Flexible lipo batire

Kupeza kumeneku kunapangitsa ofufuza ena kupanga mitundu yatsopano ya mabatire a Li-ion osinthika omwe amagwiritsa ntchito zinthu zosavomerezeka monga zotanuka ma polima ndi zakumwa zamadzimadzi m'malo mwa ma electrolyte amadzi oyaka (chinthu chomwe chimalola ayoni kuyenda pakati pa maelekitirodi awiri). Makampani ambiri apanga zinthu zochokera kuzinthu zomwe zimagwiritsa ntchito magetsi. pa zipangizo zatsopanozi, ndipo nkhaniyi ifufuza mitundu iwiri ya mabatire osinthika omwe akupezekanso kuti agwiritse ntchito malonda.

Mtundu woyamba umagwiritsa ntchito electrolyte yokhazikika koma yokhala ndi cholekanitsa chophatikizika cha polima m'malo mwa polyethylene wamba kapena polypropylene. Izi zimapangitsa kuti ikhale yopindika kapena kupangidwa m'njira zosiyanasiyana popanda kusweka. Mwachitsanzo, Samsung posachedwapa adalengeza kuti apanga batri yotere yomwe imatha kusunga mawonekedwe ake ngakhale atakulungidwa pakati. Mabatirewa ndi okwera mtengo kuposa akale koma amatha kukhala nthawi yayitali chifukwa pali kukana kwamkati kuchokera ku maelekitirodi okhuthala ndi olekanitsa. Komabe, chobweza chimodzi ndi mphamvu zawo zocheperako: Amatha kusunga mphamvu zochulukirapo ngati batire ya Li-ion yofananira ndipo sangayimbitsidwenso mwachangu.

Batire yamtundu uwu ya Li-ion pakali pano imagwiritsidwa ntchito mu Zovala Zovala kuti ziyang'anire zizindikiro zofunika za thupi, komanso zimatha kuphatikizidwa ndi zovala zanzeru. Mwachitsanzo, Cute Circuit imapanga diresi lomwe limayang'anira kuchuluka kwa kuwonongeka kwa mpweya ndikuwachenjeza ogwiritsa ntchito pogwiritsa ntchito chowonetsa cha LED chakumbuyo pakakhala mikwingwirima pafupi ndi omwe wavalayo. Kugwiritsa ntchito batire yamtunduwu kumapangitsa kuti zikhale zosavuta kuphatikiza masensa mwachindunji muzovala popanda kuwonjezera kuchuluka kapena kusapeza bwino.

Mabatire a lithiamu amagwiritsidwa ntchito kwambiri pazinthu zogula monga mafoni a m'manja ndi laputopu, koma kusintha kwa mphamvu zake (mphamvu, kulemera kwake) kungayambitse ntchito zopindulitsa monga zipangizo zamankhwala ndi magalimoto amagetsi. Popeza mabatire ambiri amagwiritsa ntchito chosungira cholimba chokhala ndi maelekitirodi oyikidwa mkati, pakhala kafukufuku wozama ngati batire yosinthika ingapangidwe yomwe ingalole mawonekedwe osiyanasiyana ndi zida zomwe zingakhale zamphamvu kwambiri.

Magalimoto amagetsi omwe alipo pano ali ndi malire ochepa chifukwa cha mphamvu zochepa zamabatire zomwe zimachitika chifukwa chogwiritsa ntchito ma casing olimba. Mabatire osinthika amathanso kuvala pazovala kapena kukulunga pamalo osakhazikika, zomwe zimatsegula mwayi watsopano waukadaulo wovala. Kuonjezera apo, kusinthasintha kwakukulu kumatanthauza kuti mabatire akhoza kusungidwa mu malo olimba ndikugwirizana ndi mawonekedwe achilendo; izi zitha kubweretsa mabatire okhala ndi kukula kocheperako poyerekeza ndi omwe amavotera wamba.

Results:

Batire yosinthika yomwe imagwiritsa ntchito zojambula zachitsulo m'malo mwa maelekitirodi olimba apangidwa ndi ofufuza a pa yunivesite ya California, Berkeley. Kapangidwe kake kamakhala ndi chiyembekezo chogwira ntchito bwino kuposa zida zamakono chifukwa amapangidwa ndi mapepala owonda angapo atayikidwa palimodzi, zomwe zimapangitsa kuti mphamvu zambiri zikhale zosinthika. Zoyeserera zam'mbuyomu zogwiritsa ntchito zida zina monga graphene zidalephera chifukwa cha kufooka kwa zida izi komanso kusowa kwawo kwamphamvu. Komabe, mapangidwe atsopano azitsulo zachitsulo amatsatira ndondomeko yofanana ndi mabatire a lithiamu-ion malonda ndipo amalola kuti mayunitsiwa apangidwe pamtunda wa mafakitale popanda zovuta.

Mapulogalamu:

Mabatire osinthika a lipo amatha kutsogolera ku zida zamankhwala zomwe zimavalidwa mosavuta pathupi, magalimoto amagetsi okhala ndi magalimoto ambiri, ukadaulo wonyezimira womwe susokoneza kuyenda, ndi ntchito zina zomwe zimapezerapo mwayi pakuwonjezereka uku.

Kutsiliza:

Kafukufuku wa pa Yunivesite ya California Berkeley adapanga batire yosinthika yopangidwa ndi mapepala azitsulo owunjikidwa osagwiritsa ntchito zinthu zosalimba za graphene. Kapangidwe kameneka kamapereka mphamvu zochulukirachulukira kuposa zida zamakono pomwe zimakhala zosinthika kwathunthu. Mabatire a lipo osinthika alinso ndi ntchito zomwe zingatheke m'magalimoto amagetsi, ukadaulo wovala, ndi madera ena omwe kusinthasintha kowonjezereka kumakhala kopindulitsa.
