Uniform second Li ion intercalation in solid state ϵ-LiVOPO4

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...

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...

Todorokite-type manganese oxide nanowires as an intercalation cathode for Li-ion and Na-ion batteries

LiMnPO4 nanoplate grown via solid-state reaction in molten hydrocarbon for Li-ion battery cathode.

Electrochemically active LiMnPO(4) nanoplates have been synthesized via a novel, single-step, solid-state reaction in molten hydrocarbon. The olivine-structured LiMnPO(4) nanoplates with a thickness of approximately 50 nm appear porous and were formed as nanocrystals were assembled and grew into nanorods along the [010] direction in the (100) plane. After carbon coating, the prepared LiMnPO(4) ...
