Advanced Battery Technologies

The U.S. Army seeks partners to co-develop, license and commercialize battery innovations to improve energy density, cycle life, energy transfer, temperature range, and safety. These innovations include enhancements to electrodes, electrolytes, and even circuit breakers The U.S. Army Research Laboratory's (ARL's) Sensors and Electron Devices Directorate (SEDD) has developed and patented a number of inventinos related to batteries and capacitors. Examples below represent some of ARL's available technologies addressing the DoD's growing need for innovative power and energy solutions. Electrolytes For Next Generation 5V Li-ion Batteries. This drop-in technology enables at least 300 cycles at 5V, increases 4V cycles 50-100%, and is easy to produce. Electrolyte Formulations for Wide Temperature Li-Ion Batteries Increases operating temperature upper limit by 25% from 60 degrees Celcius to 75 degrees Celcius and beyond the minimal performance loss. Better Performing Lithium/Carbon Fluoride Battery. Eliminates voltage delay and conserves capacity in Li/CFx battery cells. Pure LiBOB Salt and Purification Process. Produces pure LiBOB salts that are thermally stable for high temp environments such as hybrid electric vehicles. High Voltage, Safer Lithium-Carbon Fluoride Battery. Safer method of manufacturing and higher running voltage and smaller voltage delay, as compared to Li/CFx batteries on the market today. Producing a New Class of Composite Cathodes for Li-Ion Batteries. Enables a new family of cathodes for less expensive, safer, and more environmentally benign secondary batteries. A full list of the technologies can be found in the Word Document below. Status and Opportunity: U.S. patents and patent applications available for license from the U.S. Army Research Laboratory. Other partnering and collaborative development opportunities such as CRADAs may be available with ARL researchers.
