“…[ 30 ] At present, M x Mo 6 T 8 phases have been utilized as host materials for multivalent metal ions intercalation due to the chemical intercalation properties of various guest elements like Ca, Mg, Ba, Cr, Mn, Fe, Co, Ni, etc. [ 19b,31 ] In 1980, Umarji et al. [ 31a ] first discovered the remarkable change in the unit‐cell parameters before and after cathodic reduction, which evidenced the Zn intercalation reaction of Mo 3 S 4 phase.…”

“…Later, Gocke et al. [ 31b ] detected two potential plateau regions by galvanostatic cathodic reduction of Mo 6 S 8 in 2 m Zn(ClO 4 ) 2 /CH 3 CN electrolyte, one (≈0.47 V) for 0 ≤ x ≤ 1 and the other (≈0.3 V) for 1 ≤ x ≤ 2 in Zn x Mo 6 S 8 , respectively. The anodic oxidation reaction of Zn 2 Mo 6 S 8 revealed reversible transformation and high structural stability at low operating voltage from Zn 2 Mo 6 S 8 to Mo 6 S 8 , respectively.…”

In the past decades, the world has witnessed the successful commercialization of “rocking‐chair”‐type lithium‐ion batteries with lithium metal free anodes. Owing to their safe, green, easy manufacturing, and cost‐efficiency characteristics, rechargeable zinc batteries have recently received more and more attention. However, the practical application of Zn metal batteries is hampered mainly by the dendritic growth of Zn metal anode, which leads to poor Coulombic efficiency, hazards, and various side reactions. Herein, the emerging “rocking‐chair”‐type Zn‐ion batteries are systemically reviewed with Zn host anodes instead of Zn metal anodes. As an introduction, the fundamental principles, advantages, and challenges of “rocking‐chair”‐type Zn‐ion batteries are discussed. Subsequently, the design principles and recent advances of cathode, anode, and electrolyte for “rocking‐chair” Zn‐ion batteries are summarized. To conclude, perspectives on the future of “rocking‐chair” Zn‐ion batteries are presented. It is hoped that this review may provide alternative directions for the design of Zn‐ion batteries.

“…Finally, the electrical resistivity can be tuned, by varying the VEC. Although first evaluations of Seebeck coefficients of metallic CPs were published quite early [100,101], it is only in the late 90's that theoretical calculations were carried out for the search of CP-based thermoelectric materials [102,103].

This chapter summarizes the important role played by Marcel Sergent in the discovery in the Rennes Laboratory of the Chevrel-Phases, which stimulated considerable interest in the international solid state chemistry community, because of their remarkable superconducting properties. After a brief general introduction to this topic the seminal discoveries associated with these phases between 1970 and 1990 are described. After their initial synthesis and structural determination was discovered, it was necessary to establish their critical superconducting transition temperature, the critical magnetic field and the critical current density in wires, single crystals, and thin films. More recently their applications as battery materials, in catalysis and their thermo-electric properties have been studied and are briefly described. These phases opened up the way not only to a rich solid state chemistry, but also to a rich solution chemistry, which complemented the classical field of transition metal carbonyl clusters. The basic cluster units of the Chevrel-Phases continue to be studied in the Rennes laboratory by the heirs of Marcel Sergent and more widely in the international community.

“…Li, Cu, Co, Ni), can be leached out by a simple mineral acid treatment or electrochemical oxidation to give rise to the binary Mo6Ch 8 compounds. Of course, the reverse process of insertion of foreign metal atoms into the channels of Mo6Cha to give ternaries is also possible and has been studied (Fischer 1978;Sch611horn 1980;Umarji et al 1980).…”

A survey of the known high Tc ternary systems of compounds is presented. Special emphasis has been placed on the part played by the crystal structure and bonding in the exhibition of high T~ superconductivity. The superconducting and other physical properties of the ternary borides have been discussed in relatively more detail. Finally, the available guidelines from crystal and solid state chemistry points of view, have been reiterated for a search for new high T, materials.
