The one problem with gadgets is power. Even if batteries start off long-lasting, after 12 months they start to struggle. But a new material might change that.
A team of researchers from Stanford have developed a new battery electrode that can survive 40,000 charge cycles. That's about a hundred times more than a normal Lithium-Ion battery, and enough to make it usable for somewhere between 10-30 years.
So how does it work? It's down to what it's made from: copper hexacyanoferrate. The structure of the material lets charge-carrying ions move in and out of the electrode easily, and it's extremely rugged, so it degrades at a much slower rate than Li-On batteries. That all means it can charge and discharge rapidly, and lasts for ages.
