Whoa. This seems really important. New study suggests that changing the charging protocol from the presently common constant current charge to a high frequency pulsed square wave current could DOUBLE the lifetime of Li-ion batteries.

i.e. the 8 year life of an EV battery back could be extended to a much more reasonable 16 years. That's huge.
