Greetings !
I have a problem and I have no idea ! Spech is about electrochemical cell and graphene oxide/ metal oxide composite material as anode material for LJB. During cycle performance for first 50 cycles significant decrease of capacity was observed , but then it starts to go up and becomes more than it was at the starting point of cycle performance procedure....
performed cycle number was 100 about .
Perhaps, someone has any ideas why such thing happen ?
Whats going on with particular material ?
Thanks a lot before !

High Capacity MoO2/Graphite Oxide Composite Anode for Lithium-Ion Batteries
Maybe you can find some information from this paper.
Dear prof. Shen - MIng Chen , Thank yo very much for Your suggestion , I apreciate it !
Thanks a lot !

You may need to make more measurement to get more complete picture. Your graphic is similar to the one in this publication: http://cdn.phys.org/newman/gfx/news/hires/2013/1-holisticcell.jpg
The reason could be that it needs a couple of cycles to build a stable SEI?
