Computer Questions & Answers : What Is a Lithium Ion Battery?

A lithium ion battery is a rechargeable battery in which ions move through the anode and cathode during discharge, and in the reverse direction while charging. Learn about the use of lithium ion batteries in computers and cell phones with help from a computer and network administration specialist in this free video on lithium ion batteries.

What I'm trying to figure out is what an anode and cathode look like in something like an 18 volt 2.4ah (ampere hours I believe) lithium ion rechargeable battery. My curiosity comes from my desire to recharge it GHETTO style by rigging a bunch of 6 or 7 bolt phone chargers, merging them, then connecting the red (cathode) bundle to the cathode on my 18 Volt and the same for the anthode. But I'm only 95% sure that I know where they are and which is which. I think they're either…

[epicroque]

a) three plates of metal standing in a row, two closer together than the last one, and they intersect black plastic planes of plastic much smaller than then which actually form the base upon which the metal plates are embedded. From two of them, the outside ones, they each have extended arms of metal that emerge to cover the tops of two cylinders’, and one arm is shorter than the other.

The middle plane connects to nothing. Now either the outside place with the longer arm is the cathode and the other outer plane with the shorter extension is the anthode and the middle is the electrolyte, OR…

b) The cylinders themselves are the cathode and anode. If you know anything about this, I'd offer you a branch of olives or a bushel of figs, perhaps even a wreath of pine to wear about and boast of your great deed done for the troubled mind so rattled, exhausted he (me) am near fainting, or there’s even frankincense and Mir or something other seemingly demeaning and anachronistic gift.

[epicroque]

Although demeaning only because of its anachronistic context, but in its time, its contribution to whatever era’s zeitgeist was irreplaceable, and the spirit of the time for me, even in times before my own, is eternal. Because only the illusion of passing time is the catalyst for people’s minds to become dulled by what once fancied them, thereby causing them to exile the tenets and the slum itself of the ‘Past Times’.

[epicroque]

All this bittersweet waste I walk the high wire in my bouts of change deciding whether to fall left into the droves filing out of town, or to the right landing in a sea of something words can never explicate, not when it’s the future we’re concerned with. The great shifts and the terrible shifts all in order to make room to let in the beauty of increasing novelty, new beauties, change of all kinds.

[epicroque]

So I assure you, coming from me such gifts of another time would be my truest form of appreciation, not only of you, but of the interminable eras that never really die because they were never truly born. I apologize; anodes and cathodes really bring out the Lorca and Ezra Pound in me.
