CONCLUSIONS We have reviewed our study of the rocking-chair type cell based on the spinel Lit+xMn204 as the positive electrode and carbon as the negative electrode and discussed the critical factors involved in tailoring the electrochemical properties of these materials.
1. Introduction Rocking chair batteries (RCBs), in which only a specific ionic charge carrier in the electrolyte "rocks" between the positive and negative intercalation electrodes (Fig. 1 a), has been intensely studied since the discovery of intercalation materials in 1972 [1, 2].
In general, these cells have an energy density 2.5 and 1.5 times greater than Ni-Cd and Ni-MeH, respectively. Among the three potential rocking-chair systems, the Li-Mn-O based system is the most attractive in terms of cost. This factor will predomi- nate when larger size batteries will be made.
The electrolyte behavior of rocking-chair cells using the composite graphite electrodes over several cycles is depicted in Fig. 14. After the first five cycles, the cell maintains its capacity over subsequent cycles. Because of the higher ratio (2.8 instead of 2.1 when petroleum coke is used), the cell capacity is increased by 22%.
This review covers the basic study on the rocking chair LIBs regarding the charge storage mechanism across the principal battery components of the anode, cathode, and electrolytes, including the redox reactions and mass transports at the interfaces.
In spite of the low rate capability, the 50% loss during the first cycle is not tolerable with the present rocking-chair technology, because the amount of available lithium is defined by the amount of Li in the positive electrode. Thus, electrolytes that are compatible with graphite are needed.

The air-stable cathode and anode materi-als boosted the large-scale production to initiate the commer-cialization and thus the current form of rocking chair LIB was born in 1991.

It has been proposed in the late 1970s by Armand who suggested to use two different intercalation compounds as a positive and negative electrode, in the so-called rocking-chair battery, the lithium ions being transferred from one side to the other . Practically they were demonstrated in the early 1980s .
