Fortum solution recycles 80% of Li-ion battery material
A new solution from Fortum, a Finnish clean-energy company, increases the amount of material in Li-ion batteries that can be recycled to more than 80%, according to the company. The current EU-mandated recycling rate is only 50% of the total weight of the battery. First the company makes the used batteries safe for mechanical treatment,… Read more »
Battery metals see bigger gains in 2018 than EVs thanks to increasing battery capacity
In 2018, global deployment of nickel, graphite, copper, LCE, aluminum and cobalt by cell suppliers for passenger vehicles increased by 75% to 99% over the previous year, according to data from Adamas Intelligence’s EV Battery Capacity and Battery Metals Tracker. These growth rates are particularly remarkable considering that global EV registrations increased by just 67% over the… Read more »
