Two-Dimensional Materials to Address the Lithium Battery Challenges

Abstract: Despite the ever-growing demand in safe and high power/energy density of Li+ ion and Li metal rechargeable batteries (LIBs), materials-related challenges are responsible for the majority of performance degradation in such batteries. These challenges include electrochemically induced phase transformations, repeated volume expansion and stress concentrations at interfaces, poor electrical and mechanical properties, low ionic conductivity, dendritic growth of Li, oxygen release and transition metal dissolution of… Show more

“…Transition metal oxides and TMDs are representative materials that operate through this mechanism. [ 78 ] It is worth mentioning that there are reports about 2D materials such as InSe nanoflakes that exhibit both conversion and alloying mechanisms of charge storage. [ 79 ] As expected, layered InSe is prone to extreme volumetric changes.…”

“…From the viewpoint of accessible materials, ZnO and Bi 2 O 3 have the advantages of tunable electrical conductivity, high electron affinity, wide bandgap, and environmentally benign, [19][20][21][22] making them promising high-sensitive materials for constructing gas sensors. Furthermore, substantial experimental and theoretical efforts have been devoted to the exploration of a 2D nanosheet (NS) structure for gas sensors due to its large Combination of anti-resonant hollow-core fiber (HCF) and semiconductor nanomaterial is an effective strategy to obtain high-performance gas sensors with exceptional sensitivity and low power consumption.…”

“…This allows 2D electrodes to have enhanced capacities. Due to the reduced distance between those active sites in the nanosheets, fast charging and discharging rates can be achieved [6,7] while good power densities can be also be obtained. MXene is a large family of 2D materials with a general chemical formula of M n+1 X n T x where M is an early transition metal atom, X represents C or/and N atom, and T indicates the surface termination [8,9].…”
