Abstract

The high price of Co and Ni restricts the development of the lithium-ion battery industry. Reducing the Ni content and eliminating Co is an effective way to lower the cost. In this work, we eliminate the Co in NCM523 cathodes by using a complex concentrated doping strategy. LiNi0.5Mn0.4Ti0.03Mg0.03Nb0.01Mo0.03O2 shows an unparalleled cost advantage with relatively high specific energy (>720 W h kg−1) and significantly improved overall performance (96% capacity retained after 1000 cycles). This report offers an important pathway to fabricate cathode materials for low-cost and long-life LIBs. [ABSTRACT FROM AUTHOR]

Abstract

Cubic Cu mesocrystals were prepared viaa facile solvothermal reaction in a mixed solvent of glycerol–water. The microstructure of synthesized mesocrystals can be successfully controlled by adjusting the volume ratio of glycerol/water. The evolution of these cubic Cu mesocrystals was investigated and the mechanism was discussed. The oriented attachment process controls the initial stage in the formation of scabbled cubic Cu mesocrystals and then Ostwald ripening process contributes to the formation of the final Cu mesocrystals by shearing the scabbled mesocrystals. The influences of reaction temperature and NaOH concentration on the morphology of the synthesized mesocrystals were also investigated. Isotropic conductive adhesives (ICA), filled with cubic Cu mesocrystals, exhibit a low bulk resistivity, of about 5.21 × 10−4Ω cm. [ABSTRACT FROM AUTHOR]
