Despite the fact that in modern batteries, we are often not satisfied with their capacity, experts consider their weakest point to be a short service life. Lithium-ion batteries last only a few years, after which their capacity begins to shrink sharply, making them unusable. Experts at Harvard University have found a way to increase the life of batteries in a very unusual way - making their filling liquid.
Given the speed with which alternative energy directions are developing in the world, a natural question arises: where to store huge amounts of collected energy, for example, from a solar station? We need reliable, spacious and, most importantly, durable batteries that can faithfully serve us for decades. Harvard experts have developed a “liquid battery” that can run smoothly for ten years, while over 1000 recharge cycles it loses only 1% of its capacity.
The technology consists in modifying the electrolyte molecules of ferrocene and viogene, making them more resistant to degradation, as well as soluble in water. This solution is an incredibly promising alternative to existing batteries. In addition, water makes batteries much more environmentally friendly, because such a solution is much less toxic than existing solutions. As for the cost of such a solution, scientists are confident that such batteries will eventually become much cheaper than lithium-ion.
To date, researchers from Harvard do not name specific dates when their offspring will be able to enter the market. But the demand for their invention will definitely be, and so on. With clean renewable energy trending today, a growing number of large companies are considering how to store the electricity they collect. And as you know, expensive and short-lived batteries are not so attractive. And remember, just changing our consumption – together we change the world!
