Lithium ion moves from the negative pole (anode) to the positive pole (cathode) at discharge and vice versa.
Between the electrodes is a liquid chemical, an electrolyte, and a permeable membrane, separator that allows only ions to pass through.
According to Martin Reynolds, vice president of Gartner Research, one way to increase power capacity is to make the separator thinner and increase the chances that the walls will be penetrated. A Sony Corp. -
