Research Field
Cathode & Anode
1) High nickel NCM
2) LFP
● LFP/C coating with BaTiO3
✔️ The nano-sized ferroelectric ceramic material Barium Titanate (BaTiO3) has been reported to
exhibit high-rate performance in NCM and LCO due to the improvement of low ionic conductivity
during surface modification, along with enhanced lithium-ion conductivity.
3) Dry Process Electrode
4) Complexation Li metal and Graphite for pre-lithiation
● Unlike traditional prelithiation strategies that use additional solvents, gases, and additives,
direct prelithiation reaction in dry conditions, which can be a simple process and avoids
unwanted side reactions.
● By complexing Li metal in the electrode, Li loss is compensated even in the solid state,
improving initial CE and improving cyclability.
● Additionally, the added Li metal chip serves as an additional reservoir to offset the loss of active
Li due to anode degradation during cycling.
ASSBs (All-solide state battery)
1) MLCB (Multi layer ceramic battery)
● MLCB has the same manufacturing process as MLCC, but the materials used are battery
materials such as anode, solid electrolyte, and cathode.
● Hundreds to thousands of MLCCs mounted on a PCB can be replaced with one MLCB.
● MLCB has the advantages of high reliability and stability, ultra-small device,
excellent thermal/mechanical stability, and eco-friendly device.
● The only company currently mass-producing it is TDK, and this product has a low voltage of 1.5V.
● MLCB of 3.0V or higher is under decelopment
2) Cathode/Anode : LVP (Li3V2(PO4)3
● LVP is used as a cathode and anode and can be applied to non-polar batteries.
3) Solid State Electrolyte : LBA (Li2O-B2O3-Al2O3
● LBA is glass type solid electrolyte with a low sintering temperature.
▶ Our Laboratory is conducting research on MLCB based on TDK's patents
4) Hybrid polymer electrolyte

● Improvement for polymer electrolyte
● In-situ thermal gelation of PVA-CN gel polymer electrolyte
→ Extraordinary electrochemical performence via novel polymerization mechanism of PVA-CN
monomer
→ PVA-CN gel used as polymer matrix in HPE
● Hybrid polymer electrolyte (HPE)
→ Ceramic filler enhances polymer electrolyte for high performance Li-ion batteries
→ Boosting Li+ conductivity
→ Enhanced mechanical properties
→ Improved stability at high voltages
Sodium all solide state battery
● All-Solid-State Batteries (ASSBs) using sodium as guest ions have been proposed.
● Sodium Ion Batteries (SIBs) are attractive in terms of abundance and cost.
● As future research, our laboratory plans to conduct research on a stacked sodium all-solid-state battery using sodium, which can replace Li, in combination with the MLCB currently being studied.
