Double carbon battery

[raymon]

Too good to be true:

The energy density is announced to be equivalent to that of lithium-ion, while the weight would be slightly reduced. But it is above all resistance over time that is full of promise. The double carbon battery would not be damaged by being recharged, thanks to an anode and a cathode both made of carbon. In order not to spoil anything, the charge would be 20 times faster. Finally, the Ryden would be 100% recyclable and also cheaper to produce since it does not use any heavy or rare metal.

But it is a Lithium-Ion battery ... These are the matrices at the level of the electrodes which would be in 'carbonized cotton'

hmmmm ....

It doesn't seem like a revolution but a good evolution. If we triple or quadruple the life of a battery, that it heats less ie better efficiency charge discharge, that we no longer use cobalt and other rare metals ... this can make EVs more "profitable "and even give a second life to the battery while stationary, thus lowering the overall cost.

If all this is not simply an announcement effect ...

[Remundo]

ah yes, quadruple this, multiply it tenfold, no longer have any inconvenience, combine all the advantages, and if my aunt had ...

You seem to me very pessimistic, for example they speak of 3000 cycles if we really only get 1500, that will be very good and the same for the other parameters. Currently EVs are almost "interesting" there they squeezed it more surely.

Good lead batteries already have this longevity, or even more ... and LiFePO4 do much better!

Impossible to compare figures of number of cycles without knowing the associated depth of discharge ...

In general by default it is 50%…
