Fortum , the Finnish state - owned energy company , has said that recycling rates for lithium - ion batteries could increase from the usual 50 % to over 80 % through the use of new hydrometallurgical technology from Finnish company Nokia . This technology was developed by Finnish growth company Crisolteq. The technology enables silicon , lithium , manganese and nickel to be removed from the old batteries , and reused in new ones . Fortum is also carrying out pilots of " “ second - generation ” energy storage schemes , and is establishing a network of charging infrastructure . The global lithium - ion battery market is expected to increase to € 20bn ( $ 2016 ) by 2030 , from just € 1.7 m at present , according to the International Energy Agency .
