Our research group, BEE Lab., is conducting multiscale research on a variety of next-generation rechargeable batteries via engineering of negative electrodes, functionalization of electrolyte/separator, and development of Beyond-Li batteries.
Research Themes
Advanced Negative Electrodes
for Energy-dense Lithium-ion Batteries
Pure Si anodes have emerged as a viable solution to boost the energy density of LIBs. In this perspective, we propose a unique molecular-scale design of Si anodes and highly integrating polymeric binders based on a new material chemistry.

Dual-ion Batteries
for 'next level' energy storage systems
Deviated from the Conventional cation-driven charge storage, Dual-ion batteries provide multiple choices for charge storage mechanism and thus can be shaped for different energy applications that require fast-charging capability, sustainability, high-energy-density, or long-term service life.

Beyond-Li & Organic Batteries
for Sustainable Future Technology
Sustainability of rechargeable batteries is increasingly important to our ecosystem and mankind as it reduces the carbon footprint at the beginning of their manufacturing. To this end, we are shifting ourselves to alternative battery materials such as multivalent metals, relatively earth-abundant Na/K metals, organic electrodes, and aqueous electrolytes.

Functional Electrolyte/Separator
for Safe/fast Lithium-ion and Li Metal Batteries
Electrolytes occupy the pore structure of the separator and this electrolyte-reservoir determines diffusion characteristics inside the battery. We propose an ion-accelerated, functionalized, and safety-enhanced liquid/solid structure.
