Summary: This paper investigates the impact of internal inconsistency of lithium-ion batteries on their safety performance, using a 3D distributed circuit and electrochemical coupling model that reflects the internal structure. The model is corrected to improve simulation accuracy, and it is found that cell size, tab position, and other structural parameters affect the internal inconsistency. Phenomena like current reversal and local lithium deposition away from the tab position are discovered. The model's correctness and efficacy are further illustrated by reproducing local lithium deposition using controlled charging current.

Summary: A thermodynamically consistent variational framework is developed to explain the metal-insulator transition in polycrystalline LiCoO(2) due to grain boundary lithium segregation, interfacial misorientation, and grain size. High-angle grain boundaries and curved grains favor the transformation to Li-rich phases. Insulating O3(I) phase wets high-angle grain boundaries similar to grain boundary premelting. Above a critical misorientation, the grain boundaries undergo the metal-insulating transition, leading to the formation of an insulating grain boundary network that suppresses the electrical conductivity of polycrystalline LCO. The fabrication of textured LCO microstructures with low grain boundary misorientations can delay the metal-insulator transition.

Summary: By developing a thermodynamically consistent phase field framework, twelve growth mechanisms were identified, including position-dependent large deformation mechanics, plasticity, electrochemistry, and electrodeposition. Specifically, previously reported tip-controlled, base-controlled, and mixed growth mechanisms were further resolved into various sub-mechanisms. It was found that longer dendrites predominantly grow through electrodeposition, while shorter dendrites predominantly grow through plastic flow. Local electrochemical and mechanical interactions induce lateral dissolution and deposition, leading to microstructural changes in the dendrite morphology.
