Nanostructured materials afford us new opportunities to improve the current technology for synthesizing Li ion
batteries. Generating nanomaterials with new properties via an inexpensive approach offers a tremendous potential for realizing
high performance Li-ion batteries. In this review, I mainly summarize some of the recent progress made, and describe
the patents awarded on synthesizing nanostructured cathode materials for these batteries via low temperature wet–
chemistry methods. From an economical view, such syntheses, especially hydrothermal synthesis, may offer the opportunities
for significantly lowering the cost of manufacturing battery materials, while conferring distinct environmental advantages.
Recent advances in in-situ (real time) X-ray diffraction for studying hydrothermal synthesis have great potential
for bettering the rational design of advanced lithium-electrode materials. The development of this technique also will be
