“…It is interesting to note that the capacity is retained up to first four cycles with a capacity fade of about 10% at the end of 21 cycles. In addition, the doping of Al 3C lowers the capacity fading to a larger extent [17]. A similar trend was observed by Kalyani et al [12].…”

Spray-Drying of Electrode Materials for Lithium- and Sodium-Ion Batteries

The performance of electrode materials in lithium-ion (Li-ion), sodium-ion (Na-ion) and related batteries depends not only on their chemical composition but also on their microstructure. The choice of a synthesis method is therefore of paramount importance. Amongst the wide variety of synthesis or shaping routes reported for an ever-increasing panel of compositions, spray-drying stands out as a versatile tool offering demonstrated potential for up-scaling to industrial quantities. In this review, we provide an overview of the rapidly increasing literature including both spray-drying of solutions and spray-drying of suspensions. We focus, in particular, on the chemical aspects of the formulation of the solution/suspension to be spray-dried. We also consider the post-processing of the spray-dried precursors and the resulting morphologies of granules. The review references more than 300 publications in tables where entries are listed based on final compound composition, starting materials, sources of carbon etc.

“…However, the high capacity fading on charge-discharge cycling and the low thermal stability in the charged state have inhibited its commercialization. These drawbacks are related to the difficulty in obtaining stoichiometric LiNiO 2 because high temperature treatments have led to the creation of Li 1-x Ni 1+x O 2 , which has a partially disordered cationic distribution at the Li site [3]. Partial substitution for nickel by either a transition or non-transition metal is expected to improve the two dimensional layered structure and the capacity fading upon cycling [4][5][6][7][8][9].…”

Fine-sized LiNi0.8Co0.2-xAlxO2 (0≤x≤0.1) cathode particles were prepared by spray pyrolysis from the spray solutions with and without organic additives. Citric acid, ethylene glycol, and Drying Control Chemical Additive (DCCA) were used as organic additives and improved the morphologies and electrochemical properties of the cathode particles. The LiNi0.8Co0.2-xAlxO2 (0≤x≤0.1) cathode particles obtained from the spray solutions with organic additives were of micro size and had slightly aggregated morphologies. The initial discharge capacities of the LiNi0.8Co0.2-xAlxO2 (0≤x≤0.1) cathode particles obtained from the spray solutions without organic additive changed from 169 mAhg -1 to 190 mAhg -1 when the x changed from 0 to 0.1. However, the initial discharge capacities of the cathode particles obtained from the spray solutions with organic additives changed from 196 mAhg −1 to 218 mAhg −1 . The initial discharge capacity of the LiNi0.8Co0.15Al0.05O2 cathode particles obtained from the spray solution with organic additives was maintained after the 20th cycle at a current density of 0.1 C.
