Qhov zoo thiab qhov tsis zoo ntawm ternary lithium roj teeb
Lub roj teeb ternary lithium yog qhov sib npaug ntawm lub peev xwm thiab kev nyab xeeb, thiab yog lub roj teeb uas muaj kev ua tau zoo heev. Lub luag haujlwm tseem ceeb thiab qhov zoo thiab qhov tsis zoo ntawm peb lub ntsiab lus hlau yog raws li hauv qab no:
Co3 ntxiv: Txo cov cation sib xyaw ua haujlwm, txhim kho cov txheej txheem txheej txheem ntawm cov khoom, txo cov nqi impedance, txhim kho cov hluav taws xob conductivity, thiab txhim kho lub voj voog thiab kev ua haujlwm zoo.
Ni2 ntxiv: Nws tuaj yeem txhim kho lub peev xwm ntawm cov khoom siv (ua kom lub zog ntim ntawm cov khoom siv), thiab vim yog lub vojvoog zoo sib xws ntawm Li thiab Ni, ntau dhau Ni kuj tseem yuav ua rau qhov tshwm sim dislocation nrog Li ua rau kev sib xyaw ua ke ntawm lithium thiab npib tsib xee, thiab cov concentration ntawm nickel ions hauv txheej lithium Qhov loj dua, qhov nyuaj dua rau lithium kom deintercalated nyob rau hauv cov txheej txheem txheej, ua rau tsis zoo electrochemical kev ua tau zoo.
Mn4 ntxiv: Tsis tsuas yog tuaj yeem txo cov nqi khoom, tab sis kuj tuaj yeem txhim kho kev nyab xeeb thiab ruaj khov ntawm cov khoom. Tab sis cov ntsiab lus Mn siab dhau lawm yuav yooj yim tshwm sim spinel theem thiab rhuav tshem cov txheej txheem, txo lub peev xwm thiab txo lub voj voog.
High energy density is the biggest advantage of ternary lithium batteries, and voltage platform is an important indicator of battery energy density, which determines the basic performance and cost of the battery. The higher the voltage platform, the greater the specific capacity, so the same volume, weight, even the same An hour's battery has a longer battery life than a ternary material lithium battery with a higher voltage platform. The discharge voltage platform of single ternary lithium battery is as high as 3.7V, lithium iron phosphate is 3.2V, and lithium titanate is only 2.3V. Therefore, from the perspective of energy density, ternary lithium battery is better than lithium iron phosphate, lithium manganate or lithium iron phosphate. Lithium titanate has absolute advantages.
Kev nyab xeeb tsis zoo thiab lub neej voj voog luv luv yog qhov tsis txaus ntseeg ntawm ternary lithium roj teeb, tshwj xeeb tshaj yog kev nyab xeeb kev ua haujlwm, uas yog ib qho tseem ceeb txwv nws qhov loj -scale configuration thiab loj -scale integrated applications. Ntau qhov kev ntsuas tiag tiag qhia tau tias nws nyuaj rau lub roj teeb ternary nrog lub peev xwm loj kom dhau qhov kev ntsuas kev nyab xeeb xws li acupuncture thiab overcharge, uas yog vim li cas ntau manganese feem ntau nkag mus rau hauv loj - roj teeb muaj peev xwm, lossis txawm tias sib xyaw nrog lithium manganate. Lub neej voj voog ntawm 500 zaug yog nyob rau nruab nrab thiab qis ntawm cov roj teeb lithium, yog li daim ntawv thov tseem ceeb ntawm ternary lithium roj teeb yog 3C digital thiab lwm yam khoom siv hluav taws xob.
