Market interest in silicon, lithium-metal battery anodes only growing - report - MINING.COM

Here are my favs in the article (emphasis added).....Hpq would appear to be at the right place at the right time with the right (and affordable) solution

“Incorporating porosity, electrolyte additives, and conductive and binding networks are just some of the solutions that are being developed,” the dossier states. “Silicon also has a reduced risk of dendrite formation, while the porosity and conductive additives that are generally needed further help with fast-charge capability and operation at low temperatures. Overall, silicon anodes represent a highly promising proposition and companies are now advertising cells with reasonable cycle lives, providing evidence that the key drawback of silicon is close to being overcome.”

Despite the challenges that still need to be addressed, for IDTechEx the key to the success of silicon and lithium-metal anodes is starting to shift toward how these solutions can be manufactured at scale and integrated into current battery manufacturing processes. 

“With similar advantages and disadvantages, ultimately, the question will not be about the use of silicon or lithium, but the implementation of a given innovation or solution,” the report concludes.
