1. Author Information and Article Abstract In 2014, Bernhard Bitzer et al. published a method for monitoring the lithium plating of battery cells by in-situ detection of battery swelling thickness changes. When the battery is charged at low temperature or…
Abstract Nano-Carbon coated aluminum foil is an aluminum current collector with a thin conductive carbon layer—applied to both surfaces to reduce interfacial resistance between the foil and the active material coating. Compared to bare aluminum foil, Carbon coated aluminum foil…
Literature Appreciation: Pressure Effect on Mechanical and Electrochemical Properties of Lithium Cobalt Oxide Powder Materials 1. Article Overview The design, manufacture and handling of active substance powders have a huge impact on battery performance. The consistency of the active substance…
1. Introduction: Calendering Compaction as a Key Lever for Electrode Resistance Electrode resistance is a key indicator of electronic conductivity within the coating, closely linked to parameters such as compaction density, porosity, and formulation. During electrode manufacturing, the calendering process,…
Summary Bankruptcy filing by a subsidiary: Northvolt Ett Expansion AB, which was responsible for the “gigafactory” expansion project in northern Sweden, filed for bankruptcy due to project cancellation. The company’s liabilities are estimated to be approximately SEK 2-3 billion (USD…
Abstract The two probe method and four probe method differ primarily in how they handle contact resistance—the impedance at the junction between a measurement probe and the sample surface. The two probe method (also called the two-point probe technique) uses a…
Literature appreciation: Influence of High Intensive Dry Mixing and Calendaring on Relative Electrode Resistivity Determined Via An Advanced Two Point Approach 1. Author Information and Article Abstract Bastian Georg Westphal from the Technical University of Braunschweig, Germany, introduced a fast…
1. Preface The method used in this article is a further improvement on the two-probe method. It adopts a four-wire method plus a controllable pressure double-disc electrode to test the battery electrode resistance, monitor the changes in the electrode resistance…
1. Introduction South Korean battery maker SK On has unveiled a voluntary layoff package and an unpaid-leave-for-study option as it seeks to cut costs and boost agility amid slowing electric vehicle (EV) demand. The measures affect more than 3,500 employees…
1. Abstract Electrode resistance is a sensitive, process-coupled metric that reflects slurry formulation, conductive-additive loading and calendering/compaction conditions. This study uses a controlled four-probe, pressure-applied measurement workflow (BER1300) to quantify how conductive-carbon content and compaction density affect the electronic conductivity…
