Is this the big bat­tery break­through?

Is this the elec­tric car break­through we have been wait­ing for?

A Ja­panese com­pany has de­vel­oped a new bat­tery that charges 20 times faster than a lithium ion bat­tery – cur­rently the best pro­duc­tion bat­tery tech­nol­ogy around – and with the same charge den­sity as the best lithium ion units.

On top of that it doesn’t use any rare earth metals such as lithium, cobalt, or man­ganese – in fact it uses no metals at all, in­stead re­ly­ing on car­bon, one of the main­stays of the planet, as its base.

What’s more, the Ja­panese com­pany, Power Ja­pan Plus, is work­ing on a way to make the bat­tery ma­te­ri­als from or­ganic ma­te­rial, which will make it to­tally sus­tain­able.

And, says the com­pany, the whole process is cheaper, and the bat­ter­ies don’t get hot like lithium ion bat­ter­ies can – mean­ing elec­tric cars won’t need costly cool­ing sys­tems, and also mak­ing them much safer in oper­a­tion. And the bat­tery can take al­most dou­ble the num­ber of recharges as a lithium ion bat­tery.

Put into terms we can all un­der­stand, it means a Nis­san Leaf could be recharged in 12 min­utes in­stead of the cur­rent four to five hours. At a recharg­ing sta­tion, this means it would recharge faster than you could drink a cup of cof­fee or use a toi­let!

And an­other sim­pler ben­e­fit – the price of elec­tric cars would come down!

Called the Ry­den dual car­bon bat­tery, it makes use of a com­pletely unique chem­istry, with both the an­ode and the cath­ode made of sim­ple car­bon.

The dual car­bon de­sign used in the bat­tery, com­bined with an or­ganic elec­trolyte, al­lows for a unique cur­rent flow within the bat­tery. Pos­i­tively charged lithium ions flow to the an­ode and the neg­a­tively charged anions flow to the cath­ode. This short­ens the dis­tance of cur­rent flow within the bat­tery, al­low­ing for the faster charge and dis­charge.

Power Ja­pan Plus has filed one patent and is pre­par­ing to file three more on the dual car­bon bat­tery.

The bat­ter­ies can fit into a stan­dard 18650 cell (the one used in lap­tops and elec­tric cars), re­quir­ing no sig­nif­i­cant change to ex­ist­ing man­u­fac­tur­ing lines.

And it would be more pow­er­ful than other bat­ter­ies, op­er­at­ing at over four volts.

The bat­tery would also be highly sus­tain­able, as it is fully re­cy­clable. Power Ja­pan is plan­ning to pro­duce the bat­tery us­ing an or­ganic car­bon com­plex, de­vel­oped in-house from or­ganic cot­ton, to ob­tain a greater con­trol over the size of the car­bon crys­tals in its elec­trodes.

Power Ja­pan is plan­ning to start pro­duc­tion of 18650 dual car­bon cells later this year for spe­cialty ap­pli­ca­tions such as med­i­cal de­vices and satel­lites, and plan to li­cence the tech­nol­ogy to other com­pa­nies for use in elec­tric ve­hi­cles.
