Abstract [en]

  Rechargeable lithium-ion (Li-ion) batteries have high energy and power densities and are therefore the primary choice for application in consumer electronics. Although new electrode materials for Li-ion batteries are developed continuously, relative little attention has so far been paid to the use of electrochemical manufacturing methods. In the field of microbatteries, electrodeposition has, however, become one of the main techniques employed for the manufacturing of current collectors, electrode materials and electrolytes [1,2]. It has also been shown that electrochemically nanostructured electrodes lacking binders and other additives can be employed to provide more information regarding the electrochemical processes taking place in Li-ion batteries [1,2].   

This presentation will focus on our recent work aiming at the development of electrochemical approaches for the manufacturing and study of nanostructured electrode materials for Li-ion batteries. It will be shown that electrodeposition can be used for the manufacturing of 3-D copper and aluminium [1] current collectors as well as the coating of these with thin layers of anode or cathode materials. Electrochemical manufacturing and characterisation of materials such as Cu2O coated nanorods [2,3], Sn/SnO2 particles [4] and TiO2 nanotubes will be discussed as well as a new approach for the manufacturing of TiO2 nanotube size gradient based electrodes [5]. Some fundamental issues regarding the electrochemical processes in Li-ion battery materials, including nanoeffects, will likewise be discussed.
