About Photovoltaic Energy Storage"Lithium is actually a soft material, but, like the water in the pothole analogy, all it takes is pressure to widen the gap and cause a failure," said Xu, a postdoctoral scholar in Chueh''s lab.
About Photovoltaic Energy StorageInteresting. I put a 120x under the bonnet in my landcruiser, and it ran faultlessly powering our fridge for 2years. I sold the car so it is probably still running fine. I definitely don''t like the "drop in replacement" line that they push. If you install a lithium battery you should have a lithium charge profile for the charger.
