“Batteries improve slowly due to incremental changes from a few legitimate researchers.”
Dude,
1. This is an incremental change, and
2. These are legitimate researchers
Dudette,
It’s not an incremental change that made it to market.
Here’s a publicity release from 2009:
The days of waiting hours to charge a mobile phone or laptop computer could soon be over because of research that could transform battery technology in as little as two years.
Scientists in the United States have invented a battery that can charge in seconds, promising a revolution in power storage that could also help green cars and renewable energy.
The advance allows lithium-ion batteries, the standard variety used in consumer electronics and cells for electric or hybrid vehicles, both to charge and discharge stored energy more quickly than at present.
This should lead to smaller, lighter batteries for mobile phones and other devices, which can be fully charged when plugged in for a few seconds.
