Ibhetri yeLithium polymer

Ibhetri ye-lithium polymer

I-Lithium-ion kunye neebhetri ze-polymer ze-lithium ziintlobo zebhetri ezinokutshajwa kwakhona ezine-lithium njengento esebenzayo ye-electrochemical. Iibhetri ze-Li-ion zezinye zezona ntlobo zeeseli zidumileyo kwihlabathi zombane ophathwayo. Kwiminyaka yakutshanje, imveliso enkulu yezi seli ikhuthazwe kukufuna iplagi-in izithuthi zombane kunye negridi yokugcina izicelo.

Iibhetri zeLithium-ion yayizezi bhetri zokuqala ezikwaziyo ukutshajwa kwakhona kurhwebo kuzo zonke iindidi, nto leyo eyenza ukuba zaziwe. Balawula imakethi ye-elektroniki ephathekayo ngenxa yoxinano lwamandla aphezulu, ukutshaja ngokukhawuleza kunye nokungabikho kwememori. Imveliso ephezulu yangoku yezixhobo zamandla ezisekelwe kwi-lithium-ion zenza ukuba zilungele izicelo ezifana nemithi, ukugaya kunye nokugaya.

Iibhetri ze-lithium zepolymer zibhityile, iibhetri ezisicaba ezibandakanya i-anode edibeneyo kunye nemathiriyeli ye-cathode ezahlulwe yi-polymer electrolyte. I-polymer electrolyte inokongeza ukuguquguquka kwibhetri, okwenza kube lula ukupakisha kwiindawo ezincinci kuneebhetri ze-lithium-ion.

Uhlobo oluqhelekileyo lwebhetri ye-lithium polymer isebenzisa i-lithium ion anode kunye ne-electrolyte ephilayo, kunye ne-electrode engalunganga eyenziwe ngekhabhoni kunye ne-anode composite cathode material. Oku kwaziwa njenge-lithium polymer primary cell.

Indlela eqhelekileyo yebhetri ye-lithium-ion isebenzisa i-lithium metal anode, i-carbon black cathode kunye ne-electrolyte ephilayo. I-electrolyte sisisombululo se-solvent ye-organic, ityuwa ye-lithium kunye ne-polyvinylidene fluoride. I-anode inokwakhiwa ngekhabhoni okanye igraphite, i-cathode yenziwa ngokuqhelekileyo kwi-manganese dioxide.

Zombini ezi ntlobo zeebhetri zisebenza kakuhle kumaqondo obushushu aphantsi kodwa iibhetri ze-lithium zepolymer zinomthamo ophakamileyo wombane kunomlinganiselo ofanayo weseli ye-lithium-ion. Oku kuvumela ukupakishwa okuncinci kunye nobunzima beebhetri ezikhaphukhaphu kwizicelo ze-elektroniki eziphathwayo zisebenzisa i-3.3 volts okanye ngaphantsi, njenge-eReaders ezininzi kunye nee-smartphones.

I-voltage yegama leeseli ze-lithium-ion yi-3.6 volts, kanti iibhetri ze-lithium ze-polymer zifumaneka kwi-1.5 V ukuya kwi-20 V. unxibelelwano olukhulu phakathi kwe-anode.
