, many of these systems commonly required operation at elevated temperatures, and / or were expensive to produce, enabling only limited commercial deployment. poly(ethylene) oxide (PEO), and inorganics such as NASICON. This excitement for solid-state electrolytes manifested in the discovery of new systems in both organics, i.e. Most immediately, molten sodium / β - alumina / sulfur cells were developed at Ford Motor Company in the US, and NGK in Japan. In 1967, the discovery of fast ionic conduction β - alumina for a broad class of ions (Li+, Na+, K+, Ag+, and Rb+) kick-started excitement for and the development of new solid-state electrochemical devices with increased energy density. īy the late 1950s, several silver-conducting electrochemical systems employed solid electrolytes, but such systems possessed undesirable qualities, including low energy density and cell voltages, and high internal resistance. History īetween 18, Michael Faraday discovered the solid electrolytes silver sulfide and lead(II) fluoride, which laid the foundation for solid-state ionics. Challenges to widespread adoption include energy and power density, durability, material costs, sensitivity and stability.

Solid-state technology used in these batteries is potentially safer, with higher energy densities, but at a much higher cost. Solid-state batteries have found use in pacemakers, RFID and wearable devices.

Materials proposed for use as solid electrolytes in solid-state batteries include ceramics (e.g., oxides, sulfides, phosphates), and solid polymers. Solid-state technology batteries can provide potential solutions for many problems of liquid Li-ion batteries, such as flammability, limited voltage, unstable solid-electrolyte interphase formation, poor cycling performance and strength.

Developments in the late 20th and early 21st century have caused renewed interest in solid-state battery technologies, especially in the context of electric vehicles, starting in the 2010s. While solid electrolytes were first discovered in the 19th century, several drawbacks have prevented widespread application. ( July 2019)Ī solid-state battery deploys solid-state technology using solid electrodes and a solid electrolyte, instead of the liquid or polymer gel electrolytes found in lithium-ion or lithium polymer batteries.
