LiFePO4 has some disadvantages, such as poor electrical conductivity (~10-9 cm-1) and the diffusion of lithium ions (Li+) in LiFePO4. These issues result in losses in capacity and rate capability and thus hinder the commercial application of LiFePO4. The use of fine LiFePO4 particles has been proposed to improve Li+ diffusion. Furthermore, surface coating with a conductive material is a commonly used approach to enhance the electrical conductivity of LiFePO4. Among the various possible conductive coating materials, carbon is the most prevalent because of its high chemical stability. Commercially produced LiFePO4 powders are available with a varying amount of carbon content that typically ranges from 1 to 5 wt% because of the differences in techniques used for the synthesis of LiFePO4. For the fabrication of electrodes, electrode materials are typically mixed using either a water-based (aqueous) or solvent-based (non-aqueous) process. The aqueous process is gaining favor and has attracted significant interest because of its environmental consistency and cost considerations. However, the aqueous process has a drawback, i.e., the agglomeration of most oxides, including LiFePO4; until now, the only efficient approach to prevent powder agglomeration has been the addition of an appropriate dispersant to the system. Furthermore, several reports have noted that not all commercial LiFePO4 powders exhibit the same dispersity in aqueous slurries, i.e., notable differences in the dispersion properties of the aqueous slurries prepared with powders from different production lots made by the same supplier may be observed. This variety in the dispersity of LiFePO4 powder in water is an important issue that has caused great concern in LiFePO4-related industries. In addition, the indeterminate dispersity of the powders may cause end users to manipulate them imprecisely resulting in unsuitable electrode slurries. Typical commercially available LiFePO4 powders are obtainable as both dispersions and gels in water. Dispersible LiFePO4 (D-LFP) and gelled LiFePO4 (G-LFP) are two such LiFePO4 powders with the same physicochemical properties of crystallinity, a median particle size (d50) of 2.2 mm, and an approximate carbon content of 1.07-1.20 wt%; these powders were acquired from the same supplier. When we processed them in water by adding the same ingredients, different distinctive flow behaviors of the as-prepared aqueous slurries were observed. The aqueous slurry prepared from the D-LFP powder shows fluidity, whereas the slurry from G-LFP resembled a jelly-like gel. As the formation of powder gel will be detrimental to the electrode-manufacturing process, especially for the slurry-sieving and slurry-casting steps, understanding the cause for the deviation in the dispersity of powders is essential and a prerequisite.
