“…This activation behavior comes from the AGACEI rearrangement of capturing Li + by the carbonyl groups. Many literature studies have published that this carbonyl group not only provides high ionic transport but also delivers capacity in accepting alkaline or alkali-earth metal ions for energy storage. The second is the inhibition of electrolyte decomposition on the surface, which avoids the formation of low ionic conductivity compounds like LiF and LiOH. In Figure , the XPS results demonstrate that AGACEI@LiCoO 2 shows low intensity of O 1s and F 1s spectra correlated to those compounds aforementioned; this will be discussed in the next part.…”

“…The first discharge curves of 3‐TCOOLi and P3‐TCOOLi electrodes have sloped voltage plateaus below 1.0 V and 0.8 V, respectively. But there is no obvious charge‐discharge voltage plateau in the subsequent charging and discharging processes (Figures 4a and 4b), which is a common phenomenon in organic anode materials [43,44] . The initial charge/discharge specific capacities of 3‐TCOOLi and P3‐TCOOLi electrodes at 50 mA g −1 are 344.7/621.6 mAh g −1 and 606.7/719.2 mAh g −1 , respectively, and the corresponding Coulombic efficiencies are 55.5 % and 84.4 %, respectively.…”

[43,44] The initial charge/discharge specific capacities of 3-TCOOLi and P3-TCOOLi electrodes at 50 mA g À 1 are 344.7/621.6 mAh g À 1 and 606.7/719.2 mAh g À 1 , respectively, and the corresponding Coulombic efficiencies are 55.5 % and 84.4 %, respectively. Subsequently, the Coulombic efficiency gradually increased until close to 100 %.…”

“…After 200 cycles, the O 1s spectrum in Figure 10d shows peaks at 531.2 eV is assigned to Li 2 CO 3 , which is the major component of the SEI. [45][46][47][48][49] Another two peaks at 532.1 and 533.5 eV are indicated the presence of CO and C-O-C bonds of the organic polycarbonate SEI in the blank-Si electrode. Similarly, the PBCS-Si electrode contains peaks at 530.7, 532.3, and 533.5 eV features of Li 2 CO 3 , CO, and COC bonds, indicating the SEI as well.…”
