3 - Index 此档将提供电容器 (EDLC) 基本应用开发指南.若在开发使用过程中遇到问题且在此文件中找不到相 关解决方案,请直接与我们联系. This document provides basic guidelines for application development using capacitors, also known as EDLC. If questions arise during your development process and are not answered in the document, please contact us directly. 寿命 Life Time EDLC具有二次电池更长久的寿命,但是其寿命也不是无限长的.EDLC基本的寿命终止失效模式 为等效串联电阻 (ESR) 升高和/或容量的降低.实际的寿命终止标准取决於应用要求.长期置於高 温下,高电压和超电流将会导致ESR升高和容量降低.这些参数的降低将可延长超级电容器的寿 命.一般来说,圆筒型EDLC具有与电解电容器相类似的构造,有电解液、铝壳和胶粒.多年使用后, EDLC内电解液也会干涸,如同电解电容器一样,导致ESR升高,寿命终止. EDLC has a longer life time than secondary batteries, but their life time is not infinite. The basic end-of- life failure mode for an EDLC is an increase in equivalent series resistance (ESR) and/or a decrease in capacitance. The actual end-of-life criteria are dependent on the application requirements. Prolonged exposure to elevated temperatures, high applied voltage and excessive current will lead to increased ESR and decreased capacitance. Reducing these parameters will lengthen the life time of a supercapacitor. In general, cylindrical EDLC have a similar construction to electrolytic capacitors, they have a liquid electrolyte inside an aluminum can sealed with a rubber bung. Over many years, the EDLC will dry out, similar to an electrolytic capacitor, causing an increase in ESR and eventually end-of-life. 电压 Voltage EDLC是有额定的推荐工作或使用电压的.电压值是基於其在最高额定温度下最长寿命来设定的. 如果使用电压超出了推荐电压,其结果将会导致寿命缩短.如果电压持续过高,EDLC内将会产生 气体,导致漏液或防爆阀破裂.但EDLC是可以承受短期过电压的. EDLC are rated with a nominal recommended working or applied voltage. The values provided are set for long life at their maximum rated temperature. If the applied voltage exceeds the recommended voltage, the life time will be reduced. If the applied voltage is excessive for a prolonged time period, gas generation will occur inside the EDLC and may result in leakage or rupture of the safety vent. However, short-term over voltage can usually be tolerated by the EDLC. 使用指南 Application Guidelines -

4 - Index 极性 Polarity EDLC的电极设计具有相对称的特性,即两极有相似的成分.在EDLC初次组装时,任一电极都可定 为正极或负极.但EDLC在100%质量测试时第一次充电,其电极将会形成极性化.每一EDLC都有 负极框或符号来标识极性.尽管其可以降低到零电压,其电极还是会保留非常少的电荷.虽然之前 充电的EDLC会放电至C2.5V且在容量或ESR方面至极低,但还是不应进行反极使用. EDLC are designed with symmetrical electrodes, meaning they are similar in composition. When an EDLC is first assembled, either electrode can be designated positive or negative. Once the EDLC is charged for the first time during the 100% QA testing operation, the electrodes become polarized. Every EDLC has a negative stripe or sign denoting polarity. Although they can be shorted to zero volts, the electrodes maintain a very small amount of charge. Reversing polarity is not recommended, however previously charged EDLC have been discharged to C2.5V with no measurable difference in capacitance or ESR. 注: 在一方向上保留的电荷越久,EDLC就变得越极性化.如果在一方向上长期充电后再进行反向 充电,EDLC的寿命将会大大地缩短. Note: The longer they are held charged in one direction, the more polarized they become. If reversely charged after prolonged charging in one direction, the life of the EDLC may be shortened. 环境温度 Ambient Temperature DRE系列电容的标准温度范围为C25?C~+70?C,DRL系列电容的标准温度范围为C40?C~+60?C. 温度及电压会对EDLC寿命有影响.一般来说,环境温度每提升10?C,EDLC寿命就会缩短一半.因此,建议尽可能在最低温度下使用EDLC以降低内部劣化与ESR升高.在低於正常室温环境下,可 使用稍高於额定工作电压而不造成内部劣化和寿命缩短.在低温下提升使用电压将可抵消ESR的 升高.高温下ESR的升高会导致EDLC永久性劣化/电解液分解.在低温下,因电解液粘性的提升及 离子的缓性移动缘故,ESR升高只是一种短暂现象. The standard temperature range is C25?C to +70?C for DRE series or C40?C to +60?C for DRL series. Temperature in combination with voltage can affect the life time of an EDLC. In general, raising the ambient temperature by 10?C will decrease the life time of an EDLC by a factor of two. As a result, it is recommended to use the EDLC at the lowest temperature possible to decrease internal degradation and ESR increase. At temperature lower than normal room temperature, it is possible to apply voltages s........
