ACS Appl Mater Interfaces. 2016 Dec 30. doi: 10.1021/acsami.6b13306. [Epub ahead of print]The high (de-)lithiation potential of TiO2 (ca. 1.7 V vs. Li/Li+ in 1M Li+) decreases the voltage and, thus, the energy density of a corresponding Li-ion battery. On the other hand it offers several advantages such as the (de-)lithiation potential far from lithium deposition or absence of a solid electrolyte interphase (SEI). The latter is currently under controversial debate as several studies reported the presence of a SEI when operating TiO2 electrodes at potentials above 1. Read More
