Dandelion Derived Nitrogen-Doped Hollow Carbon Host for Encapsulating Sulfur in Lithium Sulfur Battery

Abstract

Biomass derivative carbonaceous materials are extremely fascinating for developing advanced energy storage devices according to unique architecture. Here, inspired by dandelion with consecutive hollow channel, nitrogen-doped hollow carbon framework (NHCF) as sulfur host was obtained via a simple thermal calcination in ammonia atmosphere for lithium–sulfur battery. The NHCF can effectively confine polysulfides and electrochemical reaction within the hollow channel and expedite lithium ion diffusion and electrode transport through porous nitrogen-doped carbon rampart. With this strategy, a high-level active sulfur loading of 80% and high sulfur utilization can be realized. As a result, the NHCF/S delivered an advanced initial capacity of 950 mAh g–1 at the rate of 0.5 C with small capacity fading rates of 0.049% per cycle after 500 cycles. Additionally, an average reversible areal capacity of nearly 5 mAh cm–2 was realized under raised sulfur mass loading of 5.5 mg cm–2. This superior electrochemical energy storage property endows renewable biomass derived carbon host with promising potential for low-cost rechargeable battery application.

Rambutan peel derived porous carbons for lithium sulfur battery

“…For production of the porous carbons, biomass can become one candidate of the most possible precursors because it is cheap, high abundant, renewable, green and unique porous structures [16][17][18][19][20][21][22][23][24]. Various of biomass has been used as carbons precursors for for Li-S battery system such as avocado shells [25], snake-skin fruit peel [26], hickory shell [27], rapeseed meal [28], moss [29], dandelion [30], banana peel [31], fiber of fern [32], wheat straw [33], mangosteen peel [34], xanthoceras sorbifolia husks [35], goat hair [36], rice husks [37], pistachio shell [38], almond shell [39], waste mandarin peels [17], waste tea [40] and many others [41].…”

“…[1][2][3] The conventional secondary batteries, such as Li-ion, Ni-cadmium, lead-acid batteries, and capacitors are turning out to be hopeful power sources for electric vehicles to overcome these problems. [4][5][6][7][8][9][10][11][12][13][14] However, conventional Li-ion battery shows a less energy density, which is attributed to both the aqueous electrolyte and poor cell voltage of electrode materials.
