Dense All?Electrochem?Active Electrodes for All?Solid?State Lithium Batteries

چکیده
The energy density presents the core competitiveness of lithium (Li)-ion batteries. In conventional Li-ion batteries, utilization gravimetric/volumetric at electrode level is unsatisfactory (<84 wt% and <62 vol%, respectively) due to existence non-electrochemical active parts among 3D porous electrodes, including electrolytes, binders, carbon additives. These are regarded as indispensable irreducible components electronic ionic transport network. Here, a dense “all-electrochem-active” (AEA) for all-solid-state Li batteries proposed, which entirely constructed from family superior mixed electronic–ionic-conducting cathodes, minimize gap between accessible theoretical level. Furthermore, with ionic–electronic-conductive network self-supported AEA cathode, hybrid sulfur (S)-based exhibits high compacted filling rate 91.8%, indicates 777 W h kg?1 1945 L?1 based on total cathodes anodes when 70 °C.

متن کاملNanostructured Lithium-Aluminum Alloy Electrodes for Lithium-Ion Batteries
Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...

متن کاملKinetic characteristics of mixed conductive electrodes for lithium ion batteries
The rate performances of four mixed conductive electrodes (Li4/3Ti5/3O4, LiFePO4, LiCoO2 and LiCo1/3Ni1/3Mn1/3O2) were investigated using alvanostatic charge/discharge, electrochemical impedance Spectroscopy (EIS) and galvanostatic intermittent titration (GITT). These four electrode aterials can be roughly divided into two groups according to the structure change during Li intercalation/extract...
