The sodium trifluoromethanesulfonate-dissolved ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide is intended to replace sodium chloride-saturated sodium tetrachloroaluminate as the catholyte in a sodium copper chloride battery operating at 175 °C.
The cathode provides a high energy density of 374.7 Wh kg1 and a high specific capacity of 141.4 mAh g1. Moreover, with an average coulombic efficiency of as high as 92.1% after 50 cycles, the capacity retention increases. The analysis of the cathode and solid electrolyte collected after 50 cycles reveals that the accumulation of a significant amount of non-conductive copper chloride in the three-dimensional network structure of the copper foam and the loss of -alumina in the solid electrolyte during the charge/discharge process are responsible for the battery’s degradation mechanism.
Although having a pretty well-known redox system, sodium-metal halide batteries are not widely used, despite being one of the most appealing technologies for stationary electrical energy storage. The high operating temperature is one of the barriers preventing commercial adoption. Here, we show that extremely high energy density may be achieved while operating planar sodium-nickel chloride batteries at a temperature of 190 °C.
For planar sodium-nickel chloride batteries operated at 190 °C over a long-term cell test, a specific energy density of 350 Wh kg-1, higher than that of conventional tubular sodium-nickel chloride batteries, is obtained.
This is attributed to the slower particle growth of the cathode materials at the lower operating temperature.The findings presented here show that planar sodium-nickel chloride batteries operated at a medium temperature could significantly improve battery energy density, cycle life, and material costs for this conventional energy storage technology.
The Global Sodium-copper chloride battery market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
As the world increasingly looks beyond lithium, where Faradion is leading the charge, this will help the company establish itself as a pioneer in next-generation battery technology. Faradion’s technique offers comparable performance to current chemistries while eliminating the use of pricey components like cobalt and substituting sodium for lithium, which is more available and sustainable.
Due to its improved safety and increased thermal stability, AMTE Power has designated its sodium-ion product as “Ultra Safe”. The Ultra Safe product provides clients and users with safer solutions for transportation and maintenance thanks to Faradion’s patented zero-volt technology.
Powders for sodium-ion batteries from NEI are offered in weights of 50g, 100g, 250g, 500g, and 1 kilogramme or more. Secure Storage & Handling Precautions Always wear the appropriate personal protection equipment.Put in place suitable exhaust ventilation where dust is produced. Keep the container securely shut and in a dry, well-ventilated area.For detailed safety information on this matter, consult the SDS.
