Hitachi Wizardry Could Lead To Batteries Lasting Twice As Long

We've been playing with Apple's iPad over the past few days (expect a full review soon), and we're amazed by the battery life. But as tech enthusiasts, we're always yearning for more. Hitachi seems to agree with us in thinking that there's really no battery that lasts long enough, and their R&D lab has been working away in an attempt to double the life of convention Li-ion batteries that are used in everything from notebooks to vehicles.

A Japanese report notes that the company is using a manganese positive-electrode material to extend the life, with specifics as follows: 1) replacing part of the manganese contained in the positive-electrode material with another element to stabilize the crystal structure and 2) adding an acid-resistant composite oxide (an oxide that contains more than one metallic element) to the positive-electrode material to reduce the elution of manganese into the electrolyte.



Best of all, Hitachi has created a prototype of the device already, and the conclusion they have drawn is that this technique makes it possible to realize a battery whose "capacity decreases at half the rate and whose life is twice as long (more than 10 years) compared with the company's existing battery cell." It's expected that the new material, if turned into something commercial, would mainly be used for storing energy at renewable energy-based power plant, but there's nothing stopping this from filtering into the world of consumer tech in the future.

Will the next generation iPad last for 20 hours instead of ten? Thanks to Hitachi, we can hope.

It's great they found a way to extend battery life...but, why is the prototype so bulky? That thing would definitely not fit into an Ipad.

That is a picture of a Drill battery, or whatever handheld, cordless construction tool that accepts those kinds of batteries. 

I'm also glad that Hitachi is venturing into this field. Batteries are an amazing invention, and they are crucial for portal computers like the iPad. I trust their R&D team. 

The best way to innovate off of something is to recreate the wheel, so to speak.

This isn't consumer based tech anyway. Your looking at *years* after it comes to market before you will see it in consumer devices. Going back to one of the earlier battery stories, I explained that the most effective way to advance battery tech is to create new materials and compounds.

They start off at very large scale (power gride battery backup) since that is the only place the increased cost to performance can be handled (larger batteries are easier to make and power companies need all the capacity they can get).

Years later, they will have the material cost down and have refined it enough to stick into larger batteries consumers are using. Not cell phones or iPads mind you. Those only recently made the jump to Li-ion batteries. Full size laptops will be the first thing to use them in the consumer space we'll see. Then you have to give them some time to refine it even smaller.

And by that time its time to get them in phones :P lol.

this is interesting, a few weeks ago there was news on a creating longer lasting batteries too, I guess its the year to advance!

Rechargeable is always the way to go.

It is always funny when I see Hippies buying Alkaline batteries, they usually get something like the Energizer E3 Titanium. because they last longer and cut back on the cost to the environment? :P

Every one of my devices has two sets of rechargeables so one is always ready. And I haven't had to buy normal batteries in close to ten years.

All my RC stuff is Lithium, I couldn't imagine weighting it down with anything else. Plus it gives you longer flying time :)

If everyone just went out and bought more of the efficient stuff, they would improve and get cheaper.

The Hitachi Litos have always been good, I am glad to see them leading the way.

The news was talking about the Infini-Battery, the one that can retain its own charge indefinitely!? That I would like to see, although it would put all the battery manufacturers out of business.
