Sodium-ion bhatiri yekugadzira nheyo

Mabhatiri e-sodium-ion (SIBs kwenguva pfupi) mabhatiri ekuchengetedza simba anogona kudzokororwa ane zvakanakira zvehuremu hwepamusoro, huremu huremu, kugadzirwa kwakaderera, kuzviburitsa, uye mutengo wakaderera. Iyo yakagadziridzwa maSIBs mudziyo unogona kutsiva echinyakare Graphene lithium mabhatiri anosimudzira zvine simba kushandiswa kwesimba revanhu.

Kazhinji kutaura, mutemo wekushanda weSIBs unotevera: panguva yekuchaja / kuburitsa, kuwanda kweNa + pamagetsi eSIBs kunowedzera / kuderera, uye nekushandiswa kwemitoro uye shanduko mumaelectrode awo, kubhadharisa oxidation / kuderedzwa kunozoburitsa mabhondi ehydrogen. . Aya maitiro anopedzwa nemidziyo miviri yakatarisana neye electrochemical cell. Imwe yakatarisana mudziyo ine Na+ electrolyte, uye imwe yakatarisana mudziyo ine electrode fluid.

Kuti usangane nehupamhi hwepamusoro uye huwandu hunodiwa hwezvigadzirwa zvemagetsi, vaongorori vanowanzo shandisa ma curved electrode kuderedza saizi yebhatiri yeSIBs. Kuenzaniswa nedzimwe mhando dzemabhatiri e-lithium-ion, ma electrode akakomberedzwa anogona kutamisa Na+ pakati pemidziyo miviri zvakanyanya. MaSIB anogona zvakare kuvandudzwa kuita nano-copolymer electrodes, iyo inovimbisa huwandu hwepamusoro uye inogara ichigona kuita kwebhatiri panguva yemaitiro chaiwo.

20 zvakanakira nezvayakaipira

mukana:

1. Mabhatiri e-sodium-ion ane simba rakakwirira uye anogona kuchengetedza simba rakawanda, zvichiita kuti zvive nyore kune zvikumbiro zvakakura;

2. MaSIB maduku muhukuru uye akareruka muhuremu, izvo zvinogona kuchengetedza nzvimbo uye uremu;

3. Ane zvakanaka kupisa kuramba uye yakakwirira tembiricha kugadzikana;

4. Diki-discharge rate, yakawanda yakasimba yekuchengetedza simba;

5. MaSIB ane kuchengeteka zviri nani pane mamwe mabhatiri uye haanyanyi kupisa mukati mepolarization yemvura;

6. Iine kugona kudzokorodza kwakanaka uye inogona kushandiswazve kakawanda;

7. MaSIB ane mutengo wakaderera uye anochengetedza mari yezvinhu mukugadzira.

kukanganisa:

1. MaSIB ane mhepo yakaderera pasi pemamiriro ezvinhu akajairika uye haana kukodzera kushandiswa mumashandisirwo akakwirira-voltage;

2. maSIBs anowanzova nepamusoro conductivity, zvichiita kuti mutero wakaderera uye ushande zvakanaka;

3. Kupikisa kwemukati kwakakwirira, uye kubhadharisa uye kuburitsa maitiro kunokonzera kurasikirwa kukuru;

4. Iyo electrode zvinhu hazvina kugadzikana uye zvakaoma kuchengetedza kwenguva yakareba;

5. Mabhatiri dzimwe nguva ane yakakwirira yekutadza mwero pasi pekupisa kwakanyanya uye mamiriro akaoma;

6. Iko kuderedzwa kwesimba reSIBs kunokonzera kurasikirwa kukuru panguva yekutenderera;

7. Hazvisi zvese zvigadzirwa zvemagetsi zvinogona kushandisa sodium-ion mabhatiri. Semuenzaniso, zvimwe midziyo inoda kuchengetedza imwe voltage yekupinza isati yashanda nemazvo.
