Penn State University have developed a battery which is potentially able to go 1 million miles per charge and will not be so dangerous as the currently available Li-ion batteries.

Safer high energy Li-Ion battery for electric vehicles

Quote:
The battery uses an electric current to heat up in seconds compared to the hours an external heater required. By heating the battery from room temperature to around 140 degrees Fahrenheit—60 degrees Celsius—the battery gets an instant boost in reactivity because the law of kinetics is that reactivity increases exponentially with temperature.

...

The self-heating battery, called the All Climate battery, has been adopted by several car companies, including BMW, and was chosen to power a fleet of 10,000 vehicles that will be used to ferry people between venues at the next Winter Olympics in Beijing.
In my opinion, this will never reach the market. Just like other consumables, you need people to keep on ordering replacements to build your business. It will be sold to the government for them to power off-world electronics which need to last a long time.

Read the article again. You have it hopelessly wrong. The battery is claimed to be go for 4000 charge cycles which would be equivalent to a million miles.

Still good but not outrageous.

A million miles per charge was never realistic. A battery that can be fully recharged in 5-10 minutes, now that would be the difference maker.

From the makers of the 200 mpg carburetor?

1 million miles without a recharge would require an enormously high energy density beyond the domain of chemical reactions, which implies that this would have to be a nuclear battery...
