Comparing Cell Energy Density of Two Chemistries

This case study will highlight the importance of reporting new electrode active material performance parameters in full cell architectures. It will also discuss the need to understand the limits of different cell chemistries, and why any extrapolation of future performance must take into account the physical realities of the materials. The performance of electrode active … Read more

Lithium Intensity of Solid-State Batteries

In the ever-evolving world of lithium-ion batteries, solid-state batteries (SSB) are seen as the next generation of lithium-ion batteries. In an SSB, the liquid electrolyte used in conventional lithium-ion cells is replaced by a solid electrolyte capable of conducting lithium. There are three main families of solid electrolytes: oxides, sulphides, and polymers. SSBs promise to … Read more

Effect of Electrode Thickness on Cell Energy Density

In Li-ion batteries, the cathode thickness will heavily influence the energy density of the cell. A thicker cathode means there will be more cathode active material in the electrode. This increases the capacity of the electrode and hence increase the energy density of the cell. However, this relationship is not linear. Using the CAMS model, … Read more

Case-studies on Cell Design and Construction using the CAMS model

The Faraday Institution

This post is a compilation of three separate case-studies covering battery cell design and construction. The data and analysis for these case-studies was carried out using the Faraday Institutions CAMS model. CAMS was designed to rapidly assess the potential energy density of different cell chemistries and cell formats. The model can also be used as … Read more
