“…At present, mainly two different compounds were studied: TM 2 SnO 4 (with TM = Co, [175][176][177][178][179][180][181][182] Ni, 183 or Mn 182,184,185 ) and TMSnO 3 (with TM = Co [186][187][188][189][190] or Ni 191,192 ). Depending on the comprised TM, spinel-structured TM 2 SnO 4 and (frequently amorphous) TMSnO 3 offer specific capacities exceeding 1100 mA h g À1 and 1200 mA h g À1 , respectively (see Table 1), when considering the second step of the following reaction mechanism as fully reversible:…”

“…Chitosan has recently been used in Li-ion batteries for various purposes; in a previous study, we used chitosan as a binder for the cathode active material 27 . Chitosan has also been used as a template during the synthesis of active material, as a carbon source 28 , as a binder for several anode materials, and as a gel polymer electrolyte 29,30 .…”

A facile strategy to entrap milled silicon (m-Si) particles using nitrogen-doped-carbon (N-C@m-Si) to overcome the dramatic volume changes in Si during intercalation of lithium ions and to improve its electronic conductivity is reported here. The only natural nitrogen containing biomaterial alkaline polysaccharide, i.e., chitosan, is used as the carbon source. Simple hydrothermal technique followed by a subsequent carbonization process is used to synthesize N-C and N-C@m-Si particles. N-C@m-Si exhibited significantly improved electrochemical performance as compared to bare m-Si, which is confirmed by the obtained discharge capacity of 942.4 mAh g −1 and columbic efficiency of 97% after 50 cycles at 0.1C rate. With regard to the N-C electrodes, the obtained discharge capacity of 485.34 mAh g −1 and columbic efficiency of 99.78%, after 50 cycles at 0.1C rate is superior to the commercial graphite electrodes. The solid electrolyte interphase (SEI) layer that formed over m-Si and N-C@m-Si electrodes is characterized using X-ray photoelectron spectroscopy. Compared to the SEI layer that formed over m-Si electrode after 10 charge-discharge cycles, the N-C@m-Si electrode had a stable lithium fluoride and carbonate species. Brief reaction mechanisms, representing the formation of different species in the SEI layer, is derived to explain its behavior during the electrochemical processes.

“…These attractive characteristics have spurred the utilization of hydrochar as precursor of activated carbons with high performance as supercapacitor electrodes [32][33][34][35], hydrogen stores [18] or CO 2 capture sorbents [31,36,37]. It is worth noting that the hydrothermal carbonization process has risen also as an attractive procedure for producing carbon shells around metal/metal oxide nanoparticles which enhance their electrochemical performance in supercapacitors [38,39] and Li-ion batteries [40][41][42][43].…”

N-doped highly microporous carbons have been successfully fabricated from N-rich microalgae by the combination of low-cost hydrothermal carbonization and industryadopted KOH activation processes. The hydrothermal carbonization process was found to be an essential step for the successful conversion of microalgae into a carbon material. The materials thus synthesized showed BET surface areas in the range ~ 1800-2200 m 2 g-1 exclusively ascribed to micropores. The carbons showed N contents in the 0.7-2.7 wt.%, owing to the use of N-rich microalgae as a carbon precursor. When tested in symmetric double layer capacitors (occasionally called supercapacitors) based on aqueous LiCl electrolytes, pseudocapacitance was only observable for the sample synthesized at the lowest temperature, 650 ºC, which is the one exhibiting the largest amount of N-and O-containing groups. The samples synthesized at 700-750ºC exhibited excellent rate capability (only 20 % of capacitance loose at 20 A g-1), with specific capacitances of 170-200 F g-1 at 0.1 A g-1. These materials showed excellent long-term cycling stability under high current densities.
