TED Talks 2012: Donald Sadoway — The missing link to renewable energy
Donald Sadoway is working on a battery miracle — an inexpensive, incredibly efficient, three-layered battery using “liquid metal."
Slow discharge of a LiFePO4 nanoparticle
Slow discharge of a LiFePO4 nanoparticle
At small currents, ordered stripes appear in a 100x100nm particle due to coherency strain.
Moderate discharge of a LiFePO4 nanoparticle
Moderate discharge of a LiFePO4 nanoparticle
At moderate current (I/I0=.01), phase separation is observed but with less ordering than at slow current.
Quasi-solid solution behavior in LiFePO4
Quasi-solid solution behavior in LiFePO4
Phase separation is suppressed as discharge rate is increased (I/I0=.03) and the critical current is approached. There is not enough time for complete phase-separation, and a quasi-solid solution forms.

Formation of {101} phase boundaries in a LiFePO4 nanoparticle
When a LiFePO4 nanoparticle is held at 50% state of charge, coherency strain leads to the formation of {101} phase boundaries. Phase-field simulation of a 500x500nm particle.
Formation of {100} stripes in a LiFePO4 nanoparticle
Formation of {100} stripes in a LiFePO4 nanoparticle
When a LiFePO4 nanoparticle is held at 50% state of charge and cracks and dislocations cause a loss coherency in the [001] direction, a {100} stripe morphology is formed. Phase-field simulation of a 500x500nm particle.
