Natural flake graphite has become the dominant material for lithium-ion anodes as synthetic graphite’s market share dwindles.
Manufacturers have historically used the more expensive synthetic option because of its consistency, but natural flake’s popularity is growing in the industry due to its intercalation effect.
Industry experts are currently testing a proprietary technology that could make the production of graphite for lithium-ion anodes cheaper and easier.
Canadian minerals firm Elcora Advanced Materials claims to have developed a method of graphite manufacturing that reduces or eliminates the need for spheronisation, purification and coatings.
US chemical company Ashland has developed a water-based binder for high-capacity silicon-based anodes in lithium-ion batteries.
The Soteras™ MSi anode binder can be used with silicon to increase the capacity of lithium-ion batteries by as much as 30%, claims the Kentucky-based firm.
