Invited Paper TF+EN+PS-TuA3
Applications of ALD for Li ion Batteries and Low Temperature Fuel Cells

Tuesday, November 11, 2014, 3:00 pm, Room 307

Atomic layer deposition (ALD) is a novel and unique coating technique with many applications in energy storage and conversion [1]. In this talk, I will present our recent work on exploring the applications of atomic layer deposition (ALD) in both fuel cells and Li ion batteries [2-7].

In the first part, we will report of use of ALD for Pt catalysts used in low temperature fuel cells. In particular, atomic Pt or clusters prepared by ALD show ten times higher methanol oxidation properties compared with ETK commercially-used catalysts [2].

In the second part, we will focus on employing ALD as a surface-modification method to enhance the performance of LIBs. Different materials for surface-modification (such as Al₂O₃, ZrO₂, TiO₂ and AlPO₄) [3,4] were first developed by ALD. Then systemic studies were carried out by using those materials to modify the anode (Li₄Ti₅O₁₂, SnO₂) [5] and the cathode (commercial LiCoO₂, NMC) [6]. The effects of different coating materials on the LIB performance of the anode and cathode were investigated in details. In addition, the potential application of ALD as a powerful technique for preparing solid-state electrolyte will be demonstrated [7]. We will discuss further development of ALD for fuel cells and Li ion batteries.
