CHIMERIC RIBOZYME FOR THERAPY OF PROLIFERATION VITREORET

Not Available MaxPower's Phase I program will develop new metal oxide anode materials with practical capacities> 500 mAh/g. The approach for this objective development of a Li-ion system containing a metal oxide anode which does not undergo significant irreversible losses during the first charging cycle. Task 1 involves R&D on anode materials starting with nanoscale sized pure Sn powders subjected to controlled levels of surface oxidation. This approach will minimize irreversible capacity losses by controlling the amount of li20 formed during the initial charging process. Task 2 involves R&D on Sn/Cu and Sn.Ni based alloys for anode materials in Li-ion cells. The objective of this approach is to eliminate the use of Sn oxide starting materials where all of the oxygen in the oxide is irreversibly converted to Li20. These alloys do not significantly expand and contract upon lithium insertion and removal which is of prime importance for high cycle life. The technology developed in tasks 1 and 2 will be transferred to Task 3 where prototype Li-ion cells will be tested and the results used to design and construct prototype 18650 Li-ion cells. BENEFITS: An expanded Li-ion cell technology base with respect to enhanced energy and rate capabilities, in general, and operability over the entire military range, in particular, will help push the Li-ion rechargeable batteries toward wide dual (military and commercial) market acceptance.
