New batteries for servers arrive

Sony has announced that it will market the battery using a cathode in lithium iron phosphate (LiFePO4) at the end of the month. The first copies of tests have been sent a year ago (see "A battery of 1.2 kWh by Sony") and the Japanese is now ready to put its product on the market. The firm did not give a price but it is contemplated that a kilowatt-hour will be priced around € 2500.

The batteries are designed for data centers, workstations and mobile homes who want to enjoy an alternative source of electricity in case of power failure. The modules used (photo cons) have a capacity of 1.2 kWh. You can customize the system by combining several of them that can be connected in series or in parallel to increase power or autonomy of the whole.

These batteries have the particularity to offer significant power and work at high temperature. This cathode also reduces the charging time (Sony talks about filling in at 90% or more in one hour) and increases the lifespan of the battery that can reach 10 years by the Japanese. We know that Sony is already working on smaller models for mobile consumer products (see "New from Sony lithium batteries).
