Boston Power’s Sonata Battery Reaching New Heights
Lithium-ion battery manufacturer Boston Power has made some well-publicized improvements on their latest battery, one which they are calling the Sonata. Boston-Power claims that the Sonata battery will be able to hold strong for up to 3 years or 1000 charges, unlike the standard lithium- ion battery that usually lasts 1 year and up to 350 charges. These specs are much higher than their previous batteries, and Boston-Power is so sure of the Sonata that they are putting their money where their mouth is. Boston-Power guarantees the Sonata, and offers a warranty stating that if their battery does not last beyond the 3 year mark it will be replaced.
The secret behind the success of this long lasting battery is in the chemistry, according to Boston Power CEO Dr. Christina Lampe-Onnerud. “Instead of using carbon steels that are very tough materials . . . we have deployed an aluminum can that basically allows for lighter weight in general, better heat dissipation and much more flexibility in the metal so it allows this battery to basically breathe when you exercise it,” she says. The Sonata uses prismatic cells inside the pack instead of the typical cylindrical cells. This design allows more room for the microns to swell/breath during its charge/discharge cycles. The prismatic design also gives the microns a place to go due to the added space, leaving less wear and tear on the battery and allowing a longer lasting life.
The first Sonata batteries have been being sold by HP under the name HP Enviro. It’s name was derived from the fact that with the longer life span comes less waste and replacement purchases. The HP Enviro is an upgrade from the HDX, G series, DV and also its Compaq CQ Series notebooks and has been available on the market since Spring 2009.
