Battery layer systems

Applications

• smartcards
• Radio Frequency Identification Devices, RFID’s
• autonomous sensor-systems and networks
• thin-film-batteries for medical applications (e.g. cardiac pacemakers, active micro-pills)
• microelectromechanical systems (MEMS), lab-on-a-chip
• mobile electronic devices (mobile phones, tablets, laptops, digital cameras, mp3-player)

Advantages

• non-flammable solid electrolytes, high intrinsic safety-level
• environment-friendly operation
• possible integration into micro systems due to small size
• absent passivation of the electrodes surface (no liquid electrolyte involved), higher battery cycling lifetime
• increased specific capacity and energy density by using multivalent ions as charge carriers
• further enhancement of characteristic electrochemical performance possible by creating 3D-systems
• charging can occur even at electrical currents as low as 100 nA
• continuous discharge even at high temperatures (small internal electric resistance)
• parallel- and series connection of cells for yielding higher electrical voltage/ currents
• low production costs by substituting expensive and determinate available raw materials like Li, Co, Ge
