Abstract

like carbon sheet/Fe3O4 nanocomposites derived from soda papermaking black liquor for high performance lithium ion batteries, Electrochimica Acta http://dx.doi.org/10. 1016/j.electacta.2017.02.130 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. . Even at a high current density (1000 mA g -1 ), it still exhibits a high reversible capacity (750 mAh g -1 ) after 1400 discharge/charge cycles. More importantly, the removal efficiency of chemical oxygen demand of SPBL is up to 83.4% during the synthesis process, which reduce its load to environment and synthetic cost of carbon-based nanocomposite anodes.

Lignin‐derived electrochemical energy materials and systems

“…For example, the self‐assembled NiO/carbon composites derived from lignin presented excellent porous characteristics and high surface area, and exhibited excellent performance as electrodes for supercapacitors . Meanwhile, lignin was also successfully used to produce graphene‐like carbon sheets, and to obtained the final products of the lamellar graphene‐like carbon / Fe 3 O 4 nanocomposite with homo‐dispersed microstructures . Lignin‐derived MnO 2 / carbon nanofiber mats composite, SiO x / C composite, iron oxide particle / hollow carbon nanofibers nanocomposite, Li 2 NaV 2 (PO 4 ) 3 / hard carbon nanocomposite, core‐shell Si/C composite etc.…”

“…For example, hard carbon prepared from lignin achieved a first discharge capacity of 882.2 mA h g −1 at 0.1 C and remained at a charge capacity of 228.8 mA h g −1 (~92.8% retention ratio) after 200 cycles at 2 C . Alkali lignin and its degradation products were carbonized to form graphene‐like carbon sheet/Fe 3 O 4 nanocomposite anodes, which exhibited an ultra‐high first discharge specific capacity of 3829 mA h g −1 at 50 mA g −1 . In addition, it was reported that a binder‐free Si/C anode exhibited a high specific capacity of 1557 mA h g −1 and was reversibly cycled at 0.54 A g −1 with 89.3% capacity retention over 100 cycles, which can be ascribed to the great role of the lignin‐derived network in suppressing the volume change of Si nanoparticles during cycling .…”

Na3V2(PO4)3/N‐doped Carbon Nanocomposites with Sandwich Structure for Cheap, Ultrahigh‐Rate, and Long‐Life Sodium‐Ion Batteries

“…In addition, it has a three dimensional cross‐linked structure containing C 6 −C 3 hydrophobic basic structure which can be used as an excellent template for synthesis of electrode materials. Our previous studies have revealed that SLS also is a potentially renewable and abundant resource for carbon anode materials ,. We present here a novel Na 3 V 2 (PO 4 ) 3 ultrathin sheet/N‐doping hard carbon ultrathin sheet (NVPUS/NHCUS) nanocomposite with stable sandwich framework.…”

The Surface Coating of Commercial LiFePO4 by Utilizing ZIF-8 for High Electrochemical Performance Lithium Ion Battery

“…As the world’s population grows and the natural non-renewable resource consumes, developing the lithium ion batteries (LIBs) with high electrochemical performances become increasingly important [ 1 – 3 ]. Recently, LIBs with LiFePO 4 (LFP) as cathodes have matured significantly and serviced the markets of modern electronics and electric vehicles [ 4 – 6 ].…”

“…Meanwhile, the sp 2 carbon material is conducive to the transmission of electrons [ 17 ], which may be beneficial to improve the conductive electrode material. Recently, some progress has been made in the surface coating of electrode material by using crystalline carbonaceous material at low temperature [ 1 ]. Moreover, metal elements are also used to improve the electrode conductivity due to their free electrons [ 18 ].…”
