Oh good
Too bad "charging 5x faster" isn't what we want or need (before anyone says "what about cars", the charging time for cars isn't a limitation of batteries, but how much power you can get into it)
What we want are batteries that last more than ~500 charge cycles before becoming noticeably degraded, or store more energy by volume.
Besides, many greatly improved batteries have been "developed" over the past decade, but never seem to find their way into mass production.
Biting the hand that feeds IT
