Research progress in nonaqueous lithium/sodium-ion capacitors

Boosting the Pseudocapacitive and High Mass‐Loaded Lithium/Sodium Storage through Bonding Polyoxometalate Nanoparticles on MXene Nanosheets

“…[ 2 ] Nevertheless, neither metal‐ion batteries nor supercapacitors can satisfy the increasing demand of the increasingly electrified society, which largely delays the broad deployment of new energy. [ 3,4 ] As a conceptually new energy storage device, hybrid supercapacitors that smartly combine the advantages of metal‐ion batteries and supercapacitors represent a promising power source for many current and emerged applications. Typically, a hybrid supercapacitor uses an anode of lithium‐ion batteries or sodium‐ion batteries as the energy source and a supercapacitor cathode as the power reservoir.…”

3D Hierarchically Structured CoS Nanosheets: Li+ Storage Mechanism and Application of the High-Performance Lithium-Ion Capacitors

“…Since the first report of LICs with a lithium titanate (LTO) and an activated carbon (AC) by Amatucci and colleagues, diversed anode and cathode materials have been considered for LICs. , However, the entire LIC device has restricted electrochemical properties, which may be related to imbalanced kinetics between adsorption/desorption and the faradic reaction that occurs on the cathode and the anode, respectively. , With regard to the mechanisms of reaction, LICs anode materials are classified into three types. The first type is based on the materials with the lithium insertion reaction mechanism, such as LiCrTiO 4 , LiTi 2 (PO 4 ) 3 , TiP 2 O 7 , Li 2 Ti 3 O 7 , and TiO 2 .…”
