Silicon anode specialist Nexeon, along with a couple of partners, has been awarded £7 million in Innovate UK funding for the SUNRISE project, which will develop battery materials based on silicon as a replacement for carbon in the cell anode Nexeon will lead the silicon material development and scale-up stages of the project, while polymer… Read more »
US Army partners with Brown University to study SEI on silicon anodes
The US Army Research Laboratory (ARL) and Brown University researchers have teamed up to study the solid electrolyte interphase (SEI) layer that forms on the anodes of lithium-ion batteries, with particular emphasis on experimental silicon anodes. The Army is working to replace its alkaline and nickel-metal hydride field batteries with Li-ion batteries. “The Army is… Read more »
Molecular pulley leads to silicon anode breakthrough
Silicon anodes are receiving a great deal of attention, as they can enable batteries to deliver 3-5 times higher capacities compared with current graphite anodes. Although silicon is abundant and cheap, Si anodes have a limited number of charge-discharge cycles – typically less than 100 times. Their volume expands enormously during each cycle, leading to… Read more »
Researchers make a major advance in silicon anodes
Current electrode materials such as graphite are able to stably adsorb only a limited number of lithium ions, an inconvenient truth that restricts capacity. That’s why researchers around the world are investigating semiconductor materials such as silicon as alternative electrodes. Bulk silicon is able to accommodate enormous quantities of lithium, but the migration of the… Read more »
