Electrochemical Cells

HideShow resource information
Describe the Non-rechargable cell
Zinc-copper cell; Hydrogen gas oxidises to water to prevent build up of pressure; Ammonia dissolves to water of paste; Zn used up = canister thing = leakage
1 of 6
Describe the lithium ion
Used in mobile phones/laptops; Light; Polymer electrolyte = no leakage
2 of 6
Describe rechargeable batteries
Lead-acid batteries; Operate starter motor of car; Reactions reversed = electrons flow in opposite direction
3 of 6
Describe portable batteries
Nickel/Cadium; Expensive to buy; Recharged up to 500 times; Left to right = discharge; Right to left = charge
