lithum-ion is misspelled. Currently, five questions are tagged with this misspelled tag.

I propose two solutions:

Option 1: Burninate lithum-ion.

Just use the more general battery. Are different battery technologies too localized?

Option 2: Add tags for different battery technologies.

On the other hand, it might be useful to make tags like

• li-ion
• nimh
• nicd

After some browsing, I've seen multiple questions in which the question or answer is ambiguous because the battery chemistry isn't clear. (Lithium ion's needs are different from nickel-metal hydride's.)
