Boron-doping-induced defect engineering enables high performance of a graphene cathode for aluminum batteries

Abstract

Rechargeable aluminum batteries (RABs) have received significant interest due to the low cost, high volumetric capacity, and low flammability of aluminum. However, the paucity of reliable cathode materials poses substantial...

Investigation of Si-Coated Multiwalled Carbon Nanotubes as Potential Electrodes for Multivalent Metal-Ion Electrochemical Energy Storage Systems

“…The high flammability of lithium-containing organic electrolytes causes frequent fire and explosive incidents in LIBs, which prompts the demand for alternative battery systems. 10,11 Multivalent ion batteries (MIBs) have emerged as potential candidates due to their low cost, safety, energy density, and widespread resource availability. 12−14 When multivalent ions are integrated into an appropriate anode, they can transmit multiple electrons, resulting in a high theoretical capacity and energy density.…”

Twin boundary CdxZn1−xS: a new anode for high reversibility and stability lithium/sodium-ion batteries

“…6,7 For example, the synthesized electrode materials of nitrogen-rich sulfur-doped porous carbon materials, boron doped reduced graphene oxide, oxygen vacancy modied MoO 2 /reduced graphene oxide nanotubes, and MoS 2 nanoakes decorated with sulfur vacancies show improved electrochemical performance. [8][9][10][11] Line defects, which originate from the dislocation of the atomic plane in the crystal lattice, are mainly manifested in the form of screw dislocation and edge dislocation. Such defects are benecial for providing sufficient active centers and promoting ion diffusion and charge transfer, which plays an important role in improving the energy storage performance of electrode materials.…”

Constructing NiCo2Se4/NiCoS4 heterostructures for high-performance rechargeable aluminum battery cathodes

“…6 Among these post-LIBs, rechargeable aluminum batteries (RABs) have been regarded as a replacement for LIBs because aluminum (Al) is the most abundant metal in the Earth's crust (82 000 ppm for Al), and it has ultrahigh theoretical volumetric capacities (8035 mA h cm −3 ) and theoretical gravimetric capacities (2980 mA h g −1 ). 7 Inspired by Dai's research that designed RABs comprising graphitic-foam cathodes, Al anodes, and [EMIm]Al x Cl y ionic liquid electrolytes, 8 more and more research on cathode materials for aluminum batteries has been carried out, mainly concentrating on carbon-based materials, [9][10][11][12][13][14][15] organic molecules, [16][17][18][19] oxides, [20][21][22] sulfides, [23][24][25] selenides, [26][27][28][29][30] and tellurides. 31 Nonetheless, the development of cathode materials has encountered some challenging issues.…”
