What is the capacity of C/TiO 2 @Li||LiFePo 4 batteries?

As depicted in Fig. 7 a, C/TiO 2 @Li||LiFePO 4 full batteries display a high initial capacity of 128 mAh g −1, high Coulombic efficiency of 99.2% and stable cycle performance over 250cycles at a current density of 1C (1C = 170 mA g −1).

How efficient is a C/TiO 2 Li battery?

Even the capacity and current density are further elevated to 2 mAh cm −2 and 2 mA cm −2 (Fig. 6 b), C/TiO 2 ||Li battery still maintains highly stable cycle performance and delivers an average Coulombic efficiency as high as 97.7%. Fig. 6 c and d display corresponding charge/discharge curves of Cu||Li and C/TiO 2 ||Li batteries, respectively.

Does 3D freestanding c/tio2 host improve cyclic stability of Li metal anodes?

Moreover, the deposited Li film is also very compact without any sharp dendrites, which may be favorable to improve cyclic stability and lifespan of Li metal anodes. The results remarkably indicate that 3D freestanding C/TiO2 host can effectively alleviate detrimental Li dendrites growth and buffer volume expansion during Li plating (Fig. 5 b).
