Reducing space, power and cooling demands Sodium-ion batteries can and are being deployed in data and communication centers within the “white space” inside IT/Telecom equipment racks – an area where lithium batteries are often not allowed, and lead batteries don’t have the performance required to carry the load. 04 Thanks to their superior safety characteristics, sodium-ion batteries can be deployed in areas where lithium batteries are not allowed and where lead batteries offer insufficient life expectancy to carry the load. The sodium-ion battery’s ability to repeatedly, reliably and safely provide very high peak-power discharges with no potential risk of combustion, explosion, or outgassing under frequent, repetitive use means that it can be deployed in locations and architectures unthinkable for other battery types →04. 03 Capable of tens of thousands of cycles, sodium-ion batteries significantly surpass lead and lithium batteries. These characteristics, particularly with regard to peak-power capacity, enable data centers and other space-constrained mission-critical facilities to free up power and floorspace since peak-power and reserve starting/bridging capacity can be realized in a much smaller volume and do not add any cooling load. 02 Thanks to their high power-to-energy ratio, sodium-ion batteries enable data centers to use less space and cooling than with lead or lithium batteries.įrom a performance point of view, the new sodium-ion battery surpasses both lead and lithium in peak power →02, cycle rate, cycle count, charge/discharge times, →03 round-trip efficiency, safety, and operates over a much wider temperature range. Such batteries are not compromised by dependence on rare earth metals, conflict minerals or questionable supply chain implications. This chemistry is not only safe – passing UL9540A and NFPA855 requirements – but checks the sustainability box as it is comprised primarily of aluminum, manganese, iron, Prussian Blue (a commodity dye), and sodium-ions. These offer extremely low internal resistance, a high cycle-rate, high peak-power capacity, are nonflammable, and exhibit no thermal runaway characteristics by design. This battery utilizes Prussian Blue analogs for cathode and anode. Recently, however, a new battery chemistry has emerged: sodium-ion →01. 01 The unique peak-power capacity of sodium-ion batteries can be utilized to enable new solutions, such as ABB’s Edge distributed data center power architecture. Furthermore, it is not currently feasible to recycle lithium ion batteries and their use in industries such as EVs and mobile phones is constraining supply. The relatively quick acceptance of this battery type has led to emerging safety codes, electrical standards and guidelines that have difficulties keeping up with the specific characteristics of these batteries. Some infrastructure operators are experimenting with a combination of lithium-ion batteries and battery energy storage systems (BESS). Lead acid batteries are well known and, despite drawbacks, are the standard when it comes to short- and medium-duration energy storage for essential operations. There are three battery chemistries that align well with mission-critical electrical systems: lead acid, lithium-ion, and sodium-ion. It is therefore worth looking at which technologies offer the best mix of performance, availability, life cycle and cycle-rate capabilities, energy and power density (two different characteristics), not to mention reliability, safety, sustainability and efficiency. Recent advancements in battery chemistry are opening new horizons in terms of the design and operation of data centers and other critical facilities. In view of these limitations, essential facilities are designed and operated with high levels of redundancy in mind.īut things are changing. However, despite significant efforts to improve them, these workhorses present shortcomings in terms of electrical life, power density and peak power. Jack Pouchet Natron Energy Santa Clara, CA, United States, Dave Sterlace ABB Data Center Solutions Philadelphia, PA, United States, acid batteries have been a mission-critical element for decades in electrical system applications ranging from healthcare and communications to manufacturing and data centers. Such batteries can reliably and safely provide tens of thousands of cycles at very high peak-power discharges with no potential risk of combustion, explosion, or outgassing, thus allowing them to be deployed in locations unthinkable for lead and lithium battery types. A new sodium-ion battery is set to free up space and enhance design flexibility in data centers and other mission-critical facilities.
