Sodium-ion battery storage for ultra-low temperatures
Researchers from Purdue University have developed a sodium-ion battery pouch cell that can operate reliably at temperatures as low as -100 C, achieving specific energy levels of 96 Wh/kg at room temperature, 74 Wh/kg at -25 C, and 46 Wh/kg at -50 C. The battery was tested with renewable energy sources like wind and solar, showing stable performance in both laboratory and field conditions. This sodium-ion battery technology is considered a more sustainable alternative to lithium-ion batteries due to the abundance of sodium compounds. The research paves the way for sustainable battery energy storage systems in harsh climates and space applications, with potential for solar energy storage in extreme conditions like deep-space missions or cold climates. Scientists are now exploring other solar cell and battery combinations for extreme environments, such as high-efficiency perovskite solar cells with sustainable battery chemistries.

‘When finance flows, ambition grows”: COP30’s call for action
At COP30, discussions highlighted the crucial role of financial mobilization in addressing the climate crisis, with the UN General Assembly President emphasizing the need for up to $1.3 trillion in annual climate finance to reach vulnerable countries. Renewable energy, particularly solar power, has emerged as the fastest-growing and cheapest energy source globally. Climate finance is seen as the "lifeblood" of climate action, capable of turning plans into progress and ambition into implementation. The UN climate chief stresses the importance of demonstrating that climate cooperation is working, as investments made now can shape the growth story of the 21st century, creating jobs, lowering living costs, improving health outcomes, protecting communities, and securing a more resilient, prosperous planet for all. This message is being delivered at COP30 in Belém to drive home the importance of financial support in achieving climate solutions.
