Tumen: Peb muaj supercapacitors zoo li lithium-ion roj teeb. Tsuas yog zoo dua
Tuam Tshoj lub tuam txhab Toomen Tshiab Zog thov kom muaj supercapacitors uas muaj lub zog ceev ntawm lithium-ion roj teeb. Tib lub sijhawm, zoo li supercapacitors, lawv muaj peev xwm lees txais thiab tso tawm cov nqi siab dua li cov roj teeb lithium-ion. Tsawg kawg ntawm daim ntawv, qhov no txhim kho kev ua haujlwm ntawm lub tsheb thiab kev them nqi.
Supercapacitors tsis siv roj teeb? Los yog tej zaum kev lag luam?

Lub supercapacitors hauv nqe lus nug tau coj mus rau Tebchaws Europe los ntawm Belgian Eric Verhulst. Thaj, nws tus kheej tsis ntseeg txog lub peev xwm tshaj tawm los ntawm cov chaw tsim khoom, vim tias lawv tau nees nkaum lub sijhawm zoo dua li qhov tsis tau cog lus los ntawm Maxwell. Peb ntxiv tias Maxwell yog ib tus thawj coj hauv kev lag luam supercapacitor thiab tau yuav los ntawm Tesla hauv 2019 (qhov chaw).

Verhulst boasts tias Suav supercapacitors tuaj yeem tiv thaiv kev them nyiaj ntawm 50 C (50x lub peev xwm), thiab ob peb lub hlis tom qab them nyiaj, lawv tseem tuav tus nqi zoo, uas tsis pom tseeb nrog cov supercapacitors. Tsis tas li ntawd, lawv tau sim los ntawm University of Munich, thiab thaum lub sij hawm cov kev ntsuam xyuas no lawv muaj peev xwm tiv taus kub ntawm -50 txog +45 degrees Celsius.
Cov chaw tsim khoom suav hais tias nws tau siv "activated carbon" hauv nws cov supercapacitors, tab sis nws tsis paub meej tias qhov no txhais tau li cas. Lub Belgian tshaj tawm tias Toomen twb tau tsim ib pob ntawv supercapacitor nrog lub zog ceev ntawm 0,973 kWh / L. Qhov no yog ntau dua li cov lithium-ion li niaj hnub, thiab ntau tshaj li cov qauv ntawm cov khoom electrolyte uas Samsung SDI nyuam qhuav piav qhia:

Nws tau tshaj tawm tias qhov zoo tshaj plaws supercapacitors los ntawm Tuam Tshoj cov chaw tsim khoom tau mus txog lub zog ceev ntawm 0,2-0,26 kWh / kg, uas txhais tau hais tias lawv tsis muaj qhov tsis zoo tshaj li niaj hnub Li-ion roj teeb.
Tab sis qhov ntawd tsis yog tag nrho. Lub Belgian sau tseg tias muaj Toomen supercapacitors tsim kom tau txais / tso tawm ntau lub zog ntau dua. Lawv muab lub zog qis dua (0,08-0,1 kWh / kg), tab sis cia them thiab tawm ntawm 10-20 C. Hauv kev sib piv, cov roj teeb uas siv hauv Tesla Model 3 muab lub zog ntom ntom ntawm ntau dua 0,22 kWh / kg (ib roj teeb theem) nrog lub zog them ntawm 3,5 C.
Lwm Hummingbird?
Toomen Tshiab Zog cov lus cog tseg zoo heev ntawm daim ntawv. Cov kev piav qhia tsis tau qhia tias cov supercapacitors ntawm Suav chaw tsim khoom tuaj yeem hloov cov roj teeb, lossis tsawg kawg ntxiv rau lawv. Cov zis hluav taws xob tam sim no tuaj yeem ua kom nrawm dua li 2 vib nas this lossis them los ntawm 500 txog 1 kW..
Qhov teeb meem yog tias peb tsuas yog nrog cov lus cog tseg. Keeb kwm paub xws li "tawg" inventions, uas tau los ua ib tug fake. Ntawm lawv yog cov roj teeb Hummingbird:
