    • Disclosed is an electrolyte for batteries, comprising: (a) an electrolyte salt; (b) an organic solvent; (c) a first compound having an oxidation initiation voltage (vs. Li/Li+) higher than the operating voltage of a cathode; and (d) a second reversible compound having an oxidation initiation voltage higher than the operating voltage of the cathode, but lower than the oxidation initiation voltage of the first compound. Also disclosed is a lithium secondary battery comprising said electrolyte. In the lithium secondary battery, two compounds having different safety improvement actions at a voltage higher than the operating voltage of the cathode are used in combination as electrolyte components. Thus, the safety of the secondary battery in an overcharged state can be ensured, and at the same time, the deterioration of the battery can be prevented from occurring when it is repeatedly cycled, continuously charged and stored at high temperature for a long time.

    • The present invention relates to an anisotropic conductive adhesive comprising an anisotropic conductive adhesive combined with a crystalline polymer to realize anisotropic conductivity and PTC (Positive Temperature Coefficient) characteristics at the same time. The anisotropic conductive adhesive having PTC characteristics according to the present invention comprises an insulating adhesive component and a plurality of conductive particles dispersed in adhesive component, in which the insulating adhesive component comprises a crystalline polymer. Since the anisotropic conductive adhesive according to the present invention includes a crystalline polymer, when temperature rises and the volume expands, electrical resistance is rapidly increased, whereby current flow is intercepted resulting in blocking current, providing PTC characteristics acting as a switch. Thus, it shows circuit protection function as well. Accordingly, it is possible to intercept a circuit upon occurrence of excess current without using a separate element for circuit protection such as PTC thermistor.
    • 本发明涉及包含与结晶聚合物组合的各向异性导电粘合剂以同时实现各向异性导电性和PTC(正温度系数)特性的各向异性导电粘合剂。 根据本发明的具有PTC特性的各向异性导电粘合剂包括分散在粘合剂组分中的绝缘粘合剂组分和多个导电颗粒,其中绝缘粘合剂组分包含结晶聚合物。 由于根据本发明的各向异性导电粘合剂包括结晶聚合物,当温度升高并且体积膨胀时,电阻迅速增加,由此截流电流导致阻塞电流,提供作为开关的PTC特性。 因此,它也显示电路保护功能。 因此,可以在不使用诸如PTC热敏电阻之类的用于电路保护的单独元件的情况下在发生过电流时截获电路。
