Yakawanda sei lithium-ion simba rekuchengetedza simba kuitira kuti isu tigone kushandisa simba rinogoneka? [NGANO]

Masayendisiti kuMassachusetts Institute of Technology akaverengera kuti ndeapi mazinga esimba rinoda kuchengetwa kuitira kutsiva zvine pundutso zvidyarwa zvemagetsi zvechinyakare nemagetsi anogona kudzokororwa. Zvinoitika kuti neshanduko yakazara kune simba rinogoneka, mitengo inofanirwa kuchinjika kubva pamadhora mashanu kusvika pamadhora makumi maviri pakWh.

Mabhatiri anhasi anodhura anopfuura madhora zana pakilowatt awa.

Patova nerunyerekupe rwekuti vagadziri vakakwanisa kuderedza chiyero che100-120 madhora pa kilowatt-awa ye lithium-ion masero, iyo inodarika madhora matanhatu (kubva ku6 zloty) pasero kusvika pakati-kati-kati bhatiri yemotokari. Maseru ekuChina eCATL lithium iron phosphate anotarisirwa kuita isingasviki madhora 23 pakWh.

Nekudaro, sekureva kwevaongorori veMassachusetts Institute of Technology, izvi zvichiri zvakawandisa. Kana isu taida kushandisa chete simba rinogoneka uye kuchengetedza simba rakawandisa mumabhatiri e-lithium-ion, zvingave zvakakosha kuti tisiye. kusvika ku10-20 $ / kWh pakutsiva gwenya remagetsi enyukireya. Kumagetsi emagetsi emagetsi emagetsi - kuverenga kunobva kuUnited States, iyo ndiyo nyika yechina yakakura yekugadzira gasi rechisikigo - mari yebhatiri ye lithium-ion inofanira kunge yakaderera - madhora mashanu chete pakWh.

Asi heino kuda kuziva: mari iri pamusoro inofungidzira zvakajairika kutsiva iyo yakatsanangurwa masimba emagetsi neanogona kudzorerwazve simba, ndiko kuti, zvivako zvekuchengetedza simba zvakakwana kuti zvizadzise zvinodikanwa kwenguva yakareba yekunyarara uye kusina chiedza chezuva. Kana zvinodzokororwa zvakawanikwa zvichigadzira "chete" 95 muzana yesimba, chengetedzo yesimba inoita kuti hupfumi huve nepfungwa pamadhora zana nemakumi mashanu / kWh!

Tave kutosvika padanho remadhora zana nemakumi mashanu pakilowatt-awa. Dambudziko nderekuti hakuna mafekitari ebhatiri e-lithium-ion akakwana munyika kuti asangane nezvinodiwa nevagadziri vemotokari, ndoda zvitoro zvikuru zvemagetsi. Ndezvipi zvimwe zvingasarudzwa? Vanadium inoyerera mabhatiri ari nyore kugadzira, asi anodhura ($150/kWh). Matangi ekuchengetera kana mayunitsi emhepo akatsikirirwa akachipa ($100/kWh) asi zvinoda nzvimbo huru nemamiriro enzvimbo akakodzera. Mamwe ese akachipa matekinoroji ari chete padanho rekutsvagisa nekusimudzira - isu tinotarisira budiriro munguva pfupi yapfuura mumakore mashanu.

Zvakakodzera kuverenga: Kuchengetedzwa kwesimba kunoda kudhura zvakadii kuti zvishandiso zvichinje ku100% simba rinowanikwazve?

Mufananidzo wekuvhura: Tesla simba rekuchengetedza padyo neTesla solar farm.
