HAND HELD SLO FOR OCULAR IMAGING AND VISION ASSESSMENT

Not Available MaxPower is proposing a Phase I program which is an integrated approach towards developing a high capacity-high rate Li-ion cell capable of operation from ambient temperatures to -40 degrees Celsius. Since all lithium intercalated into the anode of a Li-ion cell comes from the cathode, decreasing anode irreversible capacity and increasing reversible capacity will be much more effective with simultaneous increases in cathode capacity. This is MaxPower's integrated approach which involves three tasks. Task 1 involves R&D on anode materials starting with commercially available MCMB and Superior Graphite carbons. Pyrolyzed PAN-based carbon will also be investigated. This material is deemed to be a cost-effective substitute for MCMB carbons. Task 2 involves R&D on nanoscale size LiCoO2 with inert ceramic materials synthesized by a sol-gel method. The method allows for uniform mixing of active and inert materials and will facilitate Li+ ion transport across grain boundaries. The structural improvements in these composite cathodes will also enable at least 15 % more capacity to be obtained from LiCoO2 cathodes. Task 3 involves building, testing and delivery of both liquid and polymer 100 mAh Li-ion pouch cells. These cells will have energy and power densities exceeding, respectively, 100 Wh/kg and 40 W/kg, and will deliver useful capacities at temperatures down to -40 degrees Celsius.
