Nanofibers offer key innovations in battery separators - thinner and ligher membrane, improved safety. New improved nanofiber separator NAFISEP will lead to advanced high capacity batteries and offer significant benefits to electric vehicles (EV), thanks to nanofiber benefits including, for example, high efficiency and lightweight characteristics.

1. NAFISep
Fast and Efficient Energy

2. Introduction
Membrain Separator plays a key role in LIB.
It keeps the positive and negative electrodes apart to prevent
electrical short circuits, and allows rapid transport of ionic charge
carriers.
Companies are in the technology-race to produce “ideal”
microporous separator that gives optimal performance under all
operating conditions.

3. Introduction 10bn by
2015
Nanofibers have Greater Opportunities
in Li Ion Batteries (LIBs):
 due to rapid growth of Consumer electronics
 increasing interests for Electric Vehicles - The
global automotive Li-Ion battery market is
forecast to grow from USD 1.5 bn to USD ~10 bn
by 2015

4. Scientific & Technological
Concept
Nanospider
technology
With NanospiderTM
technology and “our know-how
in development & optimization”
in industrial-scale equipment
achieved NAFISEPTM a promising
microporous (< 0.5 µm)
nanofibers based separator for
LIB.
We also have the capability to
produce NAFISEPTM in various
sizes in a cost effective manner.

5. Key Innovations of the Application
Our NAFISEPTM possesses:
 Thin and light weight
 Zero shrinkage at higher
temperature
 Improved safety due to
membrane stability
 Efficient Ion transfer due to
better wettability

6. Overall Impact of the
Application
Significant
benefits to
EVs
 New improved nanofiber separator NAFISEPTM will lead to
advanced high capacity batteries and offer significant benefits
to electric vehicles (EV), thanks to nanofiber benefits
including, for example, high efficiency and lightweight
characteristics.
 Simplified manufacturing process to reduce the production cost
of NAFISEPTM that will facilitate partnership with leading
battery manufacturers to create the next generation of
batteries with increased reliability and performance and
dominate the market.

7. Target Market Size & Customer
Opportunity

opportunity
LIBs are predicted to dominate all
other technologies in the
portable battery application
market over the next 5-10 years
China: Chinese LIBs market to
nearly double to $9.2 billion in
2016. Over 130 million Electric
bikes are on Chinese roads (but
only about 4-5% are currently Li-
powered.
