In today's AFR, you can read that AGL is now going to offer solar energy storage systems to households
after teaming up Sunverge Energy of the U S ( with a Qland office ) ..these batteries are lithium powered.
These systems are going for between $15-19,000 but the through the Australian Govt ARENA ( Renewable Energy
initiative , ) I believe they are offering a subsidy
This is a good development for lithium usage and lithium stocks ...see the link below
