Electrostatic engineering gets the lead out for faster batteries

"It's hard to see metastable things; even the theorists hadn't realized that bismuth ferrite could assume this form... What's beautiful about this material is the theory shows that strain alone cannot stabilize this antiferroelectric state. So this is a new knob," Schlom said... where you want to get the lead out. Antiferroelectrics are used in capacitors; it's already in thin film form. That makes our stacking approach to nullify the need for lead quite applicable"
