Makambani eChinese ari kuwedzera kuzvizivisa sevagadziri uye vagadziri vemabhatiri anovimbisa. Tekinoroji dzekune dzimwe nyika hadzingokopedzwi, asi dzinovandudzwa uye dzinoitwa muchigadzirwa chekutengesa.
Basa rakabudirira remakambani eChinese rinotungamira mukufambira mberi kusingadzivisike muhunhu hwebhatiri, kunyangwe isu, chokwadi, tingade "zvese kamwechete." Asi izvi hazviitike, asi bhatiri rine huwandu hweanopfuura 800 km uye pasina inodhura cobalt ichakurumidza kuoneka. Tichati mazvita kukambani yeChinese SVOLT Energy Technology.
Munguva pfupi yapfuura, manejimendi eSVOLT Energy, aimbove mubatsiri weChinese automaker Great Wall Motor, mutsetse mutsva wekugadzirwa kweanovimbisa mota lithium-ion mabhatiri. Mutsara uchabudisa marudzi maviri emabhatiri, asi ikozvino mune zviduku-zvishoma. Kugadzirwa kwakawanda kuchatanga muhafu yechipiri yegore rinouya. Zvigadzirwa zverudzii izvi?
Imwe mhando yebhatiri ichavimba ne115 Ah maseru ane simba density ye245 Wh/kg. Aya masero akarongwa kuti ashandiswe kuunganidza mabhatiri anogadzirwa nemhando dzakawanda dzemotokari dzemagetsi. Chigadzirwa chechipiri, maseru ane huwandu hwe226 Ah asina cobalt, achagadzirwa chete kuGreat Wall Motor, inoronga kuaisa pamotokari dzayo dzemagetsi ekutanga.
Sekureva kwemugadziri, masero matsva eL6 mubhatiri achapa mota yemagetsi huwandu hunosvika 880 km pamubhadharo mumwe chete. Hupenyu hwebhatiri hwakaziviswa hunodarika makore gumi nemashanu, hunogona kushandurwa kuita huwandu hunosvika 15 miriyoni km pasina kutsiva bhatiri.
Kuti uwane hunhu hunokatyamadza hwebhatiri, mainjiniya eChinese akagadzira huwandu hwetekinoroji uye tekinoroji maitiro, kutanga nekutsiviwa kwecobalt muanode ine nickel nezvimwe zvinhu. Semuenzaniso, lithium ions mubhatiri inotsiviwa nenickel ions, iyo inodzivirira kuparara kwe lithium panguva yekushanda kwebheteri. Izvi pachazvo zvakakonzera matambudziko ehunyanzvi, ayo zvino akagadziriswa zvinobudirira.
Pakavewo nezvimwe zvakawanda zvitsva mukugadzirwa kwemasero ebhatiri, pamwe nekudzokororwa kwekugadzira uye kushanda kweiyo yakawanda-sero bhatiri pack. Iyo nyowani bhatiri paki inoumbwa zvinoenderana neiyo matrix musimboti uye inogona kuyerwa nyore nyore kune yakatarwa paramita, iyo inoderedzawo mutengo wekugadzirwa kwebhatiri magungano.
Ngatiwedzerei kuti mabhatiri eSVOLT Energy asina cobalt anoshanda pane zvishoma zvishoma - 4,3-4,35 V. Imhaka yeizvi kuti simba ravo rakachengetwa rakachengetwa rakakwirira kudarika iro rekare re lithium-ion mabhatiri. Zvinoramba zvichionekwa maitiro avanoita mukuita.
