The Rechargeable Aluminum Battery: Opportunities and Challenges

“…In addition, defects in the Al 2 O 3 film can provide channels for electrolyte infiltration and realize electrostripping/deposition. In another study, an on-corrosive and moisture stable [BMIm]OTF-Al(OTF) 3 electrolyte was used instead of the corrosive [EMIm]Cl-AlCl 3 electrolyte,and no electrostripping/ deposition activity could be observed, [126] while such activity did occur when the aluminum anode was pretreated in ac orrosive [BMIm]Cl-AlCl 3 electrolyte.Infact, the oxide film that naturally formed on the aluminum surface is so compact that the RTIL electrolyte cannot permeate it. However,c orrosive Al 2 Cl 7 À can etch and cause fissures in this film leading to aconnection between electrolyte and aluminum so that electrostripping/ deposition activity is achieved ( Figure 12).…”

“…It is beyond all doubt that lithium batteries are one of the better energy-storage systems if only because of the attractive physical and chemical properties of the lithium anode,such as the lowest redox voltage (À3.045 Vv s. the normal hydrogen electrode (NHE)) and highest gravimetric capacity (3857 mAh g À1 )ofthe pure lithium metal anode as compared to other metal anodes. [1][2][3][4] However,considering both mobile (electronic devices and EVs) and large-scale stationary energy storage systems,i ti su ncertain whether lithium resources (0.0065 wt %o ft he earthsc rust as shown in Figure 1) are enough to satisfy the demand. In addition, the flammable,p oisonous,a nd volatile electrolytes used are not compatible with the development of environmentally friendly chemistry.…”

A Review of Advanced Energy Materials for Magnesium–Sulfur Batteries

“…Furthermore, metallic magnesium can be safely processed under air and does not form dendrites, thus fulfilling important aspects of easy fabrication and safety operation in battery devices . On the other hand, the intrinsic lithium dendrite growth continuously consumes electrolytes and has the potential of causing catastrophic explosion, which presents pressing challenges for the lithium metal batteries …”

P4S10 modified lithium anode for enhanced performance of lithium–sulfur batteries

“…However, during cycling, the corrosion reaction occurs and the formation of Li dendrites is found on the surface of lithium metal, leading to safety hazards, bad cycling stability and low Coulombic efficiency, crippling the commercialization of lithium-sulfur batteries [7,8] . Firstly, lithium dendrites, induced by the non-uniform deposition of Li, may pierce the polymer separator, causing the internal cell short circuit and serious safety concerns [9,10] . The dendritic Li could also lead to an electrical detachment of Li from the current collector and become "dead Li", significantly shortening the cycle life of the Li metal battery [11,12] .…”
