This document discusses bio-batteries, including their history, structure, working principles, advantages, and future potential. Bio-batteries use organic matter like glucose or enzymes to produce electricity through chemical reactions, avoiding the need for toxic materials. They have advantages like being quick to recharge, producing clean energy, and high safety. However, their energy yields and ability to retain energy are challenges. With further research and development, bio-batteries may become a reliable new source of energy.

2. OBJECTIVES
• Provide the specific details about bio battery
• Enrich the knowledge of types of energy, how to produce energy
• Make a comparison with others types of energy we learnt

3. OUTLINE
I. What is a bio battery?
1. Definition
2. History
II. How does it work?
1. Structure
2. Working of 2 main types
III. What are their pros and cons?
1. Advantages
2. Disadvantages
3. Future

4. WHAT IS A BIO-BATTERY?
• The substrate material, organic or
inorganic, compounds => electric
energy
• Enzymes, microorganisms => p + e
• Continuous circulation

5. Stacked Bio Battery

6. HISTORY
• 1912, the first microbial BFC
• 1964, the first enzyme-based bio-fuel
cell
• 2003, Bio battery using Human Blood
• 8/2005, Bio battery using Human
Urine

7. HISTORY
• 8/2005, Bio battery using Human
Urine
• 2007, Bio Battery using
Carbohydrates Sony Corporation
• July 17, 2013 ,Microbial fuel cell -
- MFC

8. HOW DOES IT WORK?

9. STRUCTURE
• Anode
• Cathode
• Electrolyte
• Mediator

11. • bio batteries are
heavily based on the
amount of glucose
avaible
• soda, waste materials
or the glucose in
living organisms
• protons and electrons
from glucose
GLUCOSE

12. GLUCOSE
- The process of enzymatic
hydrolysis.
- Cellulose (an insoluble
substance).
- Existing oxygen and other
enzymes - producing hydrogen
ions and electrons.

13. Process
 human bodies convert food to
energy using enzymes
 bio-batteries use enzymes to
convert glucose into energy.
Glucose
→ Gluconolactone + 2H+ + 2e−

14. process
• Electron and proton travel
through the electrolyte -
the separator redirects
electrons to go through the
mediator to get to the
cathode.
• O2 +4H+ + 4e− → 2H2O

15. ADVANTAGES OF BIO-BATTERY
Outstanding among chemical batteries:
Quick
recharging
capabilities
Clean, non-
toxic source of
energy
Extremely
safe

16. Potential of battery
Applications

18. DISADVANTAGES OF BIO-BATTERY
• actual yield of the battery
• Contamination: wrong
batteries
• ability of the bio battery to
retain the energy.

19. FUTURE OF BIO-BATTERY
• A new source of energy: bright
• a good reliable news source of
energy
• Sony:
- Research, make
- Lead the market
