Chen, Jing (author), Liu, X. (author), Zeng, Xiao Liang (author), Ye, Huai Yu (author), Zhang, Kouchi (author)Hexagonal boron nitride (BN) is often used as filler to improve the thermal conductivity of polymer matrix due to its high thermal conductivity. However, previously reported BN-based composites always have a high in-plane thermal conductivity, which is not beneficial for vertical heat dissipation. In addition, high BN content results in the...journal article 2022

Liu, M. (author), Zhang, S. (author), van Eck, Ernst R.H. (author), Wang, C. (author), Ganapathy, S. (author), Wagemaker, M. (author)The development of commercial solid-state batteries has to date been hindered by the individual limitations of inorganic and organic solid electrolytes, motivating hybrid concepts. However, the room-temperature conductivity of hybrid solid electrolytes is still insufficient to support the required battery performance. A key challenge is to...journal article 2022
