| 摘要 |
The present invention relates to an electrochemical cell and a state-of-charge tester therefor, characterised in that the tester is secured to the cell and comprises electrochromic material which changes colour according to the redox potential to which it is subject and which provides an indication of state-of-charge of the cell thereby, said electrochromic material being sandwiched between electrically conductive layers connectable with opposing terminals of the cell, the outermost layer permitting a user to visually determine the colorimetric state of the electrochromic material, the tester preferably being comprised in a label for the cell, the advantage being that the cell cannot act as a heat sink as it would for a thermochromic tester. |
