Iibhetri zeLithiumziye zatsala ingqalelo yehlabathi zaza zafumana neMbasa yeNobel edumileyo ngenxa yezicelo zazo ezisebenzayo, ezibe nefuthe elikhulu kuphuhliso lweebhetri nakwimbali yoluntu. Ngoko ke, kutheni iibhetri ze-lithium zifumana ingqalelo engaka ehlabathini zaze zaphumelela neMbasa yeNobel?
Isitshixo sokuqonda ukubaluleka kweebhetri ze-lithium sikwiimpawu zazo ezizodwa kunye nempembelelo yotshintsho ezibe nayo kubuchwepheshe nakuluntu. Ngokungafaniyo neebhetri zemveli, ezixhomekeke kwiimpendulo zeekhemikhali ezibandakanya iintsimbi ezinzima ezifana ne-lead okanye i-cadmium, iibhetri ze-lithium zisebenzisa ii-ion ze-lithium ukugcina nokukhupha amandla. Olu yilo lubonelela ngeenzuzo ezininzi, kubandakanya uxinano lwamandla aphezulu, ubomi obude, kunye nokukwazi ukutshaja ngokukhawuleza, okwenza zibe lukhetho olufanelekileyo kwiintlobo ngeentlobo zezicelo.
Isizathu sokuba iibhetri ze-lithium zidume
Esinye sezizathu eziphambili zokuthandwa nokuthandwa ngabantu abaninziiibhetri ze-lithiumyindima yabo ekwenzeni ukuba izixhobo ze-elektroniki eziphathwayo zisasazeke. Ukufika kwee-smartphones, iitablets, kunye nezinye izixhobo eziphathwayo kutshintshe unxibelelwano, ulonwabo, kunye nemveliso, kwaye iibhetri ze-lithium zibe negalelo elikhulu ekunikezeni amandla ezi zixhobo. Uyilo lwazo olukhaphukhaphu noluncinci, kunye nokukwazi kwazo ukunika amandla athembekileyo nahlala ixesha elide, zenze ukuba zibe yeyona nto ibalulekileyo kwixesha lanamhlanje ledijithali.
Ngaphezu koko, ukunyuka kwezithuthi zombane (ii-EV) kuye kwaqhubela phambili ukugqama kweebhetri ze-lithium. Njengoko ihlabathi lizama ukutshintsha ukusuka kumafutha efosili kunye nokunciphisa ukukhutshwa kwegesi ebangela ubushushu, ii-EV ziye zavela njengendlela ethembisayo kunezithuthi zemveli zokutsha kwangaphakathi. Eyona nto iphambili kwimpumelelo yee-EV ziibhetri ze-lithium ezisebenzayo kakhulu ezinokugcina nokuhambisa amandla amaninzi afunekayo ukuqhuba kumgama omde. Uphuhliso lwetekhnoloji yebhetri ye-lithium-ion ephucukileyo ibe yimpumelelo ebangela ukukhula ngokukhawuleza kwemarike yezithuthi zombane, itsala ingqalelo ebalulekileyo kubatyali-mali, abenzi bomgaqo-nkqubo, kunye noluntu.
Iibhetri ze-lithium ezizinzileyo
Ukongeza kwizicelo zazo kwii-elektroniki zabathengi kunye nothutho, iibhetri ze-lithium zikwadlale indima ebalulekileyo ekudityanisweni kwemithombo yamandla avuselelekayo, njengamandla elanga nawomoya, kwigridi yombane. Iinkqubo zokugcina amandla ezisekelwe kubuchwepheshe be-lithium-ion zenze ukubamba kunye nokusetyenziswa kakuhle kwamandla avuselelekayo okwethutyana, zinceda ukuzinzisa igridi kunye nokunciphisa ukuxhomekeka ekuvelisweni kwamandla asekelwe kwi-fossil fuel. Eli galelo ekuguqukeleni kwiziseko zamandla ezizinzileyo nezizinzileyo liye laphakamisa ngakumbi imeko yeiibhetri ze-lithiumkwiqonga lehlabathi.
Ukuqatshelwa kweebhetri ze-lithium ngeMbasa yeNobel kwiKhemistri ngo-2019 kugxininise impembelelo enkulu yale teknoloji kwihlabathi liphela. Eli bhaso linikezelwe kuJohn B. Goodenough, M. Stanley Whittingham, kunye no-Akira Yoshino ngomsebenzi wabo wokuqala ekuphuhlisweni kweebhetri ze-lithium-ion, bevuma igalelo labo ekuphuculeni iteknoloji yokugcina amandla. IKomiti yeNobel igxininise ukubaluleka kweebhetri ze-lithium ekujongeni imingeni yotshintsho lwemozulu kunye nokwenza kube lula ukutshintsha ukuya kwikamva lamandla elizinzileyo.
Ikamva leebhetri ze-lithium
Ukujonga phambili, ingqalelo kunye nembeko ezifunyenwe nguiibhetri ze-lithiumkusenokwenzeka ukuba ziqhubeke njengoko abaphandi kunye nabathathi-nxaxheba kushishino bezama ukuphucula ngakumbi ukusebenza kwabo, ukhuseleko, kunye nokuzinza kokusingqongileyo. Imizamo eqhubekayo yokwandisa uxinano lwamandla, ukunciphisa iindleko, kunye nokuphucula iinkqubo zokuphinda kusetyenziswe izinto ezintsha iya kuba yinto ebalulekileyo ekuqinisekiseni ukufaneleka okuqhubekayo kunye nempembelelo yeebhetri ze-lithium kwimeko yetekhnoloji eguquka ngokukhawuleza.
Ukuqukumbela, ingqalelo kunye nokuqatshelwa okufunyenwe ziibhetri ze-lithium kuvela kwindima yazo ebalulekileyo ekunikezeni amandla kwinguqu yedijithali, ukuqhuba umbane kwezothutho, kunye nokwenza kube lula ukuhlanganiswa kwamandla ahlaziyekayo. Ibhaso likaNobel elinikwe oovulindlela betekhnoloji yebhetri ye-lithium lisebenza njengobungqina bempembelelo enkulu yale ntsha kwihlabathi liphela. Njengoko uluntu luqhubeka nokwamkela amandla acocekileyo kunye netekhnoloji ephucukileyo, iibhetri ze-lithium zikulungele ukuhlala ziphambili kwingqwalasela yehlabathi kunye noyilo olutsha, zibumba ikamva lokugcina amandla kunye nokuzinza.
