ABSTRACTSilicon is emerging as a very attractive anode material for lithium ion batteries due to its low discharge potential, natural abundance, and high theoretical capacity of 4200 mAh/g, more than ten times that of graphite (372 mAh/g). This high charge capacity is the result of silicon’s ability to incorporate 4.4 lithium atoms per silicon atom; however, the incorporation of lithium also leads to a 300-400% volume expansion during charging, which can cause pulverization of the material and loss of access to the silicon. The architecture of the anode must therefore be able to adapt to this volume increase. Here we present a layered carbon nanotube and silicon nanoparticle electrode structure, fabricated using directed assembly techniques. The porous carbon nanotube layers maintain electrical connectivity through the active material and increase the surface area of the current collector. Using this architecture, we obtain an initial capacity in excess of 4000 mAh/g, as well as increased power and energy density as compared to anodes fabricated using the standard procedure of slurry casting.

Carbon nanotube fiber (CNTF) is a highly conductive and porous platform to grow active materials of lithium-ion batteries (LIB). Here, we prepared SnO2@CNTF based on sulfonic acid-functionalized CNTF to be used in LIB anodes without binder, conductive agent, and current collector. The SnO2 nanoparticles were grown on the CNTF in an aqueous system without a hydrothermal method. The functionalized CNTF exhibited higher conductivity and effective water infiltration compared to the raw CNTF. Due to the enhanced water infiltration, the functionalized CNTF became SnO2@CNTF with an ideal core–shell structure coated with a thin SnO2 layer. The specific capacity and rate capability of SnO2@-functionalized CNTF were superior to those of SnO2@raw CNTF. Since the SnO2@CNTF-based anode was free of a binder, conductive agent, and current collector, the specific capacity of the anode studied in this work was higher than that of conventional anodes.

Ti3C2Tx, a new type of two-dimensional material, is a prospective anode material in lithium-ion batteries (LIBs) for its low lithium-ion diffusion barrier, high conductivity and many other excellent properties. In this paper, multilayer Ti3C2Tx and delaminated Ti3C2Tx samples are prepared by etching Ti3AlC2 powder with HF and [Formula: see text], respectively. We explore the application of the two samples in LIBs, and analyze their electrochemical behavior and kinetic mechanism. At the current densities of 0.1[Formula: see text]A[Formula: see text]g[Formula: see text], the delaminated Ti3C2Tx electrode delivered higher capacities of 255[Formula: see text]mAh[Formula: see text]g[Formula: see text] than multilayer Ti3C2Tx electrode (100[Formula: see text]mAh[Formula: see text]g[Formula: see text]). Even after 1000 cycles, the specific capacity of the delaminated Ti3C2Tx is still up to 205[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 1[Formula: see text]A[Formula: see text]g[Formula: see text]. This work proves the great potential of the delaminated Ti3C2Tx for lithium-ion storage.
