energy stored devices & technology

1. Created by,

2. A Cell Or Connected Group Of Cells That Converts
Chemical Energy Into Electrical Energy By Reversible
Chemical Reactions And That May Be Recharged By
Passing A Current Through It In The Direction Opposite
To That Of Its Discharge – Called Also Storage Cell.
THE BATTERY

3. HISTORY/BACKGROUND

4. TYPES OF BATTERIES
The primary battery
The secondary battery

5. The secondary battery must first be charged with electrical
energy before it can convert chemical energy to electrical
energy . It is rechargeable.
Example-Lead Acid Battery
The primary battery converts chemical energy to
electrical energy directly, using the chemical materials within
the cell to start the action. It is not rechargeable.
Example-Dry Cell
THE PRIMARY BATTERY
THE SECONDARY BATTERY

6. Uses An electrolytic paste.
The electrolytic paste reacts with
the electrodes to produce a
negative charge on one
electrode and a positive charge
on the other.
The difference of potential
between the two Electrodes is
the output voltage.
DRY CELL

7.  A Hard plastic container.
 Positive and negative internal plates made of
lead.
 Plate separators made of porous synthetic
material.
 Electrolyte, a dilute solution of sulfuric acid
and water, better known as battery acid.
 Lead terminals, the connection point between
the battery and whatever it powers.

CELLS

9. Series circuits, the total voltage is
equal to the sum of the individual
voltages. The current is constant.
Parallel circuits, the voltage is
constant. The current is equal to the
sum of the individual currents
OHM’S LAW
R=V/I

10. SERIES CONNECTED BATTERIES
a. Positive terminal of one
cell is connected to the
negative terminal of the
next, is called a series
connected battery.
b. The voltage of this type
of battery is the sum of a
individual cell voltages.

11. PARALLEL CONNECTED
BATTERIES
o Connect the negative
terminal from one cell
to the negative of the
next cell
o Connect the positive
terminal to the positive
terminal, is parallel
connected.
o Voltage remains
constant and the
current is cumulative.

12. Negative plate reaction:
PbSO4(s) + H+(aq) + 2-e → Pb(s) + HSO4(aq)
Positive plate reaction:
PbSO4(s) + 2H2O(l) → PbO2(s) + HSO4(aq) +
3H+(aq) + 2e
The total reaction can be written:
2PbSO4(s) + 2H2O(l) → Pb(s) + PbO2(s) +
2H2SO4(aq)
CHARGING

13. Negative plate reaction:
Pb(s) + HSO4(aq) → PbSO4(s) + H+(aq) + 2-e
Positive plate reaction:
PbO2(s) + HSO4(aq) + 3H+(aq) + 2-e →
PbSO4(s) + 2H2O(l)
The total reaction can be written:
Pb(s) + PbO2(s) + 2H2SO4(aq) → 2PbSO4(s) +
2H2O(l)
DISCHARGING

14. • Clean Battery Terminals.
• Attach clamps to the battery in
proper polarity.
• Keep open flames and sparks away
from battery.
• Ventilate the battery well while
charging.
CHARGING

15. WHY ADD ELECTRONICS TO
BATTERIES?
REQUIRED ELECTRONICS ON NEW CHEMISTRIES:
Energy density has increased with each advancement in chemistry making cells less
stable.
Requiring:
– Safety circuits
– Cell balancing
– Secondary safeties

16. Added Value
Electronics:
Wireless Power (charging)
Using the Qi (inductive power
standard),Epec can embed
wireless charging electronics
in your battery to work with
off-the-shelf wireless charging
Pads that already exist, or
develop a custom pad for your
product.

17. BUILD TO PRINT ELECTRONICS

amount of space and
consumes more weight.
 researchers show interest
in Ultrathin, Flexible ,
safe energy storage
device.
 Nano scale.
INTRODUCTION

19. CARBON NANO TUBES
 A carbon Nanotube is a tube-
shaped material, made of carbon,
diameter measures on the
nanometer scale also known as
Bucky tubes.
 A nanometer is one billionth of the
meter.
 Carbon Nanotubes have many
structures, differing in length,
thickness, and in the type of felicity
and number of layers.
