“…It is roughly estimated that around 79 percent of PET is left as trash that winds up in landfills. [11,12] Recently, various transition metal oxides, [13,14] nitrides, sulphide, phosphide, metal organic frameworks (MOFs) are studied as alternative anode materials for LIBs due to their high theoretical capacities. [15][16][17] However, the practical capacities are far from the theoretical capacity due to less ionic conductivity, different phase formations, and huge volume expansions during the Li-ion insertion/extraction process as a reason of the fact that the crystal lattice loses its properties remarkably.…”

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.

“…In energy storage systems, sustainable findings are mandatory to overcome energy deficiency for wearable devices and HEVs [2,3] . Various electrochemically active transition metal oxides (TMOs), transition metal sulphides and other inexpensive non‐transition‐based materials have been invented for LIBs and supercapacitors [4–11] . However, the charge‐discharge process leads to large volume fluctuations, which might create contact loss between the electrode material and the current collector due to shattering the electrode materials.…”

The rough spherical-shaped cerium metal-organic framework (Ce-MOF) is synthesized by using solvothermal technique, and after being calcined at 550 °C both with and without tannic acid, CeO 2 and C@CeO 2 are produced. As synthesized Ce-MOF, CeO 2 , and C@CeO 2 are constructed as anodes for lithium-ion batteries (LIBs), also Ce-MOF and C@CeO 2 are investigated for use in supercapacitors. In the case of LIBs, as anode, C@CeO 2 exhibits a good reversible discharge capacity of 137 mAh g À 1 with 99 % coulombic efficiency over 250 cycles at 1 C rate. It demonstrates that the conductivity is greatly improved by the carbon covering than the pristine CeO 2 and Ce-MOF. After the galvanostatic charge-discharge technique at 1 C rate, the morphology size was investigated using FESEM to conform further the following alloying and dealloying mechanism of C@CeO 2 and the dissolution of terephthalic acid (TPA) in the non-aqueous electrolyte that is connected to the core structure of Ce-MOF. In terms of supercapacitors, rough surface morphology improves the electrode electrolyte conduct also the ligand TPA of free terminal acid group attracting K + and forms the COO À K + . Thus, Ce-MOF exhibits a good specific capacitance; after 5000 cycles, it produces 118 F g À 1 at 4 A g À 1 .with 65.2 % capacitance retention. The archived maximum power and energy density outcomes of 10.6 kW kg À 1 and 0.56 Wh kg À 1 at 2 A g À 1 .
