`Almost perfect`battery from MIT

[Secret]

Material scientists have developed a solid-state electrolyte, which can greatly boost modern battery technology. It would allow batteries to endure hundreds of thousands of recharges, pack more juice and be safe from combustion.

Electrolyte is one of key components of a battery, transporting charged ions from one electrode to another during charging and discharging. Modern lithium-ion batteries use liquid electrolyte, but a group of scientists claim to have developed a better all-round solid-state electrolyte. The research was published in Nature Materials in a paper by MIT postdoc Yan Wang, visiting professor Gerbrand Ceder, and five others.

Their invention belongs to a class of materials known as superionic lithium-ion conductors, which are compounds of lithium, germanium, phosphorus and sulfur. Their working solution leads to an “almost a perfect battery” that would be a game changer, according to Ceder.

 

The electrolyte can withstand hundreds of thousands of recharge cycles, meaning a battery made with it would last practically forever. It has superior energy density, packing 20 to 30 percent more energy for a given volume. It is also more stable than a liquid electrolyte, meaning the rare but widely publicized cases of battery combustion like the one that grounded the entire fleet of Boeing Dreamliners would no longer be possible.

More effective but not nearly enough to drive electric cars without packing whole trunk with batteries;)

sadly yea but I hope it will come someday.
