Formulation and characterization of ultra-thick electrodes for high energy lithium-ion batteries employing tailored metal foams

- We have constructed ultra-thick graphite electrodes using 3D Cu foam up to 1.2 mm as current collectors.
- The electrode exhibits very good storage capability and cycling stability at rates lower than C/5 rate.
- We have designed a bipolar configuration cell to study the effects of thickness.
- We have constructed a 1.2 mm thick Al foam electrode with L333 as a cathode material.
- A full cell was assembled by combining the Cu foam graphite negative and Al foam L333 positive electrodes.
