Hybrids on hold

Yet another caution (see prior post on Toyota delaying Li-ion hybrids).

There are still issues with the problem of "rapid return to neutral state" (aka discharge/heat)

"catastrophic normalization ?"

46 Million Nokia Cell Batteries Defective - New York Times:

"According to a statement by Nokia, short circuits generated by the defective batteries have so far led to 100 incidents of overheating, but none have resulted in serious injury or property damage. Nokia decided on a voluntary replacement program rather than an outright recall because it determined the danger was slight and not imminent, a spokesman said. Mr. Simonson stressed that incidents of overheating tended to occur only when batteries were excessively recharged. “Excessive recharging” means more than 300 recharges, said Arja Suominen, a Nokia spokeswoman."
