An experimental protocol is developed to measure the shear strength of NMC811 single crystals within cathode a lithium-ion cell. The placed upon set thick metallic substrates that possess wide range indentation hardness. For each choice substrate, top surface indented by Vickers indenter sufficient depth layer subjected an approximately spatially uniform compressive normal traction equal hardne...

The demand for lithium ion batteries (LIBs) in the market has gradually risen, with production increasing and expected to be boosted through massive emergence of gigafactories. To meet industrial needs, development digital twins designed accelerate optimization LIB manufacturing processes is essential. We report here a new three-dimensional physics-based modeling workflow able predict influence...

Abstract In this second of series papers, the use two physics-based models to analyze discharge performance a set high-energy-density electrodes is discussed. The measured parameters from first part implemented into these models. First, regular Newman pseudo-2D model shows large discrepancy against experimental values. Then, an extension considering particle agglomeration due calendering effect...

The continuing rise of electric mobility is driving demand for lithium-ion batteries to unprecedented levels. To ensure efficient production high quality, yet affordable battery cells, while making the best use available raw materials and processes, reasonable quality assurance criteria are needed. A step particular importance, affecting all downstream lies in electrode manufacturing including ...

Previous investigations on porous Li(Ni x Co y Mn z )O 2 (NCM) particles with shortened diffusion paths and an enlarged interface between active material electrolyte show improved rate capability cycle stability compared to compact particles. Due the additional intragranular porosity of material, also pore structure overall electrode, as consequence, ionic transport in phase is altered. In addi...
