A bio-battery is an energy storage device generating electricity from organic compounds like glucose, providing sustainable power. It consists of two types, a passive system utilizing natural diffusion and an active system using forced introduction of reactive substances. Bio-batteries have applications in powering low-consumption devices such as calculators and sensors, with advantages including instant recharge and high fuel flexibility.

2. WHAT IS BIO
BATTERY??
A bio-battery is an energy storing device
that is powered by organic compounds.
Bio-Battery generates electricity from
renewable fuels (glucose, sucrose, fructose,
etc) providing a sustained, on-demand
portable power source.

3. TYPES OF BIO
BATTERY
PASSIVE SYSTEM TYPE
A system in which reactive substances are
absorbed in to the electrodes through a
process of natural diffusion
ACTIVE SYSTEM TYPE
In this type reactive substances are
introduced by force by some means

4. FIRST BIO BATTERY
On August 23, 2007 Sony announced the
development of a bio battery that generates
electrical energy from carbohydrates using
enzymes as catalysts through the application of
power generation principles used in living

6. •Between the anode and the cathode lies the electrolyte which
contains a separator. The main function of the separator is to
keep the cathode and anode separated, to avoid electrical short
circuits. This system as a whole allows for a flow of protons
(H+) and electrons (e-) which ultimately generate electricity.
•Glucose is broken down on the anode side of the battery,
producing protons (H+) and electrons (e-). The protons (H+) are
transferred to the cathode side through the separator, while the
electrons (e-) are transported to the cathode side through the
mediator, which transfers them to the external circuit. The
cathode uses the enzymes to drive an oxygen-reduction reaction
which ultimately produces water using both the protons (H+)
and the electrons (e-) transferred from the anode. These
reactions at the anode and cathode generate electric energy by
creating proton (H+) and electron (e-) flow in the cell system.

7. BIO BATTERY TEST
CELL SPECIFICATIONS
• Dimensions: 39*39*39 mm
• Volume: 40 cc (without casing)
• Max Output: 50 mW

8. ADVANTAGES
• A significant advantage that bio-batteries have
in comparison to other batteries is their ability
to allow an instant recharge. In other words
through a constant supply of sugar, or glucose,
bio batteries are able to continuously keep
themselves charged without an external power
supply with high fuel flexibility like sugar,
alcohol, diesel, ethanol, blood etc

9. APPLICATIONS
• This device can be used to power
small/low power consuming
devices consistently over a long
period like calculators, and robotic
devices in remote areas and
underwater sensors.
