Already responsible for changing the way we communicate and power portable devices, lithium-ion technology is now driving revolutions in both transport and energy supply the world over. A new paper published by Arumugam Manthiram of the University of Texas at Austin examines the technology’s development, from initial discoveries made in the 1970s to the considerations of today’s researchers working on the ‘batteries of the future’.
The U.S. conglomerate plans to deploy and test new controls with its commercial PV LV5 inverter platform. It aims to develop “grid-forming” controls to allow wind and solar inverters to form voltage and frequency levels like traditional generators. The company wants to improve coordination and synchronization among multiple grid-forming resources, and is working on smart PV reserve controls to improve the transient stability of systems with high renewables penetration.
Is there any good reason for putting solar on a Tesla Cybertruck? Or is it just virtue signaling? On the other hand, how far are you driving tomorrow? Do you have range anxiety or just general anxiety?
The Swiss equipment supplier already needed to shore up its bottom line and is now taking measures to help combat the spread of an epidemic which has also claimed November’s planned climate summit in Glasgow and an estimated 19% of this year’s demand for energy storage.
Scientists in the United States have developed a carbon nanotube method of fabricating a lithium-ion battery with a silicon anode. The device reportedly demonstrated better than 87% capacity retention after 1,500 cycles. The developers say their discovery overcomes many of the obstacles to the use of silicon as an anode and could open up the use of other materials for electrodes in lithium-ion devices.
The U.S. solar panel manufacturer has filed a lawsuit against Canadian Solar in the Federal District Court for the Northern District of California.
Scientists in the U.S. and South Korea have identified what could be a new route to high-efficiency perovskite-silicon tandem solar cells. Through engineering negatively charged particles in the passivation layer, the group made a tandem cell with 26.7% efficiency. With further tweaks to the silicon layer they expect to be able to surpass 30%.
Wood Mackenzie has cut its 2020 storage outlook to 430 MW – still an increase of more than 100% over 2019 – amid concerns over the role of sales, commissioning and interconnection in a period of shelter-in-place ordinances.
SunPower CEO: “We remain on track to complete our planned company split into two independently focused pure-play solar companies by the end of the second quarter.”
