First came the material

“It is very easy to make a bad battery out of a good material, but it is impossible to make a good battery out of a bad material.” This truth underlines the universal position of materials chemistry in battery science. In simple terms one may say that at the core of every energy technology there …

In situ study of hydrothermal formation of spinel type LiMn2O4 nanocrystals

Solvothermal reactions have been shown to be a good way to synthesize nanocrystalline materials. Many properties of the product, such as phase composition, crystallite size, morphology and crystallinity, can be controlled by changing and controlling synthesis conditions, such as reaction temperature, heating rate, reaction time, precursor concentration and pH. Ex situ investigation of the effect …

Battery activities at AU: Hydrothermal synthesis of battery materials

Recently, the development of hybrid and electrical vehicles and energy storage devices has raised the requirement on high–rate ability, safety and cyclability of lithium ion batteries. Use of carefully structured nanosized electrode materials is an effective approach to improve the high–rate ability. The AU battery activities focus on nanosized materials, and battery materials are synthesized …
