Title: Yanyi Liu and Nanofiber-Based Energy Technologies.

Introduction

Yanyi Liu is an inventor associated with Beijing, China, whose patent work focuses on nanofiber-based solid electrolytes for oxygen sensors and fuel cells. The supplied information lists 2 patents and identifies Toyota Jidosha Kabushiki Kaisha and Tsinghua University among her professional affiliations.

Latest Patents

Liu’s listed inventions describe methods for producing solid electrolyte materials from metal-oxide nanofibers. Both methods begin by spinning a precursor made from a solvent, a macromolecular polymer, and a salt of one or more specified metals. The precursor is then calcined at 550–650°C for two to four hours, producing nanofibers that form the solid electrolyte material.

The patent titled “Method for Producing Oxygen Sensor” applies this material to an oxygen sensor. The nanofiber-based solid electrolyte constitutes part of the sensor, linking the production process to a functional sensing component.

The patent titled “Method for Producing Fuel Cell Including Nanofibers of Metal Oxide” uses a similar process to make a solid electrolyte for a fuel cell. In this application, the resulting nanofiber material constitutes part of the fuel cell.

Career Highlights

The supplied career information connects Liu with Toyota Jidosha Kabushiki Kaisha and Tsinghua University. Her listed patent inventions address materials and manufacturing methods relevant to both sensing technology and fuel-cell systems.
