System and methods for controlled depowering of automobile batteries

摘要

Methods and systems for depowering an automotive battery in a controlled manner. The methods comprise (i) providing a depowering medium comprising one or more non-ionic electric conductors (for example, a carbon conductor) dispersed in a substantially non-ionic aqueous medium; (ii) contacting terminals of the battery with the depowering medium; and (iii) maintaining contact between the depowering medium and terminals for a period of time sufficient to depower the battery. The systems comprise (i) the depowering medium; and (ii) a container configured to receive a battery and the depowering medium such that the battery body is contacted with the depowering medium prior to the terminals.

主权项

1. A method of controlled battery depowering, comprising:
providing an automotive battery to be depowered; providing a substantially non-ionic depowering medium comprising between 1 and 25 weight percent carbon conductor uniformly dispersed in a substantially non-ionic aqueous medium; contacting positive and negative terminals of the battery with the depowering medium; and maintaining contact between the depowering medium and the positive and negative terminals for a period of time sufficient to depower the battery; wherein increases in battery temperature and evolution of H2, O2, and Cl2 are controlled during depowering.
