Batteries are becoming increasingly important in today's world of portable electronic devices, along with the need to store electricity derived from solar and other renewable forms of energy, and the desire to introduce electric and hybrid electric vehicles to reduce emissions. Understanding Batteries ...
Apart from the above methods, oxygen anion substitution can also significantly improve the interfacial stability between the SSE and the anode. Oxygen anion substitution not only broadens the electrochemical window of the SSE [52], but also inhibits the interfacial reaction to a certain extent through...
Exploring Oxygen Activity in the High Energy P2-Type Na0.78Ni0.23Mn0.69O2 Cathode Material for Na-Ion Batteries Large-scale electric energy storage is fundamental to the use of renewable energy. Recently, research and development efforts on room-temperature sodium-ion batteries (NIBs) have been rev...
Electrolytes highly enriched with oxygen for lithium–oxygen (Li–O2) batteries were prepared by combining perfluorohexyl bromide as an oxygen-uptake perfluorochemical (PFC) medium with lithium perfluorooctane sulfonate (LiPFOS) as a perfluoro-surfactant and a supporting electrolyte, which allowed an exc...
Li-ion batteries have transformed portable electronics and will play a key role in the electrification of transport. However, the highest energy storage possible for Li-ion batteries is insufficient for the long-term needs of society, for example, extended-range electric vehicles. To go beyond the...
but these conceal a chemistry with significant potential that is held back by the difficulty of creating a reliable cathode. In these batteries the cathode is a porous support in which a reaction between zinc powder wet paste and oxygen in the air occurs, turning zinc into zinc oxide and rele...

Battery fires are difficult to extinguish because oxygen is formed by an internal chemical reaction at the cathode, so oxygen from the atmosphere is not required for a fire (Chapter 12C: Ignition and Extinction of Battery Fires). The reaction of the cell materials generates not only oxygen but...
(RSL) growth become increasingly problematic for maintaining practical cell lifetimes, RSL formation generally leading to impedance rise2,3. RSL formation and the concomitant loss of oxygen have been proposed to be the primary driver of electrolyte oxidation at high voltages, rather than Faradaic ...
and the residual oxygen functional groups on rGO provided anchoring sites to trap the soluble polysulfide intermediates within the electrode. Very impressively, the GF-rGO/S cathodes with a sulfur loading of 9.8mgcm−2and sulfur content of 83wt% showed a high areal capacity of 10.3mAhcm−...
