New Silver-zinc Battery provides longer Battery Life for Laptops & Mobiles

Battery

Silver-zinc batteries pack more energy than lithium-ion batteries, giving laptops 40 percent more run time, according to Dueber. If a laptop runs for two hours with a lithium-ion battery, it should run for closer to three hours with a silver-zinc battery.

The batteries will be available in consumer and business laptops from major PC makers starting in August, according to Ross Dueber, the CEO of ZPower, although he declined to name any of the vendors on Thursday.

The battery’s water-based chemistry also makes it nonflammable, compared to lithium-ion, which uses dimethyl carbonate, a flammable liquid. Cells can go off “like firecrackers” in lithium-ion batteries.

It also remains to be seen if silver-zinc batteries can compete on price, since lithium-ion is relatively cheap. The silver-zinc batteries contain silver, which can be expensive.

Intel Unveiled Low-Cost Laptops for $300

Intel

Intel Corp. unveiled new low-cost laptops for schools on Wednesday, adding bigger screens and more data storage capacity as the chip maker ratchets up its rivalry with the One Laptop per Child organization, which sells a competing machine.

Intel’s new Classmate PCs – slated to go on sale in April for between $300 and $500 – reflect the company’s growing efforts to sell computers equipped with its own chips to schools in developing countries, a battleground for technology companies because of the millions of people there just coming online.

But the target market has expanded to include kids in the U.S. as potential users of cheaper, stripped-down machines.

Other tweaks to the Classmate that Intel announced Wednesday from its developer forum in Shanghai include the availability of both 7-inch and 9-inch screens, a 30 gigabyte hard disk drive and an integrated Web camera.

At the developer forum, Intel executives also rolled out five new processors under the “Atom” brand name. The chips are designed for pocket-size Internet devices. The chips come in speeds up to 1.86 gigahertz while using less than 3 watts of power.

Intel said its Classmate PCs will eventually use Atom processors.

Classmates are based on Intel’s design and include its processors, but they are built by other manufacturers and sold under a variety of brand names. The first generation went on sale in March 2007 with the 7-inch screen and fewer functions. Intel said it has sold “tens of thousands” of the machines but declined to provide more specific data.

Intel and OLPC have feuded furiously over their competing products.

Intel claimed it couldn’t continue cooperating with OLPC when founder Nicholas Negroponte demanded Intel stop selling Classmates overseas. Negroponte said the dispute stemmed from Intel sales reps disparaging OLPC products while pushing Intel’s own machines.
