Research focused on
The primary focus of our research is the design and development of low-cost, efficient, long-life materials that can facilitate widespread commercialization for various applications such as rechargeable batteries, supercapacitors, fuel cells, chemical gas sensors and biomedical field.
Rechargeable batteries
A rechargeable battery, storage battery, or secondary cell, is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. We have been working on solid electrolytes (NASICON-type, and Garnet-type) and electrode materials for all solid state LIBs and SIBs.
Supercapacitor
A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor with a capacitance value much higher than other capacitors, but with lower voltage limits, that bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries. We have been developing many porous high entropy metal oxides and nanocomposites for hybrid aqueous and all solid state supercapacitors. A real-world usage of the our hybrid device is examined by enlightening the red light-emitting diode (LED).
Chemical gas sensors
Gas sensors are chemical sensors, i.e. devices that transform chemical information, which is the concentration of one or several analyte gases, into an analytically useful signal. The development of cost-effective, highly sensitive and reliable NOx gas sensor is really challenging. We have been working to develop simple, highly sensitive and reliable NOx gas sensor with metal oxides-rGO nanocomposites by using ac impedance method.
Bioceramics
Bioceramics are ceramic materials specially developed for use as medical and dental implants. They are usually used to replace hard tissue in the body like bone and teeth. Common bioceramics are alumina, zirconia and a form of calcium phosphate known as hydroxyapatite. We have been fabricating various therapeutic ions embedded bioceramics for biomedical application.
