Sandwich Like Arrangement的意思|示意

夹层似空间分配 The battery-maker’s dilemma is that the recharging rate depends on the area of contact between electrolyte and electrode. A thin, sandwich-like arrangement, in which cathode, electrolyte and anode are close together, can thus be discharged and recharged rapidly. However, this speed comes at a price. The amount of energy a battery can store depends on the volume of its electrodes, so a thin battery does not last long. What is needed is a way to increase contact area without sacrificing volume. And that is what Dr Braun has found. Moreover, his solution looks suitable for mass production.
