“…2 and summarized in Table 1, electrodes containing CMC or CMC/SBR show a slightly reduced irreversible capacity loss (ICL) in the first cycle compared to those containing PVDF or PVDF-HFP as binder. Similar results for anatase TiO 2 based electrodes have been reported already by Mancini et al [25], and are in line with previous results for carbon and silicon based anodes comprising CMC [22,23]. The nature of the irreversible capacity during the first cycle has been studied by El Ouatani et al [28] for CMC and CMC/SBR graphite electrodes.…”

“…CMC, or a combination of CMC and styrene butadiene rubber (SBR), has been successfully used already for graphite and silicon based anodes [16,17,21e24]. Recently, Mancini et al [25] have investigated the use of CMC as binder for anatase TiO 2 . The electrodes showed an enhanced compactness relatively to PVDF based electrodes and an improved electrochemical performance.…”

“…Nowadays, lithium-ion batteries (LIBs) have been generally accepted as power sources for consumer electronics and electric/hybrid electric-vehicles because of their merits in terms of high energy density, long cycle life, tiny memory effect, low toxicity, and cost [1][2][3]. The battery performance is depending on the intrinsic characteristics of electrode material, and commercial carbonaceous anodes show an increased resistance at high rate, which is inappropriate for advanced high-power LIBs in future [4].…”

A simple and highly efficient method is developed for in situ one-step preparation of carbon co-encapsulated anatase and rutile TiO 2 nanocrystals (TiO 2 @C) with core-shell structure for lithium-ion battery anode. The synthesis is depending on the solid-phase reaction of titanocene dichloride with ammonium persulfate in an autoclave at 200°C for 30 min. The other three titanocene complexes including bis(cyclopentadienyl)dicarbonyl titanium, cyclopentadienyltitanium trichloride, and cyclopentadienyl(cycloheptatrienyl)titanium are used instead to comprehensively investigate the formation mechanism and to improve the microstructure of the product. The huge heat generated during the explosive reaction cleaves the cyclopentadiene ligands into small carbon fragments, which form carbon shell after oxidative dehydrogenation coating on the TiO 2 nanocrystals, resulting in the formation of core-shell structure. The TiO 2 nanocrystals prepared by titanocene dichloride have an equiaxed morphology with a small diameter of 10-55 nm and the median size is 30.3 nm. Hundreds of TiO 2 nanocrystals are encapsulated together by the worm-like carbon shell, which is amorphous and about 20-30 nm in thickness. The content of TiO 2 nanocrystals in the nanocomposite is about 31.1 wt.%. This TiO 2 @C anode shows stable cyclability and retains a good reversible capacity of 400 mAh g −1 after 100 cycles at a current density of about 100 mA g −1, owing to the enhanced conductivity and protection of carbon shell.

“…Lithium-ion batteries (LIBs) have been universally accepted as power sources for different kinds of consumer electronics as well as electric/hybrid electric vehicles in terms of their high energy density, long cycle life, tiny memory effect, low toxicity, and cost Sasaki et al 2013;Mancini et al 2011). The performance of LIBs mainly depends on the intrinsic characteristics of electrode material, and the commercial graphite anode suffers from a low theoretical specific capacity of 372 mAh g −1 according to its fully lithiated stoichiometry in the past decades, a lot of efforts have been made worldwide for exploring various candidates with different nanostructure and physicochemical property to improve the battery performance.…”

A simple and highly efficient method is developed for the one-step in situ preparation of carbonencapsulated MoO 2 nanocrystals (MoO 2 @C) with coreshell structure for high-performance lithium-ion battery anode. The synthesis is depending on the solid-state reaction of cyclopentadienylmolybdenum tricarbonyl dimer with ammonium persulfate in an autoclave at 200°C for 30 min. The large amount of heat generated during the explosive reaction cleaves the cyclopentadiene ligands into small carbon fragments, which form carbon shell after oxidative dehydrogenation coating on the MoO 2 nanocrystals, resulting in the formation of core-shell structure. The MoO 2 nanocrystals have an equiaxial morphology with an ultrafine diameter of 2-8 nm, and the median size is 4.9 nm. Hundreds of MoO 2 nanocrystals are encapsulated together by the worm-like carbon shell, which is amorphous and about 3-5 nm in thickness. The content of MoO 2 nanocrystals in the nanocomposite is about 69.3 wt.%. The MoO 2 @C anode shows stable cyclability and retains a high reversible capacity of 443 mAh g −1 after 50 cycles at a current density of 3 A g −1, owing to the effective protection of carbon shell.
