I think the inherent safety of the Mn version is clearly supported by the efforts of Delphi to apply it to vehicles in various ways. I've been told those batteries resemble large blocks of wood, and of course the contained energy must be awesome. A couple of years ago there was also that published article by someone from ULBI describing a large, block-like battery (which I believe was of the Mn type) they had constructed in order to get a very high energy content, and to test its reaction to severe abuse. I recall that they drilled holes through it while fully charged, etc, and only lost a few percent of it's charge capacity. They short circuited it when fully charged, and severely overcharged it as well. According to the story they could only get it to become luke warm, and it eventually just died without any pyrotechnics or other severe reaction. I'm not at all surprised. - T -

Re.: "...overcharging during the recharge cycle, (acc to Lev it could go up to 5V, still no problem) there is not a need for control. UL approval must be easy..." Noticed an error in my earlier post. not a need for control should read not a need for an elaborate control VLNC Mn battery needs a control circuit but it need not be elaborate (and expensive). Simpler control circuits and safer batteries would mean higher margins. Lev described how steep the voltage curve becomes, after 4.5volts, during the recharge cycle and how the control circuits are designed to detect and control. Since it is difficult to control, Li-Co battery is not charged to their full capacity for safety reasons, acc to Lev. The point was: elaborate controls make Li-Co battery more expensive, less competitive. Recall a question about SEC filings vs. Conf. calls. Lev's response: both are true statements of the company status. Ram
