Kufambira mberi kutsva mukuzvipisa uye kukurumidza kuchaja mabhatiri emotokari yemagetsi
mota yemagetsi inozvipisa inokurumidza kuchaja bhatiri yakagadziridzwa neelectrochemical power centre yePennsylvania State University uye National Engineering Laboratory yemotokari dzemagetsi yeBeijing University yetekinoroji yakafambira mberi. Mhedzisiro dzayo dzakaburitswa mujenari redzidzo repasi rose Journal Journal yeNational Academy yeSainzi. Kazhinji, kana tembiricha yemotokari yechinyakare yemagetsi lithium-ion bhatiri yakadzikira kupfuura 10 ℃, iyo lithium ion mubhatiri inoungana uye ichiisa pacarbon cathode, zvichikonzera nguva yekuchaja uye kudzikisira kwebhatiri kugona.
Mhedzisiro iyi yekutsvagisa inogona kuona maminetsi gumi nemashanu ekuchaja nguva yega yega pa15 ℃, ive nechokwadi 0 kutenderera uye chete 4500% kugona kunonoka. Pasi pemamiriro mamwe chetewo, bhatiri re lithium-ion richava ne20% simba rekudzikisa mushure memakumi mashanu. Zvinonzwisiswa kuti bhatiri idzva relithium-ion rinowedzera jira rakatetepa nickel uye tembiricha inonzwa mudziyo pahwaro hwechinyakare lithium-ion bhatiri kuona kuti maerekitironi anogona kugadzira nzira kuburikidza nenickel sheet kana tembiricha yebhatiri yadzikira kupfuura. tembiricha yekamuri. Kuburikidza nekushomeka kwekushisa kwesimbi nickel, yazvino inogona kupisa iyo nhete nickel sheet. Kana tembiricha yebhatiri yakwira, inongotanga iyo electrode reaction yelithium-ion bhatiri uye kudzoreredza yakajairika kuchaja uye kuburitsa simba rekupa. Vatsvagiri vakati yazvino bvunzo prototype inogona kupa akavandudzwa mazano ekuti vagadziri ve lithium-ion bhatiri vashandise mota dzemagetsi pasina kukanganiswa nekupisa kwekunze kunyangwe munzvimbo dzinotonhora.
