Abstract

Cadmium telluride (CdTe) nanocrystals (NCs) have generated the interest of researchers as an electrode material in lithium-ion batteries (LIBs) due to a potentially high capacity. CdTe nanocrystals or quantum dots (QDs) were synthesized using laser ablation (Nd: YAG laser at energy 600 mJ by 150 pulse number) to be utilized to form a nanobattery device out of ITO/CdTe/Li: graphene/TPD/Ni. The spectra of the CdTe NCs were assessed using ultraviolet-visible (UV-VIS) and photoluminescence (PL) spectrometers, and the outcomes proved that the CdTe NCs synthesized were nanocrystalline structures. The energy gap (Eg) within CdTe NCs regarded as PL has been identified to be close to 2.33 eV. CdTe NCs produced via laser ablation enhance the functionality of the nanobattery by increasing the carrier's charge mobility and, as a further benefit, by facilitating recombination processes inside CdTe NCs with Li ions. In addition to lighting at (3V), current-voltage (I-V) specifications establish a suitable environment as well as formation. CdTe NCs increased the capability of the nanobattery by increasing the charge mobility of the carrier and, as a result, the interactions between CdTe NCs ions and TPD conductive polymer. Similarly, combining TPD conductive polymers with CdTe NCs semiconductor layers in nanobattery resulted in a complex creation of conductive polymers and semiconductor nanomaterials, resulting in high-performance nanobattery efficiency. The nanobattery mechanism built using materials for semiconductors (CdTe NCs) and (Li-graphene) has successfully run the nanobattery at low voltages while supplying a large current.
