Abstract: The present disclosure provides a method for predicting a potential energy of a multicomponent material. The method includes encoding a structural information of a multicomponent material in which eigenvector values for each element are calculated using an atom-centered symmetry function (ACSF) of a structural information of atoms constituting the multicomponent material. The method also includes calculating a bond order potential (BOP) parameter for each element using the calculated eigenvector value as an input value and using a different artificial neural network model for each type of atom to construct a physics-informed artificial neural network (PINN) model. The method also includes calculating a bond order potential value for each element to construct a potential energy surface (PES). The method also includes performing structural optimization or physical property prediction of the multicomponent material using a potential energy surface.

Abstract: A battery pack housing for improved cooling efficiency of a battery cell is disclosed. A cooling fluid introduced into a battery pack of the battery pack housing flows to generate turbulence around a battery tab at which high-temperature heat is typically generated. A flow rate and a flow velocity of the cooling fluid may be increased around the battery tab, the cooling fluid may be more actively circulated, and a temperature deviation between cells in the battery pack may be effectively reduced so that performance degradation of the battery pack may be prevented and a lifetime of the battery pack may be increased. In addition, even when the same amount of cooling fluid is used, the cooling efficiency of the battery pack may be improved, and an amount of the fluid needed for cooling may be reduced to simplify an entire system of the battery pack.

Abstract: A device and method use a heat source to generate heat energy and transfer the generated thermal energy to a plurality of electronic components in a non-contact manner through air to cause the plurality of electronic components to vibrate simultaneously. The device and method use a mechanical resonance detector to detect vibration resonances of the plurality of electronic components simultaneously. The device and method use a post-processing processor to compare the detected vibration resonances of the plurality of electronic components with a reference vibration resonance of a normal product to simultaneously determine whether the plurality of electronic components have defective electronic components.

Abstract: The present disclosure relates to a method for preparing an electrolyte and a battery including the same. The electrolyte is prepared by drying a precursor solution containing a lithium-based precursor and a sulfide-based or oxide-based precursor to form a precursor powder, and irradiating microwaves thereto with no heat treatment. Therefore, it is possible to obtain the electrolyte through a simple process and to increase the crystallinity of the electrolyte in a short time, while removing residual organic substances, and thus it is possible to prevent a risk of electrical leakage and generation of an internal short-circuit. It is also possible to significantly improve the charge/discharge performance of a solid-state battery.

Abstract: A method for manufacturing a phase mask and a lens-less camera module comprises the steps of: obtaining a replica mold on which an inverted phase shift pattern is formed in which a phase shift pattern of a master phase mask spaced apart from an image sensor is inverted; calculating a thickness of a phase mask disposed on the image sensor replacing the master phase mask; arranging a photocurable material for implementing the phase mask on the image sensor to a calculated thickness, placing the replica mold on an upper surface of the photocurable material, and then curing the photocurable material; and removing the replica mold from the top of the phase mask, so that the focal distance change or parallel movement does not occur depending on the position of the phase mask.
