Li-ion battery waste used in biodiesel production from discarded vegetable oil

Green Car Congress

Brazilian researchers have demonstrated a new chemical approach for producing biodiesel from domestic cooking oil waste by using lithium hydroxide mixed with either sodium hydroxides or potassium hydroxides as catalysts. Before, in practice, these were just restricted to sodium hydroxide and potassium hydroxide.

ARPA-E awards $42M to 12 projects for advanced EV batteries; EVs4ALL program

Green Car Congress

The US Department of Energy (DOE) will award $42 million to 12 projects to strengthen the domestic supply chain for advanced batteries that power electric vehicles (EVs). Combining the TMCT with a high ion conducting solid-state electrolyte will enable rapid charging at ambient conditions. Award amount: $3,198,085).

U Alberta team develops hybrid sodium-ion capacitor; intermediate in energy & power between ultracaps and batteries

Green Car Congress

A team led by researchers from the University of Alberta (Canada) Scientists has developed a hybrid sodium-ion capacitor (NIC) using active materials in both the anode and the cathode derived entirely from peanut shells—a green and highly economical waste globally generated at more than 6 million tons per year.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Schematics of Li + /Na + mixed-ion battery. Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. During charging (or discharging), the storage (or release) of Li + takes place at anode, and the release (or storage) of Na + occurs at cathode. Chen et al.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

The economic benefits of recycling Li-ion batteries are clear, but at present, only a small percentage of them are recycled. In contrast, lead-acid batteries have a 99% recycling rate in the US. The two main processes for recycling lithium-ion batteries are pyrometallurgy and hydrometallurgy.
