Kumvetsetsa koyambirira kwa mabatire a lithiamu
Takulandirani ku blog ya Heltec Energy! Mabatire a lithiamu-ion akhala mbali yofunika kwambiri ya moyo wathu watsiku ndi tsiku, zipangizo zamagetsi zomwe timadalira, monga mafoni a m'manja ndi laputopu, ngakhale magalimoto. Chitsanzo cha batire chinapangidwa chakumapeto kwa zaka za zana la 18, ndipo patha zaka zoposa mazana awiri kuchokera pamenepo. Mabatire a lithiamu-ion ndi amodzi mwa mitundu yatsopano kwambiri ya mabatire omwe amabadwa panthawi yopanga batire.
Mabatire amagawidwa kukhala mabatire owuma omwe angagwiritsidwe ntchito kamodzi kokha, "mabatire oyambira", ndi mabatire omwe amatha kuyitanidwanso ndikugwiritsidwa ntchito kangapo, "mabatire achiwiri". Mabatire a lithiamu-ion ndi mabatire achiwiri omwe amatha kuchangidwanso. Poyerekeza ndi mitundu ina ya mabatire, mabatire a lithiamu-ion ndi apadera mu kukula kwawo kophatikizika komanso katundu wopepuka, kuwapangitsa kukhala abwino pazida zamagetsi zonyamula. Kuphatikiza apo, amatha kusunga mphamvu zambiri zamagetsi, zomwe zimawapangitsa kukhala gwero lamphamvu lamagetsi.
Momwe mabatire a lithiamu-ion amapangira magetsi
Mfundo yaikulu yogwiritsira ntchito mabatire ndi yofanana, kuphatikizapo electrode yabwino (cathode), electrode negative (negative electrode), ndi electrolyte. Mkati mwa batire, electrolyte imalola ma ion kudutsa, pamene ma elekitironi amayenda kuchokera ku electrode yolakwika kupita ku electrode yabwino, motero amapanga magetsi. Kwa mabatire achiwiri, monga mabatire a lithiamu-ion, amatha kusunga ma elekitironi mu electrode yolakwika pasadakhale ndi kulipiritsa, ndipo batire ikatulutsidwa, ma elekitironi awa amapita ku electrode yabwino, potero amapanga magetsi.
Kenako, tiyeni tione makhalidwe ndi ubwino lithiamu-ion mabatire. Chifukwa chomwe mabatire a lithiamu-ion amawonekera pakati pa mabatire ambiri makamaka chifukwa cha mawonekedwe awo apadera komanso kusankha zinthu. Choyamba, mabatire a lithiamu-ion amagwiritsa ntchito zitsulo zokhala ndi lithiamu pa electrode yabwino ndi carbon (monga graphite) yomwe imatha kuyamwa ndi kusunga lithiamu pa electrode yoipa. Kapangidwe kameneka kamalola mabatire a lithiamu-ion kuti apange magetsi popanda kufunika kowononga ma elekitirodi posungunula ma electrolyte ngati mabatire achikhalidwe, potero amachepetsa kukalamba kwa batire. Kachiwiri, lithiamu ndi chinthu chaching'ono komanso chopepuka, chomwe chimapangitsa mabatire a lithiamu-ion kukhala ophatikizika komanso opepuka pamlingo womwewo. Kuonjezera apo, mabatire a lithiamu-ion ali ndi ubwino wokhala ndi mphamvu zowonjezera mphamvu, moyo wautali wautali, ndipo palibe zotsatira zokumbukira, zonsezi zapanga mabatire a lithiamu-ion omwe amagwiritsidwa ntchito kwambiri pazida zamagetsi, magalimoto amagetsi ndi zina.
Gulu la mabatire a lithiamu
Mabatire a lithiamu-ion amagawidwa m'magulu angapo kutengera zinthu zachitsulo zomwe zimagwiritsidwa ntchito mu electrode yabwino. Poyamba, zinthu zachitsulo zomwe zimagwiritsidwa ntchito mu electrode yabwino ya mabatire a lithiamu-ion zinali cobalt. Komabe, kupanga cobalt kumakhala kochepa kwambiri ngati kwa lithiamu, komanso ndichitsulo chosowa, choncho mtengo wopangira ndi wokwera. Choncho, zida zotsika mtengo komanso zoteteza chilengedwe monga manganese, faifi tambala, ndi chitsulo zinayamba kugwiritsidwa ntchito. Mabatire a lithiamu-ion amagawidwa malinga ndi zida zomwe amagwiritsa ntchito. Tiyeni tione makhalidwe a gulu lililonse.
| Mitundu ya Mabatire a Lithium-ion | Voteji | Nthawi zotulutsa | Ubwino ndi kuipa |
| Mabatire a lithiamu-ion opangidwa ndi Cobalt | 3.7 V | 500 ~ 1000 nthawi |
|
| Manganese-based lithiamu-ion | 3.7 V | 300 ~ 700 nthawi |
|
| Mabatire a lithiamu-ion opangidwa ndi iron phosphate | 3.2V | 1000 ~ 2000 nthawi |
|
| Mabatire a lithiamu-ion opangidwa ndi Ternary | 3.6 V | 1000 ~ 2000 nthawi |

Batire ya lithiamu ya Heltec Energy
Monga opanga otsogola pantchito ya mabatire a lithiamu, Heltec Energy imanyadira kuthekera kwathu kolimba ndikudzipereka popereka zinthu zapamwamba kwambiri kwa makasitomala athu. Poyang'ana zaluso komanso kukhazikika, takhazikitsa tokha ngati opereka odalirika a mayankho apamwamba a lithiamu batire.
Chimodzi mwazinthu zomwe timakonda kwambiri ndi batri ya lithiamu, yomwe yadziwika kwambiri chifukwa chakuchita bwino komanso kudalirika. Mabatirewa adapangidwa kuti akwaniritse kufunikira komwe kukukulirakulira kwa mayankho osungira mphamvu pazinthu zosiyanasiyana, kuphatikiza batire ya forklift, batire ya ngolo ya gofu, batire yomaliza, ect. Poganizira zachitetezo komanso magwiridwe antchito, mabatire athu a lithiamu amapangidwa kuti azipereka mphamvu zokhalitsa ndikuchepetsa kuwononga chilengedwe. Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, musazengereze kuterokufikira kwa ife.
