“Carnegie Mellon University researchers have found that the cost savings associated with manufacturing a high volume of batteries for electric vehicles may be nearly exhausted. Mass production lowers cost, say the researchers — but only up to a point.”
This point is level of 200-300 MWh of annual production, which is equivalent to just 8,000+ to 12,500 Nissan LEAFs a year! This would mean that all major manufacturers like Nissan/NEC, LG Chem, Panasonic exceeded this mark long ago
Our results raise questions about whether increasing vehicle sales is the best way to continue to spend limited resources — as opposed to, say, more research on battery technology. For example, we estimate that finding a way to make batteries with thicker electrodes could lower the cost of long-range electric vehicle batteries by as much as 8 percent, while increasing production beyond current levels may only cut costs by less than 3 percent.”
