Kufambira mberi kutsva mukutsvaga kwemabhatiri e-micro-lithium-ion muDalian Institute of Chemical Technology

Nguva pfupi yadarika, timu yaWu Zhongshuai, muongorori weboka remaviri-dimensional zvinhu uye simba mudziyo wekutsvagisa boka reDalian Institute of Chemical Physics, Chinese Academy of Sciences, uye timu yaBao Xinhe, mudzidzi weChinese Academy of Sciences, vakagadzira planar yakabatanidzwa yakazara ne-multi-directional mass transfer, yakanakisa kushanduka uye kugadzikana kwekushisa kwepamusoro. Solid-state lithium-ion micro bhatiri. Zvakaenderana netsvagiridzo zvakaburitswa paNanoEnergy.

Nekukurumidza kuvandudzwa kwezvinopfekwa zvinopfekeka, zvidiki, uye zvakabatanidzwa zvemagetsi zvishandiso, zvinokasira kuvandudza-inoshanda, isingaremi, inopfekeka, uye chimiro-basa rakasanganiswa rinochinjika magetsi emagetsi uye matekinoroji avo. Lithium-ion bhatiri parizvino ndiyo inonyanya kushandiswa uye yakakurumbira masimba emagetsi munharaunda, asi ine matambudziko ekuchengetedza akadai saizi hombe, chimiro chakamira, kusachinjika, kudonha kweelectrolyte uye kupisa, saka zvakaoma kuzadzisa zvinodikanwa zvekuchinjika uye miniaturized. zvigadzirwa zvemagetsi. need.

Munguva pfupi yapfuura, timu yekutsvagisa yakatungamira mukugadzira iyo-yakasimba-nyika planar yakasanganiswa lithium-ion miniature bhatiri. Iyo lithium-ion micro bhatiri inoshandisa nano lithium titanate nanospheres seyakaipa electrode, lithium iron phosphate microspheres seyakanaka electrode, yakanyanya conductive graphene seyo isiri-metallic ikozvino muunganidzi, uye ion gel se electrolyte. Iyo ine planar muchinjika-chigunwe gadziriso uye haidi kushandisa yechinyakare Diaphragm uye simbi ikozvino muunganidzi.

Iyo yakawanikwa lithium-ion micro bhatiri ine mukana weakawanda-directional mass transfer, ichiratidza yakakwira vhoriyamu simba density ye125.5mWh/cm3, yakanakisa chiyero kuita; Yekupedzisira-yakareba kutenderera kugadzikana, inenge isina kuderedzwa kwehuwandu mushure me3300 kutenderera; uye yakanaka mechanical properties Flexible, iyo electrode chimiro hachizokuvadzwa uye electrochemical performance haizoshanduki zvakanyanya pasi pekudzokorora kukotama kana kumonyoroka.

Panguva imwecheteyo, iyo miniature yekuchengetera simba mudziyo inogona kushanda yakadzikama munzvimbo yepamusoro yekupisa ye100 ° C uye ine kugadzikana kutenderera kwenguva refu (1000 cycles). Uye zvakare, iyo lithium-ion bhatiri inogona kuona modular yekuzvibatanidza isina masimbi ekubatanidza, uye kuona inoshanda dhizaini yekubuda kwevoltage uye kugona. Naizvozvo, iyo lithium ion miniature bhatiri ine mukana wakakura mukushandiswa kwezvinochinjika uye miniaturized zvigadzirwa zvemagetsi.
