In this talk we will screen and present our activities in the arena of battery technologies. The talk will be diverse in its nature, spanning from understanding the solid electrolyte interphase (SEI) on Li and Li-ion anode materials and discussing the interfaces formed followed by the implementation of an artificial SEI construction, introduction of CNT tissues as current collector in Li-ion batteries, and ALD protecting coating on LMNO 5 V spinel cathode materials and to advanced rechargeable Si-ion batteries.

SEI model and advance model of the interface formed in a “sticky fingers” model will be discussed. CNT coated with thin copper film via an electrodeposition from different electrolytic baths serving as anode current collectors as well as metal fluoride coatings (from the Li-Mg-Al fluorides) will be demonstrated. An integration of these advance materials into a single cell will be presented.  In addition, the possible use of Si as an active anode in a rechargeable battery configuration will be discussed.
