The bulk electric field with an average strength of 2.1 × 10 2 V m −1 throughout the TiO 2 film was built up by the aligned dipole moment produced in the distorted TiO 6 unit cells.
The electric field stemmed from dipole moment in the bulk was evidenced by Kelvin probe force microscope (KPFM). The average electric field strength throughout the Li-TiO 2 film was measured as high as 2.1 × 10 2 V m −1, compared with the negligible electric field measured in pristine TiO 2 film.

This result highlights the significant role of bulk electric field in the PEC process.
Symmetrical batteries prepared with K-BVC metal anodes have extremely long cycle lives and low voltage polarizations. The battery assembled based on the K-BVC metal anode and PB cathode exhibits excellent rate performance and cycle stability.
In comparison, the bare K/PB battery has a capacity of only 51 mAh g −1 at a current density of 500 mA g −1, and the Coulombic efficiency of the K/PB battery drops sharply after 50 cycles. In addition, the specific capacity of the full cell increases slightly during cycling, which is due to the change of the full cell charge-discharge platform.
