Flash Lamp Annealing Enables Thin-Film Solid-State Batteries on Aluminum Foil
نویسندگان
چکیده
Crystallization of cathode films in solid-state microbatteries requires thermal annealing at high temperatures, restricting the choice substrate and current collector materials. Here, flash lamp (FLA) is explored to crystallize LiCoO2 (LCO) cathodes on aluminum foils. Millisecond pulses visible light induce rapid heating LCO up 900 °C, whereas never exceeds melting point. Microbatteries consisting an FLA-processed cathode, a LiPON electrolyte, Li metal anode are fabricated flexible foil, with performance comparable those rigid silicon. This method can enable new microbattery designs lower production costs.

Ii. Solid State Thin Film Lithium Batteries
Solid state thin film lithium microbatteries fabricated by pulsed-laser deposition (PLD) are suggested. During deposition the following process parameters must be considered, which are laser energy and fluence, laser pulse duration, laser pulse frequency, target composition, background gasses, substrate temperature, target-substrate distance and orientation. The effects of the variations of the...
متن کاملSurface/Interface Effects on High-Performance Thin-Film All-Solid-State Li-Ion Batteries.
The further development of all-solid-state batteries is still limited by the understanding/engineering of the interfaces formed upon cycling. Here, we correlate the morphological, chemical, and electrical changes of the surface of thin-film devices with Al negative electrodes. The stable Al-Li-O alloy formed at the stress-free surface of the electrode causes rapid capacity fade, from 48.0 to 41...
متن کاملNew Developments in Solid Electrolytes for Thin-Film Lithium Batteries
Research on lithium-ion secondary batteries began in the 1980s because of the growing demand for power sources for portable electronic devices. After the early 1990s, the demands for higher capacities and even smaller sizes energy systems significantly increased. Further, the explosive growth in the use of limited fossil fuels and their associated environmental issues and economical aspects are...
متن کاملThermal effects in thin-film organic solid-state lasers.
With the recent development of organic solid-state lasers (OSSLs) architectures enabling power scaling and progresses towards continuous-wave operation, the question of thermal effects now arises in OSSLs. In this paper, a Rhodamine 640-PMMA based vertical external cavity surface emitting organic laser is investigated. A thermal microscope is used to record temperature maps at the organic thin ...
متن کاملElectrochemical protection of thin film electrodes in solid state nanopores.
Solid state nanopores are a core element of next-generation single molecule tools in the field of nano-biotechnology. Thin film electrodes integrated into a pore can interact with charges and fields within the pore. In order to keep the nanopore open and thus functional electrochemically induced surface alteration of electrode surfaces and bubble formation inside the pore have to be eliminated....
