Red phosphorus is a potential anode material for lithium-ion and sodium-ion batteries, but like sodium itself, its positive values are counter-balanced by considerable challenges. Academics in China and Poland have done a detailed systematic review of phosphorus anode research, which has been published for anyone to read. “The development of cost-effective and high-performance red phosphorus anode materials for Li-ion and ...

500Wh/kg and 1,300Wh/litre from lithium ion cells
Amprius Technologies of California is claiming energy density of 500Wh/kg and 1.3kWh/litre from its latest demonstration of lithium-ion battery technology. This is about double the capacity of today’s general purpose cells. “The energy density performance was verified by [test house] Mobile Power Solutions. The results indicate that this cell model provides >504Wh/kg and >1,321Wh/litre at 25°C,” according to Amprius. This ...
Silicon anode material licenced from Nexeon
Oxfordshire silicon anode firm Nexeon has has licensed its NSP-1 material to Korean giant SKC, an investor in Nexeon. “Silicon-graphite hybrid electrodes are now delivering superior performance in hybrid and EV vehicles,” said SKC v-p Junghwan Shin. This arrangement follows the investment and strategic partnership announced between the two companies in January, and represents further income, said Nexeon: “The exclusive ...
Nexeon pulls in $80m towards silicon anodes for Li-ion cells
Oxfordshire-based silicon anode research company Nexeon has landed a $80m investment from a consortium including SKC, SJL Partners, BNW Investment and Kiwoom Private Equity. “SKC, a $5bn market cap company, is one of Korea’s leading advanced materials companies, with a strategic focus on rechargeable battery and semiconductor materials,” according to Nexeon. “Through this transaction, Nexeon enters into a strategic partnership ...
Another reason why Li-ion cells don’t like fast charging
Argonne National Laboratory has been looking into lithium-ion cells in great detail, and its scientists have found a nano-scale deterioration mechanism to add to the reasons that fast-charged Li-ion batteries degrade in electric vehicles. In use, lithium ions move in and out of the anode, which is usually made from graphite particles. The ions slide between the carbon atoms in ...
£1.5m for UK silicon anode li-ion project
Innovate UK has approved funding for the £1.5m ‘Silicon anode battery for rapid electrification’ (Sabre) project, intended to improve energy density in electric vehicle grade lithium ion batteries. The money, via Faraday Battery Challenge at UK Research and Innovation, will go to Nexeon, Britishvolt and University College London (UCL) to deliver Li-ion test cells with a silicon anode material. “Silicon has a ...
A route to practical silicon battery anodes?
Researchers at the University of Eastern Finland have combined mesoporous silicon microparticles, made from plant waste, with carbon nanotubes to improve the performance of silicon anodes in Li-ion batteries. “In the future, silicon will gradually replace carbon as the anode material in Li-ion batteries,” according to the university. “The capacity of silicon is ten times higher than the capacity of ...
Nexeon works towards silicon anodes for Li-ion cells with anode coating
Oxfordshire-based Nexeon is looking to improved anode surface morphology in silicon anodes for Li-ion cells, with the aim of improving anode conductivity for faster charge, and increasing cycle life. Its project, named Spice (silicon product improvement through coating enhancement), is with partners Phoenix Scientific Industries (PSI), AGM Batteries and Oxford University’s Department of Materials, and has been awarded £2m through ...
Has Norway discovered the X factor for silicon-Li-ion cells?
Norwegian researchers have discovered a way to stabilise silicon anodes for Li-ion batteries, according to the country’s Department of Energy Technology (IFE). Silicon anodes have the potential to far-exceed the lithium ion storage capacity of carbon anodes, if only they didn’t change size so much as they absorb the ions – as this physical swelling and shrinking quickly wrecks the ...
MIT spin-out proposes Lithium metal anodes for Li-ion
An MIT spin-out is preparing to commercialise a novel re-chargable lithium metal battery that it claims will double capacity.
