Ibhethri yeseli eyomile, ngokwesayensi eyaziwa ngokuthi i-zinc-manganese, ibhethri eliyinhloko eline-manganese dioxide njenge-electrode ephozithivu kanye ne-zinc njenge-electrode engeyinhle, elenza ukusabela kwe-redox ukuze likhiqize amandla amanje. Amabhethri amaseli owomile angamabhethri ajwayelekile kakhulu empilweni yansuku zonke futhi ayingxenye yemikhiqizo yamazwe ngamazwe esezingeni, enezindinganiso ezivamile zasekhaya nezamazwe ngamazwe zosayizi nokuma kweseli elilodwa.
Amabhethri amaseli omile anobuchwepheshe obuvuthiwe, ukusebenza okuzinzile, ukuphepha nokwethembeka, kulula ukuwasebenzisa kanye nezinhlelo eziningi ezahlukene. Ekuphileni kwansuku zonke, amamodeli avamile amabhethri e-zinc-manganese ayi-7 (AAA uhlobo lwebhethri), No. 5 (AAA uhlobo lwebhethri) njalonjalo. Nakuba ososayensi bebelokhu bezama ukuhlola ibhethri eliyisisekelo elingabizi kakhulu nelingabizi kakhulu, kodwa kuze kube manje alukho uphawu lwempumelelo, kungalindeleka ukuthi okwamanje, ngisho nangesikhathi eside, akukho ukonga okungcono kakhulu kwezindleko. ibhethri esikhundleni samabhethri e-zinc-manganese.
Ngokusho kwe-electrolyte ehlukene kanye nenqubo, amabhethri e-zinc-manganese ahlukaniswe ikakhulukazi amabhethri e-carbon namabhethri e-alkaline. Phakathi kwabo, amabhethri ane-alkaline athuthukiswa ngesisekelo samabhethri e-carbon, futhi i-electrolyte ngokuyinhloko i-potassium hydroxide. Ibhethri le-alkaline lamukela ukwakheka kwe-electrode okuphambene ne-carbon battery ngesakhiwo, futhi lamukela izinga eliphezulu le-alkaline electrolyte potassium hydroxide, futhi lamukela izinto ezisebenza kahle kakhulu ze-electrode zama-electrode amahle noma ama-negative, phakathi kwawo okubalulekile kwe-electrode okuyi-manganese dioxide kanye ne-negative electrode material. ikakhulukazi i-zinc powder.
Amabhethri e-alkaline athuthukisiwe ngokwenani le-zinc, ukuminyana kwe-zinc, inani le-manganese dioxide, ukuminyana kwe-manganese dioxide, ukwenziwa ngcono kwe-electrolyte, i-corrosion inhibitor, ukunemba kwempahla eluhlaza, inqubo yokukhiqiza, njll., engakhuphula umthamo ngo-10% -30%, kuyilapho ukwandisa indawo yokusabela yama-electrode aqondile noma amabi kungathuthukisa kakhulu ukusebenza kokukhipha kwamabhethri e-alkaline, ikakhulukazi ukusebenza okuphezulu kwamanje kokukhipha.
1. Isidingo sokuthekelisa sebhethri ye-alkali yaseChina ukuze siqhube ukukhiqizwa
Eminyakeni yamuva nje, ngokusakazwa okuqhubekayo nokukhuthazwa kwezicelo zebhethri le-alkaline, imakethe yebhethri ye-alkali iyonke ikhombisa ukukhuphuka okuqhubekayo, ngokwezibalo ze-China Battery Industry Association, kusukela ngo-2014, eqhutshwa ukuthuthukiswa okuqhubekayo kwe-cylindrical alkaline zinc. -ukukhiqizwa kwebhethri ye-manganese, ukukhiqizwa kwebhethri ye-alkaline ye-zinc-manganese yaseChina kuye kwaqhubeka nokukhuphuka, futhi ngo-2018, ukukhiqizwa kwebhethri ye-alkaline ye-alkaline ye-zinc-manganese yayiyizigidi eziyizinkulungwane ezingu-19.32.
Ngo-2019, ukukhiqizwa kwebhethri ye-alkaline zinc-manganese yaseChina kukhuphuke kwafinyelela ezigidini eziyizinkulungwane ezingama-23.15, kanti okulindelwe kuhlanganiswe nokuthuthukiswa kwemakethe yamabhethri e-alkaline zinc-manganese yaseChina ngo-2020 kulinganiselwa ukuthi ukukhiqizwa kwebhethri ye-alkaline zinc-manganese yaseChina kuzoba cishe izigidigidi ezingama-21.28 ngo-2020.
2. Isilinganiso sokuthekelisa kwebhethri ye-alkaline yaseChina siyaqhubeka nokuba ngcono
Ngokwezibalo ze-China Chemical and Physical Power Industry Association, ivolumu yokuthunyelwa kwebhethri ye-alkaline yase-China iqhubekile nokuba ngcono kusukela ngo-2014. 2019, ivolumu yokuthunyelwa kwebhethri ye-alkali yaseChina iyizigidi eziyizinkulungwane eziyi-11.057, ikhuphuke ngo-3.69% unyaka nonyaka. Ngo-2020, ivolumu yokuthunyelwa kwebhethri ye-alkaline yaseChina iyizigidigidi eziyi-13.189, ikhuphuke ngo-19.3% unyaka nonyaka.
Mayelana nenani elithunyelwa ngaphandle, ngokusho kwezibalo ze-China Chemical and Physical Power Industry Association zikhombisa ukuthi kusukela ngo-2014, ukuthunyelwa kwebhethri le-alkaline lase-China kukhombisa umkhuba okhuphukayo okhuphukayo. Ngo-2019, ukuthunyelwa kwebhethri le-alkaline lase-China kwafinyelela ku-$991 million, kwenyuke ngo-0.41% unyaka nonyaka. Ngo-2020, ukuthunyelwa kwebhethri le-alkaline lase-China kwafinyelela ku-$1.191 billion, kwenyuke ngo-20.18% unyaka nonyaka.
Ngokombono wendawo lapho ukuthunyelwa kwebhethri le-alkaline laseShayina lithunyelwa kwamanye amazwe, ukuthunyelwa kwebhethri le-alkaline laseShayina kuhlakazekile uma kuqhathaniswa, izindawo eziyishumi eziphezulu ezithunyelwa kwamanye amazwe amabhethri e-alkaline ahlanganisa ukuthunyelwa kwamanye amazwe kwezigidigidi ezingu-6.832, okubalelwa ku-61.79% wengqikithi yokuthunyelwa kwamanye amazwe; ukuthunyelwa kwamanye amazwe okuhlanganisiwe kwezigidi ezingama-633 zamaRandi, okubalelwa ku-63.91% wesamba esiphelele sokuthunyelwa kwamanye amazwe. Phakathi kwazo, umthamo wokuthekelisa wamabhethri e-alkaline aye e-United States wawuyizigidi eziyizinkulungwane eziyi-1.962, enenani lokuthekelisa eliyizigidi ezingu-214 zamadola aseMelika, libalwa kuqala.
3. Isidingo sasekhaya sebhethri ye-alkaline saseShayina sibuthakathaka kunokuthunyelwa kwamanye amazwe
Kuhlanganiswe nokukhiqizwa nokungenisa kanye nokuthunyelwa kwamanye amazwe kwamabhethri e-alkaline zinc-manganese e-China, kulinganiselwa ukuthi kusukela ngo-2018, ukusetshenziswa okusobala kwamabhethri e-alkaline zinc-manganese e-China kubonise ukuthambekela okuguquguqukayo, futhi ngo-2019, ukusetshenziswa okusobala kwe-alkaline. amabhethri e-zinc-manganese ezweni angu-12.09 billion. Ukubona kusengaphambili okuhlangene nesimo sokungenisa nokuthekelisa kanye nesibikezelo sokukhiqizwa kwamabhethri e-alkaline zinc-manganese eChina ngo-2020 kulinganiselwa ukuthi ngo-2020, ukusetshenziswa okusobala kwamabhethri e-alkaline zinc-manganese eChina cishe kuyizigidi eziyizinkulungwane eziyi-8.09.
Idatha engenhla nokuhlaziywa kuvela ku-Foresight Industrial Research Institute, kuyilapho i-Foresight Industrial Research Institute inikeza izixazululo zemboni, ukuhlelwa kwezimboni, isimemezelo sezimboni, ukuhlelwa kwepaki yezimboni, ukuheha ukutshalwa kwezimali kwezimboni, ucwaningo lwe-IPO lokuqoqa imali, ukubhala kwe-prospectus, njll.
