Abstract

Summary 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.

Metal–Organic Framework for Aluminum based Energy Storage Devices: Utilizing Redox Additives for Significant Performance Enhancement

“…Rechargeable Al-ion batteries (AIBs) are now among the most explored advanced cell chemistries, which can act as strong competitor to Li-ion technologies. − The advantage of allowing its handling in air makes an AIB an economically and technological viable alternative . Aluminum being widely available becomes a cost-effective resource, with the added advantage of high volumetric capacities (8056 mAh cm –3 ) and high densities (2981 mAh g –1 ) .…”

Bi-Continuous Si/C Anode Materials Derived from Silica Aerogels for Lithium-Ion Batteries

“…Nevertheless, in the etching methods, the use of noxious chemical reagents (such as hydrochloric acid), expensive raw materials (such as silicon powder), and the low yield limit the production of mesoporous silicon anodes. Bhargav Akkinepally et al [22] successfully synthesized a room-temperature-stable pure rhombohedral crystal structure of LZP and LAZP anode materials via a facile solid-state reaction and achieved a high capacity of 909 mAh g −1 at 0.1 C for LAZP with a Coulombic efficiency of 99%. Wang et al [23] synthesized a coating material TiO 2−x /TiO 1−γ N γ (TTN) for Si anodes via a facile and scalable coating method and achieved Si-based LIBs with high energy density and long cycle life.…”
