Paper batteries offer a flexible and thin alternative to traditional batteries. They are constructed using carbon nanotubes coated onto paper. During discharge, lithium ions carry current between the positive and negative electrodes of lithium cobalt oxide and lithium titanium oxide coated on the paper. Paper batteries can power small devices and have applications in flexible electronics. They are lightweight, flexible and potentially lower cost than traditional batteries but further improvements are still needed before widespread commercial use.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

3. A paper battery is a flexible, ultra-thin energy storage and
production device formed by combining carbon nanotube with
a conventional sheet of cellulose-based paper.
A paper battery acts as both a high-energy battery and super-
capacitor , combining two components that are separate in
traditional electronics .
INTRODUCTION
4. WHY TO USE PAPER BATTERY?
Ultra-thin size & flexible structure.
Exhibits property of super-capacitor(22F-36F per gram)
Operating temper ature(-75 to 100 degree celsius)
provide both long-term, steady power production and
bursts of energy.
Cost-effective.
5. GENERAL Li-ION BATTERY
Generally Li-ion re-chargeable batteries are used in
mobiles,laptops and most of the electronic devices.
3 primary functional component of Li-ion battery are:
1. -ve electrode(graphite)
2. +ve electrode(cobalt oxide)
3.electrolyte( lithium salt in organic solvent)
During discharge and charging, lithium ions Li+ carry
the current from the negative to the positive
electrode and vice-versa respectively, through the
non-aqueous electrolyte .
6. Disadvantages of Paper Battery
• EXPENSIVE -- 40% more than NiCd.
• DELICATE -- battery temp must be
monitored from within (which raises the
price), and sealed particularly well.
• REGULATIONS -- when shipping Li-Ion
batteries in bulk (which also raises the
price).
Class 9 miscellaneous hazardous material
7. CONSTRUCTION OF PAPER BATTERY
CNT thin films were coated onto stainless steel (SS)
substrates with a solution based process.
The concentration of CNT is 1.7 mg/mL.
A dried film with a thickness of 2 micrometer was formed
after drying the CNT ink on the SS substrate at 80 °C for 5
min.This film is then peeled off from substrate.
These films act as electrodes of paper battery.
one film is pasted to electrolyte LTO (Li4Ti5O12) and the
other film is pasted to electrolyte LCO (LiCoO2).
Paper is sandwiched between two electrolytes LTO and
LCO with PVDF(poly vinylidene fluoride) acting as glue.
10. WORKING
2.Traditional Batteries produce electrons through a chemical reaction between
electrolyte and metal.
3.paper battery produces electrons due to the interaction of electrolytes LTO &
LCO.
4. Electrons collect on the negative terminal of the battery and flow along a
connected wire to the positive terminal during discharging.
5. Electrons must flow from the negative to the positive terminal for the
chemical reaction to continue.
1.While a conventional battery contains a number of separate components,
the paper battery integrates all of the battery components in a single
structure, making it more energy efficient.
11. Carbon nanotube is the main concept behind paper battery
Carbon nanotubes (CNTs; also known as buckytubes)
are allotropes of carbon with a cylindrical nanostructure. Allotropes
are different structural modifications of an element
CNTs exhibit extraordinary strength and unique electrical properties,
and are efficient thermal conductors.
Nanotubes are members of the fullerene structural family. The
diameter of a nanotube is on the order of a few nanometers Their
name is derived from their long, hollow structure with the walls formed
by one-atom-thick sheets of carbon, called graphene. These sheets are
rolled at specific and discrete angles, and the combination of the
rolling angle and radius decides the nanotube properties
CARBON NANOTUBES
15. Paper battery offers future power
The black piece of paper can power a small light.
Flexible paper batteries could meet the energy demands of
the next generation of gadgets.
The ambition is to produce reams of paper that could one day
power a car.
The paper battery was a glimpse into the future of power
storage.
16. • The flexible battery can function even if it is rolled up,
folded or cut.
•We can get 2.5 volts of electricity from a sample the
size of a postage stamp.
• "If we stack 500 sheets together in a ream, that's 500
times the voltage. If we rip the paper in half we cut power
by 50%. So we can control the power and voltage issue."
• Because the battery consists mainly of paper and
carbon, it could be used to power pacemakers within the
body where conventional batteries pose a toxic threat.
ADVANTAGES
17. DISADVANTAGES
•If inhaled it can also harm human being.
•Due to low shear strength these batteries can be
torn easily.
•Expensive and less efficient methods are used in the
manufacturing of carbon nanotubes.
18. CONCLUSION
A paper battery is a battery
engineered to use a paper-thin
sheet of cellulose (which is the
major constituent of regular
paper, among other things)
infused with aligned carbon
nanotubes
