“…Lithium/thionyl chloride batteries are known among the highest energy systems; 25 years ago, the output can reach 480 Wh kg −1 . 1 But now, commercially available batteries can reach 710 Wh kg −1 and have a service life of 10 to 20 years. Precisely because of its extremely high energy content, such batteries must be designed differently for each type of application; for example, one type of such a battery is designed for use in space.…”

Li/SOCl2 batteries, which are used in various fields due to theirs easy-carry and brilliant electrochemical properties, have attracted much research. However, the existence of the voltage hysteresis has limited further practical application of this tiny device. Herein, three series of nineteen kinds of metal phthalocyanine electrocatalysts with excellent electronic conductivity were synthesized to improve Li/SOCl2 battery performance. The structure of the catalysts was verified by infrared spectroscopy, ultraviolet-visible spectroscopy, thermogravimetric analysis, and elemental analysis, and these materials were used to develop the discharge time, output voltage, and discharge capacity of the Li/SOCl2 battery. With the addition of the phthalocyanine, the discharge time of the Li/SOCl2 battery lengthens by approximately 20%, and the voltage can be increased by 0.02∼0.20 V. In addition, the actual battery capacity can also be raised by 20∼50%. Density functional theory was used to calculate the relationship between the metal center and catalytic activity and the results are in good agreement with the experimental which implies the electron density of the center metal is the key point in the electrocatalyst reaction.

Despite its potential role as an atmospheric pollutant, thionyl chloride, SOCl2, remains poorly characterized in the gas phase. In this study, the pure rotational and ro-vibrational spectra of six isotopologues of this molecule, all detected in natural abundance, have been extensively studied from the cm-wave band to the far-infrared region by means of three complementary techniques: chirped-pulse Fourier transform microwave spectroscopy, sub-millimeter-wave spectroscopy using frequency multiplier chain, and synchrotron-based far-infrared spectroscopy. Owing to the complex line pattern which results from two nuclei with non-zero spins, new, high-level quantum-chemical calculations of the hyperfine structure played a crucial role in the spectroscopic analysis. From the combined experimental and theoretical work, an accurate semi-experimental equilibrium structure (r(e)(SE)) of SOCl2 has been derived. With the present data, spectroscopy-based methods can now be applied with confidence to detect and monitor this species, either by remote sensing or in situ.

Electrochemical Burn Rate Acceleration

An electrochemical mechanism of accelerating the burn rate of pyrotechnic compositions and composite propellants is presented. Magnesium-Teflon-graphite fluoride-graphite (MTGFG) compositions were used as the model system to demonstrate the effect. Electric currents are generated in situ by electrochemical cell reactions in the composition itself by introducing materials with differing electrochemical potentials and an electrolyte into the composition. Electric currents flow through the combusting surface, where materials melt and allow ion transport. The electrochemical cell is shorted at the burning surface providing more heat feedback than the back radiation from the flame alone accelerating the combustion considerably. No external power source nor auxiliary electrodes are required to increase the burn rate by electric currents like with methods hitherto known. Up to a 2.5-fold increase in the burn rate of baseline composition was achieved by using graphite as the cathode material, the magnesium powder in the composition as anode, and graphite fluoride (GF) as depolarizer and oxidizer in the cell reactions. Various electrolytes were investigated keeping the base composition otherwise unchanged.
