Memory effect has been confirmed in lithium-ion batteries.

Li ion memory effect

Litium ion battery memory effect

Professor Petr Novak, Head of the Electrochemical Energy Storage Section­­­­­­ of the Paul Sherrer Institute reports that the memory effect has now been confirmed in lithium-ion batteries. This work was published in Nature Materials. “The memory effect and its associated abnormal working voltage deviation have now been confirmed for one of the most common materials used as the positive electrode in lithium-ion batteries, lithium-iron phosphate (LiFePO4).”  This is going to have important ramifications in the electric vehicle (EV) market, particularly in the battery pack automobile aftermarket.  NuVant Systems will be examining charge discharge protocols to address balancing of lithium ion battery packs in light of the report by PSI.  Charge discharge protocols for lithium ion packs will not be similar to those for nickel metal hydride batteries.  Read more about this outstanding work at PSI.
