Shilin Mei,Charl J. Jafta,Iver Lauermann,Qidi Ran,Martin Kärgell,Matthias Ballauff,Matthias Ballauff,Yan Lu,Yan Lu +8 more
TL;DR: In this article, multifunctional Ti4O7 particles with interconnected-pore structure are designed and synthesized using porous poly(styrene-b-2-vinylpyridine) particles as a template.
Journal ArticleDOI
Microwave-Assisted Synthesis of High-Voltage Nanostructured LiMn1.5Ni0.5O4 Spinel: Tuning the Mn3+ Content and Electrochemical Performance
Charl J. Jafta,Charl J. Jafta,Mkhulu Mathe,Ncholu I. Manyala,W. D. Roos,Kenneth I. Ozoemena,Kenneth I. Ozoemena +6 more
TL;DR: It is shown that microwave is capable of tuning the Mn(3+) content of the spinel for enhanced electrochemical performance (high capacity, high capacity retention, excellent rate capability, and fast Li(+) insertion/extraction kinetics).
Journal ArticleDOI
