Unveiling the potential of BCN-Biphenylene monolayer as a high-performance anode material for alkali metal ion batteries: A first-principles study

Schematic diagram of a battery using bpn-BCN monolayer as an anode material. The bpn-BCN monolayer exhibits high specific storage capacities for alkali metals, with values of 1057.33 mA h g −1 for Li, 647.27 mA h g −1 for Na, and 465.98 mA h g −1 for K.
