Ukuqonda kokuqala kwamabhethri e-lithium
Siyakwamukela kubhulogi esemthethweni ye-Heltec Energy! Amabhethri e-lithium-ion abe yingxenye ebalulekile yokuphila kwethu kwansuku zonke, anika amandla amadivayisi esithembele kuwo, njengama-smartphone namalaptop, ngisho nezimoto. I-prototype yebhethri yasungulwa ngasekupheleni kwekhulu le-18, futhi sekuyiminyaka engaphezu kwamakhulu amabili kusukela ngaleso sikhathi. Amabhethri e-lithium-ion angenye yezinhlobo ezintsha zamabhethri eziye zazalwa ngesikhathi sokuthuthukiswa kwebhethri.
Amabhethri ahlukaniswe amabhethri omile angasetshenziswa kanye kuphela, "amabhethri ayinhloko", namabhethri angashajwa futhi asetshenziswe izikhathi eziningi, "amabhethri esibili". Amabhethri e-lithium-ion amabhethri esibili angashajwa kabusha. Uma kuqhathaniswa nezinye izinhlobo zamabhethri, amabhethri e-lithium-ion ahlukile ngosayizi wawo ohlangene kanye nezakhiwo ezingasindi, okuwenza alungele izinto zikagesi eziphathwayo. Ngaphezu kwalokho, bayakwazi ukugcina amandla amaningi kagesi, okubenza babe umthombo wamandla osebenza kahle.
Indlela amabhethri e-lithium-ion awenza ngayo ugesi
Umgomo oyisisekelo wokusebenza wamabhethri uyafana, ohlanganisa i-electrode ephozithivu (i-cathode), i-electrode engeyinhle (i-electrode engeyiyo), kanye ne-electrolyte. Ngaphakathi kwebhethri, i-electrolyte ivumela ama-ion ukuba adlule, kuyilapho ama-electron egeleza esuka ku-electrode eyinegethivu eya ku-electrode ephozithivu, ngaleyo ndlela ekhiqiza amandla kagesi. Kumabhethri esibili, njengamabhethri e-lithium-ion, angagcina ama-electron ku-electrode engalungile kusengaphambili ngokushaja, futhi lapho ibhethri likhishwa, lawa ma-electron agelezela ku-electrode ephozithivu, ngaleyo ndlela akhiqize ugesi.
Okulandelayo, ake sibheke izici nezinzuzo zamabhethri e-lithium-ion. Isizathu sokuthi kungani amabhethri e-lithium-ion agqama phakathi kwamabhethri amaningi kungenxa yesakhiwo sawo esiyingqayizivele nokukhetha kwawo okubalulekile. Okokuqala, amabhethri e-lithium-ion asebenzisa izinhlanganisela zensimbi ezine-lithium ku-electrode enhle nekhabhoni (njenge-graphite) ekwazi ukumunca futhi igcine i-lithium ku-electrode engalungile. Lo mklamo uvumela amabhethri e-lithium-ion ukuthi akhiqize ugesi ngaphandle kwesidingo sokubola ama-electrode ngokuncibilikisa i-electrolyte njengamabhethri endabuko, ngaleyo ndlela kwehlise ukuguga kwebhethri. Okwesibili, i-lithium iyinto encane futhi elula, eyenza amabhethri e-lithium-ion ahlangane futhi angasindi kumthamo ofanayo. Ngaphezu kwalokho, amabhethri e-lithium-ion nawo anezinzuzo zokuminyana kwamandla aphezulu, impilo yomjikelezo omude, futhi akukho mphumela wenkumbulo, konke okwenze amabhethri e-lithium-ion asetshenziswa kabanzi kumadivayisi kagesi aphathwayo, izimoto zikagesi nezinye izinkambu.
Ukuhlukaniswa kwamabhethri e-lithium
Amabhethri e-lithium-ion ahlukaniswa ngezigaba eziningana ngokusekelwe ezintweni zensimbi ezisetshenziswa ku-electrode enhle. Ekuqaleni, izinto zensimbi ezisetshenziswa ku-electrode enhle yamabhethri e-lithium-ion kwakuyi-cobalt. Kodwa-ke, ukukhiqizwa kwe-cobalt cishe kuphansi njengalokho kwe-lithium, futhi kuyinsimbi engavamile, ngakho-ke izindleko zokukhiqiza ziphezulu. Ngakho-ke, kwaqala ukusetshenziswa izinto ezishibhile nezingayingeni imvelo njenge-manganese, i-nickel nensimbi. Amabhethri e-lithium-ion ahlukaniswa ngokuya ngezinto azisebenzisayo. Ake sibheke izici zesigaba ngasinye.
| Izinhlobo zamabhethri e-Lithium-ion | Amandla kagesi | Izikhathi zokukhipha | Ubuhle nobubi |
| Amabhethri e-lithium-ion asekelwe ku-cobalt | 3.7V | 500 ~ 1000 izikhathi |
|
| I-lithium-ion esekelwe ku-Manganese | 3.7V | 300 ~ 700 izikhathi |
|
| Amabhethri e-lithium-ion asekelwe ku-iron phosphate | 3.2V | 1000 ~ 2000 izikhathi |
|
| Amabhethri e-lithium-ion asekelwe ku-Ternary | 3.6V | 1000 ~ 2000 izikhathi |

Ibhethri ye-lithium yakwa-Heltec Energy
Njengomkhiqizi ohamba phambili emkhakheni wamabhethri e-lithium, i-Heltec Energy iyaziqhenya ngamakhono ethu aqinile nokuzibophezela ekuletheni imikhiqizo yekhwalithi ephezulu kumakhasimende ethu. Ngokugxila emisha nasekusimameni, sizenzele njengomhlinzeki othembekile wezixazululo ezithuthukisiwe zebhethri ye-lithium.
Omunye wemikhiqizo yethu ephambili ibhethri ye-lithium, ethole ukuqashelwa kabanzi ngokusebenza kwayo okuphezulu nokuthembeka. Lawa mabhethri aklanyelwe ukuhlangabezana nesidingo esikhulayo sezixazululo zokugcina amandla ezinhlelweni ezihlukahlukene, okuhlanganisa ibhethri ye-forklift, ibhethri yenqola yegalofu, ibhethri eseliphelile, njll. Ngokugxila ekuphepheni nasekusebenzeni kahle, amabhethri ethu e-lithium akhiwe ukuze alethe amandla ahlala isikhathi eside kuyilapho enciphisa umthelela wendawo. Uma unemibuzo noma ungathanda ukufunda okwengeziwe, sicela ungangabazifinyelela kithi.
