High-capacity thin-film germanium was coupled with free-standing single-wall carbon nanotube (SWCNT) current collectors as a novel lithium ion battery anode. A series of Ge–SWCNT compositions were fabricated and characterized by scanning electron microscopy and Raman spectroscopy. The lithium ion storage capacities of the anodes were measured to be proportional to the Ge weight loading, with a 40 wt% Ge–SWCNT electrode measuring 800 mAh/g. Full batteries comprising a Ge–SWCNT anode in concert with a LiCoO2 cathode have demonstrated a nominal voltage of 3.35 V and anode energy densities 3× the conventional graphite-based value. The higher observed energy density for Ge–SWCNT anodes has been used to calculate the relative improvement in full battery performance when capacity matched with conventional cathodes (e.g., LiCoO2, LiNiCoAlO2, and LiFePO4). The results show a >50% increase in both specific and volumetric energy densities, with values approaching 275 Wh/kg and 700 Wh/L.

Spinel structure NiCo2O4 suffers from poor electric conductivity and the resulted electrochemical properties in battery/supercapacitor system are still unsatisfied. In this paper, a free-standing electrode based on in-situ growth NiCo2O4 on carbon cloth has been synthesized by a surfactant-assisted solvothermal method (sodium dodecyl sulfate, SDS). The functional carbon cloth substrate makes unexpected contribution to the electrochemical lithium-ion storage. The assembled supercapacitor possesses ultrahigh pseudocapacitive properties with high mass loading. The specific capacitance of 2832[Formula: see text]F[Formula: see text]g[Formula: see text] has been obtained at 1[Formula: see text]A[Formula: see text]g[Formula: see text] current density with maintaining the high rate capability of 1620[Formula: see text]F[Formula: see text]g[Formula: see text] at 20[Formula: see text]A[Formula: see text]g[Formula: see text]. The obtained nanoneedle NiCo2O4/carbon cloth electrode also maintains a specific capacity of 2000[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text] at 40[Formula: see text]mA[Formula: see text]g[Formula: see text] and exceptional rate performance (1504[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 400[Formula: see text]mA[Formula: see text]g[Formula: see text] when tested as anode material in lithium ion batteries.
