TiO2 hierarchical hollow microspheres with different size for application as anodes in high-performance lithium storage

In the application of lithium-ion batteries, the influences of microsphere sizes are more significant than the secondary nanoparticles size and crystallinity of TiO2-HSs for their transfer resistance and cycling performance, so that the bigger sizes of TiO2-HSs can retain high reversible capacities after 30 recycles.183
