“…The difficulty in using nanoparticles is that they must be supported [35], even during preparation when using template synthesis [36], which may negate the advantage of their small size unless they are effectively unconstrained. One approach to achieve this is to support the Sn particles on fibers [20,[37][38][39] or even inside fibers [40], inside carbon shells [41] or nanotubes [33] or inside carbon 'onions' [42] or as C/Sn composite [43]. An alternative is to coat the Sn on a fiber [44].…”

TEM in situ lithiation of tin nanoneedles for battery applications

Materials such as tin (Sn) and silicon that alloy with lithium (Li) have attracted renewed interest as anode materials in Li-ion batteries. Although their superior capacity to graphite and other intercalation materials has been known for decades, their mechanical instability due to extreme volume changes during cycling has traditionally limited their commercial viability. This limitation is changing as processes emerge that produce nanostructured electrodes. The nanostructures can accommodate the repeated expansion and contraction as Li is inserted and removed without failing mechanically. Recently, one such nano-manufacturing process, which is capable of depositing coatings of Sn ''nanoneedles'' at low temperature with no template and at industrial scales, has been described. The present work is concerned with observations of the lithiation and delithiation behavior of these Sn nanoneedles during in situ experiments in the transmission electron microscope, along with a brief review of how in situ TEM experiments have been used to study the lithiation of Lialloying materials. Individual needles are successfully lithiated and delithiated in solid-state half-cells against a Li-metal counter-electrode. The microstructural evolution of the needles is discussed, including the transformation of one needle from single-crystal Sn to polycrystalline Sn-Li and back to single-crystal Sn.

“…PbO-C and commercial PbO materials are compared in Fig. [46][47][48][49][50][51][52][53][54] The synthesized electrode is superior to the other carbon-based composite electrodes. The PbO/Cu-C electrode exhibits a relatively stable reversible capacity of 320 mA h g À1 in 4000 deep cycles based on the weight of the active material (not shown in gure).…”

Nanostructured composites of lead oxide/copper-carbon (PbO/Cu-C) were synthesized through in situ solvothermal synthesis and heat treatment of PbO/Cu with polyvinyl pyrrolidone (PVP) and used as lithium-ion battery anodes. A PbO active particle was embedded in the Cu and PVP-C matrix, accommodating volume changes and maintaining the electronic conductivity of PbO. The composite exhibits a superior electrochemical performance, with a capacity of 420 mA h g À1 at a current density of 165 mA g À1 , compared with previously reported Pb and PbO composite anodes. The developed anode exhibits >90% capacity retention after 9500 cycles, beginning from the second cycle, at a current density of 5.5 A g À1 .

“…. This change of I D /I G value with boron addition is helpful for the efficient electron conduction when used as the anode materials for LIBs36 . All the curves exhibit a broad peak of amorphous graphitic carbon (JCPDS 13-0148) near 25°, while no other diffraction peaks can be observed, indicating the amorphous nature of the B 2 O 3 -SnO x particles.…”

A series of carbon nanofibers-supported B2O3-SnOx glasses (0B2O3-SnOx/CNFs, 0.5B2O3-SnOx/CNFs, 1.5B2O3-SnOx/CNFs and 3B2O3-SnOx/CNFs) have been prepared by the electrospinning technique, subsequent stabilization and carbonization treatment. The amorphous B2O3-SnOx glasses nanoparticles homogeneously dispersed in carbon nanofibers (CNFs) matrix have been utilized as anode materials for lithium-ion batteries. The typical 1.5B2O3-SnOx/CNFs nano hybrid anode material demonstrates the highest reversible capacity as well as superior cycling stability and rate performance by virtue of the special glasses network structure of non-bridging oxygen (NBO: B-O … Sn) in the B2O3-SnOx glasses, which can not only buffer the large volume change of SnOx, but also prohibit the aggregation of Sn nanoparticles during the charge-discharg cycles. Graphical AbstractThe addition of Boron effectively prohibit the aggregation of Sn nanoparticles during the charge-discharg cycles
