Abstract :
In this work, the acetylene black and ammonium bicarbonate are co-doped in LiFePO4 by ball milling. When heating the sample in argon condition, the porous structure LiFePO4 doped with conductive agent can obtain after ammonium bicarbonate is decomposed. The material shows excellent cycle performance when fabricated a Li-ion half-cell. Such a cathode material may be a good candidate for three dimensional Li-ion batteries developed in the future.
