Silicon could quadruple anode capacity if used to replace graphite in lithium - ion batteries , according to researchers from the University of Eastern Finland . Note: They made lithium - ion batteries more efficient by using nanoporous silicon , which also allows for better recyclability for the devices . The researchers will also use silicon alongside carbon nanotubes to improve electrical conductivity and durability . At present , silicon is too expensive for commercial , large - scale production , leading the team to examine if it could be produced from agricultural waste products .
