Abstract

Lithium-ion batteries with a stable circulation capacity, high energy density and good safety are widely used in automobiles, mobile phones, manufacturing and other fields.

Regenerated Graphite-Derived Cellular-Inspired Polydopamine@NiO@Graphite toward Robust Lithium Storage

“…The research of suitable materials for achieving superstability is urgently needed. − The problems of limited insertion sites and insufficient ion extraction from embedded materials may lead to the formation of Li dendrites at a high rate. − Moreover, the lower theoretical specific capacity of graphite anodes than silicon and lithium metal anodes also hinders their wide application. In recent years, researchers have proposed various solutions to the above issues, including graphite surface modification, − anode structure design, − and the preparation of composite materials. , Transition metal compounds are successfully converted to the metallic state through a conversion process with lithium, yielding significant capacity . Materials based on transition metals are widely available and offer a significant amount of untapped potential for development.…”

NiFe-LDH/MXene nano-array hybrid architecture for exceptional capacitive lithium storage

“…LIBs have been broadly applied in electric vehicles, electronic devices, and energy-storage systems due to their large specific capacity, large operating voltage, and long cycle life. [1][2][3] To meet the growing demand for advanced applications, considerable attention has been paid to improving the energy density, rate performance, security, and stability of batteries. 4,5 Twodimensional materials (2D) are prospective candidates as electrodes for LIBs, for example, reduced graphene oxide (rGO) sheets, 6,7 black phosphorus (BP), 8,9 transitional metal chalcogenides (TMCs), 10,11 layered double hydroxides (LDHs), 12,13 and MXenes.…”

Synthetic Strategy of Si@void@C Nanoparticles for High-Performance Lithium-Ion Battery Anodes

“…With the booming of new-energy vehicles, people’s expectations for battery quality are also growing . Researchers are devoted to improving the performance of lithium-ion batteries all around, of which the anode material is one of the most crucial parts. − Silicon anode has attracted great attention because of its good safety performance, cheap price, and low lithiation/delithiation potential (<0.5 V vs Li + /Li). Most importantly, silicon offers an ultrahigh theoretical specific capacity (∼4200 mA h g –1 ), which is close to 10 times that of graphite (∼375 mA h g –1 ). − However, some drawbacks of silicon anode cannot be ignored. , About 300% volume expansion of silicon anode occurs in lithiation/delithiation process, resulting in the pulverization and fragmentation of materials.…”
