Electrode architecture and design can greatly affect electrode properties and the effects are sometimes complicated. The architecture of current electrodes is designed mainly based on empirical studies by making trade-offs between battery performance parameters.
The architecture of current electrodes is designed mainly based on empirical studies by making trade-offs between battery performance parameters. Thus, a holistic understanding of the relationships between electrode architecture-property-performance is urgently needed.
Electrode architectural design involves optimising many parameters, such as thickness, porosity, pore size and particle size, the effects of these changes on LIB performance are complicated , , . The architecture of current commercial LIB electrodes is determined by making trade-offs between electrode properties and performance .
As shown in Figure 1, when five batteries using cathodes and anodes with a thickness of 25 μm are stacked, the electrode component accounts for 56% of the total volume. However, in the case of a battery with the same volume, but using a 200 μm thick electrode, the electrode component occupies 88% of the total volume.
Apart from thickness, porosity, pore size, and other architectural parameters, e.g. pore shape, particle size, particle shape are also important in electrode design and need to be carefully adjusted and optimised from a holistic perspective .
From a holistic perspective, the electrode architectural design ultimately needs advanced manufacturing capability to achieve targeted architectures, e.g. precise control of electrode thickness, porosity, pore size and shape.
