Cracked cathodes not all bad, battery scientists find
Scientists developed an innovative method to observe the inner workings of lithium-ion batteries and found that cracks which form in the electrode, something manufacturers do their best to minimize, may actually have benefits in allowing for faster charging.
Carbon-cement supercapacitors for bulk energy storage
The Massachusetts Institute of Technology (MIT) has developed a scalable bulk energy storage solution with chemical with inexpensive, abundant precursors: cement, water, and carbon black. Their supercapacitors have high storage capacity, high-rate charge-discharge capabilities, and structural strength.
New technique to recover lead in end-of-life solar panels
A research group at Arizona State has developed a process to recover lead in its metallic form so that it can be reused in the PV industry. The process relies on a leaching solution based on a combination of acetic acid (CH3COOH) and hydrogen peroxide (H2O2), which the researchers said leaches the lead ‘in a matter of minutes.’
Sunnova to participate in battery emergency program in Puerto Rico
Distributed solar and storage customers sign up with Sunnova to participate in the Flex Power Program. By compensating customers for the power supplied by their batteries, they are incentivized to participate in the program designed to provide energy that reduces strain on the grid and minimizes blackouts at critical times.
