Why is there never a single relevant metric mentioned? Here its only cycles and efficiency (which I assume is capacity).

The battery prototype demonstrated endurance, maintaining a stable structure and perfect reversibility over 6,000 cycles — equivalent to more than 16 years of daily operation — with zero loss in storage capacity. WTF!? If this battery is just half as good as they claim, it could be a game changer for storing power for solar and wind!

Less talking about miracle batteries, more making miracle batteries 😡

The title is misleading. “Throughout this period, the system remained free of harmful by-products or sediment while achieving a 99.4 percent leak-proof efficiency. Even at high power outputs, it retained 78.5 percent of its energy efficiency, proving that the design is both reliable and durable.” 99.4% leak proof against material transitioning within the membranes. 78.5% energy output efficiency. And as others have said no useful metrics tbh.
