Nanocarbon material (NCM), containing both the ordered carbon structures (carbon nanotubes (CNT), the particles of nanographite) and the particles of the disordered carbon phase, is known to be promising for using as elements of the nanodimensional devices and as fillers, for example, of lithium batteries. Structure and phase composition of NCM depend essentially on the methods of their obtaining and the regimes of the subsequent temperature and chemical treatment. Therefore, finding the correlation between the structural and phase composition and transport properties of NCM as well the description of the mechanisms of their conductivity are the important problems.

Inherently conducting polymers have also been used in polymer battery fabrication and an all-polymer battery structure has been developed [101a]. A specific charge capacity of 22 mAhg and a cell potential of 0.4 V were obtained. The cells showed no loss in capacity when cycled 100 times. Others have utilised conducting polymers as just one of the electrodes in a battery set-up [101b]. 

Steel electrode frame. The pocket plate follows a similar process. Rectangular pockets of perforated nickel-plated iron strips are filled with active material, crimped, closed, and fixed/bolted in a nickel-plated steel frame. The assembled cells are placed in polyethylene containers and filled with KOH electrolyte. Spacing of the negative and positive electrodes is maintained by the internal assembly structure. There are no separators as are common in the lead acid battery structure. 

Complete and detailed materials, parts and processes lists are provided to customers. A full traceability from raw materials for cell electrodes up to battery structure and components is always available. LATs (lot acceptance tests) are performed to check the qualification status. 

However the battery structure has changed substantially from initial ones. In the early days of lead acid batteries, the corrosion layers formed on the surface of lead sheet were used as active materials. But at present, the pasted type electrodes, which are made from lead-oxide paste and lead-alloy grid, are used generally. Then such pasted type electrodes are charged in sulfuric acid to make positive and negative plates and have much larger effective surface area which leads to larger capacity compared to the batteries of the early days. 

The aim of this study was to lead simultaneously a double approach, experimental and theoretical, to build a phenomenological model able to describe the data collected on positive electrodes (mainly LiCo02 and LiNi02). What is at stake is considerable isolating the relevant parameters that permit to describe and govern the interfacial mechanisms and more specifically the adsorption and insertion mechanisms. This will permit later on to stipulate the conditions of the optimization of the performances of the Lithium batteries (structure, morphology, interface, insertion rate, number of cycles, time, etc.).

The Li-ion battery is sometimes identified as Li-ion-manganese oxide (Li-ion-MnO). Essentially, the battery is made out of hthium and manganese oxide, whereas the Li-ion-polymer batteries are fabricated using lithium and polymer materials. Both the Li-ion-MnO and Li-ion-polymer battery packs are widely used by the EV and HEV manufacturers. The Li-ion-polymer battery packs can be easily damaged if not handled with extreme care. This particular battery pack requires outside walls made from high—mechanical strength material to protect the delicate control of IC circuits and battery structure [5]. The Li-ion battery packs have unique characteristics.

Inertial or setback activators are devices that are activated by a large-magnitude shock or rapid acceleration, as is generated upon firing of a morfar or artillery round. They are designed to react to a predetermined combination of g force and its duration. Inertial activators are typically firmly mounted inside the battery structure in order to withstand severe dynamic environments. 

Electrically rechargeable zinc/air batteries use a bifiinctional oxygen electrode so that both the charge process and the discharge process take plaee within the battery structure.
