ADVANCED RECHARGEABLE BATTERIES: A GREAT CHALLENGE IN MATERIALS SCIENCE. WHAT ARE THE HORIZONS FOR ELECTROCHEMICAL PROPULSION AND LARGE ENERGY STORAGE BY ELECTROCHEMICAL DEVICES?

The successful use of Li ion batteries in providing a most reliable power sources for all kinds of portable electronic devices, promotes them to much more challenging applications, namely, electro-mobility - a massive development and commercialization of electric vehicles. Major demands from EV batteries are very high energy density, prolonged durability (cycle life) and zero fault safety. We will review in the presentation the most relevant electrodes materials and electrolyte systems that mark the true horizons for such batteries. We will also discuss which battery systems are suitable for large energy application. Here a key point is the use of materials which elements are the most abundent in earth crust. We will demonstrate several attractive options. The success of Li ion battery technology promotes development of new systems such as Na and K ion batteries, Li-S and Li-oxygen batteries. We will discuss briefly their current status.
