Enhanced rate capability of Li4Ti5O12 anode material by a photo-assisted sol–gel route for lithium-ion batteries

Enhanced rate capability of Li4Ti5O12 anode material by a photo-assisted sol–gel route for lithium-ion batteries

Photo-assisted sol–gel route was developed to prepare nanostructured Li4Ti5O12 anode materials. Resulting Li4Ti5O12 powders were characterized by phase analysis, microscopic morphology observation, and cyclic charge/discharge tests. As lithium-ion battery electrode, synthesized Li4Ti5O12 material by...
