| 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.
