Batteries

Primary Cell

Not reversilble, Zn anode, 1.5 V (Dry cell and Button Battery)

Dry Cell

Zinc anode, acidic or alkaline, hold charge for a long time, not rechargable

Button Battery

siver-zince, high storage capacity, very small, alkaline

Secondary Cell

Can be recharged (Lead acid, car batteries, NiCAD, Lithium)

Lead Acid(Storage Battery)

2V, Anode and Cathode= Pb and H2SO4

Car batteries

Lead Acid Battery, 6 cells (12V), Can’t start at low voltage because of decreased voltage, several years, 35% sulfuric acid.

NiCAD

Rechargeable version of dry cell batteries(AA,AAA), cordless electronic devices. Anode:Cd, Cathode:NI

Lithum Ion Cell

Anode:LixC6, Cathode:LiyCoO2, Extremely reliable, 2X the electronic capacity of NiCAD, smartphones, laptops

Flow/Fuel Cell

Anode: Hydrogen, Cathode Oxygen, very clean, extremely spontaneous
