In the fast-developing world, people must migrate to hybrid electric vehicles with a high energy density of lithium-ion batteries to reduce air and sound pollution primarily. Herein, acid hydrolysis is used to depolymerize vest post-consumer polyethylene terephthalate (PET) bottles, resulting in pure terephthalic acid (TPA). It was used in an acid-base reaction to produce the dilithium terephthalate (Li 2 TP). By using 1 H, 13 CNMR, and FTIR spectroscopy, the obtained TPA and its salt Li 2 TP are thoroughly studied. In terms of electrochemical properties, TPA has a restricted reversible capacity of 102 mAh g À 1 with dramatic fading and a coulombic efficiency of 98.2 % over the 50th cycle at 1 C. The resulting Li 2 TP, displays a three-fold higher reversible capacity of 295 mAh g À 1 , with 99.8 % capacity retention and stable cycling at a similar rate over the 50th cycle. Moreover, computationally found that the charged state of Li 2 TP has a highly unstable structure due to a high steric hindrance and strong similar charge repulsion between lithium ions and it shows bandgap energy 0.2318 eV with four ionic bonds (1.7748 Å) and two new metallic bonds (3.2114 Å), which is 22 times smaller than TPA. Furthermore, Li 2 TP has a lower dielectric constant/loss and higher dipole movement than TPA, with values of 1.32E + 04/1.24E + 03, and 5.93E + 03 respectively, and it improves Li-ion transportation of Li 2 TP in organic electrolytes.

A novel azine monomer and its oligomeric esters were synthesized and applied to chemosensor applications. Among the series of metal ions, the fluorophores show selective and sensitive “turn off” response towards Ag+ ions. The stoichiometry and binding constant are calculated using the Stern‐Volmer equation and Benesi‐Hildebrand plots, respectively. The fluorophore‘s capability for quantitative analysis of Ag+ ions was studied. The quenching mechanism LMCT and PET behind the “turn off” response was confirmed. The conductivity nature of iodine doped and undoped oligoesters was studied. The dielectric behaviour of oligoesters was also studied to determine the possibility of oligoesters in making passive components such as capacitors and resistors. All the results obtained from chemosensor and electrical studies were validated using a theoretical (DFT) analysis using B3LYP/6–311++G(d,p) level basis set.
