Iviki elisha nebhethri elisha: I-LeydenJar ine-silicon anode namaphesenti angu-170 amabhethri. ikhona

Inkampani yaseDashi i-LeydenJar (ibhodlela le-Leyden yasePoland) yaziqhenya ngokwenza i-silicon anode elungele ukukhiqiza yamaseli e-lithium-ion. Lokhu kuvumela umthamo weseli ukuthi ukhuphuke ngamaphesenti angama-70 uma kuqhathaniswa nezixazululo ezijwayelekile ezinama-graphite anode.

I-silicon esikhundleni se-graphite kuma-anode iyinzuzo enhle kodwa isici esinzima.

Uhlu lokuqukethwe

• I-silicon esikhundleni se-graphite kuma-anode iyinzuzo enhle kodwa isici esinzima.
  • I-LeydenJar: Futhi sazinzisa i-silicon, ha!
  • Inkinga yokuqina isekhona

I-silicon ne-carbon ziyingxenye yeqembu elifanayo lezinto: izakhi ze-carbonaceous. Ikhabhoni esesimweni segraphite isetshenziswa kuma-anode amaseli e-lithium-ion, kodwa sekunesikhathi eside kufunwa indlela yokuyishintsha into eshibhile futhi ethembisayo - i-silicon. Ama-athomu e-silicon enza isakhiwo esixekethile nesinezimbotshana. Futhi uma isakhiwo sinezimbotshana eziningi, isilinganiso esikhulu sobuso nevolumu, izindawo eziningi lapho ama-ion e-lithium angalungiswa khona.

Isikhala esiningi se-lithium ion sisho umthamo we-anode owengeziwe. Okusho ukuthi, umthamo webhethri omkhulu, osebenzisa i-anode enjalo.

Izibalo zethiyori zibonisa lokho i-silicon anode ingagcina izikhathi eziyishumi (izikhathi ezingu-10!) ama-ion e-lithium amaningi kune-graphite anode... Nokho, lokhu kuza ngezindleko: kuyilapho ama-graphite anode ekhula kancane ngesikhathi sokushaja, i-silicon anode eshajwayo ingavuvuka izikhathi eziphindwe kathathu (amaphesenti angu-300)!

Waba yini umphumela? Impahla iyabhidlika, isixhumanisi sisheshe silahlekelwe amandla. Ngamafuphi: ingalahlwa.

I-LeydenJar: Futhi sazinzisa i-silicon, ha!

Kule minyaka eyishumi noma ngaphezulu edlule, kuye kwaba nokwenzeka ukwengeza kancane i-graphite nge-silicon ukuze kubuyiselwe okungenani amaphesenti ambalwa wamandla engeziwe. Izinhlelo ezinjalo zaqiniswa yi-nanostructures ehlukahlukene ukuze umphumela wokukhula kwamanethiwekhi we-silicon ungalimazi amaseli. U-LeydenJar uthi wenze indlela yokusebenzisa ama-anode enziwe ngokuphelele nge-silicon.

Le nkampani ihlole ama-silicon anode kumakhithi atholakalayo kwezohwebo, isibonelo ngama-cathode e-NMC 622. amandla athile 1,35 kWh / lkuyilapho amaseli angu-2170 asetshenziswa ku-Tesla Model 3 / Y enikeza cishe u-0,71 kWh / L. I-LeydenJar ithi ukuminyana kwamandla kungaphezulu ngamaphesenti angama-70, okusho ukuthi ibhethri losayizi othize lingagcina amandla angaphezulu okungamaphesenti angama-70.

Lokhu sikuhumushela ku-Tesla Model 3 Long Range: esikhundleni samakhilomitha angama-450 wangempela, ibanga lendiza lingafinyelela amakhilomitha angama-765 ngenkokhiso eyodwa.... Akukho ukwanda kwebhethri.

Inkinga yokuqina isekhona

Ngeshwa, amaseli asekelwe ku-silicon e-LeydenJar awalungile. Bakwazi ukusinda imijikelezo yokusebenza engaphezu kwe-100 в ukushaja / ukukhipha ngomthamo ongu-0,5C... Izinga lemboni okungenani imijikelezo engu-500, futhi ku-0,5 ° C, ngisho namaseli e-lithium-ion angeyona inkimbinkimbi kakhulu kufanele amelane nemijikelezo engu-800 noma ngaphezulu. Ngakho-ke, inkampani isebenzela ukukhulisa impilo yamaseli.

Inothi elivela kubahleli be-www.elektrowoz.pl: Uma sikhuluma nge-silicon ne-graphite kumaseli e-lithium-ion, sikhuluma ngama-anode. Ngakolunye uhlangothi, uma sikhuluma nge-NMC, i-NCA noma i-LFP, ngezinye izikhathi sisebenzisa inkulumo ethi "ikhemikhali yeseli", sisho ama-cathodes. Iseli iyi-anode, i-cathode, i-electrolyte nezinye izakhi. Ngamunye wabo uthinta amapharamitha.

Inothi 2 evela ku-www.elektrowoz.pl edition: Inqubo yokuvuvukala kwama-silicon anode akufanele ididaniswe nokuvuvukala kwamaseli ezikhwameni. Lesi sakamuva sivuvukala ngenxa yegesi ekhishwe ngaphakathi, engenawo amandla okuphuma ngaphakathi.

Ukuvula isithombe: ukushaya okuthile 😉 (c) LeydenJar. Uma kunikezwe umongo, cishe sibhekisa ku-silicon anode. Kodwa-ke, uma sinake ukuthambile kwezinto (igoba, ingasikwa nge-scalpel), khona-ke sibhekene namanye ama-silicones, ama-polymers asekelwe ku-silicon. Okuthakaselayo kukodwa.

Lokhu kungase kube nentshisekelo kuwe:
