Lilemong tsa morao tjena, indasteri ea naha ea heso ea lithium-ion betri e tsoetse pele ka potlako, 'me karolo ea' maraka ea lefats'e e ntse e tsoela pele ho phahama.E tsamaisoa ke matsete a maholo indastering ea betri ea lithium-ion, tlhokahalo ea lisebelisoa tsa anode tsa lithium-ion betri e ntse e eketseha.Ha ho bapisoa le anode ea graphite, anode ea silicon e na le matla a mangata a matla le matla a matla a molumo.Matla a matla a betri ea lithium-ion a sebelisang lisebelisoa tsa silicon anode a ka eketsoa ka ho feta 8%, 'me matla a matla a matla a ka eketseha ka ho feta 10%,' me ka nako e ts'oanang ka kilowatt-hora ea betri Theko e ka eketseha. e fokotsoe ke bonyane 3%, kahoo thepa ea silicon anode e tla ba le tebello e pharaletseng ea kopo.
Silicon e sebelisoa e le lisebelisoa tse mpe tsa electrode bakeng sa libeteri tsa lithium, tse nang le matla a khethehileng a ho lahla a 4200m Ah·g-1, e leng boleng bo phahameng ba lipatlisiso.
