High energy density rechargeable magnesium battery using earth-abundant and non-toxic elements
Rechargeable magnesium batteries are poised to be viable candidates for large-scale energy storage devices in smart grid communities and electric vehicles. However, the energy density of previously proposed rechargeable magnesium batteries is low, limited mainly by the cathode materials. Here, we present new design approaches for the cathode in order to realize a high-energy-density rechargeabl...
متن کاملHybrid system for rechargeable magnesium battery with high energy density
One of the main challenges of electrical energy storage (EES) is the development of environmentally friendly battery systems with high safety and high energy density. Rechargeable Mg batteries have been long considered as one highly promising system due to the use of low cost and dendrite-free magnesium metal. The bottleneck for traditional Mg batteries is to achieve high energy density since t...
متن کاملHigh power rechargeable magnesium/iodine battery chemistry
Rechargeable magnesium batteries have attracted considerable attention because of their potential high energy density and low cost. However, their development has been severely hindered because of the lack of appropriate cathode materials. Here we report a rechargeable magnesium/iodine battery, in which the soluble iodine reacts with Mg2+ to form a soluble intermediate and then an insoluble fin...
متن کاملManganese Dioxide As Rechargeable Magnesium Battery Cathode
Rechargeable magnesium battery (rMB) has received increased attention as a promising alternative to current Li-ion technology. However, the lack of appropriate cathode that provides high-energy density and good sustainability greatly hinders the development of practical rMBs. To date, the successful Mg2+-intercalation was only achieved in only a few cathode hosts, one of which is manganese diox...
متن کاملAn aqueous rechargeable lithium battery of high energy density based on coated Li metal and LiCoO2.
Using a coated Li metal as an anode and LiCoO2 as a cathode, an aqueous rechargeable battery is built up, whose average discharge voltage is 3.70 V. This high voltage stability is due to the "cross-over" effect of Li(+) ions, which is different from the traditional ways of increasing overpotentials. The total energy density can be 465 W h kg(-1).
