Localization of battery materials
2001:Anode similar to MCMB
     2002: LiCoO2 and Electrolyte
     2003: PVdF and SBR
     2004: LiMn2O4 and Natural graphite
     2005: LiMnNiCo materials and Artificial graphite
     2006: LiFePO4
2007: Separator, Packaging film for Polymer Battery

1. 2 Localization of equipments
All the machine for Lithium ion batteries can be made in China
But some key equipments are still unsatisfied
5
Modification of production mode
Change hand operation into auto and semi-automation operation
Application of new manufacture technologies and processes
6
Internationalization of market
Homemade mobile phone equipped mainly with homemade Remarkable quality improvement batteries
More than 80% portable DVD equipped with homemade batteries
Many manufactures e the supplier of foreign customer such as Motorola, Nokia and so on
7
Production capacity growth quickly
There are more than 50 Lithium ion battery maker
More than 20 relative large scale factories with capacity over 100K cell per day
New factories are still in building up
panies enter China such as SONY,SANYO, LG.
中国将成为最大的电池制造基地

Current development trend (H5L4S3C2E1)
High capacity (energy density), High rate, High average voltage, High safety, High temperature properties
(High voltage: capacity above of cut off
or discharging platform or middle point voltage)
Long cycle life, Low temperature properties, Low self discharge, Low cost
 Super-large, Super-small, Super-thin
 Consistency, Customization
Environment friendly processing
