Sodium iron phospho-olivine, NaFePO4, is a promising cathode material for Na-ion batteries. However, extraction and intercalation induce large discontinuous volume change (>10 vol %), which leads to transformation strains may hamper the rate capability as well cyclic stability of NaFePO4. In Li-ion counterpart LiFePO4, size can be effectively reduced by substitution Mn onto Fe sites in phospho-olivine structure, i.e., LiMnyFe1–yPO4 solid solution. this paper, we investigate battery...
The electron-donor and unique redox properties of the tetrathiafulvalene (TTF, 1 ) moiety have led to diverse applications in many areas chemistry. Monopyrrolotetrathiafulvalenes (MPTTFs, 4 bispyrrolotetrathiafulvalenes (BPTTFs, 5 are useful structural motifs found widespread use fields such as supramolecular chemistry molecular electronics. Protocols enabling synthesis functionalised MPTTFs BPTTFs therefore broad interest. Herein, we present a range MPTTF BPTTF species. Firstly, large-scale...
The synthesis and thermal degradation of MAl4(OH)12SO4·3H2O layered double hydroxides with M = Co2+, Ni2+, Cu2+, Zn2+ ("MAl4-LDH") were investigated by inductively coupled plasma-optical emission spectroscopy, thermogravimetric analysis, powder X-ray diffraction, Rietveld refinement, scanning electron microscopy, tunnel energy-dispersive solid-state 1H 27Al NMR spectroscopy. Following extensive optimization, phase pure CoAl4- NiAl4-LDH obtained, whereas 10-12% unreacted bayerite (Al(OH)3)...
Recycling of Li-ion batteries is going to be a major challenge in the coming years order preserve precious resources battery materials. Within this lies task identifying state materials used determine recyclability material. In paper, we investigate set LiFePO4 electrodes from A123 18650 graphite-LiFePO4 cells, which have been cycled continuously for 6.5 (6533 cycles at current rate C/5). The spatially resolved morphological, chemical, and structural states as well uncycled are mapped by...
Many ion storage compounds used for electrodes in Li-ion batteries undergo a first order phase transformation between the Li-rich and Li-poor end-members during battery charge discharge. This often entails large strains due to lattice misfits, which may hamper discharge kinetics. Iron(III) hydroxide phosphate, Fe2–y(PO4)(OH)3–3y(H2O)3y−2 is promising new cathode material with high capacity, low production costs toxicity. Previous reports on this indicate that intercalation extraction...
Iron(<sc>iii</sc>) hydroxide phosphate hydrate Fe<sub>1.13</sub>(PO<sub>4</sub>)(OH)<sub>0.39</sub>(H<sub>2</sub>O)<sub>0.61</sub> is investigated for the first time as a Na-ion battery cathode. The material exhibits similar storage capacities Na- and Li-ions at relatively low current rates (<italic>i.e.</italic> C/10).
