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.

A new layered Na0.3MoO2 exhibits a reversible capacity of 146 mA h g−1, remarkable cycling stability and good rate capability for sodium half-cells. And a Na0.3MoO2//Na0.8Ni0.4Ti0.6O2 full intercalation-type sodium-ion cell is fabricated and it displays an excellent cycling stability. These results indicate that molybdenum-based oxide is a promising anode material for sodium-ion batteries.

As a kind of common bio-waste, willow catkin is of no economic value. But it is surprising that it can be an ideal carbonaceous source and bio-template for electrode materials of lithium-ion batteries and supercapacitors. Herein, we demonstrate that microtubular hard carbon can be derived from willow catkins and used as an anode of sodium-ion batteries (SIBs). The sample obtained from carbonization at 1000 °C delivers a high reversible capacity of 210 mAh g−1, good rate capability, and excellent cycling stability (112 mAh g−1 at 1000 mA g−1 after 1600 cycles) due to its unique tubular structure and the N-doping characteristic. The present work affords a new candidate for the production of hard carbon materials with tubular microstructure using natural biomass, and develops a highly promising anode material for SIBs.
