Abstract Choosing between natural graphite anode and artificial graphite anode materials for a lithium-ion battery comes down to a trade-off across four measurable properties: single-particle crushing strength, powder…
Abstract Battery mechanical properties represent the fundamental physical factors governing lithium-ion battery degradation, cycle life stability, and operational safety. While electrochemical metrics such as specific capacity and ionic…
Abstract Conductive additives are essential components in lithium-ion battery electrodes, typically added at 1–3 wt% to establish electronic conduction networks. The selection and dispersion quality of conductive additives…
Abstract A powder compression test is a mechanical characterization method that applies stepwise pressure to an electrode powder bed and records the resulting thickness change to separate reversible…
Abstract Li-rich manganese-based layered oxide cathodes (LRMs) are promising candidates for next-generation high-energy-density lithium-ion batteries because of their high specific capacity and low cost. But their practical application…
Abstract Powder resistivity measurement systems and powder compaction density testers (collectively referred to as Powder Resistivity and Compaction Density, PRCD systems) characterize the electrical conductivity, compaction behavior, and…
Abstract Sodium-ion battery testing requires a multi-level characterization approach covering four hierarchical scales — particle, powder, electrode, and cell — because sodium-ion battery performance limitations originate at each…
Abstract A recent study published in Nano Materials Science by researchers at Beijing Institute of Technology systematically investigated how external mechanical pressure influences interfacial stability and failure mechanisms…
Abstract Double-layer (dual-layer) coating is a graphite anode manufacturing technique in which a top layer of small-particle, rate-capable graphite (near the separator) and a bottom layer of large-particle,…
1. Introduction Silicon stands out as a highly promising anode material for lithium‑ion batteries due to its theoretical specific capacity of 4200 mAh g⁻¹ and environmental friendliness. However, its practical…
1. Introduction As the new energy market expands and application scenarios diversify, sodium‑ion batteries have attracted considerable attention due to the abundant sodium resources and low material cost.…
Abstract LFP compaction density testing measures how densely lithium iron phosphate (LFP) powder packs under a defined pressure — typically evaluated at 220 MPa using a three-point method…
