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.
