Abrégé
Disclosed is an analytic sensitivity expression for parameters of a battery electrochemical model, based on model reduction and reformulation techniques such as the single particle assumption, Padé approximation, and Laplace transform. The analytic expressions of sensitivity are in a compact form with explicit relationship to the current input, which enables the direct optimization of the input-dependent sensitivity. The current optimization with maximum sensitivity may be performed for several critical battery electrochemical parameters, namely a solid-phase lithium diffusion coefficient, a volume fraction of the electrode active material, and a reaction rate constant. The electrochemical parameter may be reliably identified using the optimal current profile.

METHOD FOR MANUFACTURING ELECTRODE ASSEMBLY FOR ELECTROCHEMICAL DEVICE, ELECTRODE ASSEMBLY OBTAINED BY SAME METHOD, AND METHOD FOR MANUFACTURING ELECTROCHEMICAL DEVICE
An electrode assembly manufacturing method according to the present disclosure uses a pre-compressed separator substrate. Therefore, a reduction in thickness of the separator by the pressure applied in a lamination process during the manufacture of an electrode assembly is small. For this reason, the separator of the electrode assembly manufactured by the method exhibits high insulation performance and does not experience a decrease in dielectric breakdown voltage. In addition, even though high pressure is applied during the lamination process, damage to the separator is small, and the processing speed is fast, resulting in process efficiency.

ELECTROLYTE ADDITIVE FOR LITHIUM SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY EACH COMPRISING SAME
The present invention relates to an electrolyte additive for a lithium secondary battery, and a non-aqueous electrolyte for a lithium secondary battery and a lithium secondary battery each comprising same. Specifically, the electrolyte additive for a lithium secondary battery of the present invention is a Lewis base-based compound, and can effectively suppress the elution of a transition metal from a cathode by removing byproducts generated by the decomposition of a lithium salt.
The present invention relates to an electrolyte additive for a lithium secondary battery, a non-aqueous electrolyte for a lithium secondary battery, comprising same, and a lithium secondary battery. Specifically, the electrolyte additive for a lithium secondary battery may comprise a compound represented by chemical formula 1.
The present invention provides a battery pack configured to discharge, when high-temperature gas is generated inside a battery module, the gas to the outside of the battery pack without affecting other adjacent battery modules. The battery pack according to an aspect of the invention comprises: a pack housing; a battery module; and a pack cover which comprises a side venting channel configured to guide gas generated in the battery module to a center space at a position corresponding to the battery module, and a center venting channel configured to guide the gas collected toward the center space to the outside of the pack housing at a position corresponding to the center space, the center venting channel having a volume equal to or larger than that of the side venting channel.
The present invention relates to a battery pack connector comprising a housing equipped with a terminal pin serving as an electrical connection path, wherein the housing comprises: a lower part to which the terminal pin is mounted; and a body part in which a partition wall part is formed to prevent deformation of the terminal pin when an external terminal is coupled thereto and to which the lower part is mounted. Since the lower part and the body part are made of different materials, melting of a battery pack connector may be prevented, and thus thermal runaway occurring inside a battery pack may be prevented from spreading to the outside.
