Abstract
Non-aqueous solid electrochemical cells with improved performance can be fabricated by employing intercalation based carbon anodes comprising a mixture of carbon particles having different morphologies and selected from platelet-type, microbead-type and/or fiber-type structures. The anodes exhibit good cohesion and adhesion characteristics. When employed in an electrochemical cell, the anode can attain a specific electrode capacity of at least 300 mAh/g. The electrochemical cell has a cycle life of greater than 1000 cycles, and has a first cycle capacity loss of only about 5-15%.
