Taw qhia: Lub Microscopic Miracle ntawm Zog Hloov
Nyob rau hauv tam sim no lub xov tooj smartphone illuminates, thaum lub suab nrov ntawm lub tsheb hluav taws xob lub cav pib, thiab raws li txoj hauv kev ntawm satellite tho los ntawm huab cua, roj teeb - raws li cov khoom siv tseem ceeb rau kev hloov hluav taws xob thiab khaws cia - tau hloov pauv tib neeg kev vam meej los ntawm trillions ntawm ionic migrations ib ob. Txij li thaum yug los ntawm Volta pawg hauv xyoo 1800 mus rau kev lag luam kev lag luam ntawm lithium hlau manganese phosphate roj teeb hauv xyoo 2025, roj teeb thev naus laus zis tau dhau los ua peb qhov kev hloov pauv: los ntawm tshuaj lom neeg mus rau hluav taws xob, los ntawm ib zaug - siv los rov ua dua, thiab los ntawm kev sim mus rau industrialization. Qhov no ob -xyoo pua- ntev evolution ntawm lub zog tsis yog tsuas yog propels trillion-$ kev lag luam xws li cov neeg siv khoom hluav taws xob thiab lub zog tshiab tsheb tab sis kuj ua hauj lwm raws li lub linchpin rau kev ua tiav lub ntiaj teb no carbon neutrality cov hom phiaj.
1.1 Lub hauv paus ntsiab lus ntawm Electrochemical Principles
Lub luag haujlwm tseem ceeb ntawm cov roj teeb yog nyob ntawm kev hloov hluav taws xob thaum lub sijhawm redox tshwm sim. Siv lithium- roj teeb lithium ua piv txwv, thaum lub sijhawm them nyiaj, lithium ions deintercalate los ntawm cov khoom siv cathode (xws li, LiCoO₂), tsiv los ntawm electrolyte mus rau anode (graphite), thaum electrons tsim hluav taws xob tam sim no los ntawm sab nraud Circuit Court; cov txheej txheem tso tawm tshwm sim nyob rau hauv thim rov qab. Qhov no "pob zeb- lub rooj zaum" ion tsiv teb tsaws mechanism ua rau cov lithium- ion roj teeb kom ua tiav qhov kev them nqi - tawm kev ua haujlwm txog li 95%.
Nickel{0}}hlau hydride roj teeb siv nickel hydroxide cathodes thiab hydrogen cia alloy anodes, nrog KOH kua raws li cov electrolyte. Lawv qhov tshwj xeeb yog nyob rau hauv hydrogen cia alloy lub peev xwm los nqus hydrogen sib npaug rau ntau pua lub sij hawm nws tus kheej ntim, muab cov roj teeb no lub zog ntom ntom 2-3 npaug ntawm cov hlau lead-acid roj teeb. Lub caij no, lead-acid roj teeb, los ntawm cov tshuaj tiv thaiv rov qab los ntawm cov hlau lead- lead dioxide-sulfuric acid system, tuav 65% kev lag luam sib koom hauv cov roj teeb pib txawm tias lawv qis zog, ua tsaug rau lawv cov nqi zoo.
