The Li-ion market is growing but which Li-ion chemistries and technologies are going to be used?

At their most basic, Li-ion cells consist of an anode, cathode and electrolyte - the anode and cathode being largely responsible for how a cell performs. While various cathode materials are used commercially, only graphite is widely used at the anode. However, this may well be set to change. Silicon has garnered industry-wide attention due its ability to store 10x the amount of lithium compared to graphite. However, the material can expand up to 300% when charging, a major issue as it leads to low cycle life. As such, start-ups developing silicon anodes have received hundreds of millions of dollars in funding to find and scale solutions to this problem. And solutions do now exist, providing various opportunities for materials manufacturers. IDTechEx believe silicon dominant anodes will soon be utilised in mass market consumer devices before being rolled-out in the automotive sector later in the decade.
