Nws tsis muaj peev xwm xav txog lub neej tsis muaj kev tswj hwm, chaw ntsa ntoos, hu nkauj me nyuam cov khoom ua si, teeb tsom thiab lwm yam khoom siv rau lub roj teeb. Thiab txawm hais tias qhov tseeb tau pib qhov chaw pib siv roj teeb (rechargeable), cov neeg tsis muaj teeb meem tsis tso, vim lawv yooj yim rau kev hikes thiab qhov chaw tsis muaj peev xwm them lawv. Yog li ntawd, muaj ib qho tsim nyog los tsim roj teeb uas tuaj yeem ua haujlwm ntev dua. Yog li muaj cov roj teeb lithium.
Nyob rau hauv tsab xov xwm no, koj yuav kawm tau li cas lub lithium roj teeb, sau npe thiab seb nws yuav tsum tau rov qab.
Ntaus ntawm roj teeb lithium
Lub lithium roj teeb yog tib lub zog fais fab li ntsev, alkaline thiab alkaline, tsuas yog cov feem ntau cov hlau, lithium, siv tsis txhob anode.
Qhov zoo ntawm lithium roj teeb yog raws li nram no:
- muaj ntau yam kub uas kuv tuaj yeem ua haujlwm;
- siab ceev zog;
- ntev lub neej txee (txog li 15 xyoos);
- me me yuag;
- me me tus kheej tawm.
Nyob ntawm cov khoom siv rau cathode, lithium roj teeb yog:
- lithium hlau disulphide;
- lithium-thionyl chloride;
- lithium-fluorocarbon;
- lithium-manganese dioxide;
- lithium-sulfur dioxide;
- lithium iodine;
- lithium-tooj liab oxide.
Nruab nrab ntawm lawv, lawv txawv nyob rau hauv yuav luag tag nrho cov kev khiav hauj lwm cov yam ntxwv: qhov kev txwv ntawm kev khiav hauj lwm muaj peevxwm, kev khiav hauj lwm muaj zog thiab lub zog.
Vim yog lub complexity ntawm cov tsim txoj kev, xws li roj teeb ntau kim.
Cov cim ntawm lithium roj teeb yog tus qauv:
- AAA, AA, C, D - los qhia qhov loj;
- L - siv rau hauv cov qauv tshuaj ntawm lithium;
- R, F - daim ntawv (cylindrical lossis tiaj);
- cov zauv yog lub vojvoog.
Lithium batteries siv ntau tshaj plaws rau cov teev, lub computer thiab cov khoom kho mob, cov khoom siv yees duab, cov cav laij leb, thiab ntsuas cov twj. Rau yooj yim ntawm kev siv, lawv muaj nyob rau hauv ntau cov ntaub ntawv: lub tog raj kheej, ntsiav tshuaj, khawm, squares, lwm yam.
Rechargeable lithium roj teeb
Yog hais tias lub roj teeb uas tsis yog-rechargeable lithium tseem tsis tau nyob rau hauv kev thov, vim nws cov nqi siab, ces roj teeb (roj teeb) - siv tag nrho cov khoom siv hluav taws xob: laptops, telephones, cameras thiab lwm tus.
Muaj 2 yam:
- lithium-ion;
- lithium-polymer.
Zoo ib yam li lithium roj teeb, lub roj teeb kuj muaj kev ua tau zoo, tab sis vim yog tsis muaj kua cov kua roj ntsha, muaj kev nyab xeeb nyob xeeb thiab ua tau txhua yam zoo. Tab sis lawv yog cov neeg rhiab heev thiab ua haujlwm dhau lawm, yog li ntawd, yuav tsum muaj tus nqi them thiab tus limiter hauv qhov ntaus ntawv. Lithium-polymer roj teeb muaj cov roj ntsha lithium-ion, lawv siv cov roj electrolyte. Tab sis lawv tseem tsis tau yooj yim rau kev siv, txij li lub lithium roj teeb yuav tsum tau them nrog ib tug tshwj xeeb charger.
Raws li nrog alkaline thiab roj roj, muaj cov kev cai ntawm kev lag luam thiab lithium, tsuas yog tsis ua raws li cov cai no tuaj yeem ua rau muaj teeb meem loj dua (hluav taws, tawg).
Thaum ua haujlwm nrog cov roj lithium roj teeb, ua raws li cov lus pom zoo:
- cia rau hauv lub xeev uas tau them rau hauv qhov chaw txias txias;
- ua raws li qhov ntsuas kub;
- Txhob siv tas nrho cov dej ntws tawm tas li;
- Tsis txhob raug hluav taws kub, luv luv ntawm nws cov tiv tauj, muaj kev puas tsuaj rau cov vaj tse thiab kua ua kua rau hauv sab hauv;
- Tsis txhob siv cov roj teeb uas tsis tsim rau hom roj teeb.
Tom qab lub roj teeb tau muab nws lub sij hawm, nws tsis pom zoo muab pov tseg nrog txhua yam khoom noj khoom haus, tab sis yuav tsum raug xa mus rau cov ntsiab lus tshwj xeeb rau kev txais kev siv roj teeb kom paub meej ntxiv uas tsis muaj kev cuam tshuam rau ib puag ncig.
