Most commercial lithium ion batteries use graphite anodes, despite silicon anodes having 10-times greater energy density. The issue with silicon anodes is that they expand and contract as the battery is charging and discharging, making them too volatile for use in most products. The engineers were surprised to discover that they were able to overcome this limitation by removing the liquid electrolyte and replacing it with a sulfide-based solid electrolyte. The Engineers have created a brand new type of battery that could revolutionise the charging time and range of electric cars and other technologies reliant on lithium-ion batteries. Should the Covid-19 pandemic period be called a technology revolution period ?
