How the Grid Storage Launchpad is Accelerating EV Research
PNNL's new energy storage facility now houses the Lab's vehicle battery research programs, which have more lab space and a slew of new capabilities.
Xiao Receives Young Researcher Award
PNNL’s Jie Xiao was recently recognized for her outstanding contribution to basic and applied research on lithium-ion batteries and beyond by the International Automotive Lithium Battery Association.
Longer Lasting Sodium-Ion Batteries on the Horizon
A new longer-lasting sodium-ion battery design is much more durable and reliable in lab tests. After 300 charging cycles, it retained 90 percent of its charging capacity.
More Range for Electric Vehicle Batteries on the Horizon
A seemingly simple shift in lithium-ion battery manufacturing could pay big dividends, improving electric vehicles’ ability to store more energy per charge and to withstand more charging cycles.
BCI 2024
PNNL is presenting bold breakthroughs and insights at the BCI 2024 Convention and Power Mart Expo, celebrating Battery Council International's 100 years of leadership and the future of energy storage.
Electrolyte 'Boost' Improves Performance of Aqueous Dual-ion Batteries
PNNL formulated a new type of dual-ion cell chemistry that uses a zinc anode and a natural graphite cathode in an aqueous—or “water-in-bisalt”—electrolyte.
Kerry Meinhardt
Kerry Meinhardt’s research in solid oxide fuel cells has benefited the U.S. Navy. He and his team collaborated with Delphi Corp. to develop cost-effective solid-oxide fuel cells which are used in Delphi-developed auxiliary power units for t
HIGH CAPACITY AND STABLE CATHODE MATERIALS
High energy density cathode materials, such as LiNixMnyCozO2 (NMC) cathode materials, with improved discharge capacity (hence energy density) and enhanced cycle life are described, A solid electrolyte, such as lithium phosphate infused inside of secondary particles of the cathode material demonstrates significantly enhanced structural integrity without significant or without any observable particle cracking occurring during charge/discharge processes, showing high capacity retention of more than 90% after 200 cycles at room temperature. In certain embodiments the disclosed cathode materials (and cathodes made therefrom) are formed using nickel-rich NMC and/or are used in a battery system with a non-aqueous dual-Li salt electrolytes.
