Nano-sized inorganic compounds have attracted a great deal of scientific and technical interests owing to their unique physical and chemical properties, which bulk materials may not possess. Because nanoparticles have a large surface area to volume ratio, the
state of the surface molecules plays a key role in determining their properties.
Recently, a surface modification of
nanoparticles with a functional monolayer or a polymer shell has been reported to provide tailored surface properties of nanoparticles. In contrast, a nanoparticle coating on oxides or other inorganic compounds has remained a technical challenge, and has not been reported in the literature.
Recently, we discovered that AlPO4 nanoparticle-coated LiCoO2 showed a remarkable enhancement of the electrochemical and thermal properties, compared to bare LiCoO2 and LiCoO2 coated with other metal oxides.

The
mesopores play an important role in reducing possible
aggregationof Sn particles, and act a "buffer
zone" which accommodates the volume change
of the Sn phase during Li alloying/dealliying.
Our
approach for enhancing the structural stability
of tin phosphate is to incorporate mesoporous structures
as a buffer layer to alleviate the volume expansion
of the tin phosphate anode during lithiation/delithiation.
We
believe that this novel mesoporous tin phosphate/Sn2P2O7
composite has an enormous potential for use in Li-battery
anode material.
