Deriving battery grade materials from natural sources is a key element to establishing sustainable energy storage technologies. In this work, we present the use of avocado peels as a sustainable source for conversion into hard carbon based anodes for sodium ion batteries. The avocado peels are simply washed and dried then proceeded to a high temperature conversion step. Materials characterization reveals conversion of the avocado peels in high purity, highly porous hard carbon powders. When prepared as anode materials they show to the capability to reversibly store and release sodium ions. The hard carbon-based electrodes exhibit excellent cycling performance, namely, a reversible capacity of 352.55 mAh/g at 0.05 A/g, rate capability up to 86 mAh/g at 3500 mA/g, capacity retention of >90%, and 99.9% coulombic efficiencies after 500 cycles. This study demonstrates avocado derived hard carbon as a sustainable source that can provide excellent electrochemical and battery performance as anodes in sodium ion batteries.

Recently, sodium ion batteries have attracted considerable interest for large-scale electric energy storage as an alternative to lithium ion batteries. However, the development of anode materials with long cycle life, high rate, and high reversible capacity is necessary for the advancement of sodium ion batteries. Bi anode is a promising candidate for sodium ion batteries due to its high theoretical capacity (385 mAh g–1 or 3800 mAh l–1) and high electrical conductivity (7.7 × 105 S m –1). Herein, we report the preparation of Bi anode using micro-sized commercial Bi particles. DME-based electrolyte was used, which is well known for its high ionic conductivity. The Bi anode showed excellent rate-capability up to 16 C-rate, and long cycle life stability with a high reversible capacity of 354 mAh g–1 at 16 C-rate for 50 cycles.

Sodium-ion batteries (SIBs) have been regarded as one of the most competitive alternatives for lithium-ion batteries (LIBs) due to the abundance of sodium and comparable electrochemical characteristics of sodium to that of lithium. However, while highly desired, developing stable anode materials remains a critical challenge. In this work, the development of a stable anode for SIBs is reported, a poriferous nanoflake-assembled flower-like nickel tetraphosphide (PNAF-NP) with high surface area and typical mesoporous property. Due to the unique structure, the PANF-NP anode exhibits excellent reversible capacity of 648.34 mAh g-1 at 0.2 A g-1 with a Coulombic efficiency of 98.67%, and superior cycling stability at 0.2 A g-1 with high retention capacity of 456.34 mAh g-1 and average Coulombic efficiency of 99.19% after 300 cycles. Moreover, the high reversible capacity of 614.43, 589.49, 512.66, and 432.23 mAh g-1 is achieved at 0.5, 1, 2, and 5 A g-1, respectively, indicating the superior rate capability of the PNAF-NP anode. This work represents a great advancement in the field of SIBs by reporting a high-performance anode material.
