Ibhethri le-dry cell, elaziwa ngokwesayensi ngokuthi i-zinc-manganese, liyibhethri eliyinhloko eline-manganese dioxide njenge-electrode enhle kanye ne-zinc njenge-electrode engemihle, eqhuba ukusabela kwe-redox ukuze ikhiqize ugesi. Amabhethri e-dry cell angamabhethri avame kakhulu empilweni yansuku zonke futhi angaphansi kwemikhiqizo ejwayelekile yamazwe ngamazwe, anezindinganiso ezivamile zasekhaya nezamazwe ngamazwe ngobukhulu kanye nesimo seseli elilodwa.
Amabhethri e-dry cell anobuchwepheshe obuvuthiwe, ukusebenza okuzinzile, ukuphepha nokuthembeka, kulula ukuwasebenzisa kanye nohlu olubanzi lwezicelo. Empilweni yansuku zonke, amamodeli avamile amabhethri e-zinc-manganese yiNombolo 7 (ibhethri lohlobo lwe-AAA), Nombolo 5 (ibhethri lohlobo lwe-AA) njalo njalo. Nakuba ososayensi bebelokhu bezama ukuhlola ibhethri eliyinhloko elingabizi kakhulu nelingabizi kakhulu, kodwa kuze kube manje akukho sibonakaliso sempumelelo, kungalindelwa ukuthi okwamanje, ngisho nangesikhathi eside, alikho ibhethri elingcono elingabizi kakhulu lokufaka esikhundleni samabhethri e-zinc-manganese.
Ngokusho kwe-electrolyte ehlukene kanye nenqubo, amabhethri e-zinc-manganese ahlukaniswe kakhulu ngamabhethri e-carbon kanye namabhethri e-alkaline. Phakathi kwawo, amabhethri e-alkaline akhiwa ngokusekelwe kumabhethri e-carbon, kanti i-electrolyte ikakhulukazi i-potassium hydroxide. Ibhethri le-alkaline lithatha isakhiwo se-electrode esiphambene nebhethri le-carbon ngesakhiwo, futhi lithatha i-alkaline electrolyte potassium hydroxide ephezulu, futhi lithatha izinto ze-electrode ezisebenzayo eziphezulu zama-electrode amahle nangalungile, phakathi kwawo izinto ze-electrode ezinhle kakhulu ziyi-manganese dioxide kanti izinto ze-electrode ezimbi kakhulu ziyi-zinc powder.
Amabhethri e-alkaline athuthukiswa ngokwenani le-zinc, ukuminyana kwe-zinc, inani le-manganese dioxide, ukuminyana kwe-manganese dioxide, ukwenza ngcono i-electrolyte, i-corrosion inhibitor, ukunemba kwezinto zokusetshenziswa, inqubo yokukhiqiza, njll., okungakhulisa umthamo ngo-10%-30%, kuyilapho ukwandisa indawo yokusabela kwama-electrode amahle nangalungile kungathuthukisa kakhulu ukusebenza kokukhishwa kwamabhethri e-alkaline, ikakhulukazi ukusebenza kokukhishwa kwamandla kagesi aphezulu.
1. Isidingo sokuthumela ngaphandle kwebhethri le-alkaline laseShayina ukuze kuqhutshwe ukukhiqizwa
Eminyakeni yamuva nje, ngokuthandwa nokukhuthazwa okuqhubekayo kwezicelo zamabhethri e-alkaline, imakethe yamabhethri e-alkaline iyonke ikhombisa ukuthambekela okuqhubekayo kokukhuphuka, ngokusho kwezibalo ze-China Battery Industry Association, kusukela ngo-2014, okuqhutshwa ukuthuthuka okuqhubekayo kokukhiqizwa kwamabhethri e-alkaline zinc-manganese cylindrical, ukukhiqizwa kwamabhethri e-alkaline zinc-manganese e-China kuqhubekile nokukhuphuka, kanti ngo-2018, ukukhiqizwa kwamabhethri e-alkaline zinc-manganese kazwelonke kwaba yizigidigidi eziyi-19.32.
Ngo-2019, ukukhiqizwa kwamabhethri e-alkaline zinc-manganese eShayina kwanda kwafinyelela ku-23.15 billion, kanti inani elilindelekile elihlanganiswe nokuthuthukiswa kwemakethe yamabhethri e-alkaline zinc-manganese eShayina ngo-2020 kulinganiselwa ukuthi ukukhiqizwa kwamabhethri e-alkaline zinc-manganese eShayina kuzoba cishe yi-21.28 billion ngo-2020.
2. Isikali sokuthumela ngaphandle kwebhethri le-alkaline eShayina siyaqhubeka nokuthuthuka
Ngokwezibalo ze-China Chemical and Physical Power Industry Association, umthamo wokuthunyelwa kwamabhethri e-alkaline e-China uqhubekile nokuthuthuka kusukela ngo-2014. Ngo-2019, umthamo wokuthunyelwa kwamabhethri e-alkaline e-China u-11.057 billion, ukhuphuke ngo-3.69% unyaka nonyaka. Ngo-2020, umthamo wokuthunyelwa kwamabhethri e-alkaline e-China u-13.189 billion, ukhuphuke ngo-19.3% unyaka nonyaka.
Ngokuphathelene nenani lokuthumela kwamanye amazwe, ngokusho kwezibalo ze-China Chemical and Physical Power Industry Association zibonisa ukuthi kusukela ngo-2014, ukuthunyelwa kwamanye amazwe kwamabhethri e-alkaline e-China kukhombisa ukuthambekela okukhuphukayo jikelele. Ngo-2019, ukuthunyelwa kwamanye amazwe kwamabhethri e-alkaline e-China kufinyelele ku-$991 million, okwenyuke ngo-0.41% unyaka nonyaka. Ngo-2020, ukuthunyelwa kwamanye amazwe kwamabhethri e-alkaline e-China kufinyelele ku-$1.191 billion, okwenyuke ngo-20.18% unyaka nonyaka.
Ngokombono wendawo lapho amabhethri e-alkaline athunyelwa khona eShayina, ukuthunyelwa kwamanye amazwe kwamabhethri e-alkaline eShayina kusakazeke kakhulu, izindawo eziyishumi eziphezulu zokuthunyelwa kwamanye amazwe amabhethri e-alkaline athunyelwe kwamanye amazwe angama-6.832 billion, ahlanganisa u-61.79% wesamba sokuthunyelwa kwamanye amazwe; ukuthunyelwa kwamanye amazwe okuhlangene kwama-$633 million, ahlanganisa u-63.91% wesamba sokuthunyelwa kwamanye amazwe. Phakathi kwazo, umthamo wokuthunyelwa kwamanye amazwe wamabhethri e-alkaline e-United States wawuyi-1.962 billion, onenani lokuthunyelwa kwamanye amazwe elingamadola aseMelika ayizigidi ezingu-214, obekwe endaweni yokuqala.
3. Isidingo sasekhaya samabhethri e-alkaline aseShayina sibuthakathaka kunesithunyelwa kwamanye amazwe
Uma kuhlanganiswa nokukhiqizwa nokungeniswa kanye nokuthunyelwa kwamanye amazwe kwamabhethri e-alkaline zinc-manganese eShayina, kulinganiselwa ukuthi kusukela ngo-2018, ukusetshenziswa okusobala kwamabhethri e-alkaline zinc-manganese eShayina kubonise ukuthambekela okuguquguqukayo, kanti ngo-2019, ukusetshenziswa okusobala kwamabhethri e-alkaline zinc-manganese ezweni kungamabhiliyoni ayi-12.09. Ukubona kusengaphambili kuhlanganiswe nesimo sokungeniswa kanye nokuthunyelwa kwamanye amazwe kanye nokubikezela kokukhiqizwa kwamabhethri e-alkaline zinc-manganese eShayina ngo-2020 kulinganise ukuthi ngo-2020, ukusetshenziswa okusobala kwamabhethri e-alkaline zinc-manganese eShayina kungamabhiliyoni ayi-8.09.
Idatha kanye nokuhlaziywa okungenhla kuvela ku-Foresight Industrial Research Institute, kuyilapho i-Foresight Industrial Research Institute inikeza izixazululo zemboni, ukuhlela izimboni, isimemezelo sezimboni, ukuhlela amapaki ezimboni, ukuheha ukutshalwa kwezimali kwezimboni, ucwaningo lokuthola imali nge-IPO, ukubhala ama-prospectus, njll.
