Hitachi yapanga batri ya lithiamu-ion kwa ofufuza a polar, astronauts ndi ozimitsa moto

Hitachi Zosen wayamba kutumiza zitsanzo za mabatire oyamba olimba a lithiamu-ion okhala ndi ma electrode okhala ndi sulfate. The electrolyte mu AS-LiB mabatire (zonse olimba lithiamu-ion batire) ndi mu boma olimba, ndipo osati mu madzi kapena gel osakaniza ngati boma, monga ochiritsira mabatire lifiyamu-ion, amene amatsimikizira angapo chinsinsi ndi wapadera mbali. za mankhwala atsopano.

Chifukwa chake, ma electrolyte olimba m'mabatire a AS-LiB samawotcha, samatuluka nthunzi komanso samaundana (osakhuthala) mpaka kutentha kwambiri. Kutentha komwe kwalengezedwa kwa mabatire a AS-LiB akuchokera -40 °C mpaka 120 °C. Panthawi imodzimodziyo, magawo ogwiritsira ntchito mabatire samasintha kwambiri pamtundu wonsewo. Kusakhalapo kwa zinthu zosasinthika kumapangitsa kuti mabatire azigwira ntchito mu vacuum. Matupi awo sadzatupa panthawi ya ntchito. Ndipo izi sizikutanthauza kuti mliri wa mabatire a lithiamu-ion - ngozi ya moto ndi kuphulika - sikuopseza kalasi iyi ya mabatire.

Poganizira zomwe zalembedwa, mabatire a AS-LiB akuyembekezeka kugwiritsidwa ntchito mumlengalenga, zida zamankhwala ndi zida zamafakitale. M'tsogolomu, Hitachi Zosen akuyembekeza kupanga mabatire olimba a lithiamu-ion kuti asungire mphamvu zokhazikika, ma network ogawa ndi magalimoto amagetsi.

Tsoka ilo, ndalama iliyonse ili ndi zovuta zake. Pankhani ya mabatire a Hitachi AS-LiB, awa ndi mphamvu zochepa zosungirako mphamvu ndi kusungidwa kwa mphamvu-to-weight ratio. Kampaniyo sinatchule magawo awa, koma kutengera chitsanzo - batire yokhala ndi mbali za 52 × 65,5 × 2,7 mm ndi kulemera kwa magalamu 25, mabatire okhala ndi electrolyte olimba kwambiri sangafikire 10% ya mawonekedwe ofanana a mabatire a lithiamu-ion. ndi electrolyte yamadzimadzi. Kwa zitsanzo za AS-LiB Hitachi, izi ndi 55,6 Wh/l ndi 20,4 Wh/kg. Koma ngati tiyerekezera chitukuko chatsopano ndi mabatire a nickel-cadmium kwa danga, ndiye kuti zonse sizoyipa kwambiri. Amalemera kawiri kokha ngati nickel-cadmium, poganizira mphamvu zosungidwa, ndipo amatha kupindula ndi kuchepa kwa thupi.

Mabatire a AS-LiB Hitachi ali ndi vuto linanso - kupanga kuyenera kuchitika m'malo a chinyezi chochepa kwambiri. Electrode imapanga mosavuta hydrogen sulfide ikaphatikizidwa ndi chinyezi. Choncho, Hitachi yapanga zipangizo zamakono ndi mafakitale kuti apange mabatire olimba a lithiamu-ion ndipo ali okonzeka kugulitsa zilolezo kuti akonzekere kupanga ndi makampani achitatu. Wopangayo ayamba kutumiza mabatire a AS-LiB asanafike Epulo 2020.
