Due to their high energy density, lithium-ion batteries are used in many commercial electronic appliances. They are also believed to exhibit no memory effect. That’s how experts call a deviation in the voltage of the battery that can limit the usability of the stored energy as well as the ability to determine the state of charge of the battery reliably. Scientists at the Paul Scherrer Institute PSI, and the Toyota Central R&D Labs, Inc. in Japan have now however discovered a memory effect in a lithium-ion battery. This finding is particularly relevant for the use of lithium-ion batteries in the electric vehicle market.
