Snse Nanoplates Swallowed in Carbon Nanofibers As the Self-Standing Anode for Lithium-Ion and Sodium Batteries with Enhanced Performance

SnSe is a promising anode candidate for both lithium-ion and sodium batteries (LIBs and SIBs) with high theoretic capacities, low toxicity and abundant resources. However, it suffers a short cycling life due to the poor conductivity and volume expansion when used as anode material. To improve its Li/Na storage properties, SnSe nanoplates are encap-sulated in carbon nanofibers formation a 3D conductive network via a moderate electro-static spinning and heat treatment. The modified SnSe anode exhibits textile-like feature with extensively mechanical flexibility, and was directly used as anode without and ad-ditives for both LIBs and SIBs. It delivers an excellent cycle performance with a high ca-pacity (598 mA h g-1 after 400 cycles for LIBs and 240 mA h g-1 after 250 cycles for SIBs), which are modify enhanced comparing with reported works. The effective strategy can provide an available approach to build self-standing and flexible architecture, which is beneficial for the design of electrode materials for SIBs.(c) 2022 Hydrogen Energy Publications LLC.
