With the increasing role of microelectronics and autonomous wireless devices in everyday life, the miniaturization of power sources has attracted a lot of attention. Solid-state Li-ion microbatteries proved to be a good candidate for micro-energy storage devices due to their high energy density. As the electrolyte is one of the key components in a battery, much research has been conducted to develop high-quality materials for successful integration in the microbattery technology. Several types of solid electrolytes, including inorganic glass, crystalline and polymer materials, have been investigated in both two-dimensional (2D) and three-dimensional (3D) architecture, and these systems are reviewed in this work along with the general overview of microbatteries concepts. The latest advancements, performance and remaining issues of both 2D and 3D solid structures with different solid electrolytes are discussed. The paper also focuses on reviewing the electrochemical properties of solid electrolytes reported in various literature. So far, it was observed that LiPON electrolyte satisfying most of the electrolyte specifications appears to be one of the most studied and the most appropriate candidates for solid-state microbatteries, performing well in several 2D and innovative 3D structures. Along with that, polymer electrolytes with innovative 3D architectures deposited with effective techniques, such as electrodeposition, formed an excellent electrode–electrolyte interface and showed high power and energy densities. Therefore, these electrolytes hold great promise for further 3D microbatteries development. The important information on solid electrolytes and their application in microbatteries is systemized and provided, including the electrolyte composition, ionic conductivity, microbattery electrodes, preparation methods and conditions, architecture, electrochemical test conditions and their performance to elucidate the electrolyte candidates and their microbattery structures with high capacity and long cycle life.

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

New transparent materials for applications as supercapacitors: Manganese-lithium-borate glasses

Small thin-film rechargeable cells have been fabricated with a lithium phosphorus oxyniuide electrolyte, Li metal anode, and Li{sub 1-x}Mn{sub 2}O{sub 4} as the cathode film. The cathode films were fabricated by several different techniques resulting in both crystalline and amorphous films. These were compared by observing the cell discharge behavior. Estimates have been made for the scale-up of such a thin-film battery to meet the specifications for the electric vehicle application. The specific energy, energy density, and cycle life are expected to meet the USABC mid-term criteria. However, the areas of the thin-films needed to fabricate such a cell are very large. The required areas could be greatly reduced by operating the battery at temperatures near 100{degrees}C or by enhancing the lithium ion transport rate in the cathode material.
