Abstract
Lithium electrochemical cells and batteries are described having electron conductive additives in the form of a mixture of carbon fibres and fine carbon particles. The electron conductive additives are provided in a polymeric fluoride coating between the electrode and the current collector. A mixture of carbon fibres and fine carbon can also be admixed with the cathode-active component in the cathode.
