The transportation landscape is changing and vehicle electrification continues to gain traction in the market.  The trend towards electric mobility (e-mobility) has shown a significant rise in recent years along with advances in technology and government subsidies, but there is still a long way to go for the future of e-mobility to be realized. The heart of e-mobility is the battery and its performance is fundamental to the success of e-mobility. 

The cathode has a large stake in the key characteristics of the battery, such as energy density, power capability, safety, and cost.  Advancements of cathode materials directly result in the improved battery performance with higher significance.  BASF has focused on the development of next generation cathode materials (high energy Li-Mn-rich NCM and high voltage spinel) as well as advanced surface modification techniques.

In this presentation, we will report the electrochemical behaviors of a few of our latest cathode materials for advanced lithium-ion batteries.  Three-electrode cell testing results will reveal in-depth information regarding early stage electrochemical formation process as well as cycling performance.  Subsequently performed post-mortem investigation will provide analysis of capacity fade and failure mechanism during/after cycling procedure.  Also, insights on the path forwards to further improve battery performance will be shared.
