About Photovoltaic Energy StorageThree takeaways about the current state of batteries
About Photovoltaic Energy StorageWhile the word "battery" most likely evokes the chemical kind found in cars and electronics in 2023, hot rocks currently store ten times as much energy as lithium ion around the world, thanks ...
About Photovoltaic Energy Storage$begingroup$ Batteries have resistance, which loses energy in heat loss due to I2R dissipation. But supercat''s answer sort of touches on two other effects: (1) higher current use causes the battery voltage to reach its "end-of-discharge" voltage more quickly (you think it''s empty sooner than it actually is) due to IR drop, and (2) higher …
