Beijing time July 10 news, according to science and technology website BGR reported that the existing battery life is poor is a commonplace problem, if the technology can not be greatly developed in the future, it can not meet the needs of all walks of life. Therefore, in addition to vigorously improving existing technologies, researchers are also actively promoting the development of new types of batteries. Recently, scientists at the Massachusetts Institute of Technology have discovered an interesting method. They created a liquid battery. The power that supplies this battery is omnipresent gravity.
MIT developed liquid battery
This talented idea has also recently appeared in the "Energy and Environmental Science" magazine, and researchers call it "a low-power, pump-free gravity liquid battery."
In fact, liquid batteries have long been not a new concept. Researchers in the 1970s made the prototype of such batteries. In this kind of battery, the traditional positive and negative electrodes exist in liquid form and are separated by a thin film. The particles in the battery generate electricity by continuously moving in the slurry. However, previous liquid batteries have one thing in common: they all require a complicated and expensive system to drive the uninterrupted movement of chemical particles in the battery.
MIT's gravity liquid battery overcomes this shortcoming. The original complex pump system was replaced by ubiquitous gravity. In addition, the rate of power generation can be easily controlled by simply adjusting the angle of the battery (controlling the flow rate of the slurry).
However, like all fresh concepts, this gravity liquid battery is still in the early stages of development, and it is still not possible to save all kinds of "small partners" who are short of power in one hour and a half.
"In the future, we will continue to simplify the system and volume of the gravity liquid battery, introduce a modular design and greatly reduce its cost, and ultimately achieve grid-connected power generation," said R&D personnel. "This new technology will be a powerful complement to the intermittent energy industry such as wind power and solar power generation."
