“…Historically, TMCh were associated mainly with thermoelectric applications and are still considered to be the benchmark for other materials, displaying performance beyond the capabilities of other materials groups. 1–10 However, recently, they have gained a lot of interest with regard to the possibility of their utilization in a number of other technologies operating on the basis of electrocatalytic processes, including photochemistry, 11–13 sensors, 12,14,15 fuel cells, and catalysis. 12,16,17 This interest stems from their excellent catalytic activity with respect to some of the most fundamental catalytic reactions, namely hydrogen evolution reaction (HER), and the oxygen evolution reaction (OER).…”

“…Among different structure copper sulfides (CuS, Cu 9 S 8 , etc . ), Cu 2 S has better thermal stability. , Recently, a series of copper sulfides have been developed as electrodes for LIBs and NIBs with impressive performance. ,, However, there are few reports about copper sulfides as anodes for KIBs because of the unsatisfactory electrochemical performance caused by the slower diffusion kinetics of K + and greater volume change during cycling, which bring greater challenges to the structural design of electrode materials.…”

Transition metal sulfides (TMSs) have been demonstrated as attractive anodes for potassium-ion batteries (KIBs) due to the high capacity, abundant resource, and excellent redox reversibility. Unfortunately, practical implementation of TMSs to KIBs is still hindered by the unsatisfactory cyclability and rate performance which result from the vast volume variation during charge/discharge processes. Herein, a uniform nitrogen-doped carbon coated Cu2S hollow nanocube (Cu2S@NC) is designed as an anode material for the KIB, which displays an outstanding cycle performance (317 mAh g–1 after 1200 cycles at 1 A g–1) and excellent rate capacity (257 mAh g–1 at 6 A g–1) in a half-cell. The hollow nanosized structure can both shorten the diffusion length of potassium ions/electrons and buffer the volume expansion upon cycling. Besides, the high concentration electrolyte is beneficial to form the stable solid electrolyte interphase (SEI) film, reducing the interface impedance and enhancing the cycling stability. Ex situ transmission electron microscopy (TEM) and ex situ X-ray diffraction (XRD) reveal the reaction mechanism of Cu2S@NC.

“…Suekuni et al, 2013). These and other studies were guided by modern computational simulations that investigated the electronic properties of doped tetrahedrites (Lara-Curzio et al, 2014;Tablero, 2014;Zhou et al, 2014;Kim et al, 2019a;Pi et al, 2019). As discussed previously, E F lies at the valence band edge for the Cu-based composition, and adding Zn atoms, which strictly adopt a divalent state, effectively raises E F into the gap.…”

“…Thus, impurity substitution leads to a stabilization of the compound and raise its maximum operating temperature. Lastly, Pi et al studied the mechanical properties of tetrahedrites after thermal aging in air and vacuum (Pi et al, 2019). They reported values for the Vickers hardness and bending strength of copper-based tetrahedrites.…”

Thermoelectric materials have a long and storied history in the research and development of semiconductor materials, being the first such class of materials to be investigated. Thermoelectrics may be used to convert heat to electricity or, alternatively, to liberate or absorb heat upon electrical excitation. They thus find application in thermoelectric generators for converting heat from a primary source or a waste stream to useful electrical power, and as solid state heating and cooling devices. In spite of their great potential in such important applications, thermoelectrics have suffered from a number of drawbacks that have hindered their utilization on a large scale. Chief among these is the fact that most high performance thermoelectric materials are comprised of elements that are in relatively low abundance. Additionally, their synthesis typically involves complex and multi-step processes, hindering manufacturability. Thermoelectric materials derived from Earth-abundant sources are thus of strong current interest, from both scientific and economic points of view. One of these, the family of semiconductors based on tetrahedrite compounds, has generated enormous interest over the last decade due to not only its potential low cost, but also for its fascinating science. In this review, we summarize the state of the art of tetrahedrite as a thermoelectric, with special emphasis on the relationship between crystal structure and bonding in the crystal and its unusually low lattice thermal conductivity; on its fascinating electronic structure; and on the wide array of compositions that have been synthesized and whose thermoelectric properties have been studied. We further highlight some rapid and facile synthesis techniques that have been developed for these compounds which, in combination with their potential low material cost, may open the door to widespread application of these fascinating materials.
