Abstract
ABSTRACT: Giner, Inc. (Giner) proposes to use its 5-V battery materials to provide the desired cycle life and specific energy for this application. The cell uses electrolyte combinations of selected cosolvents to reduce or eliminate carbonate solvents for greatly improved electrochemical stability to enable cycling over a significantly wider voltage range of between 5V and 3V vs. 4.1V and 3V for currently lithium ion satellite batteries. The higher voltage stability is further enabled by the use of a high voltage cathode material, which is synthesized at Giner. This cathode material offers exceptional cycling life capability because of its wide voltage range, resistance to metal dissolution and favorable structural stability during lithium insertion/de-insertion. The wide range of potentials will permit the optimization of the charge and discharge limits to achieve large increases in cycle life, without resorting to very low DOD. Cathode composition will be optimized to demonstrate the trade-offs between energy, power and cycle life for advanced space energy storage. Cell-level cycle life testing will be used to predict the improvements in cycle life using these materials while maintaining>200 Wh/kg specific energy with the necessary capacity retention on extended storage. BENEFIT: The proposed cell development will enable the development of large lithium-ion batteries with improved energy and power density as well as improved consumer and device safety in large cell arrays used in electric vehicles. Improvements in cell power will permit wider application of lithium-ion batteries and cells in portable consumer devices.
