    摘要: The invention is a lithium secondary battery that prevents electrolyte and internal gas leakage by durably sealing the electrolyte injecting hole. The lithium secondary battery consists of a battery can, which contains a polar plate set with an anode plate, and a separator inserted and installed inside the battery can. The opening of the battery can has a cap assembly with an electrolyte injecting hole so that the can interior can be sealed. To seal the battery can, a rivet shaped sealing member is inserted in the electrolyte injecting hole. The sealing member is placed in contact with the cap assembly at an area surrounding the electrolyte injecting hole and affixed to the cap assembly.

The present invention provides a prismatic lithium ion battery in which improved safety is provided to a battery itself as well as its battery pack by mounting a jelly roll into a prismatic can with surfaces with recessed portions so that battery volume change due to the electrode expansion and pressure rise inside the battery is restrained. Furthermore, a prismatic lithium ion battery of the present invention improves the cycle life characteristics of a battery by alleviating the jelly roll deformation caused by the expansion and contraction of a jelly roll of a lithium ion battery due to continuous charging and discharging. Accordingly, lithium metal can be uniformly and stably adsorbed in and detached from a jelly roll.

    摘要: An apparatus estimates SOH of a battery based on a battery voltage variation pattern. A data storing unit obtains and stores battery voltage, current and temperature data from sensors, at each SOH estimation. A first SOC estimating unit estimates first SOC by current integration using the battery current data. A second SOC estimating unit estimates open-circuit voltage from the voltage variation pattern, and calculates and stores second SOC corresponding to the open-circuit voltage and temperature using correlations between the open-circuit voltage/temperature and SOC. A weighted mean convergence calculating unit calculates and stores convergence value for weighted mean value of ratio of the second SOC variation to the first SOC variation. A SOH estimating unit estimates capacity corresponding to the weighted mean convergence value using correlation between the weighted mean convergence value and the capacity, estimates relative ratio of the estimated capacity to an initial capacity, and stores it as SOH.
