Tougher Lithium-Ion Battery Could Last 20 Years

One of the major hurdles facing battery-powered vehicles is the lifespan of the battery. If it’s going to conk out after 10 years, that puts a serious cost consideration on the vehicle. Now, Japanese company Eamex says it has figured out how to greatly increase the longevity of high-capacity lithium-ion batteries.

The company claims its new batteries can cycle through 10,000 charges and last 20 years. How?

It involves stabilizing the electrodes in the tin, which prevents deterioration and allows the batteries to withstand each repeated charge more effectively. Repeated charging and discharging weakens the binding between particles in the tin. Eamex claims its technology — which includes negative electrodes using a tin-coated resin that “accumulates lithium ions coming from the positive electrode” — will help hold the bonding between those particles.

If this is true, it’s exciting stuff. Eamex says it will make a smaller battery first, one that could perhaps power an electric scooter.

Electric cars are coming faster than most people realize.
I'm still predicting over half of all new cars sales will be electric within 10 years.

Looks like the Energizer Bunny has some competition.

I hope that's true.
