Slide 1

Batteries Physics

Slide 2

Power Cell Device for putting away synthetic vitality and afterward discharging it as power when current is required

Slide 3

Battery More than one force cell cooperating

Slide 4

9 V battery Inside a 9 V are 6-1.5 V power cells associated in succession.

Slide 5

Parts of a Power Cell 1. Anode Metal High proclivity for oxygen Draw oxygen from cathode to end up oxidized

Slide 6

Parts of a Cell 2. Cathode Metallic oxide Lower fondness for oxygen Becomes diminished when oxygen is taken

Slide 7

Parts of a Cell 3.Separator Insulator Keeps cathode isolated from anode to control response

Slide 8

Parts of a Cell 4.Current Collector Connected to anode and cathode Good transmitter 5.Electrolyte Usually fluid (ionized water, corrosive/base) "Domino Effect" of oxygen from cathode to anode

Slide 9

Operation of Power Cell As anode gets to be oxidized, an electron must be surrendered Electron courses through anode's ebb and flow gatherer  through circuit (outside of battery) as electrical ebb and flow  back to cathode's ebb and flow authority

Slide 10

Carbon-Zinc (C-Zn) 1.5 volts Works well if utilizing 100 mA or less Low limit 3 year time span of usability

Slide 12

Alkaline 1.5 V: lose voltage step by step High Capacity (electrical vitality) Last more 5 year timeframe of realistic usability Better in high deplete gadgets than C-Zn

Slide 14

Lithium Started off as catch cell Anode: lithium Cathode: magnesium dioxide 3 V: Takes up less space with more voltage

Slide 15

Lithium High Capacity Low Drain Rate Toxic: Special transfer Light Weight

Slide 16

Button Cell Anode: Zinc or Lithium Cathode: Silver or Mercury Oxide Compact Large Life

Slide 18

Recharging Batteries A momentum from an outside source is pushed through the cell the other way from the first ebb and flow Oxygen goes from anode to cathode

Slide 19

Nickel-Cadmium (Ni-Cd) 1.2 Volts Low limit Memory impact (Rechargeable) If you re-charge the battery too early, you bring down its ability

Slide 20

Nickel-Metal Hydride (NiMH) 1.2 V Best rechargeable battery High Capacity Good for high waste gadgets

Slide 22

Lithium-Ion 3.6 V Slow-loss of charge (5% every month) Best vitality to weight proportion No memory impact Popular for versatile hardware (phones, IPod)

Slide 23

Diode Made of semi-leading material Only allows ebb and flow to go in one bearing L.E.D.: light emanating diode Longer leg must be associated with positive side of circuit (cathode)
