Ion exchange offers a new way to prepare high-performance cathode materials from the perspective of materials synthesis. In this review, the mechanisms of ion exchange are presented and its application to the synthesis of layered cathode materials for lithium-ion batteries are discussed. The outlook for ion-exchange synthesis of layered cathode materials...

Recent and representative works on the application of prelithiation technologies in LIBs are well summarized and analyzed, as well as the potential directions for developing better prelithiation technologies and the possible extension of prelithiation technologies into the analogous fields of presodiation, prepotassiation, and emerging lithium-free...

A plasma-driven chemical looping ammonia synthesis process has been demonstrated by using NaH–NaNH2 as a mediator, which does not convert N2 to NH3 under thermal conditions. This hybrid chemical looping process is composed of two steps, i.e., plasma nitrogen fixation by NaH, and subsequent hydrogenation to ammonia even under ambient temperature. ...

In a systematic study toward solid polymer electrolytes in lithium-metal anode cells, voltage noise in addressed by means of lithium surface pretreatment. The limiting factor of polarization is addressed by electrolyte conductivity tuning. The examination of the role of electrolyte infiltration into the cathode on cell performance leads to a practical...

A strategy for highly efficient and robust perovskite solar cells via a greenable slot-die process is reported. Locally supersaturated perovskite ink based on low-toxic dimethyl sulfoxide is prepared by rheological engineering with a small amount of 1,2-dichlorobenzene . The findings present a strategy for designing perovskite inks and a pathway toward...

A general “engraving in aprotic medium” strategy is put forward to realize Zn foil pretreatment in terms of anode stability. The thus-produced 3D porous Zn surface is able to mitigate side reaction and dendritic formation, ensuring the excellent electrochemical performance and allowing the practical pursuit of a Zn anode. Abstract Zn foil...
