Lithium roj teeb - Cov yam ntxwv thiab daim ntawv thov

Lithium roj teeb yog tus phooj ywg environmentally, zog npaum, tau khiav lag luam yog tsis muaj recharging rau ib ntev lub sij hawm, yog operable thaum uas tsis muaj kub. Txij li thaum lawv yog cov heev zog intensive, thiab nws yog ib pab distinguishes lawv los ntawm lwm yam xws li pab kiag li lawm, lawv cov khoom yog lossi ua. Lawv yog cov muaj nyob rau hauv cylindrical thiab prismatic. Lawv yog siv nyob rau hauv laptops, xovtooj ntawm tes thiab lwm yam portable pab kiag li lawm. Lawv khiav hauj lwm voltage yog hais txog plaub volts. Lawv khiav lag luam nyob rau hauv lub kub ntau los ntawm -20 mus + 60 ° C. Twb, muaj nyob ua ib ke lithium roj teeb uas yuav khiav lag luam ntawm ib tug kub ntawm -40 ° C. Tsis tas li ntawd, muaj hauj lwm nyob rau hauv lub ntxiv extension kub ntau. Lawv tus kheej-paug nyob rau hauv thawj lub hlis ntawm 4-6%, ces qhov no daim duab yog txo thiab lub xyoo lawv poob mus rau nees nkaum feem pua ntawm cov muaj peev xwm. Cov yam ntxwv ho zoo dua cov npib tsib xee-cadmium embodiment. Lawv muaj peev xwm nyob ntev li ntawm 500 mus rau 1000 mus, tab sis lawv tus naj npawb nyob rau ntawm tus nqi ntawm cov kev txwv ntawm cov coupons qhov voltage.

Lithium roj teeb loj AA ntaub ntawv rau tej khoom siv uas muaj ib tug tshwj xeeb qhov kev qhov luaj li cas AA roj teeb. Yog lithium-polymer thiab lithium-ion roj teeb. Cov yav tas los yog ntau muaj kev ruaj ntseg, muaj me me qhov ntev thiab yuav ua tau yam zoo, kom lawv tsis txhob muaj nyob rau hauv lawv cov muaj pes tsawg leeg ntawm ib tug kua ntsha. Housing rau lawv yog ua los ntawm ib tug metallized polymer. Thiab tam sim no feem ntau ntawm cov neeg sawv cev ntawm cov roj teeb nyob rau hauv lub qhov muag ntawm no xyov cov kev taw qhia nrog Helium ntsha. Ib tug disadvantage yog cov rhiab heev rau tus nqi hloov lwm lub tsev, vim ib qho kev nce ntawm cov paug tam sim no yog txo kev khiav hauj lwm voltage. Khaws ntaus ntawv no yog yuav nyob rau hauv chav tsev kub, nrog ib tug tag nrho xwb, thiab ib xyoos ib zaug koj yuav tsum tau ua tsub rau koj. Vim hais tias yog hais tias koj tsis yog, tej zaum nws yuav overdischarge. Cov tsis muaj peev xwm thaum lub sij hawm cia tshwm sim vim cov tshuaj tiv thaiv ntawm lub ntsha nrog lub electrodes. Nyob rau hauv cia li ib tug ob peb lub hlis ntawm cia, lub roj teeb voltage yuav tsum tau significantly txo raws li ib tug tshwm sim ntawm lub charger yuav tsis them nws.

them

Lithium roj teeb yuav tau them chiv ntawm qhov tam sim no mus txog rau thaum ib tug voltage ntawm 4.2 V thiab ntxiv ntawm qhov voltage. Lawv muaj ib tug uas tsis muaj kuj mus overdischarge. Qhov no yuav tsub lub kub nyob rau hauv lub vaj tse nyob. Thiab nws muaj peev xwm tsim txia. Yog li ntawd, lawv yuav tsum tau kev ce mus rau theem pom zoo los ntawm hauv phau ntawv. Heev dejnum nce nyob rau hauv them voltage, yog li nws yog tau txo ntaus kev pab.

cai ua hauj lwm

Lithium roj teeb muaj ib tug kev pab cuam lub neej ntawm 2-3 xyoo. Thiab nws tsis yog nyob ntawm seb yuav ua li cas kwm rau kev siv lawv. Lawv tsis muaj ntev yuav tsum tau muab cia rau qhov chaw, thiab yog tsim rau lub lag luam nruam.

Lawv muaj ib tug tshwj xeeb kev tiv thaiv tiv thaiv overcharge thiab sib sib zog nqus paug, ces lawv yuav nyob twj ywm nyob rau hauv lub charger thiab switched thaum lub sij hawm txhua lub sij hawm tus txheej txheem.

Yog hais tias lub roj teeb yuav tsum tau khaws cia rau 1 lub hlis, ces nws yuav tsum tau tag nrho them. cia kub yuav tsum nyob nruab nrab ntawm + 5 ° C rau + 20 ° C. Yog hais tias nws yog muab cia rau hauv ib tug tawm lub xeev, ces ob lub hlis tom qab, nws ua tsis.

Ntaus zoo tsis yuav nyob ib kub hauv qab no -10 ° C, raws li qhov no zoo heev thiaj li lub sij hawm ntawm lub apparatus ua hauj lwm rau nws. Thaum ib tug kub hauv qab no + 5 ° C nws yuav tsis tau them tag. Thiab nyob rau ib kub saum toj no +40 ° roj teeb heev sai sai tawm.
