Advanced Coating Technologies to Improve Life and Safety of Lithium Ion Battery for Automotive Applications

To meet the high-energy requirement that can enable the 40-miles electric drive Plug in Hybrid Electric Vehicle (P-HEVs), long range electric vehicle (EV) and smart grid, it is necessary to develop stable and very high energy and high-power cathodes and anodes that when combined in a battery system must offer over 5,000 charge-depleting cycles, 15years calendar life as well as excellent abuse tolerance. These challenging requirements make it difficult for conventional battery systems to be adopted in P-HEVs and EVs. In this talk, we will present different advanced coating technologies that can stabilize the interface between electrodes and electrolyte leading to significant improvement of both cycle and calendar life as well as battery safety. The protective coating can be done at the particle level by either spraying nano particle of stable Aluminium fluoride on the secondary particle of the active cathode particles or polymerising a PEDOT conductive polymer to fully protect the secondary and primary particle of the cathode. Another alternative is to use functional electrolyte additives to form a robust coating film on the electrode by either reduction, oxidation or polymerization of the additive to form a passivation film that can prevent any side reaction between electrodes and electrolyte at both high voltage and high temperature. These coating technologies have proven to be very effective low cost approach to enhance battery safety and performance and can enable low cost long range electric vehicles.
