These batteries can quadruple their capacity after 300 charges
However, the group behind this invention has some of the most successful pioneers in the world of batteries, one of them being inventors of the lithium-ion battery, John Goodenough, He is already 96 years old and continues his research and publications.
In this case, the research has three other scientists, whose research claims to have succeeded in designing a non-flammable solid state lithium battery using electrolytes-based crystal powder. This battery has twice the density of current batteries (theoretically 6000 mAh battery in the same space of a 3000 mAh current), and with a capacity that increases with time.
Specifically, after 300 charge and discharge cycles, the battery capacity increases to quadruple. If these data were not enough, their sustainability has also raised the eyebrow of many scientists: 23,000 full charge cycles, which is fun, considering those around them. 1000 cycles that a current battery can last.
In addition to being safer, lighter and denser, they are lighter
One of the researchers, Maria Helena Braga from the University of Porto, says that this is possible because her glass electrolyte is a material. ferroelectric, which changes its polarization if a field is applied externally. With this, each change you make, each dipole would find its optimal orientation.
Braga says his group has negotiated with several companies that want to use their licensed technology, but they can not advertise who they are or for which products. What she says is that in addition to being denser, more durable and non-flammable, they can do without the stainless steel insulation to which every cell in the battery is subjected because there is no risk of fire by the chain. they would also lighter than the current ones.
The project continues to move forward, and they claim that for 2022 the first commercial products will be available based on this innovation. With regard to the products we might expect, we can not do more than speculation, such as a manufacturer of electric cars, the storage of excess energy from the production on power grids or mobile phones.
