In the video, Bernard states that the Gen3 batter is partially optimized..Being curious, I ran this search about what can be done to optimize a silicon battery. While some of the below is probably already in the mix, I wonder what will be applied next (the bold text is mine...thinking that these may be next possibilities for added improvement short of adding additonal silicon to the batch...although prelithiation may already be in the mix)?  
_____________________________________________________
here are a number of ways to optimize silicon batteries, including: 
 
 
  • Use less of the silicon's capacity
    Silicon's high energy capacity means that using only a third or fifth of its capacity can still significantly improve battery life. 
     
     
  • Add a small amount of silicon to graphite anodes
    Adding 5–10% silicon to graphite anodes can increase capacity without causing the anode to break down too much. 
     
     
  • Make the silicon anode porous
    This allows the silicon to expand into the holes without disturbing the surface. 
     
     
  • Use prelithiation
    This priming strategy compensates for the lithium loss that typically occurs with silicon. 
     
     
  • Add MXene to silicon anodes
    This could extend the life of lithium-ion batteries by as much as five times. 
     
     
  • Use a multilayer carbon skeleton network and graphene
    This can help with the volume expansion and low electron mobility of silicon-based anode materials. 
     
     
  • Use a random terpolymer as an aqueous binder
    This can improve the adhesion effect and provide fast channels for lithium ion transport. 
     
     
Silicon expands as it charges, which can cause it to break and malfunction.
