Hupfumi uye iwe neni tinoda mamwe masimba ekuchengetedza epamusoro. Izvi zviri kufambiswa nenzvimbo dzakaita sekutakura magetsi ega ega, simba regirini, magetsi anopfekeka nezvimwe zvakawanda. Kufanana nezvose zviri kudiwa zvakanyanya, mabhatiri anovimbisa anova nyaya yekufungidzira, izvo zvinopa vimbiso dzakawanda, pakati pazvo zvakaoma kuwana maparera chaiwo. Saka maFrench akazvidhonza. Vachakwanisa here?
Kambani yeFrance inogadzira supercapacitors uye mabhatiri Nawa Technologies kumabhatiri, kabhoni nanotube electrode itsva, iyo inobvumira vagadziri kugadzira mabhatiri ekudhonza ane hunhu huri nani. Kambani inovimbisa kuwedzera simba rebhatiri kakapetwa kagumi, simba chairo rinosvika katatu, kutenderera kwehupenyu kusvika kashanu uye kuderedza nguva yekuchaja kusvika kumaminetsi pane maawa.
Mashoko aya anonongedzera kubhindauko mukugadzirwa kwebhatiri. Uye izvi zvinonyanya kufadza nekuti mugadziri anovimbisa kupa tekinoroji yakagadzirwa-yakagadzirwa yekugadzira mabhatiri maererano neresipi yake mukati memwedzi gumi nemiviri.
Saka vaFrench vanopa chii? Uye vanopa zano rekusiya tekinoroji yechinyakare yekugadzirwa kwebhatiri electrodes (anodes uye cathodes). Nhasi, ma electrode anogadzirwa kubva musanganiswa wehupfu yakanyungudutswa mumvura kana zvakakosha zvinonyungudutsa. Musanganiswa unoshandiswa kune foil uye wobva waoma. Iyi tekinoroji yakazara nehuterogeneity yakakosha mukuumbwa kwezvinhu zvinoshanda zvema electrode uye nekufamba kwenguva zvinotungamira mukuparara kwayo. Kambani yeNawa inofunga kusiya hupfu nemhinduro uye kurima kabhoni nanotubes pafoiri sehwaro (sponge) yezvinhu zvinoshanda (lithium).
Iyo tekinoroji yakatsanangurwa nekambani inoita kuti zvikwanise kukura kusvika ku2 bhiriyoni kabhoni nanotubes pane yega cm100 yefoil. Uyezve, tekinoroji yeNawa inoita kuti zvikwanise kukura zvakamira zvakadzika nanotubes (perpendicular to the base), iyo inopfupisa nzira yelithium ions kubva kune imwe electrode kuenda kune imwe makumi enguva. Izvi zvinoreva kuti iyo electrode zvinhu inokwanisa kupomba yakawanda yemagetsi ikozvino kuburikidza pachayo, uye yakarongedzerwa chimiro cheyakaenzana yakatarisana nanotubes inochengetedza nzvimbo mukati uye huremu hwebhatiri rese, izvo zvinozoita kuti kuwedzera kwebhatiri kugona.
Zvakare, sezvo maelectrode anosvika makumi maviri neshanu muzana emutengo wemabhatiri emazuva ano, kugadzirwa kweNawa kunovimbisa kudzikisa mutengo wavo. Tekinoroji yekugadzirwa kweramangwana ndeyekuti machubhu anozorimwa pafoiri mita imwe yakafara uchishandisa roll (rolling) nzira. Sezvineiwo, tekinoroji iyi yakagadziridzwa nekambani kuburitsa chizvarwa chitsva chevaridzi supercapacitors, asi inovimbisa kuwana zvakare application mukugadzirwa kwe lithium mabhatiri.
