Vhiki nyowani uye bhatiri nyowani: LeydenJar ine silicon anode uye 170 muzana mabhatiri. aripo

Kambani yeDutch LeydenJar (yePolish Leyden bhodhoro) yakazvirumbidza nekugadzira kugadzirwa-yakagadzirira silicon anode yelithium-ion masero. Izvi zvinobvumira kuti sero simba riwedzerwe ne70 muzana zvichienzaniswa neyakajairwa mhinduro ine graphite anodes.

Sirikoni panzvimbo yegraphite mune anodes yakanaka mukana asi chinhu chakaoma.

Tafura yezvinyorwa

• Sirikoni panzvimbo yegraphite mune anodes yakanaka mukana asi chinhu chakaoma.
  • LeydenJar: Uye isu takadzikamisa iyo silicon, ha!
  • Dambudziko resimba rinoramba riripo

Silicon uye kabhoni ndezveboka rimwechete rezvinhu: carbonaceous elements. Carbon iri muchimiro chegirafu inoshandiswa muanode ye lithium-ion masero, asi nzira yakagara ichitsvakwa kuitsiva neyakachipa uye inovimbisa chinhu - silicon. Silicon maatomu anoumba imwe yakasununguka uye ine porous chimiro. Uye iyo yakawanda porous chimiro, iyo yakakura chiyero chepamusoro kusvika kuhuwandu, iyo yakawanda nzvimbo iyo lithium ions inogona kugadziriswa.

Yakawanda nzvimbo yelithium ions inoreva kuwanda kweanode. Ndiko kuti, bhatiri rakakura, rinoshandisa anode yakadaro.

Masvomhu anoratidza izvozvo silicon anode inogona kuchengeta kagumi (ka10!) yakawanda lithium ions pane graphite anode... Nekudaro, izvi zvinouya nemubhadharo: nepo graphite anode ichiwedzera zvishoma panguva yekuchaja, inochaja silicon anode inogona kuzvimba kusvika katatu (300 muzana)!

Zvakaguma nei? Izvo zvinhu zvinoputsika, iyo link inokurumidza kurasikirwa nekugona kwayo. Muchidimbu: inogona kukandwa kure.

LeydenJar: Uye isu takadzikamisa iyo silicon, ha!

Kwemakore gumi kana kupfuura apfuura, zvave zvichigoneka kuwedzera chikamu girafu nesilicon kudzoreredza zvishoma muzana zvesimba rekuwedzera. Masisitimu akadaro akagadziriswa neakasiyana nanostructures kuitira kuti mhedzisiro yekukura kwesilicon network haina kukuvadza maseru. LeydenJar anoti akagadzira nzira yekushandisa anode yakagadzirwa nesilicon.

Iyo kambani yakaedza masilicon anode mumakiti anotengeswa, semuenzaniso neNMC 622 cathodes. chaiyo simba 1,35 kWh / lnepo masero 2170 anoshandiswa muTesla Model 3 / Y achipa akatenderedza 0,71 kWh / L. LeydenJar inoti kuwanda kwesimba kwakakwira makumi manomwe muzana, zvichireva kuti bhatiri reimwe saizi rinogona kuchengeta 70 muzana yakawanda simba.

Isu tinoshandura izvi kuTesla Model 3 Yakareba Range: pachinzvimbo cheiyo chaiyo 450 makiromita, rwendo rwendege runogona kusvika 765 makiromita pamutengo mumwe chete.... Hapana kuwedzera kwebhatiri.

Dambudziko resimba rinoramba riripo

Nehurombo, LeydenJar silicon yakavakirwa maseru haina kunaka. Vakakwanisa kurarama anopfuura 100 kushanda kutenderera в kuchaja / kuburitsa nekugona 0,5C... Iyo indasitiri chiyero inokwana mazana mashanu ma cycles, uye pa 500 ° C, kunyangwe isiri yakanyanya kuomarara lithium-ion maseru anofanirwa kumira mazana masere kana anopfuura ma cycles. Naizvozvo, kambani iri kushanda kuwedzera hupenyu hwemasero.

> Samsung SDI ine lithium-ion bhatiri: nhasi graphite, nekukurumidza silicon, munguva pfupi lithium simbi masero uye huwandu hwe360-420 km muBMW i3.

Cherechedza kubva kune vapepeti ve www.elektrowoz.pl: Kana tichitaura nezvesilicon uye graphite mumasero e-lithium-ion, tiri kutaura nezve anodes. Nekune rimwe divi, kana tichitaura NMC, NCA kana LFP, dzimwe nguva tichishandisa mutsara wekuti "cell chemistry", tinoreva cathodes. Sero is anode, cathode, electrolyte uye zvimwe zvinhu. Chimwe nechimwe chazvo chinokanganisa ma parameters.

Cherechedzo 2 kubva www.elektrowoz.pl edition: Iyo yekuzvimba maitiro esilicon anodes haifanirwe kuvhiringika nekuzvimba kwemaseru mumabhegi. Iyo yekupedzisira inoputika nekuda kwegesi yakabudiswa mukati, iyo isina kukwanisa kupukunyuka kubva mukati.

Kuvhura mufananidzo: kubaya chimwe chinhu 😉 (c) LeydenJar. Tichifunga mamiriro ezvinhu, isu tiri kutaura nezve silicon anode. Zvisinei, kana tikacherechedza kunyorova kwezvinhu (inokotama, inogona kutemwa ne scalpel), saka tiri kutarisana nemamwe silicones, silicon-based polymers. Zvinova zvinokatyamadza pachazvo.
