My research topic is about the deposition behavior of Li ions in Lithium metal batteries, by performing Monte-Carlo simulation with simple model. It has been a long time that many researchers have studied about a Li dendrite problem in batteries, but still this is very challengeable. By performing simulations, I try to find the reason why dendrties are growing in batteries and find how to reduce or suppress the wild growth of dendrites in physical way.

From 2021, I began to work on phase transition with unsupervised machine learning(ML). For complex systems where traditional methods do not work at all, unsupervised ML is a successful technique that can show the phase transition point very accurately. Our target system is various mixtures such as LJ binary mixture, WR mixture, spin-exchange Ising model, polymer blend, PEO+ionic liquids. We suggest new ways to construct proper feature vectors for unsupervised ML techniques and statistical mechanical base of machine learning on phase transition.
