Why
Hetero-
Interfaces?
The ion/electron behavior in energy devices are affected by the interfaces between components, which determines the overall efficiency.
We believe hetero-interfaces will control the charges in materials & hybrids, which makes a breakthrough in energy devices and our life!
Batteries (2012 - Ongoiong)
Battery
Of Things
Every product has a battery.
We believe our dedication to hetero-interface studies will trigger advanced batteries, as well as a new industrial revolution.
All-solid-state batteries (w/CNU & KIST)
Safety is a prior issue in next-generation batteries.
Engineering of solid-solid hetero-interfaces will give a breakthrough for all-solid-state batteries with high safety.

Thin film all-solid-state batteries (w/KIST)
Thin-film technology allows the systematic study of the interface. It helps us exploring scientific clues for ion and electron dynamics at the hetero-interfaces in all-solid-state batteries.

High E batteries (w/KU)
An increase in energy density of battery is always a top priority.
Hetero-interface studies will provide practical solutions for next-generation Li-S and Li-air batteries.
Soft / Wearable batteries (w/NTU & KAIST)
Soft batteries are in imperative demands for wearable electronics. Hetero-interfaces manipulation makes batteries to be soft and multi-functional – transparent, electrochromic, integrated, or self-healing, as well as be green.
We believe novel batteries will open an era of Battery of Things.
Hydrogen Storage (2014 - 2016)
Solid-state
Composites
Hydrogen is a clean energy carrier.
Hydrogen storage in solid-state materials reduces the tank volume, as well as the safety risk.
Solid-state hydrogen storage in FCEX (w/HMC)
Based on our hetero-interfaces technology and the collaboration with HMC, we reduced the operating temperature of hydrogen storage composites, and confirmed the feasibility of solid-state hydrogen storage materials for FCEV.
Hydrogen Production (2008 - 2014)
Solar
Water
Splitting
Solar hydrogen production from water is the best way to generate a green hydrogen.
Our hetero-interface engineering improves ion and electron transfer at the interface between solid and water, offering efficient photo-catalysts.
