Editorial: Energy Storage Systems Beyond Li-Ion Intercalation Chemistry

High performance Li-ion sulfur batteries enabled by intercalation chemistry.

The unstable interface of lithium metal in high energy density Li sulfur (Li-S) batteries raises concerns of poor cycling, low efficiency and safety issues, which may be addressed by using intercalation types of anode. Herein, a new prototype of Li-ion sulfur battery with high performance has been demonstrated by coupling a graphite anode with a sulfur cathode (2 mA h cm(-2)) after successfully...

High-rate electrochemical energy storage through Li+ intercalation pseudocapacitance.

Pseudocapacitance is commonly associated with surface or near-surface reversible redox reactions, as observed with RuO2·xH2O in an acidic electrolyte. However, we recently demonstrated that a pseudocapacitive mechanism occurs when lithium ions are inserted into mesoporous and nanocrystal films of orthorhombic Nb2O5 (T-Nb2O5; refs 1,2). Here, we quantify the kinetics of charge storage in T-Nb2O5...

Nanoscale spinel LiFeTiO4 for intercalation pseudocapacitive Li(+) storage.

Intercalation pseudocapacitive Li(+) storage has been recognized recently in metal oxide materials, wherein Li(+) intercalation into the lattice is not solid-state diffusion-limited. This may bridge the performance gap between electrochemical capacitors and battery materials. To date, only a few materials with desired crystal structure and with well-defined nanoarchitectures have been found to ...

DFT analysis of Li intercalation mechanisms in the Fe-phthalocyanine cathode of Li-ion batteries.

New materials with high intercalation capacity are needed for cathodic materials in order to overcome small capacities at high discharge rates in Li-ion batteries. High intercalation capacities have been reported in the experimental setup using iron phthalocyanine (FePc) as cathodic material; however the real intercalation capacity and the chemistry occurring during the intercalation process ar...
