The invention relates to a high-capacity
iron phosphate lithium power battery, which is characterized in that the
anode material uses the
iron phosphate lithium; an
anode current collector uses the
aluminum foil; a conductive agent uses the superconducting
carbon black and the conductive
graphite; the
anode material binder uses the polyvinylidene
fluorine; the
cathode material uses the
natural graphite or the artificial
graphite; the
cathode current collector uses
copper foil; the conductive agent uses the superconducting
carbon black and the conductive
graphite; and the
cathode material binder uses the polyvinylidene
fluorine or the
sodium carboxymethylcellulose and the
styrene butadiene rubber. The invention also discloses a
processing technology of the high capacity
iron phosphate lithium power battery, comprising the following step: matching ingredients,
coating, baking, rolling,
processing slice, baking,
staking, assembling upper cover , baking,
liquid injection, formation and partial volume. The invention adopts a stacking type, and has simple
processing technology, compact battery structure and stable performance; thus, the
battery capacity is greatly improved. The invention has an
advantage of providing the lithium
ion secondary battery of a driving
energy source to the small and medium sized electric tools, such as the household electric appliance, the
electric bicycle, the electric motorcycle and the electric automobile.
