Charge capacities

Figure 1. Charge and discharge curves of an Li/LiCoO, cell at a rate of 0.17 niAcm 2 at 30 °C. The cell was discharged to 2.5V, after a constant-capacity charge at 125 mAhg based on weight of LiCoO,.

The usual transportation tariff formula includes first, a capacity charge that gives booking rights for a certain capacity and secondly, a variable part charged per unit of gas actually transported, in order to cover variable costs. 

Schmickler [131] proposed a jellium model for the metal where the dielectric film in the solvent was replaced by a planar lattice of dipoles, with each dipole taking up one of three orientations. His calculated capacity-charge curves for different metals all exhibited a pronounced hump with a maximum practically at the pzc.

Analytical applications of electrochemistry, where the objectives are well defined, have fared better. There is a long list of papers going back twenty years on the applications of computers and then microprocessors. Reviews of this subject appear in the Fundamental Reviews sction of Analytical Chemistry (see refs. 8 and 9). In general, the aim in electroanalytical methods is to avoid interfering effects, such as the ohmic loss and the double layer capacity charging, and to use the Faradaic response peak current-potential curve as an analytical tool. Identification of the electroactive species is achieved by the position of the response peak on the potential axis and "pattern recognition , and quantitative analysis by peak shape and height. A recent development is squarewave voltammetry [10].

However, gas offtake regulation by the customer continues to be a problem. When determining actual capacity offtakes, an exact heat volume dispatching is of cracial importance, in particular in view of the very high capacity charges.

The secondary battery should satisfy as many of these requirements as possible in order to obtain good capacity, charging and discharging eflS-ciency, charging and discharging cycle performance and storage characteristics.

The equilibria of the electrode reactions are normally in the discharge direction since, thermodynamically, the discharged state is most stable. The rate of self-discharge [loss of capacity (charge) when no external load is applied] of the lead-acid cell is fairly rapid, hut it can be reduced significantly by incorporating certain design features.
