“…Tape casting is a promising method for the large‐scale production of freestanding ceramic electrolyte films . In solid oxide fuel cells, the construction of a porous anode‐supported electrolyte structure by tape casting is a common method to obtain adequate mechanical strength . A usable thickness of ceramic electrolyte film is dependent on its mechanical property in actual applications, which must adapt to electrolyte production and cell assembly.…”

Ceramic oxide electrolytes are outstanding due to their excellent thermostability, wide electrochemical stable windows, superior Li‐ion conductivity, and high elastic modulus compared to other electrolytes. To achieve high energy density, all‐solid‐state batteries require thin solid‐state electrolytes that are dozens of micrometers thick due to the high density of ceramic electrolytes. Perovskite‐type Li0.34La0.56TiO3 (LLTO) freestanding ceramic electrolyte film with a thickness of 25 µm is prepared by tape‐casting. Compared to a thick electrolyte (>200 µm) obtained by cold‐pressing, the total Li ionic conductivity of this LLTO film improves from 9.6 × 10−6 to 2.0 × 10−5 S cm−1. In addition, the LLTO film with a thickness of 25 µm exhibits a flexural strength of 264 MPa. An all‐solid‐state Li‐metal battery assembled with a 41 µm thick LLTO exhibits an initial discharge capacity of 145 mAh g−1 and a high capacity retention ratio of 86.2% after 50 cycles. Reducing the thickness of oxide ceramic electrolytes is crucial to reduce the resistance of electrolytes and improve the energy density of Li‐metal batteries.

The primary components of SOFCs are the anode, cathode, and the electrolyte. Anode is critical in achieving the effective electrochemical oxidation of fuel; thus, its performance can be improved using homogenous powder synthesized through an appropriate method. Various synthesis methods, including solidstate reaction and wet chemical methods have been used to synthesize anode materials. However, each technique has several advantages and disadvantages.Given that anode is a porous electrode, few criteria, such as high conductivity, tolerance towards carbon deposition, chemical stability, and thermal stability, must be fulfilled. Researchers also modified the existing synthesis method to improve the performance of the anode. In addition, various anode fabrication techniques including physical and colloidal deposition techniques are briefly discussed to understand their effect on the performance of the deposited layers.The aim of this review is to discuss the various anode synthesis and deposition techniques and their influence on the properties and performance of SOFCs.
