Msika Wosungira Mphamvu Ikukula Mofulumira

Electrochemical energy yosungirako imayang'aniridwa ndimabatire a lithiamu-ion, yomwe ndi teknoloji yosungiramo mphamvu yomwe ili ndi machitidwe ambiri ochuluka kwambiri komanso kuthekera kwakukulu kwachitukuko.Mosasamala kanthu kuti ndi msika wamasheya kapena msika watsopano, mabatire a lithiamu ali ndi udindo wokhazikika pakusungirako mphamvu zamagetsi.Padziko lonse lapansi, kuyambira 2015 mpaka 2019, kupindula ndikukula mwachangu kwa mabatire a lithiamu, gawo lalithiamu-ion batire mphamvu yosungirakomsika wapakhomo unakwera kuchokera ku 66% kufika ku 80,62%.

Kutengera kugawa kwaukadaulo, pakati pa ntchito zatsopano zosungiramo mphamvu zamagetsi padziko lapansi, mphamvu yoyika ya mabatire a lithiamu-ion ndi gawo lalikulu la 88%;Kusungirako kwamphamvu kwa batire ya lithiamu m'nyumba kudafikira 619.5MW ya mphamvu zatsopano zoyikidwira chaka chonse mu 2019, chiwonjezeko cha 16.27% motsutsana ndi zomwe zikuchitika Mumsika watsopano, kulowetsedwa kwa mabatire a lithiamu kudakwera kuchoka pa 78.02% mu 2018 mpaka 97.27%.

Pakali pano, mabatire a lithiamu-ion ndi mabatire a lead-acid ndiye njira zazikulu zamakono zosungira mphamvu zamagetsi, ndipo ntchito yayikulu ya mabatire a lithiamu-ion ndi yabwino kuposa mabatire a lead-acid, ndipo pang'onopang'ono idzalowa m'malo mwa mabatire a lead-acid. m'tsogolomu, ndipo gawo la msika likuyembekezeka kupitiliza kuwonjezeka.

Poyerekeza ndi mabatire amtundu wa lead-acid, mabatire a lithiamu ali ndi maubwino atatu akulu: (1) Kuchulukitsitsa kwa mphamvu kwa mabatire a lithiamu-ion ndi kuwirikiza ka 4 kuposa mabatire a lead-acid, ndipo mphamvu ndi kulemera kwake kuli bwino kuposa mabatire a lead-acid. ;(2) Mabatire a Li-ion ndi ochezeka kwambiri ndi chilengedwe, ndipo mabatire a lithiamu-ion ndi otetezeka ku chilengedwe.Batire ilibe zinthu zovulaza monga mercury, lead, ndi cadmium.Ndi batire yobiriwira yeniyeni.Kuphatikiza apo, mabatire a lithiamu-ion ali ndi mphamvu zambiri komanso amakhala ndi mphamvu zosinthira mphamvu kuposa mabatire otsogolera.Chiwopsezo cha ndondomekoyi ndi chochepa kuposa cha mabatire otsogolera;(3) Lithiamu-ion imakhala ndi moyo wautali wozungulira.Pakalipano, moyo wa mabatire a lithiamu-ion nthawi zambiri umakhala kuwirikiza katatu kapena kanayi kuposa wa mabatire a lead-acid.Ngakhale mtengo woyamba ndi wapamwamba, umakhala wokwera mtengo kwambiri pakapita nthawi.

M'kupita kwa nthawi, "photovoltaic + mphamvu yosungirako"Kuphatikizana kwa mtengo wamagetsi wamagetsi ndicho cholinga chachikulu cha kuzindikira photovoltaics monga mbadwo watsopano wa mphamvu kwa anthu m'zaka 100 zikubwerazi.Economics yakhala gawo lalikulu lomwe likuyendetsa kukula kwachuma.
