Communication—Preparation of Cu-Al Hydrotalcite-Like Materials for Supercapacitors

Abstract

[Cu-Al-[Cu(C6H4O7)]2− hydrotalcite-like compound was firstly investigated as a potential electrode for the supercapacitors. [Cu-Al-[Cu(C6H4O7)]2− was achieved by hydrothermal method and Cu-Al-CuO-C was obtained after calcination. The electrochemical performances were characterized by an electrochemical analyzer system. The specific initial capacitance of the Cu-Al-CuO-C electrode is up to 88.44 F/g, and 69.54 F/g is retained after 1000 cycles of galvanostatic charge and discharge at 5 mA/cm2. It demonstrates Cu-Al-CuO-C hydrotalcite-like compound is a good candidate as electrode for supercapacitors. This work also offers a novel perspective to exploit the potential application of hydrotalcite-like family.

Detection of Potential Transit Signals in 17 Quarters of Kepler Data: Results of the Final Kepler Mission Transiting Planet Search (Dr25)

“…The DV module and overall TCE validation approach are discussed in Wu et al (2010) and Twicken et al (2015Twicken et al ( , 2016. The DV transiting planet model fitting algorithm and multiple planet search are described in Tenenbaum et al (2010) and Li et al (2015Li et al ( , 2016.…”

“…There were substantial upgrades to DV functionality in the final revision of the pipeline code base (SOC 9.3). We list them here but defer the details to Twicken et al (2016) and Li et al (2016): 1. Trapezoidal model fitting to provide fast, robust model fits 2.…”

“…In recent DV revisions, we have attempted to uniformly distribute the initialization seed for the fitted impact parameter to some degree. The method for seeding the iterative, limb-darkened transiting planet model fits was modified in the SOC 9.3 code base as described by Li et al (2016). An inadvertent side effect of the change in model fit seeding is that all fits were initialized with a high impact parameter (0.9).…”
