ʻO ka pākahiko kelepona maloʻo, i ʻike ʻia ma ke ʻano ʻepekema ʻo zinc-manganese, he pākahiko mua me ka manganese dioxide ma ke ʻano he electrode maikaʻi a me ka zinc ma ke ʻano he electrode maikaʻi ʻole, kahi e hana ai i ka hopena redox e hoʻoulu ai i ke au. ʻO nā pākahiko kelepona maloʻo nā pākahiko maʻamau i ke ola o kēlā me kēia lā a pili i nā huahana maʻamau honua, me nā kūlana kūloko a me ka honua no ka nui a me ke ʻano o ke kelepona hoʻokahi.
Loaʻa i nā pila kelepona maloʻo ka ʻenehana paʻa, ka hana paʻa, ka palekana a me ka hilinaʻi, maʻalahi e hoʻohana a me nā ʻano hana like ʻole. I ke ola o kēlā me kēia lā, ʻo nā hiʻohiʻona maʻamau o nā pila zinc-manganese ʻo No. 7 (pāka ʻano AAA), No. 5 (pāka ʻano AA) a pēlā aku. ʻOiai ke hoʻāʻo nei nā kānaka ʻepekema e ʻimi i kahi pākahi mua ʻoi aku ka liʻiliʻi a me ke kumukūʻai kūpono, akā a hiki i kēia manawa ʻaʻohe hōʻailona o ka holomua, hiki ke manaʻo ʻia i kēia manawa, a i ka wā lōʻihi, ʻaʻohe pākahi ʻoi aku ka maikaʻi o ke kumukūʻai e pani i nā pākahi zinc-manganese.
Wahi a ke ʻano electrolyte a me ke kaʻina hana like ʻole, ua māhele nui ʻia nā pila zinc-manganese i nā pila kalapona a me nā pila alkaline. Ma waena o lākou, ua hoʻomohala ʻia nā pila alkaline ma ke kumu o nā pila kalapona, a ʻo ka electrolyte ka potassium hydroxide. Hoʻohana ka pila alkaline i ke ʻano electrode ʻē aʻe mai ka pila kalapona i ke ʻano, a hoʻohana i ka potassium hydroxide electrolyte alkaline kiʻekiʻe, a hoʻohana i nā mea electrode hana kiʻekiʻe no nā electrodes maikaʻi a me nā electrodes maikaʻi ʻole, ma waena o ia mau mea electrode maikaʻi he manganese dioxide a ʻo ka mea electrode maikaʻi ʻole he pauka zinc.
Hoʻonohonoho ʻia nā pila alkaline ma ke ʻano o ka nui o ka zinc, ka nui o ka zinc, ka nui o ka manganese dioxide, ka nui o ka manganese dioxide, ka hoʻonohonoho electrolyte, ka mea hoʻopaʻa i ka corrosion, ka pololei o nā mea maka, ke kaʻina hana, a me nā mea ʻē aʻe, hiki ke hoʻonui i ka mana ma 10%-30%, ʻoiai ʻo ka hoʻonui ʻana i ka ʻāpana hopena o nā electrodes maikaʻi a me nā electrodes maikaʻi ʻole hiki ke hoʻomaikaʻi nui i ka hana hoʻokuʻu o nā pila alkaline, ʻoiai ka hana hoʻokuʻu kiʻekiʻe o ke au.
1. ʻO ke koi hoʻokuʻu aku i nā pila alkaline o Kina e hoʻokele i ka hana ʻana
I nā makahiki i hala iho nei, me ka hoʻolaha mau ʻana a me ka hoʻolaha ʻana i nā noi pākahiko alkaline, ua hōʻike ka mākeke pākahiko alkaline ma ke ʻano holoʻokoʻa i kahi ʻano piʻi mau, e like me nā helu helu o ka China Battery Industry Association, mai ka makahiki 2014, i hoʻokele ʻia e ka hoʻomaikaʻi mau ʻana o ka hana pākahiko cylindrical alkaline zinc-manganese, ua hoʻomau ka piʻi ʻana o ka hana pākahiko alkaline zinc-manganese o Kina, a i ka makahiki 2018, ʻo ka hana pākahiko alkaline zinc-manganese aupuni he 19.32 biliona.
I ka makahiki 2019, ua piʻi ka hana ʻana o nā pākahiko zinc-manganese alkaline a Kina i 23.15 biliona, a ʻo ka manaʻo i hui pū ʻia me ka hoʻomohala ʻana o ka mākeke pākahiko zinc-manganese alkaline a Kina i ka makahiki 2020, ua manaʻo ʻia e hiki aku ka hana ʻana o nā pākahiko zinc-manganese alkaline a Kina ma kahi o 21.28 biliona i ka makahiki 2020.
2. Ke hoʻomau nei ka hoʻomaikaʻi ʻana o ka pae hoʻokuʻu aku o nā pila alkaline o Kina
Wahi a nā helu helu o ka China Chemical and Physical Power Industry Association, ua hoʻomau ka hoʻomaikaʻi ʻana o ka nui o nā pākahiko alkaline a Kina mai ka makahiki 2014. 2019, ʻo ka nui o nā pākahiko alkaline a Kina he 11.057 biliona, piʻi 3.69% i kēlā me kēia makahiki. 2020, ʻo ka nui o nā pākahiko alkaline a Kina he 13.189 biliona, piʻi 19.3% i kēlā me kēia makahiki.
Ma ke ʻano o ka nui o nā mea i hoʻokuʻu aku ʻia, e like me ka hōʻike ʻana o nā helu helu a ka China Chemical and Physical Power Industry Association, mai ka makahiki 2014, ua hōʻike ka hoʻokuʻu ʻana aku o nā pila alkaline a Kina i kahi ʻano piʻi holoʻokoʻa. I ka makahiki 2019, ua hōʻea ka hoʻokuʻu ʻana aku o nā pila alkaline a Kina i $991 miliona, piʻi 0.41% i kēlā me kēia makahiki. I ka makahiki 2020, ua hōʻea ka hoʻokuʻu ʻana aku o nā pila alkaline a Kina i $1.191 biliona, piʻi 20.18% i kēlā me kēia makahiki.
Mai ka manaʻo o ka wahi i hoʻokuʻu ʻia aku ai nā pākahiko alkaline mai Kina mai, ua hoʻopuehu iki ʻia nā hoʻokuʻu aku o nā pākahiko alkaline mai Kina mai, ʻo nā wahi hoʻokuʻu aku he ʻumi i hui pū ʻia nā hoʻokuʻu aku o nā pākahiko alkaline he 6.832 biliona, e helu ana i 61.79% o ka huina o nā hoʻokuʻu aku; ʻo ka hui pū ʻana o nā hoʻokuʻu aku he $633 miliona, e helu ana i 63.91% o ka huina o nā hoʻokuʻu aku. I waena o lākou, ʻo ka nui o nā pākahiko alkaline i hoʻokuʻu aku i ʻAmelika Hui Pū ʻIa he 1.962 biliona, me ka waiwai hoʻokuʻu aku he 214 miliona kālā US, e kūlana mua ana.
3. ʻOi aku ka nāwaliwali o ke koi kūloko no ka pākaukau alkaline o Kina ma mua o nā mea i hoʻokuʻu ʻia aku
I hui pū ʻia me ka hana ʻana a me ka lawe ʻana mai a me ka lawe aku ʻana aku o nā pila zinc-manganese alkaline ma Kina, ua manaʻo ʻia mai ka makahiki 2018, ua hōʻike ʻia ka hoʻohana ʻana o nā pila zinc-manganese alkaline ma Kina i kahi ʻano oscillating, a i ka makahiki 2019, ʻo ka hoʻohana ʻana o nā pila zinc-manganese alkaline ma ka ʻāina he 12.09 biliona. Ua hui pū ʻia ka ʻike mua me ke kūlana lawe mai a me ka lawe aku a me ka wānana hana ʻana o nā pila zinc-manganese alkaline ma Kina i ka makahiki 2020 i ka makahiki 2020, ʻo ka hoʻohana ʻana o nā pila zinc-manganese alkaline ma Kina ma kahi o 8.09 biliona.
ʻO ka ʻikepili a me ka loiloi i luna nei mai Foresight Industrial Research Institute, ʻoiai ʻo Foresight Industrial Research Institute e hāʻawi i nā hoʻonā no ka ʻoihana, ka hoʻolālā ʻoihana, ka hoʻolaha ʻoihana, ka hoʻolālā pāka ʻoihana, ka hoihoi ʻana i nā hoʻopukapuka kālā ʻoihana, ka noiʻi hiki ke hōʻiliʻili kālā IPO, ke kākau ʻana i nā prospectus, a pēlā aku.
