A startup called ZincFive is set to launch a modular uninterruptible power supply (UPS) for data center computers using the venerable nickel-zinc technology, which it claims is more efficient than lithium-ion.\nNickel-zinc batteries were invented by Thomas Edison in 1901 but fell out of favor to newer designs due to their limitations, such as a low number of charge cycles and their inability to hold a charge for long.\nOn the plus side, the batteries could hold a stronger charge and didn\u2019t use toxic metals like other batteries that make them difficult to recycle. And they are not flammable, something lithium-ion batteries certainly can\u2019t claim.\nZincFive says it has solved the battery charge problems and that its new ZincFive UPS Model 48-3-208 system, set to be unveiled at Data Center World Global conference in San Antonio next week, are more power efficient and safer to use.\nThe company set up shop just two years ago to commercialize nickel-zinc battery technology for a variety of uses \u2014\u00a0from cars to data centers. The company has successfully filed 74 patents and has another 29 pending.\nZincFive says batteries in UPS Model\u00a048-3-208 are safer, maintenance-free\nZincFive claims its batteries are less hazardous than lead-acid batteries typically used in a UPS and that they are physically safer than lithium-ion. They are guaranteed for the life of the UPS, require no periodic maintenance, and support a wide operating temperature range.\n ZincFive\nThe ZincFive UPS Model 48-3-208 is a modular, three-phase system with capacity upgrades in 6kW increments up to a total of 48kW per cabinet. Customers can place precise levels of power protection where and when they need it, the company claims.\nBecause the battery is guaranteed for the life of the UPS, ZincFive\u2019s nickel-zinc batteries eliminate the typical three battery replacement cycles for lead-acid battery-based UPS systems. The power inverters can be replaced without requiring special tools. Capacity upgrades are as simple as adding new inverter modules to the system. And since it uses 60-volt power, it is considered \u201ctouch safe,\u201d meaning you won\u2019t get fried if you put your hand in the wrong spot.\nLast January, ZincFive\u00a0announced new financing to fund further development and that it had shipped test equipment to a \u201cmajor company\u201d data center in December.
