    摘要: An electronic device (220) includes a component (105), such as a microprocessor, that generates heat and an electrochemical capacitor (200) used for thermal management. The electrochemical capacitor (200) has a first region, preferably the perimeter region, including electroactive material (160) and an electrolyte (165) and also has a second region, preferably the inner region, including heat sink material (170). When the component (105) and the electrochemical capacitor (200) are mounted within the device (220), the heat sink material (170) of the capacitor (200) is aligned with the component (105).

    摘要: A method of enforcing a regular manganese dioxide cathode to become gradually and substantially rechargeable is described, where the cathode capacity is increased towards the theoretical capacity of the cathode. The method involves mixing 20-51 wt % MnO.sub.2, 5-25 wt % metallic bismuth and 30-70 wt % graphite powder to form a homogenous mixture, subjecting the mixture to a pressing force to form an electrode and subjecting the electrode to successive discharge/charge cycles at a rate where the cathode capacity becomes greater than 75% of the theoretical capacity after 4-7 cycles. The method provides for a simple and inexpensive way of forming a rechargeable manganese dioxide cathode without complex chemical synthesis.
