An Advanced Microstructural and Electrochemical Datasheet on 18650 Li-Ion Batteries with Nickel-Rich NMC811 Cathodes and Graphite-Silicon Anodes

摘要: Cylindrical lithium-ion batteries are used across a wide range of applications from spacesuits to automotive vehicles. Specifically, many manufacturers producing cells in the 18650 geometry i.e. steel cylinder diameter and length ca. 18 65 mm, respectively. One example is LG Chem INR18650 MJ1 (nominal values: 3.5 Ah, 3.6 V, 12.2 Wh). This article describes electrochemical performance microstructural assembly such cells, where all under-pinning data made openly available for benefit wider community. The charge-discharge capacity reported 400 operational cycles via manufacturer's guidelines along with full-cell, individual electrode coating particle 3D imaging. Within data, distinction between protocol transition, beginning-of-life (BoL) loss, prolonged degradation outlined and, subsequently, each aspect characterization broken down into key metrics that may aid understanding (e.g. layers, thickness, areal loading, size shape). All information summarized quick-access advanced datasheet order provide an initial baseline guide research paths, inform experiments computational modellers.
