Sodium-ion home battery delivers 9.7 kWh capacity and promises 20,000 cycles

Home energy storage is being revamped. The 48 V residential energy storage system (RESS) developed by AuroraCell, a Bulgaria-based company, uses sodium-ion chromium oxide (NCO) cathode technology.

Standard lithium batteries are limited by supply problems and have a risk of catching fire. Sodium are potential alternative to solve this crisis. But conventional sodium batteries usually have to compromise between energy density and stability in extreme weather. 

AuroraCell says its specially designed NCO structure overcomes those exact compromises. The unit is said to endure 20,000 cycles at a 100% depth of discharge, a number which exceeds the typical lithium-ion warranty by a number of decades. AuroraCell backs the system with a 20-year guarantee. 

The AuroraCell 9.7 kWh battery stores enough power to run basic home electronics and appliances. It operates as a standard 48-volt system, giving homeowners a dependable backup power supply.

Safety is also one of the main advantages, since the design comes with a guarantee that there will be no fire or explosion. It has both UL9540A and CE safety certifications.

The ability to withstand temperature variations is just as notable. It is capable of discharging without any problems at low temperatures and continues to operate in extreme heat up to 60°C (140°F). 5 kg, can be connected directly to the main 48 VDC hybrid inverters. The brands that are supported are Victron, Schneider Electric, SMA, and Sungrow. Thanks to its modular parallel connections, homeowners can easily increase the system’s capacity.
