▍He aha ka CB Certification？
ʻO IECEE CB ka ʻōnaehana honua maoli mua no ka ʻike like ʻana i nā hōʻike hoʻāʻo palekana uila.Loaʻa ka NCB (National Certification Body) i kahi ʻaelike multilateral, e hiki ai i nā mea hana ke loaʻa ka palapala hōʻoia aupuni mai nā ʻāina lālā ʻē aʻe ma lalo o ka papahana CB ma ke kumu o ka hoʻoili ʻana i kekahi o nā palapala hōʻoia NCB.
ʻO ka palapala CB he palapala hoʻolālā CB kūhelu i hoʻopuka ʻia e ka NCB ʻae ʻia, ʻo ia hoʻi ka hōʻike ʻana i nā NCB ʻē aʻe i kūpono nā laʻana huahana i hoʻāʻo ʻia me nā koi maʻamau.
E like me ke ʻano o ka hōʻike maʻamau, hōʻike ʻo CB i nā koi kūpono mai ka IEC maʻamau i kēlā me kēia mea.ʻAʻole wale ka hōʻike CB e hāʻawi i nā hopena o nā hoʻāʻo a pau e pono ai, ana, hōʻoia, nānā ʻana a me ka loiloi me ka akaka a me ka ʻole ambiguity, akā pū kekahi me nā kiʻi, ke kiʻi kaapuni, nā kiʻi a me ka wehewehe ʻana o ka huahana.Wahi a ke kānāwai o ka hoʻolālā CB, ʻaʻole e mana ka hōʻike CB a hiki i ka hōʻike pū ʻana me ka palapala CB.
▍ No ke aha mākou e pono ai i ka CB Certification?
- pololeilyʻikezed or aponoednalālāʻāina
Me ka palapala hōʻoia CB a me ka hōʻike hoʻāʻo CB, hiki ke lawe pololei ʻia kāu huahana i kekahi mau ʻāina.
- E hoʻohuli i nā ʻāina ʻē aʻe palapala hōʻoia
Hiki ke hoʻololi pololei ʻia ka palapala CB i ka palapala hōʻoia o kona mau ʻāina lālā, ma ka hāʻawi ʻana i ka palapala CB, hōʻike hōʻike a me ka hōʻike hōʻike ʻokoʻa (inā pili) me ka ʻole o ka hana hou ʻana i ka hoʻāʻo, hiki ke hōʻemi i ka manawa alakaʻi o ka hōʻoia.
- E hōʻoia i ka palekana o ka huahana
Noʻonoʻo ka hōʻike hōʻoia CB i ka hoʻohana kūpono o ka huahana a me ka palekana i ʻike ʻia ke hoʻohana hewa ʻia.ʻO ka huahana i hōʻoia ʻia e hōʻoia i ka ʻoluʻolu o nā koi palekana.
▍No ke aha MCM?
● Pono:ʻO MCM ka CBTL mua i ʻae ʻia o IEC 62133 maʻamau maʻamau e TUV RH ma ka ʻāina nui o Kina.
● hiki ke hōʻoia a hoʻāʻo:ʻO MCM kekahi o ka papa mua o ka hoʻāʻo ʻana a me ka hōʻoia ʻana i ka ʻaoʻao ʻekolu no ka maʻamau IEC62133, a ua hoʻopau ʻoi aku ma mua o 7000 pākaukau IEC62133 hōʻike a me nā hōʻike CB no nā mea kūʻai aku honua.
● Kākoʻo ʻenehana:Loaʻa iā MCM ma mua o 15 mau ʻenehana loea loea i ka hoʻāʻo ʻana e like me ke kūlana IEC 62133.Hāʻawi ʻo MCM i nā mea kūʻai aku me nā ʻano kākoʻo ʻenehana piha, pololei, pani pani ʻia a me nā lawelawe ʻike alakaʻi.
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 hoʻokumu ʻana o nā electrolyte hou i mea e hoʻomohala ai i ka hanauna hou o nā pākahi hou. Ke hana pū 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.
