A Method for Rapid Prediction of Cell Lifetime Degradation: Correlating Li Plating and Thickness Expansion
1. Abstract Li plating (lithium metal deposition) is both an accelerator of capacity fade and a latent safety hazard in lithium-ion pouch cells. We demonstrate a fast, non-destructive method that...

The Effect of Electrolyte Additives on Gas Production and Gas Composition of Cells
1. Preface Electrolyte is one of the four main materials of lithium-ion batteries, known as the “blood” of lithium-ion batteries. Electrolyte is mainly composed of organic solvents, electrolyte lithium salts,...

Carbon-Coated Aluminum Foil vs Bare Foil: LFP Electrode Conductivity Compared
Abstract Carbon-coated aluminum foil (CCAF) is an aluminum current collector with a thin conductive carbon layer—approximately 2 µm per side—applied to both surfaces to reduce interfacial resistance between the foil and...

Battery Slurry Viscosity vs. Dispersion: Why More Isn’t Always Better for Rate Capacity
Abstract Battery slurry viscosity and slurry dispersion state are closely linked, but a 2019 study by Kentaro Kuratani and colleagues (Journal of the Electrochemical Society) found that maximizing slurry dispersion does not guarantee...
