Recently, a research paper whose first author was the doctoral student of chemistry namedLiang Jin who registered in 2014 in School of Science Liang published online on the famous periodical magazine on chemistry Angewandte Chemie International Edition. The title of the paper was Bowl-like SnO2@Carbon Hollow Particles as an Advanced Anode Material for Lithium-Ion Batteries (DOI: 10.1002/anie.2014 07917).The impact factor of the paper that was promulgated lately was 11.336. Jointly guided by the supervisor Zhou Guijiang and professor Ding Shujiang, the work was finished by student Liang Jin in cooperation with professor Xiong Wen (David) Lou from Nanyang University of Technology of Singapore. The School of Science, the National Key Laboratory of the Strength of Metal Materials and the Key Laboratory Imbalanced Synthesis and Control of Materials under the Ministry of Education were the first finishing units of the paper.

Using the nano compound material of hollow structure as the negative pole material of lithium ion battery can greatly relieve the electric chemical performance fall of electrode materials led by volume inflation of metal oxide caused by cycle stress in the process of recharging and discharging. In recent years, professor Ding Shujiang's research group conduct a series of research work to raise the electric chemical performance of the negative pole materials of lithium ion battery by building a hollow nano structure material (Nanoscale, 2012, 4, 3651-3654; Journal of Materials Chemistry A, 2013, 1, 2995-2998).But the introduction of hollow structure caused the fall of the tap density of electrode activating material so the capacity of a single battery dropped. As to this problem, Ding Shujiang's research group and its collaborators creatively pointed out constructing a steamed corn bread shaped nano structure material of hollow bowl shape, which raised the fill density(raised about 30%) and reserved hollow structure.

The research work was funded by the National Natural Science Fund, the international cooperation project of XJTU and Tengfei Professor Talent Plan of XJTU.
