Black phosphorus-arsenic alloys for lithium ion batteries

Original language description

Phosphorus and arsenic belong to the 5th group of elements - so-called pnictogens. These materials are among the most intensively studied nanomaterials with layered structure. In this contribution we report the synthesis of arsenic - black phosphorus alloys. Two samples with various black phosphorus and arsenic content together with pure black phosphorus were exfoliated using shear force milling. Extensive analyses have revealed the successful synthesis of AsP alloys with good crystallinity and composition close to that of the intended value. Testing these materials for lithium ion batteries (LIBs) shows that there is a huge capacity loss after the initial charge/discharge cycles. Such a drop was attributed to a delithiation of the lithium rich phase and a loss of proper electrical contact. After the initial capacity loss, the Coulombic efficiencies in the subsequent cycles reached 90-99%. Moreover, both of the alloys exhibited higher capacity than pure black phosphorus sample, indicating that alloying with arsenic is an advantageous technique. The results of this work show the fundamental charge storage capabilities of AsP alloys a can serve as a starting point for the synthesis of advanced materials based on AsP alloys.
