Our laboratory is conducting various research on energy storage and conversion including lihitum ion batteries. In particular, we deal with issues of lithium metal batteries, super capacitors and multivalent ion batteries through the printing process, unique technology of our laboratory. All-Solid-State-Batteries: Improving ion transport properties and thermal stability through the implementation of COF (Covalent Organic Framework) and polymer based soft materials Lithium metal batteries: Understanding of reversible stripping/plating behavior of lithium through 3D host and cellulose based membrane and realization of Anode free lithium metal batteries Printable batteries: Batteries for wearable devices, transparent batteries, and 3D/4D power sources
