1. Overview US battery developer Lyten has agreed to acquire a Cuberg battery plant in San Leandro that Northvolt is selling off. The move — effectively a Lyten–Cuberg asset acquisition from Northvolt — will redirect Cuberg’s lithium-metal production assets toward…
1. Preface The actual electrode process design, the active material, especially the cathode electrode material conductivity properties is relatively poor, the electronic transmission path is mainly realized through the conductive additives path, such as Figure 1 for the ideal state of…

Abstract The powder compaction process of lithium cobalt oxide (LCO) — the densification behavior of cathode powder under uniaxial compression — determines final electrode density, spring-back, and calendaring pressure windows. Using IEST PRCD3100 Powder Resistivity & Compaction Density System and…
Abstract Powder material compaction density for battery electrode materials is defined as the mass of powder after compression divided by the compressed volume. It differs from true density (no pores), particle density (intraparticle pores only), loose-fill density (no applied pressure),…
Abstract LMFP material (lithium manganese iron phosphate, LiMnxFe1−xPO₄) is an olivine-structured cathode material that bridges the gap between LFP and NCM: it shares LFP’s structural stability and safety while raising the charging voltage from LFP’s 3.4 V to approximately 4.1…
Abstract This study evaluates how premixing conductive agent and binder alters the compaction density and compression behavior of NCM powder. Using the PRCD series compression tester, we compared pure NCM powder with NCM+PVDF and NCM+PVDF+SP (where SP is a carbon-black…
1. Abstract High-nickel cathode materials offer high capacity and favorable cost-per-energy, but their adoption at high voltage and fast charge rates is hampered by structural instability and stress accumulation. This paper presents a metal-cation-induced “three-in-one” surface modification that combines W-doping,…
Abstract Cylindrical cells (sometimes written as cylindrical pressure cells) remain a dominant battery format due to their mature winding process, high automation, and consistent quality. Unlike pouch or prismatic formats, steel shell cylindrical cells have rigid metal enclosures that suppress…
Abstract A current collector in a battery is the metallic foil—copper for the anode, aluminum for the cathode—that conducts electrons between the active material coating and the external circuit. A composite current collector replaces solid metal foil with a “sandwich”…
