ABSTRACT

Gelatin-pretreated graphite particles were used to prepare anodes for use in lithium ion rechargeable batteries. The amount of adsorbed gelatin at various conditions is estimated using gravimetry and thermogravimetry. Electrochemical properties, such as irreversible loss of charge, reversible capacity and efficiency of gelatin-pretreated graphite anodes are compared to the properties of conventional graphitic anodes prepared using polymeric binders. A model explaining the different behaviour is presented. At the end, a preliminary testing of a full lithium ion battery prepared without use of conventional binders is shown.
