New electrolyte tech enables stable operation of high-voltage sodium-ion batteries
U.S. researchers developed a meta-weakly solvating electrolyte that optimizes sodium-ion solvation structure, enabling faster ion transport, reduced side reactions, and improved interfacial stability in high-voltage sodium-ion batteries. This design significantly extends cycle life and outperforms conventional and localized high-concentration electrolytes by promoting more uniform and stable electrode–electrolyte interfaces.
As battery lifespans approach 25 years, leasing will become the dominant financial model, says Unigrid CEO
Battery technology company Unigrid has developed a sodium-ion chemistry that can theoretically last for more than two decades while retaining more than 80% of its initial energy storage capacity. Company CEO Darren Tan says that will inevitably lead to a new zero-down leasing model that locks in a long-term source of revenue while delivering benefits to end users.
