“…Afterwards, the obtained precursor was ground through ball-milling and subsequently heat-treated at 700 8Cu nder high-purity Ar for 2h at ar amping rate of 10 8Cmin À1 . [17] The obtained black powders were washed several times with deionized water and ethanol to completely remove NaCl, KCl, and other impurities, and then dried at 100 8Cu nder vacuum overnight to remove moisture and yield the Ni/NiS 2 /NSgraphene composites. For comparison, the N-and S-doped graphene composite was also synthesized by using the same approach without the addition of Ni(NO 3 ) 2 ·6H 2 O.…”

The development of sodium-ion batteries (SIBs) is hindered by the rapid reduction in reversible capacity of carbon-based anode materials. Outside-in doping of carbonbased anodes has been extensively explored. Nickel and NiS 2 particles embedded in nitrogen and sulfur codoped porous graphene can significantly improvet he electrochemical performance. Herein abuilt-in heteroatom "self-doping" of albumen-derived graphenef or sodium storage is reported. The built-in sulfur and nitrogen in albumen act as the doping source during the carbonization of proteins. The sulfur-rich proteinsi na lbumen can also guide the doping and nucleation of nickel sulfide nanoparticles. Additionally,t he porous architecture of the carbonized proteins is achieved through removable KCl/NaCl salts (medium) under high-temperature melting conditions. During the carbonizationp rocess, nitrogen can also reduce the carbonization temperature of thermally stable carbon materials. In this work, the NS-graphene delivered as pecific capacity of 108.3 mAh g À1 after 800 cycles under ac onstant current densityo f5 00 mA g À1 . In contrast, the Ni/NiS 2 /NS-graphenem aintained as pecific capacityof134.4 mAh g À1 ;thus the presence of Ni/NiS 2 particles improved the electrochemicalp erformanceo fthe wholec omposite.

Biomass materials are of great interest in high‐energy rechargeable batteries due to their appealing merits of sustainability, environmental benefits, and more importantly, structural/compositional versatilities, abundant functional groups and many other unique physicochemical properties. In this perspective, we provide both overview and prospect on the contributions of biomass‐derived ecomaterials to battery component engineering including binders, separators, polymer electrolytes, electrode hosts, and functional interlayers, and so forth toward high‐stable lithium–ion batteries, lithium–sulfur batteries, lithium–oxygen batteries, and solid state lithium metal batteries. Furthermore, based on the multifunctionalities of bio‐based materials, the design protocols for battery components with desired properties are highlighted. This perspective affords fresh inspiration on the rational designs of biomass‐based materials for advanced lithium‐based batteries, as well as the sustainable development of advanced energy storage devices.

Biomass‐derived carbon materials have received special attention as efficient, low‐cost, active materials for charge‐storage devices, regardless of the power system, such as supercapacitors and rechargeable batteries. In this Minireview, we discuss the influence of biomass‐derived carbonaceous materials as positive or negative electrodes (or both) in high‐energy hybrid lithium‐ion configurations with an organic electrolyte. In such hybrid configurations, the electrochemical activity is completely different to conventional electrical double‐layer capacitors; that is, one of the electrodes undergoes a Faradaic reaction, whilst the counter electrode undergoes a non‐Faradaic reaction, to achieve high energy density. The use of a variety of biomass precursors with different properties, such as surface functionality, the presence of inherent heteroatoms, tailored meso‐/microporosity, high specific surface area, various degrees of crystallization, calcination temperature, and atmosphere, are described in detail. Sodium‐ion capacitors are also discussed, because they are an important alternative to lithium‐ion capacitors, owing to the low abundance and high cost of lithium. The electrochemical performance of carbonaceous electrodes in supercapacitors and rechargeable batteries are not discussed.
