Toyota is delaying introducing lithium-ion battery-powered hybrids because of safety concerns. Forbes reports that the Japanese automaker is hanging fire (so to speak) due to worries that the cells might overheat or explode. Toyota doesn't expect to have hybrids with Li-Ion batteries until 2011. They've also delayed plans for Tundra and Sequoia hybrids. Whether or not this will affect GM's hopes of lithium-ion powered Volt is yet to be seen. Meanwhile, commenting on an earlier TTAC post, Tesla spinmeister Darryl Siry claims their Roadster's Li-ion battery pack passed UN and DOT protocols for safety "when shipping" which which "can actually be harsher than safety when in a car."
