Description
Technical field
The present invention relates to a kind of charging method, device and charging device, especially a kind of charging method, device and charging device that can adapt to polytype battery.
Background technology
Term " rechargeable battery " has implication well known in the art, generally refers to the chargeable battery that charging times is limited.The rechargeable battery be most widely used at present is Ni-MH battery and lithium battery.
Ni-MH battery refers to the battery of hydrogen ion and metallic nickel synthesis, and " metal " part in Ni-MH battery is actually metal hydride.Be used in the manufacture of Ni-MH battery, metallic nickel is mainly divided into two large classes.Modal is AB5 mono-class, A be rare earth element mixture (or) add titanium (Ti); B is then nickel (Ni), cobalt (Co), manganese (Mn), (or) also have aluminium (Al).The electrode of " containing the Multiple components " of some high-capacity batteries is then formed primarily of AB2, here A is then titanium (Ti) or vanadium (V), B is then zirconium (Zr) or nickel (Ni), adds some chromium (Cr), cobalt (Co), iron (Fe) and (or) manganese (Mn).That all these compounds are played the part of is all identical role: reversibly form metal hydride.During battery charging, the hydrogen ion (H+) in potassium hydroxide (KOH) electrolyte can be released, and it is absorbed by these compounds, avoids the formation of hydrogen (H2), to keep pressure and the volume of inside battery.When the cell is discharged, these hydrogen ions just can get back to the old place via contrary process.
During charging:
Positive pole reacts: Ni (OH) 2+OH-→ NiOOH+H2O+e-
Negative reaction: M+H2O+e-→ MH+OH-
Overall reaction: M+Ni (OH) 2 → MH+NiOOH
