It is urgent to explore high-capacity and efficient anode materials for rechargeable lithium-ion batteries. For borophene and phosphorene, two configurations are considered to form a heterojunction: twist angles of 0° (I) and 90° (II).

The stacking battery has more tabs, the shorter the electron transmission distance, and the smaller the resistance, so the internal resistance of the stacking battery can be reduced, and the heat generated by the battery is small. However, winding is prone to problems such as deformation and expansion, which affect the attenuation performance of the battery.
The CDD plot demonstrated that the heterojunction formation was contributed by the electron rearrangement at the stacking interface and the noncontact surface (Figure 14M,N). Figure 14O shows that massive ROS generation resulted

Hence, the overall electrochemical properties of the B/P heterojunction have been enhanced by combining the advantages of the individual phosphorene and borophene monolayers, which guarantees the B/P heterojunction as a good candidate for the anode material used in Li-ion batteries. 1. Introduction
In this work, the B/P heterojunction was constructed as the lattice mismatch between the borophene and the phosphorene monolayer is very small (<4%), and it's expected to show good electrochemical performance as anode materials by combining the advantage of each monolayer.
Herein, a compact heterojunction is designed by embedding half-metallic C (CN) 3 (hm-CN) hydrothermally in BiOBr (BOB) as the backbone. The interface between hm-CN and BOB is seamless and formed by covalent bonding to facilitate the transmission of photoinduced electrons from BOB to hm-CN.
Moreover, the low energy barrier for interlayer migration of Li is observed in configuration I (0.12 eV) and II (0.06 eV), implying its fast kinetic diffusion. In short, the designed B/P heterojunction shows great advantages by comparing with the bare monolayers.
To overcome the obstacles, herein, we report an alternative stacking design of semiconductor heterojunctions on hollow carbon spheres for significantly improved photocatalytic activity, selectivity, and stability in CO 2 -to-CO conversion.
Both I-B/P and II-B/P heterojunctions show metallicity, which is benefit to the electronic conductivity. Li atom can be stably adsorbed in the interlayer of the heterojunction, as well as on the borophene side and the phosphorene side.
