Muzochitika zina, monga zida zoyambira, zowonjezera, kapena misika yomwe ikufuna ndalama zochepa komanso nthawi yayitali, sodium-ion ikhoza kukhala njira yokongola mtsogolo.
Kuchaja Mwachangu kwa Mbadwo Watsopano: Sikuti Ndi Ma Watt Aakulu Okha
Anthu ambiri amaganiza kuti kupanga mabatire atsopano kumangokhudza mphamvu yamagetsi. Komabe, ukadaulo wochaja mwachangu ukupita patsogolo kwambiri. Tsopano tikuwona liwiro la 67W, 100W, komanso lokwera kwambiri m'zida zina. Komabe, cholinga chachikulu cha kuchaja mwachangu kwa mbadwo watsopano sikungokhudza kuwonjezera mphamvu yamagetsi; koma ndi kusamalira kutentha ndi kusunga thanzi la maselo a batire.
Njira yodziwika bwino ndi batire ya "maselo awiri" kapena "maselo ambiri", pomwe batire imagawidwa m'maselo awiri omwe amalipiridwa motsatizana kapena mwanjira inayake. Izi zimathandiza kuti mphamvu yamagetsi ikhale yotsika pa selo iliyonse, kuwongolera kutentha bwino, komanso kuyitanitsa mwachangu popanda kuchedwetsa kuwonongeka.
Kuphatikiza apo, njira zosinthira mphamvu zochajira kutengera kutentha, kagwiritsidwe ntchito ka zinthu, ndi zizolowezi za ogwiritsa ntchito zikukhala zanzeru. Dongosololi lidzachepetsa mphamvu yochajira kumapeto kapena kugwira batri pamlingo winawake (monga 80–90%) foni ikasiyidwa yolumikizidwa usiku wonse, kenako malizitsani kuchajira wogwiritsa ntchito asanadzuke. Njirayi imakulitsa kwambiri moyo wa batri.
Dongosolo Loyang'anira Mabatire (BMS) ndi AI: Ubongo Womwe Uli M'mbuyo mwa Moyo wa Mabatire
Ukadaulo wamakono wa mabatire siwokhudza chemistry yokha, komanso kasamalidwe. Machitidwe Oyang'anira Mabatire (BMS) akuchulukirachulukira: amawunika mphamvu yamagetsi, mphamvu yamagetsi, kutentha, komanso kukana kwamkati kuti apewe zinthu zoopsa. Mu mafoni a m'manja, BMS imagwira ntchito limodzi ndi chip yamagetsi ndi mapulogalamu kuti igwirizane ndi magwiridwe antchito ndi magwiridwe antchito.
Mothandizidwa ndi AI, mafoni amatha kuneneratu nthawi yomwe ogwiritsa ntchito amafunikira mphamvu zambiri, nthawi yoti asunge, komanso momwe angagawire zinthu ku chiwonetsero, modemu ya 5G, CPU/GPU, ndi mapulogalamu akumbuyo. Zotsatira zake nthawi zambiri zimaoneka zosavuta—nthawi yayitali ya batri—koma kumbuyo kwa zochitikazo pali kusintha kovuta komwe kumapangitsa batri laling'ono kumva ngati “lalikulu.”
Zipangizo ndi Mapangidwe Atsopano: Kuchokera ku Maselo Opanda Matebulo Kupita ku Mapaketi Ogwira Ntchito Bwino
Palinso zinthu zatsopano zomwe zikuchitika m'njira yolumikizira mabatire. Mapangidwe "opanda matebulo" (opanda ma tabu achikhalidwe) ndi njira zamakono zokonzedwa bwino zitha kuchepetsa kukana kwamkati, kuchepetsa kutentha, ndikuwonjezera magwiridwe antchito. Kuphatikiza apo, kulongedza mabatire kukukhala kwanzeru: malo opanda kanthu mkati mwa foni akuchepa, kapangidwe kake kamalimbikitsidwa, ndipo gawo loteteza kutentha likukulitsidwa.
Opanga ena akugwiritsanso ntchito njira zolondola kwambiri zokonzera zinthu (kuyika zinthu m'magawo a ma electrode) kuti awonjezere kuchuluka kwa mphamvu. Njira imeneyi imalola mabatire kuti azitha kugwiritsa ntchito zinthu zambiri zomwe zimagwira ntchito mofanana, ndikuwonjezera mphamvu popanda kuwonjezera kukula kwenikweni.
Chitetezo ndi Zachilengedwe
Kugwira bwino ntchito kwa batri kuyenera kulinganizidwa ndi chitetezo. Zatsopano mu zolekanitsa, zinthu zokhazikika za electrolyte, ndi zowunikira zina zotenthetsera zikukhala zinthu zofunika kwambiri. Mafoni a m'manja alinso ndi zigawo zingapo zotetezera: kuyambira zida zamagetsi (ma fuse, kulamulira kutentha) mpaka mapulogalamu (zoletsa kuyatsa zikatentha).
Poganizira za chilengedwe, kubwezeretsanso zinthu kukuchulukirachulukira. Mabatire okhalitsa amachepetsa kuchuluka kwa zinthu zomwe zimasinthidwa. Kuphatikiza apo, kafukufuku wokhudza kuchepetsa kugwiritsa ntchito zipangizo zodula kapena zowononga kwambiri (kuphatikizapo kugwiritsa ntchito bwino cobalt) akupitilizabe kupita patsogolo. M'tsogolomu, mabatire omwe si amphamvu okha komanso obwezeretsedwanso mosavuta adzakhala muyezo womwe ukufunidwa kwambiri.
