Electrochemical energy storage device
An electrochemical energy storage device includes an anode having a first mixture which includes a first plurality of electrically conductive carbon-comprising particles having a first average porosity, and lithium metal materials. The weight ratio of the first plurality of carbon-comprising and lithium metal materials is from 30:1 to 3:1. A cathode includes a second mixture having a second plurality of electrically conductive carbon-comprising particles having a second average porosity greater than the first average porosity, and lithium-intercalating metal oxide particles. The weight ratio of the second plurality of carbon-comprising and lithium-intercalating metal oxide particles is from 1:20 to 5:1. The weight ratio between the lithium metal materials loaded in the anode and the second plurality of carbon-comprising particles in the cathode is from 0.1-10%. An electrolyte physically and ionically contacts the anode and the cathode, and fills the pore volume in the anode, cathode and a porous separator.
