The capacity rising is due to the biphasic coexistence of MoS2 during the cycling and the progressive increase in the 1T-MoS2 content. Simultaneously, the layer spacing expanded from 0.62 nm to 1.03 nm during the cycling process.

Orthorhombic Na0.44MnO2 with an S-shape tunnel structure was successfully synthesized by a hydrothermal method. The Na0.44MnO2 material has lattice parameters of a = 9.0842 Å, b = 26.2889 Å, and c = 2.8245 Å. Scanning electron microscope analysis reveals that the morphologies of Na0.44MnO2 consist of Na0.44MnO2 nanowires with diameters of about 30-50 nm and Na0.44MnO2 particles with the size in the range of 200 to 500 nm. The first charge and discharge capacities of Na0.44MnO2 cathode, at 0.1 C between 2.0-4.0 V, are 66.2 mAh g-1 and 62.7 mAh g-1, respectively. The Na0.44MnO2 has an excellent cycle stability with 85.3% of capacity retention over 50 cycles. The coulombic efficiency of Na0.44MnO2 material is approximately 90% after 70 cycles. It is suggested that the structure of Na0.44MnO2 is stable during cycling and Na0.44MnO2 can be a promising cathode material for sodium ion batteries.

The maximally disordered (MD) phases with the general formula Y5−xPrxSb3−yMy (M = Sn, Pb) are formed with partial substitution of Y by Pr and Sb by Sn or Pb in the binary Y5Sb3 compound. During the electrochemical lithiation and sodiation, the formation of Y5-xPrxSb3-yMyLiz and Y5−xPrxSb3−yMyNaz maximally disordered–high entropy intermetallic phases (MD-HEIP), as the result of insertion of Li/Na into octahedral voids, were observed. Carbon nanotubes (CNT) are an effective additive to improve the cycle stability of the Y5−xPrxSb3−yMy (M = Sn, Pb) anodes for lithium-ion (LIBs) and sodium-ion batteries (SIBs). Modification of Y5−xPrxSb3−ySny alloys by carbon nanotubes allowed us to significantly increase the discharge capacity of both types of batteries, which reaches 280 mAh · g−1 (for LIBs) and 160 mAh · g−1 (for SIBs), respectively. For Y5−xPrxSb3−yPby alloys in which antimony is replaced by lead, these capacities are slightly smaller and are 270 mAh · g−1 (for LIBs) and 155 mAh · g−1 (for SIBs), respectively. Results show that structure disordering and CNT additives could increase the electrode capacities up to 30% for LIBs and up to 25% for SIBs.
