Nkag siab txog Kev Tsim Khoom Yam ntxwv ntawm Lithium Battery

Lithium roj teeb yog ib hom roj teeb uas siv lithium hlau lossis lithium alloy ua cov ntaub ntawv zoo / tsis zoo thiab siv cov tshuaj tsis muaj dej electrolyte. Lub roj teeb lithium muaj qhov zoo ntawm qhov tsis tshua muaj tus kheej tawm tus nqi thiab qhov hluav taws xob qis qis, yog li cov pacemaker implanted hauv tib neeg lub cev tuaj yeem ua haujlwm tau ntev yam tsis tau them rov qab. Lub nominal voltage ntawm lithium roj teeb feem ntau yog siab tshaj 3.0V, uas yog haum rau integrated circuit fais fab mov.
Manganese dioxide roj teeb tau dav siv hauv tshuab xam zauv, cov koob yees duab digital thiab saib. Txhawm rau txhim kho cov haujlwm zoo dua qub, tib neeg tau kawm ntau yam ntaub ntawv thiab tsim cov khoom uas tsis tau muaj dua. Nrog txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, lithium roj teeb tau dhau los ua lub ntsiab lus tseem ceeb. Cov roj teeb lithium tuaj yeem muab faib ua ob hom: lithium hlau roj teeb thiab lithium ion roj teeb.
Lub roj teeb lithium-ion tuaj yeem rov ua dua, thiab nws txoj kev nyab xeeb, lub peev xwm tshwj xeeb, tus nqi tso tawm tus kheej thiab tus nqi ua haujlwm zoo dua li cov roj teeb lithium-ion. Vim muaj kev txwv ntawm nws tus kheej high-tech yuav tsum, tsuas yog ob peb lub teb chaws cov tuam txhab tsim cov lithium hlau roj teeb no. Kev khiav hauj lwm hauv paus ntsiab lus ntawm lithium roj teeb: lithium roj teeb feem ntau siv manganese dioxide raws li cov khoom zoo, lithium hlau los yog nws cov hlau alloy ua cov khoom tsis zoo thiab cov tshuaj tsis muaj dej electrolyte.
Cov tshuaj tiv thaiv tawm: Li MnO2=LiMnO2 lithium roj teeb: lithium ion roj teeb feem ntau siv lithium alloy hlau oxide raws li cov khoom zoo, graphite ua cov khoom tsis zoo, thiab tsis muaj dej electrolyte. Cov tshuaj tiv thaiv ntawm cov electrode raug them yog LiCoO2=Li (1-x) CoO2 x Li xe - (electron).
