It is understood that copper foil for lithium ion battery has soared to¥78/kg, amount of increasing is¥6 /kg, while manufacturers expect by the end of this year rise to ¥80/kg or more is a high probability event.
According to professionals, high-speed lithium ion battery copper foil growth extrude circuit board production, resulted circuit board copper price rose from previous ¥60/ kg to¥76-78/ kg, with a rate of 30%. Even though copper foil manufacturers are also expanding producing capacity, but up to 2 years expansion cycle is difficult to solve the current predicament. It is expected by the end of 2017, the copper foil short supply will be continued.
