And how long before some punk tries to smoe one of these batteries ?

That’s all good, but there isn’t enough landmass to grow hemp to do everything it is alleged that it can do.

[DouglasKC]

The pot propaganda is strong in this one...

[DannyTN]

How much hemp did they smoke before they came to this conclusion?

[BiglyCommentary]

Probably fake data that the college kids dummied up but it gave an excuse to grow and maintain a huge number of pot plants on campus.

[Governor Dinwiddie]

Like wow. Like heavy man.

They “cooked” the woody pulp and processed them into carbon nanosheets, which they used to build supercapacitors

—
Sounds very expensive - might end up costing the same or more than lithium, much more.

[marktwain]

What a misleading article.

I read the abstract.

It is not even about a battery. It is about a supercapacitor.

The energy densities are very small. 12 Watt-hours per kg. From the abstract:

Moreover the assembled supercapacitor device yields a maximum energy density of 12 Wh kg–1, which is higher than that of commercially available supercapacitors.

The energy density of lithium-ion batteries are typically 100 - 265 Wh kg–1.

This experimental, laboratory device, has about 4-12% the energy density of existing lithium-ion batteries.

"Hey mon, ya got any more of those "hemp batteries?"

[Army Air Corps]

The problem is that when these batteries catch fire, no one wants to extinguish them.

[Carl Vehse]

Carbon atoms, from various sources such as hemp or other hydrocarbpn waste, can be used to form various pure carbon compounds such as diamond, graphite, and graphene.

A sheet of graphene that is rolled into a cylinder form is usually referred to as a... wait for it... nanotube.

These nanotubes can be used in various ways, some similar to that of graphene, or can be "unzipped" to form graphene sheets.

Interesting. I hope it turns into something.

[E. Pluribus Unum]

And this is the last we will ever hear of it.

[BereanBrain]

somebody was consuming the study materials rather than doing science...

[mosesdapoet]

Nice find ! On my list

Hey Ma, who knew that cannibus sativa would save the world?

Fake news.

What do you feed a battery when it gets the munchies?

[Albion Wilde]

Five minutes later, the car wants its fluids topped off.
