A team at Rice University, Houston, Texas has developed a revolutionary solution for battery life and charge rates. Asphalt-based Lithium batteries are based on a new porous carbon anode that could potentially charge high-capacity lithium batteries 20 times faster than currently available commercial lithium-ion batteries.
James Tour, Project lead, said that the capacity of these batteries is enormous and what’s more interesting is that the charge time of these batteries is significantly smaller than the standard batteries available today. These batteries charge from zero to full in just Five minutes! That’s huge. Instead of taking a break of 1.5-2 hours charge time for standard batteries depending upon their size.
The university’s tour lab previously used Gilsonite, the same type that’s used in batteries to capture greenhouse gases from natural gas. However, with Asphalt-based Lithium batteries, they’ve mixed asphalt with conductive Graphene Nanoribbons and coated the composite lithium metal through electrochemical deposition.
Asphalt-based Lithium batteries testing revealed another significant benefit: The carbon mitigated the formation of lithium dendrites. These deposit of the electrolyte and if they extend far enough, they short-circuit the battery, it also explodes or catches fire. Asphalt-derived carbon prevents dendrite formation.
The production of these batteries is also much simpler as there is no need to grow nanotubes from Graphene and the new asphalt-derived carbon take up more lithium metal space. Thus it’s much simpler and cheaper.
With this incredible finding, the commercial possibilities are endless. Asphalt-based Lithium batteries will potentially replace every mobile, laptop, portable device batteries. Based upon larger capacities and faster charging, the foundation of adding up powerful configurations in a device has been laid.
Asphalt-based Lithium batteries will replace the standard lithium-ion batteries. We’ll get faster charge times, cheaper prices, larger capacities. Ultimately raising the bar for much more powerful hardware to be run on the same portable devices. Are you excited for this commercial application of this revolutionary finding?
