![]() ![]() The lab’s research spans every aspect of battery development, from the breakthrough fundamental science of the Argonne-led Joint Center for Energy Storage Research, a DOE Energy Innovation Hub, to the Argonne Collaborative Center for Energy Storage Science, a cross-lab collective of scientists and engineers that solves complex battery problems through multidisciplinary research.Īrgonne researchers are also exploring how to accelerate the recycling of lithium-ion batteries through the DOE’s ReCell Center, a collaboration led by Argonne that includes the National Renewable Energy Laboratory, Oak Ridge National Laboratory, as well as Worcester Polytechnic Institute, University of California at San Diego and Michigan Technological University.įor another take on “Batteries 101,” check out DOE Explains. automotive fleet toward plug-in hybrid and electric vehicles, and enabled greater use of renewable energy, such as wind and solar power. battery manufacturing industry, aided the transition of the U.S. The most common cathode materials lithium-ion batteries arefor LiMO 2 materials, where the transition metal M can be nickel, cobalt, manganese, aluminum or combinations of those elements. Over the past sixty years, the lab’s pivotal discoveries have strengthened the U.S. The cathode materials used in EV batteries today are far from standardized. ![]() Department of Energy’s ( DOE) Argonne National LaboratoryĪrgonne is recognized as a global leader in battery science and technology. Since this cycle can be repeated hundreds of times, this type of battery is rechargeable. This provides the energy to keep your devices running. When you plug in your cell phone to charge the lithium-ion battery, the chemical reactions go in reverse: the lithium ions move back from the cathode to the anode.Īs long as lithium ions shuttle back and forth between the anode and cathode, there is a constant flow of electrons. Panasonic has developed new battery technology for the 2170 lithium-ion cells it produces and supplies to Tesla, a change that improves energy density by 5 and reduces costly cobalt content. Chemical reactions occur that generate electrons and convert stored chemical energy in the battery to electrical current. Combined with better heat dissipation, cooler batteries will extend device lifespans too. Compared with other secondary batteries, the working voltage of lithium-ion battery is higher, and there is no memory effect 5. The move to graphene could offer 60 or more capacity compared to the same-sized lithium-ion battery. When a lithium-ion battery is turned on, positively charged particles of lithium (ions) move through the electrolyte from the anode to the cathode. Ni-MH batteries have excellent low temperature performance, but because it requires precious metals as catalysts, which increase its production cost, Ni-MH have not seen extensive use. ![]() Lithium-ion batteries that power cell phones, for example, typically consist of a cathode made of cobalt, manganese, and nickel oxides and an anode made out of graphite, the same material found in many pencils. ![]()
