Ngowuphi Umahluko phakathi kwebhetri yeLithium eSolid-State kunye nebhetri yeLithium yeLithium?

Iibhetri eziqinileyo ayizizo zonke i-electrolyte eqinileyo, ezinye zilulwelo (umxube wolwelo kunye nokuqina kuxhomekeke kumlinganiselo wokuxuba).

Ibhetri ye-lithium yelizwe lonke ibhetri ye-lithium eqinile kodwa akukho nanye i-electrode yelizwe lolwelo kunye nezinto ze-electrolyte phantsi kwexesha lobushushu bokusebenza, ngoko ke igama layo elipheleleyo yibhetri ye-electrolyte lithium.

Ibhetri ye-lithium ion yokwenene ine-electrolyte eqinileyo, kodwa kusekho i-electrolyte encinci yolwelo. I-electrolyte ye-semi-solid state ibandakanya isiqingatha se-electrolyte eyomeleleyo, isiqingatha se-electrolyte yolwelo, okanye isiqingatha sebhetri sisimo esiqinileyo, isiqingatha sayo singulwelo. Kusekho ibhetri ye-ion ye-lithium equlethe ubukhulu becala imeko eqinileyo kunye nemeko yolwelo oluncinci.

Ngokuphathelele ibhetri ye-lithium ion yelizwe eliqinileyo ekhaya nakwamanye amazwe, iyaqhubeka idumile. IMelika, iYurophu, iJapan, iKorea neChina zonke zityala imali kuyo ngeenjongo ezahlukeneyo. Umzekelo, iMelika ityala imali kakhulu kwiinkampani ezincinci kunye neziqalo. Kukho iziqalo zempilo ezimbini eMelika, enye yazo yi-S-akit3. Nangona ikwinqanaba lokuqala, umgama wokuqhuba ungafikelela kuma-500km.

IMelika igxile kwitekhnoloji ephazamisayo kwiinkampani ezincinci kunye neziqalo, ngelixa iJapan ithande ukuphanda ibhetri ye-ion ye-lithium ion. Inkampani edume kakhulu eJapan yiToyota, eya kuqonda ukurhweba ngo-2022. Yintoni eveliswa yiToyota ayikho yonke ibhetri ye-lithium ion, kodwa ibhetri ye-lithium ion.

Ibhetri yelizwe eliqinileyo eveliswe yiToyota ine-graphic, i-sulphide electrolyte njengezinto zecathode kunye ne-anode yombane ophezulu. Umthamo webhetri enye yi-15 Ah, kwaye amandla ombane ngama-volts amaninzi. Kuyenzeka ukuphumeza urhwebo ngo-2022.

Ke iJapan ayizinikezeli kwitekhnoloji ephazamisayo, kodwa isebenzisa i-anode yangaphambili kunye ne-cathode kwibhetri ye-lithium ion. IKorea iyafana neJapan, inegraphite cathode kodwa hayi intsimbi yelithium. Ngokwenyani, kunjalo neTshayina. Ngenxa yokuba sele sinomgca omkhulu wemveliso kwibhetri ye-lithium ion, akukho mfuneko yokuqalisa kwakhona zonke kunye.
