Researchers recently created and tested two different formulations for batteries that store renewable energy ; when the energy is later used, an electrochemical reaction converts industrial carbon dioxide emissions into a solid form that has the potential to be used in other products.
"The Transformation Energy Science and Technology, or TEST, initiative at ORNL is precisely the kind of effort needed to address climate change. We are excited that ORNL is investing in innovative ideas and approaches that can transform the way we think about storing energy beyond lithium-ion batteries and other conventional electrochemical energy storage systems," said Ilias Belharouak, an ORNL Corporate Fellow and initiative director.
Studying how the film formed helped researchers understand how to break it down again. They were intrigued to realize the battery could be reactivated, or prevented from deactivating at all, simply through operational changes in the charge/discharge cycle. Uneven pulses of charging and discharging prevented film buildup on the electrode.
Other ORNL scientists who contributed to the project include Marm Dixit, Mengya Li, Sabine Neumayer, Yaocai Bai, Ilias Belharouak, Anuj Bisht, Yang Guang and former ORNL researcher Rachid Essehli. The research was funded through the ORNL Laboratory Directed Research and Development, or LDRD, program.

Researchers reveal oceanic black carbon sink effect driven by seawater microdropletsPyrogenic carbon is widely produced during the incomplete combustion of biomass and fossil fuels on land. About one-third of pyrogenic carbon is exported to the ocean by rivers, and thereinto, the refractory fraction becomes the source of oceanic black carbon that can provide a long-term sink for atmospheric CO2.

Researchers reveal mechanisms of soil organic carbon accumulation in acidified forest soilsSouthern forests contribute more than 50% of the soil organic carbon (SOC) in China's forest ecosystem, and the soil can still accumulate SOC. Deeply developed tropical and subtropical forest soil has undergone severe acidification, but the mechanism of continuous SOC accumulation in deeply acidified forest soils remains unclear.

Nanoparticle catalysts convert carbon dioxide to carbon monoxide to make useful compoundsAs a greenhouse gas, carbon dioxide (CO2) contributes to climate change as it accumulates in the atmosphere. One way to reduce the amount of unwanted CO2 in the atmosphere is to convert the gas into a useful carbon product that can be used to generate valuable compounds.
