FIELD: electricity.
SUBSTANCE: batteries comprise an electrode carbon fiber structure according to the present invention and are characterized by an improved charge take up speed under dynamic conditions (DCA) and/or a current magnitude of cold cranking amps CCA and/or retains DCA with an increasing number of charge-discharge cycles. The volume ratio, which is important for the reaction rate, is the porosity of the electrode material and lead-containing particles. Such porosity is necessary, since it allows acid ions and Pb++ to diffuse to and from the reacting surface.
EFFECT: improvement of battery construction.
