Lithium ion battery research

   For the last few decades, new technologies have evolved drastically, and energy storage systems (ESSs) have a most vital role in our everyday life due to on-going demand from electric vehicles to massive smart grids to different electronic systems, like, environmentally sustainable electric vehicles (EVs), hybrid electric vehicles (HEVs), plug-in HEVs (PHEVs), energy storage systems, as well as aerospace and military applications, are gaining popularity in this sense and intending to remove pollution resulting from the use of fossil fuels. Lithium-ion rechargeable batteries (LIBs) in specific, are an effective power source.

    A NASICON-type LiZr2(PO4)3 (LZP) and Li1.2Al0.2Zr1.8(PO4)3 (LAZP) anode materials are synthesized via a facile method, materials were characterized by a variety of structural techniques, investigated the electrochemical performance for rechargeable battery applications. A highly stable rhombohedral phase of LAZP is noticed at room temperature, with a discharge capacity of 909 mAh.g−1, which is 1.6 times higher than that of LZP. Further, the highly stable charge storage performance is observed up to 3000 cycles with a Coulombic efficiency of 99%. For the first time, we investigated the in-situ temperature effect on the discharge capacity of the assembled anode material, found a strong effect on the discharge capacity, and achieved ~120 and 149 mAh.g−1 at 65°C for LZP and LAZP anodes. Furthermore, the real-time charge holding effect of LAZP cell is performed with the computer, the cell worked well in the CMOS battery slot without a CMOS battery error during CPU turn-on condition for 1536 h. In brief, an optimized electrode material of LAZP showed greater stability and capacity with high efficiency compared with LZP even at elevated temperatures. Hence, LAZP may be utilized to fabricate a coin cell for real time applications.
