In the light of wireless and non-fossil society based on portable electronics, electric vehicles, and smart grids, secondary batteries with higher energy density, faster charge, and safer operation are pursued persistently [1].Nowadays, commercial lithium (Li)-ion batteries have been practically applied in our daily life.However, the energy density of Li-ion batteries based on intercalation chemistry is approaching to the theoretical value due to the limited specific capacity of graphite anode (372 mA h g-1) [2].In order to further improve the energy density of secondary batteries, Li metal anode was revisited owing to its extremely high theoretical specific capacity (3860 mA h g-1) and low reduction potential (-3.04 V vs.standard hydrogen electrode) [3].Moreover, Li metal anode can be combined with different types of cathodes, such as intercalated cathodes (e.g., LiFePO4 and LiNi0.5Co0.2Mn0.3O2 (NCM523)) and conversion cathodes (e.g., sulfur and oxygen) to construct various next-generation battery systems [4,5].

Silicon has a large impact on the energy supply and economy in the modern world.In industry,high purity silicon is firstly prepared by carbothermic reduction of silica with the produced raw silicon being further refined by a modified Siemens method.This p
Surface passivation via post-treatment with organic reagents is a popular strategy to improve the stability and efficiency of perovskite solar cell.However,organic passivation still suffers from the weak bonding between organic chemicals and perovskite la
Due to the sufficient ion diffusion channels provided by the large interlayer spacing,layered silicates are widely considered as potential anode materials for lithium ion and sodium ion batteries.However,due to the poor electronic conductivity,the applica
Conventional Li-O2 battery is hardly considered as a next-generation flexible electronics thus far,since it is inflexible,bulk,and limited by the absence of the adjustable cell configuration.Here,we report a binder-free and flexible electrode of x wt％ MoO
