▍Kuhi Hoʻopaʻa inoa Pono (CRS)
Ua hoʻokuʻu ʻia ke Kuhina o Electronics & Information TechnologyʻEleke a me ka ʻike ʻenehana waiwai-koi no ka hoʻopaʻa inoa koi ʻana I- Hoʻolaha ʻia ma ka lā 7thSepatemaba, 2012, a ua hoʻomaka i ka lā 3rdʻOkakopa, 2013. ʻO nā mea e pono ai nā lako uila a me nā ʻike loea no ka hoʻopaʻa inoa ʻana, ka mea i kapa ʻia ʻo BIS certification, i kapa ʻia ʻo CRS registration/certification. Pono e hoʻopaʻa inoa ʻia nā huahana uila a pau i ka papa inoa o nā huahana hoʻopaʻa inoa i lawe ʻia i India a kūʻai ʻia paha ma ka mākeke India ma ka Bureau of Indian Standards (BIS). I Nowemapa 2014, ua hoʻohui ʻia he 15 mau ʻano huahana i hoʻopaʻa inoa ʻia. ʻO nā ʻāpana hou: nā kelepona paʻalima, nā ʻeke, nā waihona mana, nā lako mana, nā kukui LED a me nā mea kūʻai aku, etc.
▍BIS Battery Test Standard

Pūnaehana ʻōnaehana Lithium / pākahi: IS 16046 (Mahele 2): 2018/ IEC62133-2: 2017
Hoʻokomo ʻia ke kelepona paʻa kālā/battery ma CRS.
▍No ke aha MCM?
● Ua kālele mākou i ka palapala hōʻoia India no nā makahiki ʻoi aku ma mua o 5 a ua kōkua i ka mea kūʻai aku e loaʻa ka leka BIS pākahi mua o ka honua. A loaʻa iā mākou nā ʻike kūpono a me ka hōʻiliʻili waiwai paʻa i ke kahua hōʻoia BIS.
● Hoʻohana ʻia nā luna kiʻekiʻe o ka Bureau of Indian Standards (BIS) ma ke ʻano he kūkākūkā hōʻoia, e hōʻoia i ka pono o ka hihia a hoʻoneʻe i ka pilikia o ke kāpae ʻana i ka helu inoa.
● Hoʻolako ʻia me nā mākau hoʻonā pilikia piha ikaika i ka palapala hōʻoia, hoʻohui mākou i nā kumuwaiwai ʻōiwi ma India. Mālama ʻo MCM i ke kamaʻilio maikaʻi ʻana me nā luna BIS e hāʻawi i nā mea kūʻai aku i ka ʻike a me ka lawelawe ʻoi loa o ka ʻoihana.
● Ke lawelawe nei mākou i nā ʻoihana alakaʻi i nā ʻoihana like ʻole a loaʻa ka inoa maikaʻi ma ke kahua, kahi i hilinaʻi nui ʻia a kākoʻo ʻia e nā mea kūʻai aku.
I ka makahiki 1800, ua kūkulu ka physicist Italia ʻo A. Volta i ka puʻu voltaic, nāna i wehe i ka hoʻomaka ʻana o nā pākaukau kūpono a wehewehe ʻia no ka manawa mua i ke koʻikoʻi o ka electrolyte i nā mea mālama uila electrochemical. Hiki ke ʻike ʻia ka electrolyte ma ke ʻano he uila uila a me ka ion-conducting layer ma ke ʻano o ka wai a paʻa paha, i hoʻokomo ʻia ma waena o nā electrodes maikaʻi ʻole. I kēia manawa, hana ʻia ka electrolyte kiʻekiʻe loa ma ka hoʻoheheʻe ʻana i ka paʻakai lithium paʻa (e laʻa me LiPF6) i loko o ka mea hoʻoheheʻe carbonate organik ʻole wai (e laʻa me EC a me DMC). E like me ke ʻano o ka cell cell form a me ka hoʻolālā ʻana, ʻo ka electrolyte ka mea maʻamau no ka 8% a 15% o ke kaumaha o ke kelepona. ʻO ka mea ʻē aʻe, ʻo kona flammability a me ka ʻoi aku ka maikaʻi o ka pae wela hana o -10°C a 60°C ke keʻakeʻa nei i ka hoʻomaikaʻi hou ʻana o ka ikehu a me ka palekana. No laila, ua manaʻo ʻia nā ʻano hana electrolyte hou i mea e hiki ai ke hoʻomohala i ka hanauna hou o nā pilahi hou.
Ke hana nei nā mea noiʻi e hoʻomohala i nā ʻōnaehana electrolyte like ʻole. No ka laʻana, ka hoʻohana ʻana i nā mea hoʻoheheʻe fluorinated e hiki ai ke hoʻokō i ka paikikala metala lithium maikaʻi, nā electrolytes paʻa organik a inorganic paha e pōmaikaʻi ai i ka ʻoihana kaʻa a me nā "bateri aupuni paʻa" (SSB). ʻO ke kumu nui inā hoʻololi ka electrolyte paʻa i ka electrolyte wai mua a me ka diaphragm, hiki ke hoʻomaikaʻi nui ʻia ka palekana, ka ikehu hoʻokahi a me ke ola o ka pākaukau. A laila, hōʻuluʻulu nui mākou i ka holomua noiʻi o nā electrolytes paʻa me nā mea like ʻole.
Ua hoʻohana ʻia nā electrolytes paʻa ʻole i loko o nā mea hoʻopaʻa ikehu electrochemical pāʻoihana, e like me kekahi mau ʻeke kiʻekiʻe kiʻekiʻe rechargeable Na-S, Na-NiCl2 a me Li-I2 pākahi. Ma hope i ka makahiki 2019, ua hōʻike ʻo Hitachi Zosen (Iapana) i kahi pahu pahu paʻa paʻa āpau o 140 mAh e hoʻohana ʻia ma ka lewa a hoʻāʻo ʻia ma ka International Space Station (ISS). Hoʻokumu ʻia kēia pākaukau me ka sulfide electrolyte a me nā mea ʻē aʻe i hōʻike ʻole ʻia, hiki ke hana ma waena o -40°C a me 100°C. I ka makahiki 2021 ke hoʻolauna nei ka hui i kahi pākaukau paʻa kiʻekiʻe o 1,000 mAh. ʻIke ʻia ʻo Hitachi Zosen i ka pono o nā ʻenekini paʻa no nā wahi paʻakikī e like me ke ākea a me nā mea hana ʻoihana e hana ana i kahi ʻano maʻamau. Hoʻolālā ka hui e pāpālua i ka nui o ka pākaukau ma 2025. Akā i kēia manawa, ʻaʻohe mea hoʻohana i nā kaʻa uila ma waho o ka papa.
