Sida aynu wada ognahay, fkm (fluoroelastomer) qiimihiisu aad ayuu kor ugu kacay 2021. Waxana uu gaadhay qiimihii ugu sarreeyey dhamaadkii 2021. Qof kastaa waxa uu mooday in uu hoos u dhici doono sanadka cusub. Bishii Febraayo 2022, fkm qiimihiisu wuxuu u muuqday mid yar. Iyadoo intaas ka dib, suuqa ayaa leh macluumaad cusub oo ku saabsan isbeddelka qiimaha. Waxa laga yaabaa in aanay aad u yarayn sidii aynu saadaalinay. Taas beddelkeeda, qiimaha sarreeya ayaa sii hayn doona muddo dheer. Iyo xaalada ugu xun ee ay mar kale sii kordhin doonto. Maxay tani u dhici doontaa?
Baahida PVDF ee loo isticmaali karo cathodes baytariyada lithium ayaa si aad ah u kordheysa. Sida laga soo xigtay warbixinnada, baahida caalamiga ah ee PVDF ee batteriga lithium cathodes ee 2021 waxay ahayd 19000 tan, iyo 2025, baahida caalamiga ah waxay noqon doontaa ilaa 100 kun oo tan! Baahida weyni waxay sababtaa qiimaha alaabta ceeriin ee R142 kor u kaca. Ilaa maanta qiimaha R142b ayaa wali kor u sii kacaya. R142b sidoo kale waa monomer ah fluoroelastomer. Fluoroelastomer-ka guud ee copolymer waxaa polymerized by VDF (vinylidene fluoride) iyo HFP (hexafluoropropylene) Kahor Sebtembar 2021, qiimaha copolymer-ka cayriin waa qiyaastii $8-$9/kg. Ilaa Diseembar 2021 qiimaha copolymer xanjo waa $27~$28/kg! Noocyada caalamiga ah sida Solvay Daikin iyo Dupont ayaa u beddelaya diiradda ganacsi faa'iido badan leh. Sidaa darteed yaraantu way sii kordhaysaa. Baahida sare iyo wali kor u kaca qiimaha ayaa sababa in qiimaha fluoroelastomer uu kor u kaco mana hoos u dhici doono wakhti dheer.
Dhawaan mid ka mid ah alaab-qeybiyaha xanjada ceyriinka ee fkm weyn ayaa joojisay bixinta fkm. Iyo alaab-qeybiye kale ayaa ku dhawaaqay kor u kaca qiimaha mar hore. Markii uu dhawaan ka dillaacay COVID-19 Shiinaha, waxaan u maleyneynaa in qiimaha sarreeya uu sii jiri doono. Fadlan la xidhiidh kooxdayada iibka qiimaha la cusboonaysiiyay oo u hagaaji kaydkaaga si macquul ah. Waxaan rajeyneynaa inaan ka gudbi karno waayaha adag ee gacmaha is haysta.
