Topochemical Deintercalation of Li from Layered LiNiB: toward 2D MBene

Topochemical Manipulation of Layered Perovskites

XAFS Characterization of Li Deintercalation in Rechargeable Lithium Battery Materials, LiCoO2-LiNiO2

111 sitzr measurements of the Ni and Co K-edge XAFS spectra of Li1.~Ni02 and Lil.,CoOz as a function of x were successfully carried out for the first time using an electrocl~emical ceii. It is observed that a local Jahn-Teller distortion of the Ni06 octahedron in LiN102 was reduced with deintercalation of Li which caused oxidatiou of the Jahn-Teller d7 ~ i ~ * ion to do Ni4+i011. A substitution...

Layered solids: from lubricants to 2D electronic materials*

FIG.1. WSe2 field-effect transistor with conducting NbSe2 leads in side view. Atomic-model representation of the NbSe2/WSe2 interface (top) and schematic structure of the device (bottom). (From Ref. [2]). Transition metal dichalcogenides (TMDs) with the chemical composition MX2 (M=Mo,Ti and X=S,Se) are layered solids known for their excellent behavior as dry lubricants. Interestingly, TMDs have...

Electrochemical Li Topotactic Reaction in Layered SnP3 for Superior Li-Ion Batteries

The development of new anode materials having high electrochemical performances and interesting reaction mechanisms is highly required to satisfy the need for long-lasting mobile electronic devices and electric vehicles. Here, we report a layer crystalline structured SnP3 and its unique electrochemical behaviors with Li. The SnP3 was simply synthesized through modification of Sn crystallography...

Topochemical photopolymerization of diolefin crystals

Topochemical [2+2] photocyclo-dimerization and -polymerization of olefinic derivative crystals are reviewed from the points of view of synthetic and structural chemistries. In 1964 Schmidt and co-workers established the topochemical concept concerning to the photoreactive olefinic crystals: the topochemical reaction tends to occur with a minimum of atomic and molecular motion. The first example...
