Metal-Oxides could give LiFePO4 a boost in storage capacity (one of their sorely lacking areas), as well as a dramatic impact on specific conductivity. If they can manage to turn this into actual batteries it would be a significant leap.
The breakthrough is from a company in Taiwan – Advanced Lithium Electrochemistry. They claim that by enhancing the cathode with a metal-oxide, it can dramatically improve the capacity as well as the power. The improvement increases the electroconductivity by seven orders of magnitude over pure LiFePO4 – from approximately 10E-9 to the 10E-2 S/cm range. Along with this improvement was an increase in battery capacity to over 400Wh/kg (3.3V and 130Ah/kg).
If brought to market anytime soon would provide a dramatic increase. Such a dramatic increase I’m pretty skeptical, but this was presented at a battery conference in Long Beach, CA so I’m somewhat confident that it isn’t totally made up. Even if it takes 5 years to get it to market, its a large boost over current and even prospective future batteries.
If and when they get to market, they would be an excellent fit for all BEVs.
