“…Therefore Li-S batteries have attracted enormous attention worldwide for the next generation of LIBs However, it's well recognised that the commercialization of the Li-S batteries is mainly hindered by the Nano Res. low utilization and rapid capacity decay of the pure sulfur due to three factors: (1) the inherently poor electrical conductivity of sulfur (5 × 10 -30 S/cm at 25 °C ) [4,5]; (2) significant structure and volumetric changes during the charge/discharge process [6]; (3) polysulphides readily dissolve in the organic electrolyte, shuttle to the anode and then react with lithium during the charging process, resulting in deposition of insulating Li 2 S 2 /Li 2 S at the electrode interface and causing electrical and ionic mass transfer blockages [4,5]. Therefore, a variety of strategies including electrolyte development [7], anode modifications [8], inserting an interlayer [9], and cathode synthesis [10][11][12], have been intensively investigated in order to address the above issues in the charge/discharge processes.…”

Being simple, inexpensive, scalable and environmentally friendly, microporous biomass biochars have been attracting enthusiastic attention for application in lithium-sulfur (Li-S) batteries. Herein, porous bamboo biochar is activated via a KOH/annealing process that creates a microporous structure, boosts surface area and enhances electronic conductivity. The treated sample is used to encapsulate sulfur to prepare a microporous bamboo carbon-sulfur (BC-S) nanocomposite for use as the cathode for Li-S batteries for the first time. The BC-S nanocomposite with 50 wt.% sulfur content delivers a high initial capacity of 1,295 mA·h/g at a low discharge rate of 160 mA/g and high capacity retention of 550 mA·h/g after 150 cycles at a high discharge rate of 800 mA/g with excellent coulombic efficiency (≥95%). This suggests that the BC-S nanocomposite could be a promising cathode material for Li-S batteries.

“…For lithium-sulfur battery applications, these C/S composites are able to manipulate 'shuttle effects' for better stability, while larger pores to facilitate ion transportation for improving rate performance. To date, all kinds of biomass precursors, such as pig bone [142], fish scales [66], shrimp shell [143], litchi shells [144], olive stones [145], cotton [146], silk cocoon [147], bamboo [148], wheat straw [149], mango stone [150], pomelo peels [151], banana peels [152], gelatin [153], cassava [154], bark of plane trees [155], starch [156], have been widely explored to prepare hierarchical porous carbons by well-deigned carbonization processes. All of these biomass-derived hierarchical carbons can be used as conductive host of sulfur for lithium-sulfur battery with improved electrochemical performances.…”

Electrochemical energy storage devices, such as supercapacitors and batteries, have been proven to be the most effective energy conversion and storage technologies for practical application. However, further development of these energy storage devices is hindered by their poor electrode performance. Carbon materials used in supercapacitors and batteries are often derived from nonrenewable resources under harsh environments. Naturally abundant biomass is a green, alternative carbon source with many desired properties. This review article presents state of the art of renewable carbon materials derived from natural biomasses with an emphasis on their applications in supercapacitors and lithium-sulfur batteries. IMPACT STATEMENTThis review paper provides a comprehensive understanding for obtaining renewable carbons from natural biomass precursors via various activation methods for electrochemical energy storage application, especially for supercapacitor and lithium sulfur battery.

“…Activated carbon is the most widely used active material for the EDLC electrodes due to its high surface area and relatively low cost [15]. Carbon materials for electrochemical energy storage devices are mainly derived from biomass [16][17][18][19]. At the same time, new types of electrolytes were studied, with the aim to increase the operative voltage of EDLC devices as a consequence of high conductivity and excellent electrochemical stability of these electrolytes [20,21].…”

In the present work, the cellulose-based materials were manufactured and used as components of electrochemical double layer capacitors (EDLCs). The preparation method of cellulose membranes as well as composite electrodes containing cellulose as a binder was presented. These materials were prepared using for the first time ionic liquid/dimethyl sulfoxide (IL/DMSO) mixture solvent. Obtained components displayed a uniform structure, thermal stability, and good electrochemical properties. The electrochemical performances of these materials were studied in 2-electrode EDLC cells by common electrochemical techniques as cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS). The composite electrodes were investigated in three types of electrolytes: aqueous, organic, and ionic liquids. The cellulose membranes were, however, soaked in an aqueous electrolyte and tested as hydrogel polymer electrolytes. All investigated materials show high efficiency in terms of specific capacity. The studied cellulose-based capacitors exhibited specific capacitance values in the range of 20-22 F g −1 , depending on the type of applied electrolyte.
