A lithium-ion cell is described comprising a positive electrode, a negative electrode and a separator that is permeable to lithium ions, which migrate back and forth between the positive and negative electrode during charging and discharging of the cell. T...

Carbon particles having average particle size of 1-100 mu m are intercalated and mixed with silicon particles having average particle size of 5-500 nm. An amorphous carbon polymer or polymer precursor is added, and mixture is heat-treated in the absence of...

The method involves depositing a mixture comprising particles of electrochemical active material, a binder, solvent and electrochemical dispersing agent on an electrical conductive substrate e.g. aluminum substrate and copper substrate, where amount of the...
