Abstract Rechargeable lithium batteries using 5 V positive electrode materials can deliver considerably higher energy density as compared to state-of-the-art lithium-ion batteries. However, their development remains plagued by the lack of electrolytes with concurrent anodic stability and Li metal compatibility. Here we report a new electrolyte based on dimethyl 2,5-dioxahexanedioate solvent for V-class Benefiting from particular chemical structure, weak interaction cation resultant peculiar...
Silicon is regarded as one of the most promising anode candidates for next-generation Li-ion batteries because its high theoretical capacity (4200 mAh g−1). However, main challenge practical application Si anodes huge volume change during (de)alloying with lithium, which leads to pulverization active material and severe loss electrical contact after cycling. Here, we develop hollow porous silicon nanospheres three-dimensional carbon coating SiC transition interlayer (C@SiC@Si@SiC@C) via a...
The swelling of a polymer matrix by ionic liquids and additional lithium salts may lead to the formation ionogel electrolytes. However, introduction ions usually results in decreased lithium-ion transference number, because trapping clusters polymer-ion complexes. Achieving highly efficient migration increasing number (tLi+) are however crucial for successful application Herein, we design crosslinked polyrotaxane network then introduce liquid salt obtain an electrolyte based on principle...
