Lithium-ion (Li-ion) batteries are widely used in portable electronic devices, electric vehicles, and grid-scale energy storage systems. Safety of Li-ion batteries, however, has been called into question repeatedly over the past several years due to a conventional organic electrolyte causing fire and explosion in many cases. Ceramic solid-state electrolyte (SSE) thin films promise a viable solution to addressing the safety issue by blocking the lithium dendrite that causes short circuit and thermal runaway, meanwhile offering high energy density for next-generation Li-ion batteries. However, current SSE thin films have low ionic conductivities, ranging from 10-8<\/sup> to 10-5<\/sup> S\/cm, which can be attributed to poor material quality.<\/p>\n

A research team led by Liangbing Hu at the University of Maryland’s A. James Clark School of Engineering recently developed a new method of printing and sintering a variety of SSE thin films. This work, entitled, “Printable, high-performance solid-state electrolyte films,” was published on November 18, 2020, in Science Advances<\/i>. The team named this method “printing and radiative heating” (PRH), which features a solution-based printable technique followed by rapid sintering.<\/p>\n

In a typical process, a precursor suspension is printed on a substrate, whose concentration and thickness can be adjusted. The high-quality and high-performance SSE thin film can then be obtained after rapid (~3 s) high-temperature (~1500\u00b0C) sintering, ensuring minimal Li loss and high crystallinity. This app<\/a>roach not only leads to dense and uniform microstructure for the SSE thin films, but also ensures superior ionic conductivity. Notably, the fabrication process\u2014from precursor to final product\u2014only takes ~5 min, which is ~100 times faster than conventional methods.<\/p>\n

In a proof-of-concept demonstration, the team showed a printed garnet-based SSE thin film to have high ionic conductivity of up to 1 mS\/cm and excellent cycling stability. In addition, the PRH method enables many other designs such as complex multilayer assembly without cross-contamination during synthesis. It can also be extended to preparing other ceramic thin films, which opens up new opportunities in developing safe and high-performance solid-state batteries and other thin-film-based devices.\n <\/p>\n\n
