Here, we report a new charge protocol for dendrite-free Li-metal battery based on the understanding the effects of over-potential on Li dendritic growth. We demonstrate that when a large over-potential is applied, the deposited Li metal shows a needle-like morphology even though a current density of a cell does not reach the limiting current densit...
Comprehensive Summary Hollow multishelled structure (HoMS) has drawn tremendous attention due to its abundant attractive properties and promising applications. However, for a long time, the limited synthesis method hindered the development of HoMS. The sequential templating approach developed by our group, has greatly enriched its composition and s...

© 2022 Elsevier B.V.For using Li metal anode, controlling Li metal morphology for long-term cycles is an essential requirement, but the porous Li metal easily form due to a dendritic Li growth. Here, we report on a novel strategy to reversibly form a granular Li metal by confining Li deposition sites and controlling the Li metal morphology via a st...
Electrodes with a high areal capacity are critical for developing high-energy-density sodium-ion batteries (SIBs). The free-standing thick electrode is a promising candidate among the state-of-art electrodes, since it has the advantages of high areal mass, binder-free, current-collector-free, and no carbon additive; thus, the whole mass of the elec...

A huge amount of waste silicon powder produced in the solar energy silicon wafer production process causes resource wastage and environmental pollution. As a lithium-ion battery anode, silicon has received widespread attention because of its extremely high theoretical specific capacity, abundance in nature, and low discharge potential. However, the...

A solid-state electrolyte has attracted great interest on energy storage and conversion, especially for lithium metal batteries (LMBs). However, its practical application is limited by poor ionic conductivity at room temperature and dendrite formation. Herein, a polymerized ionic liquid (PIL)-based solid electrolyte with the structure of a semi-int...
