NOVELTY - Electrical current from generation plants (1, 2) is supplied for charging cells kept in charging stations (4) or depot stations. In accordance with need, these cells are taken out and used to operate transport units. On depletion, the cells are exchanged with charged cells at one or other of the stations. The energy generation plants are decentralized, being especially solar energy plants (1) and/or wind energy plants (2). Recharging current is delivered through a charging controller (3) of the charging station (4).    USE - A transportation system using rechargeable lithium-ion cells.    ADVANTAGE - The new transportation system is completely independent of fossil fuel sources of energy. Suitable, standard, commercially-available batteries are available. A tabulation of cell types, cathode materials, nominal voltages, capacities, cycling life and specific energy storage is provided. An area network extending over a country is illustrated. This allows large distances to be covered.    DETAILED DESCRIPTION - The lithium ion cells are charged, examined and tested before installation as energy storage units into the transport units. Discharged cells are exchanged, re-charged and stored in one of the charging stations. The distribution of depot stations allows replacement of cells before complete discharge. Spacing between individual charging stations and/or depot stations is 300-700 km. The lithium ion cells are combined into batteries. The voltage is 12, 24 or 42 V and the nominal capacity is 25-500 Ah, preferably 25-60 Ah. The electrochemically-active cathode material in the cells comprises: heavy metal oxides interleaved with lithium or preferably Li-Fe or Li-V-phosphate. The electrochemically-active anode material is synthetic or natural graphite interleaved with lithium. The anode/cathode separator is an electrolyte-containing, porous polyolefin-, polyfluoro- or ceramic layer. This is 10-40 mu m, preferably 5-25 mu m in thickness.
