Typically, slurries for lithium-ion electrodes consist of a solvent, the anode or cathode active material, carbon black to ensure the electrical conductivity and a binder for the cohesion between the particles and the adhesion of the electrode layer to the current collector respectively.
In a battery slurry, these defects can be hugely detrimental to the final performance of the electrode. The slurry must level well and dry into a thin film without defects to ensure an even coating layer and contact area with the electrode.
The electrode-slurries at different AB contents were prepared at the weight ratios Mg-LCO : AB : PVdF = 97 : 1 : 2, 96 : 2 : 2, and 95 : 3 : 2 wt%, respectively. Either of the following two mixing processes (Fig. 1) was applied to prepare the electrode-slurries. Figure 1. Schematic diagrams of the mixing process of the electrode-slurry.
Electrode slurries are a mix of solid, conductive particles along with active materials, polymer binders and a solvent medium.
4. Conclusion The mixing process of electrode-slurry plays an important role in the electrode performance of lithium-ion batteries (LIBs). The dispersion state of conductive materials, such as acetylene black (AB), in the electrode-slurry directly influences the electronic conductivity in the composite electrodes.
The effect of formulation on the slurry properties, and subsequent performance in electrode manufacturing, is investigated for a lithium-ion graphite anode system.
What is electrode slurry ? The electrode slurry consists of the following electrode materials dispersed in an organic solvent. The electrode sheet of the lithium-ion battery is made by applying electrode slurry to the metal foil. Electrode slurry …
