Facile Development of Disused Nickel Foams into Low-Cost and High-Performance Electrode Materials for Sodium-Ion Batteries

Abstract

Ni-based selenide has flourished as one of the most competitive anode materials for sodium-ion batteries due to its low cost, wide source, and high theoretical specific capacity. As one of the members, NiSe microparticles with the sizes of 2.0−10.6 μm are synthesized with disused nickel foam fragments by a facile and rapid one-step selenization method, possessing a prominent rate capability of 304.3 mAh g −1 at 15 A g −1 and a remarkable lifespan with 291.7 mAh g −1 after 1600 cycles at 2 A g −1 . A Na 3 V 2 (PO 4 ) 2 F 3 @reduced graphene oxide//NiSe full cell also exhibits excellent sodium storage behavior and potential utility, achieving the largest power density of 1919.0 W Kg −1 , the highest energy density of 146.0 Wh kg −1 , and a capacity of 119.7 mAh g −1 after 600 cycles at 1 A g −1 accompanied by impressive Coulombic efficiency (>95%, except for the first two cycles). The reversible phase transition, proper use of the ether electrolyte, low electrochemical impedance, and favorable structural stability all synergistically contribute to the satisfactory electrochemical property of NiSe. This work effectively improves the preparation efficiency of NiSe, tendering a new synthetic route for the anode materials.

Towards metal selenides: a promising anode for sodium-ion batteries

“…Along with this strategy, NiSe was synthesized by adjusting the calcination temperature and time, resulting in splendid rate performance (304.3 mA h g −1 at 15 A g −1 ) and brilliant long-term cyclability (291.7 mA h g −1 after 1600 cycles at 2 A g −1 ). 53 This fully demonstrates the universality of preparing metal selenides through this strategy. In addition, the stable reversible phase transition during the Na + storage process is characterized by ex situ strategies in these works.…”

“…Inspired by the successful synthesis of Cu 2 Se, we subsequently prepared a carbon-free ZnSe from waste zinc foil using a simple solid-phase method. 54 Similarly, we synthesized NiSe 53 and NiSe 2 52 from waste nickel foam using the same approach. As expected, by optimizing the experimental conditions, excellent rate capability and cycling performance can be obtained for all materials.…”
