The high rate capability and structural stability of the olivine phosphates attracted a lot of interest as promising cathode materials for high energy density batteries. Alteration on these cathode materials, for instance, reducing particle size, conductive coating and metal ion doping were performed in order to improve the conductivity and to obtain high specific Li + diffusion. However, the drastic improvement in electrical conductivity for the aliovalent doping is still unclear. Rather writing a lengthy standard review, this manuscript intends to describe briefly the lattice defects owing to metal ion doping and its influence in improving the cathode performance of the olivine phosphates. This gives a new approach in this field.

“…1 Zinc negative electrode is promising candidates for an aqueous alkaline metal negative material with favorable properties such as high energy density, high safety, low toxicity and low cost. 2 In addition, it can be used under wider potential window than that of water electrolysis (1.23 V). 3 Some problems, however, have prevented the practical use of the zinc metal negative electrode.…”

Suppression of Dendrite Formation by Using a Hydrogel Separator for Zinc Alkaline Battery

et al. 2017

A self-standing polyacrylate based hydrogel sheet was examined as a separator of an alkaline zinc secondary battery. It suppressed the zinc dendrite formation and resultant internal short circuit. The morphology of electrodeposited zinc under a hydrogel sheet was plate-like which was different from that of electrodeposited under a conventional nonwoven fabric separator. The nickel-zinc battery using the hydrogel sheet as a separator achieved more than 50 charge-discharge cycles.

“…1,2 However, the insufficient cycle time of these zinc-based secondary batteries has limited their wide implementation. It has been reported that the rechargeability of the zinc electrode is governed by its morphology, which is largely affected by the reduction (deposition) condition on charging and the oxidation (dissolution) condition on discharging.…”

<i>Operando</i> X-ray Fluorescence Imaging for Zinc-based Secondary Batteries

et al. 2015

View full text Add to dashboard Cite

Zinc-based secondary aqueous batteries are promising candidates as innovative batteries for their high energy density and high safety. Their limited cycle life is chiefly due to the morphology changes of the zinc electrode and thus tracking the zinc distribution during electrochemical processes is indispensable for clarifying the deterioration mechanism of the zinc electrode. We here report the zinc distribution near the electrode in a millimeter scale on zinc reduction and oxidation observed by operando X-ray fluorescence imaging with a high time resolution. The zinc dendritic growth and its dissolution behavior is discussed based on the obtained zinc distribution images.
