ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

The University of Texas at Arlington will develop acoustic stimulation and electrolytic proton production to produce lithium (Li) and nickel (Ni) from CO 2 -reactive minerals and rocks that contain calcium (Ca) and magnesium (Mg), while sequestering CO 2 in the form of carbonate solids.

Saft and ESMA to Cooperate on Supercapacitor Development, Production and Commercialization; Heavy Diesels First Target

Green Car Congress

The first results will be seen later in 2009, when Saft’s US manufacturing facility in Valdosta, GA begins production of a new generation of asymmetric nickel supercapacitors that will work in combination with batteries on heavy vehicles in a large variety of markets including, but not limited to, industry or public transportation.

New strategy for dendrite-free Li-metal batteries based on atomic channels

Green Car Congress

An international team of researchers has developed a new strategy for dendrite-free lithium-metal batteries based on the use of interlayer and intralayer atomic channels in graphite formed by pre-tunnelling the graphite layers. The obtained atomic channels enable the free and fast diffusion of lithium with enhanced kinetics. atomic channels.

The 80-20 Rule

Plug In Partners

Two reasons: (1) Electric motors are extremely efficient compared to internal combustion engines, and this efficiency more than compensates for the dirtiness of coal. (2) However, automakers would like to switch from NiMH to Li-Ion batteries for PHEVs because they are lighter, smaller, and potentially cheaper. 2) The U.S.

Researchers boost performance of lithium-rich cathode material 30-40% by creating oxygen vacancies

Green Car Congress

An international team of researchers has demonstrated a new way to increase the robustness and energy storage capability of a particular class of “lithium-rich” cathode materials by using a carbon dioxide-based gas mixture to create oxygen vacancies at the material’s surface. —Qiu et al.
