Nickel-Iron Battery/User's Manual

Discharge

• Dead discharge for years does not hurt the battery? [1]

Are they really good?

• Good jar experiment that one can try - [2] - mentions nickel (II) hydroxide and rust (Fe3O4 - Magnetite.)
• Comment from user - the Chinese versions suck - [3]
• P. II-27 says Lithium Hydroxide is used in small part in electrolyte [4]
• Cost of LiIon is down to $100/kwhr [5]
• Shit. Under deep discharge of 60-80%- Westinghouse is getting only 1600 cycles. So do they degrade like lead acid? Maybe not as bad, but nowhere near the 30 years of deep discharge. -II-28

Cost

• 3.2kg of nickel per 1 kwhr p. II-32 [6]
