Niobium NaSICON paper published in J. Mater. Chem. A

9 Feb 2023

Biplab’s paper, with contributions from Debolina Deb of the group, on using a Niobium sodium superionic conductor (NaSICON) framework as an anode for Li- and Na-ion batteries, was published today in Journal of Materials Chemistry A. The study demonstrates electrochemically that an `empty’ Nb2(PO4)3 framework can reversibly intercalate Li and Na ions, at 1.86 V and 1.46 V vs. the corresponding metallic states, respectively, resulting in possible use as an anode in Li-ion and Na-ion battery frameworks. We correlated the phase behavior and average voltage in Na-intercalation Nb2(PO4)3. The work was led by Prof. Premkumar Senguttuvan of the New Chemistry Unit, Jawaharlal Nehru Centre for Advanced Scientific Research, in collaboration with Prof. Sai Gautam Gopalakrishnan.
