Abstract The paper discusses the newest technology for increasing the effectiveness of traction batteries for electric cars. It is achieved through the enhancement of already known chemical compositions used for the production of the anode, as well as through the introduction of new chemical substances and compounds. A significant accent is placed upon bringing down the battery charging time to several minutes. An increase in capacity, and thereafter the mileage. The improvement of these two parameters is shown to decrease the anode degradation and therefore increase battery life. The paper discusses batteries that use graphene-based nanocomposites, batteries using silicon and FLG girders and batteries using polymer rings and a new technology for lithium-sulfur batteries built of complex lithium-ion clusters. The battery uses variable resistance, which increases the electrolyte resistance when the battery reaches the lower levels of the critical temperature range and limits the current to safe levels. If necessary the resistance can be increased to interrupt the process (charge/discharge). After restoring the temperature to normal levels, the conductivity is restored without external interference.
