Cov Tub Ntxhais Sib Txawv

Kev tsis muaj teeb meem

Qhov zoo yog pom tseeb: Lub thermal khiav tawm kub yog qhov siab (txog 200-250 degree), thiab nws tsis yooj yim rau hluav taws lossis tawg thaum muaj qhov kub siab, lossis extrusion; Txawm hais tias muaj lub luv luv ntawm Circuit Court, nws feem ntau yog qhia li haus luam yeeb ntau dua li qhib cov nplaim taws.

Tsis muaj zog: Lub thermal khiav tawm qhov kub thiab txias (li 150-200 degreggen

Lub neej hluav taws xob zoo li cas tsis muaj cov qauv oxygen (ruaj khov), thiab lub ternary goods muaj cov oxygen ntawm qhov kub kom pab tau kev sib txuas).

Voj voog lub neej

Qhov zoo yog pom tseeb: kev them nyiaj thiab tawm mus ntev tau 2000-3000 zaug ntawm chav sov (seem muaj peev xwm ntau dua li 80%); Qee cov khoom lag luam zoo tau tshaj 5000 zaug (xws li lub zog cia-qib LFP).

Tsis muaj zog: voj voog lub neej 1000-1500 zaug (seem muaj peev xwm ntau dua los yog sib npaug rau 80%); High-Nickel Ternary (xws li NCM811) muaj lub neej luv (txog 800-1000 zaug).

Cov qauv siv lead ua ntawm ternary cov ntaub ntawv yog nquag ua rau ntim nthuav tawm vim tias cov qauv muaj sia thiab kev rho tawm muaj zog dua (cov txiv roj teeb sib txawv).

Lub Zog Ntiab

Qhov tsis zoo: Tib lub zog cell lub zog ceev yog li 150-200 wh / kg; Qeb theem (suav nrog casing, BMS) yog li 100-150 wh / kg.

Qhov zoo yog qhov tseem ceeb: ib lub zog ntawm tes ntom ntom nti 200-300 wh / kg; Txheej Txheem-Qib 150-250 wh / kg (High-Nickel NCM tuaj yeem ncav cuag 300+).

Cov ntaub ntawv ternary tau muaj peev xwm siab dua theoretical muaj peev xwm (piv txwv li lub peev xwm electrode muaj txog li 150-220 mah / g, LFP yog kwv yees li 170 mAh / g) thiab ntau dua ntom ntom.

Them nqi thiab txo qis kev ua tau zoo

Ntau dua (85% -90%), tsis muaj kev ua kom muaj zog ntxiv thaum lub sijhawm siab tam sim no thiab kev tso tawm (haum rau kev ncua ntau zaus thiab rho tawm).

Kev ua tau zoo ntawm LFP yog siab (85% -95%), tab sis nws yog qhov zoo dua li LFP ntawm kev ntsuas tus nqi siab thiab tawm mus saum toj (xws li sab hauv kev tiv taus sab hauv).

Qhov sib txawv me ntsis thiab ob qho tib si tuaj yeem ua tau raws li cov kev xav tau ntawm cov xwm txheej ntau tshaj plaws.

Siab thiab tsawg kub yoog

Kev kub siab kub zoo heev: kev ua tau ruaj khov hauv qab 60 degree, muaj peev xwm qeeb;

Tsawg kub kub shortcomings: muaj peev xwm txo qis rau 70% -80% ntawm -10 degree, thiab tee rau 50% ntawm -20 kev pab cuam (kev pab cuam cua sov (cua sov yuav tsum).

Tsawg qhov kev pab kub zoo: 70% -80% ntawm lub peev xwm tuaj yeem tswj hwm ntawm -20 degree, thiab ntau dua 50% tuaj yeem tswj hwm ntawm -30℃(tsis muaj cua sov ntxiv);

Kev kub siab ntxiv tsis zoo: Muaj peev xwm lwj nrawm dua 40 degree, thiab lub sij hawm ntev kub tau yooj yim coj los rau thermal khiav ceev xwm.

Lub ion conductivity ntawm ternary cov ntaub ntawv yog tsawg dua cuam tshuam los ntawm tsawg kub, thiab ion tsiv teb tsaws ntawm lifepo₄ txo qis ntawm qhov kub tsawg.

Tus nqi

Qhov zoo yog pom tseeb: tus nqi qis tus nqi (tsis muaj cobalt (tsis muaj Cibalt, pheej yig hlau / phosphorus), monomer tus nqi yog 20% -30% qis dua ternary; Tag nrho lub neej voj voog (xam los ntawm tus naj npawb ntawm cov voj voog) yog ntau tshaj 50% qis dua.

Tus nqi siab: cobalt (accounting rau 40% -50% ntawm cov nqi siv nyob rau hauv 2023 yuav yog hais txog RMB 300,000 ib tuj, ntau dua 1,000 zaus uas hlau); Lub neej muaj sia nyob lub neej.

Cov ntaub ntawv muaj hluav taws xob zoo rau 60% ntawm lub roj teeb nqi. Cov ntaub ntawv ternary nyob rau ntawm cov hlau siab, thaum LFP cov ntaub ntawv yog pheej yig thiab ruaj khov.

Lwm Cov Nta

Tsis muaj qhov cim xeeb, tuaj yeem cuam tshuam nrog 20% ntxiv tsis cuam tshuam rau lub neej); Tsis tshua muaj ntim ntom ntom (loj dua ntim ntawm tib lub peev xwm).

Tsis muaj qhov cim xeeb, sib zog nqus tawm (<20%) has a greater impact on life; high volume density (smaller volume at the same capacity).
