Revolutionary battery doubles smartphone life (geek, screen, equipment, robot)

[TimJonathan]

MIT offshoot Solid Energy has announced a lithium ion battery that could double battery life.
Their battery design uses an ultra-thin metal anode in place of the standard carbon or silicon-composite anode to halve the size of the battery’s interior. This way they can pack twice the amount of anode inside the cell, doubling the amount of charge it can hold.

This is something that has been tried before but the liquid electrolyte connected to the anode is usually flammable. However, Solid Energy has added elements to the electrolyte to stop the reaction and prevent the battery from exploding.

Solid Energy also says that the battery will be able to be manufactured using technology that already exists, meaning that companies that make lithium ion batteries can start producing these new ones without having to invest in expensive new equipment.

I hear stories every year about new battery tech that will change the way the world works but the end product never materializes. I'll believe it when I see it in a phone from a major manufacturer.

Mr_Geek, au contrarie, they do eventually surface. Lithium battery technology, first seen in 1991, is a big step above NiCad chemistry which was the standard not so long ago.

We need this. Smartphone makers are always trying to design the thinnest phone possible, but they always sacrifice battery life. With these kinds of batteries a 5mm thin phone could probably offer very solid battery life...

I agree with zeppelin171, smartphone makers should give more attention to a solid battery life.
