MIT chemistry professor suggests Boeing switch from lithium-ion batteries to the heavier but safer nickel metal-hydride battery, a process that could take a year.
"In a large format battery, heat can be generated faster than it dissipates to the surroundings with the result that the temperature of the battery can rise to dangerously high levels which leads to bloating and ultimately fire," he said. But designing, building, and testing a new control system for the NiMH batteries could take a year, Sadoway said. Short of replacing the batteries outright, Sadoway also suggests Boeing create vents in the battery box that allows them to dissipate heat, as well as install temperature sensors to ensure that batteries stay within a safe range.
NY Times: Boeing Battery Was a Concern Before Failure:Because lithium-ion batteries can be dangerously volatile if undercharged, as well as when overcharged, an automatic cutoff is built into the 787 batteries so that if the charge falls below 15 percent of full, the battery locks.

Associated Press said:Airbus abandoned its plans to use lithium-ion batteries for its new A350 airplanes due to the uncertainty surrounding the technology following the grounding of Boeing's 787, the company said. The European aerospace group said Thursday it would revert to conventional nickel-cadmium batteries for the A350. The plane is a wide-body long-range jet rival to the 787 and is expected to make its first flight around the middle of the year. Airbus says it does not expect the battery switch to delay the A350's schedule.
That's probably as much a sales decision as a technical one. By making this switch now, they not only alleviate their customers' fears, but they increase the fear of the B787 customers, which will tend to force Boeing's hand on this issue. Strategically a very smart move, and well-timed.surfingslovak said:Airbus to drop lithium-ion batteries in A350

The above doesn't sound right to me given that we've established from http://www.mynissanleaf.com/viewtopic.php?p=259875#p259875" onclick="window.open(this.href);return false; that the 787 uses lithium cobalt oxide.at the high-end of consumer electronics we have the lithium iron phosphate-dimethyl carbonate-graphite battery known as the Lithium-ion battery, or the battery that powers modern cell phones, laptops, electric cars and is even used in the new Boeing 787. (Yea, the one getting the bad press.)
NTSB: Boeing outsourced key 787 battery safety analysis
The safety agency released its findings Thursday on its investigation of the Japan Airlines 787 fire at the Boston airport on January 7.
Hm, perhaps you were thinking of Honda Fit EV? The i-MiEV always used cells from GS Yuasa, at least if memory serves.cwerdna said:I thought the i-Miev used Toshiba SCiB batteries.
