Scientists add asphalt to lithium batterius that charge up to 20 times faster LAST UPDATED ON OCTOBER 3RD, 2017 AT 7:41 PM BY TIBI PUIU
SNIPPET:
Just a touch of asphalt is enough for high-capacity lithium metal batteries to charge 10 to 20 times faster than the commercially available lithium-ion variety. Additionally, the novel batteries last longer and are safer than current alternatives.

Agelbert NOTE: Off the shelf Lithium ion batteries now use carbon anodes, so this modification is not that big or expensive of a change. That said, I am a bit skeptical because faster charging does not give any guarantee of avoiding dendrite formation that degrades the batteries. The scientists claim the asphalt doping prevents dendrite formation. Maybe during the charge itself, but what about while it is sitting? I am not convinced by their assurances.
Repeated faster charging might even cause the dendrites to grow faster, so I will adopt a wait and see attitude in regard to this innovation.
