Hitachi Zosen atanga kutumira masampula eiyo indasitiri yekutanga solid-state lithium-ion mabhatiri ane sulfate-ine electrodes. Iyo electrolyte muAS-LiB mabhatiri (all-solid lithium-ion bhatiri) iri mumamiriro akasimba, uye kwete mune yemvura kana gel-yakafanana mamiriro, seyakajairwa lithium-ion mabhatiri, ayo anosarudza akati wandei akakosha uye akasiyana maficha. yechigadzirwa chitsva.
Saka, iyo yakasimba electrolyte mumabhatiri eAS-LiB haipisi, haiputsi uye haina kugwadama (haisi kukobvu) kusvika kune yakaderera tembiricha. Iyo yakaziviswa yekushanda tembiricha yemhando yemabhatiri eAS-LiB kubva -40 Β°C kusvika 120 Β°C. Panguva imwecheteyo, maitiro ekushanda emabhatiri haashanduki zvakanyanya pamusoro pehuwandu hwose. Kusavapo kwezvinhu zvinoputika zvinobvumira mabhatiri kuti ashande muvhavha. Miviri yavo haizozvimba panguva yekushanda. Uye izvi hazvirevi chokwadi chokuti denda re lithiamu-ion mabhatiri - ngozi yemoto uye kuputika - haingotyisidzi iyi kirasi yebhatiri.
Tichifunga nezvezvivakwa zvakanyorwa, mabhatiri eAS-LiB anotarisirwa kushandiswa muspacecraft, zvishandiso zvekurapa uye zvemaindasitiri. Mune ramangwana, Hitachi Zosen anotarisira kuburitsa yakasimba-state lithium-ion mabhatiri ekuchengetedza simba rekuchengetedza, kugovera network uye mota dzemagetsi.
Sezvineiwo, mari yese ine zvayakaipira. Panyaya yeHitachi AS-LiB mabhatiri, aya mashoma ekuchengetedza simba density uye akachengetwa simba-kusvika-uremu reshiyo. Kambani haina kutsanangura maparamendi aya, asi tichitarisa nemuenzaniso wakaunzwa - bhatiri rine mativi e52 Γ 65,5 Γ 2,7 mm uye huremu hwemagiramu makumi maviri nemashanu, mabhatiri ane yakasimba-state electrolyte haatombosviki 25% yezvakafanana mabhatiri e lithium-ion. ine liquid electrolyte . Kumuenzaniso weAS-LiB Hitachi, idzi 10 Wh/l uye 55,6 Wh/kg. Asi kana tikaenzanisa kuvandudzwa kutsva ne nickel-cadmium mabhatiri panzvimbo, ipapo zvose hazvina kunyanya kuipa. Iwo anongorema zvakapetwa kaviri senickel-cadmium, uchifunga nezvesimba rakachengetwa, uye anogona kubatsirwa nekudzikiswa uremu hwemuviri.
AS-LiB Hitachi mabhatiri ane imwezve yakashata - kugadzirwa kunofanirwa kuitika mumamiriro ehunyoro hwakanyanya. Electrode zvinhu zvinogadzira nyore hydrogen sulfide kana yasanganiswa nehunyoro. Naizvozvo, Hitachi yakagadzira tekinoroji uye zvigadzirwa zvemaindasitiri zvekugadzira yakasimba-state lithium-ion mabhatiri uye yakagadzirira kutengesa marezinesi kuronga kugadzirwa nemakambani echitatu. Iye anovandudza anotanga kutengesa kutengesa mabhatiri eAS-LiB pamberi paApril 2020.
