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

Bipolar Battery

bipolar solid state cell

The bipolar battery essentially moves the series connections inside the cell. This brings a number of advantages and significant challenges. This is shown very clearly in the Toyota battery technology roadmap [1]. The expectation from Toyota is to deliver the following benefits in 2027-2028: Gambe et al [2] show the bipolar semi-solid state cell and … Read more

PowerCo Unified Cell

The PowerCo Unified Cell is a vision from VW to simplify it’s battery packs with one cell design that works across more than 80% of it’s products. When they say design, they actually mean cell format as it appears they are intending on having 3 different chemistries to support the cost / performance trade. Remember … Read more
