Advantages
- High energy density - High energy efficiency - Rapid charge and discharge
- Long life - Low price - Resourceful (Na, S)
-Long life - Proven technology - Confirmed method of Recycling of the battery
- Rapid charge and discharge - Resistance to overcharge and over discharge
Disadvantages - Danger of Organic electrolyte
- Exothermic danger - Low energy density -High price of hydrogen storing alloy -Exothermic danger

Key Features of NEC’s Li-Ion Technology
▐ Manganese Spinel Cathode Material
Greater resistance to overcharge
and high thermal stability
Abundant material deposit
compared with Co and Ni
▐ Laminated Cell Structure
Low internal resistance and high
heat dissipation allows less heat
generation than a cylindrical cell
▐ Proven Reliability as a Large- Capacity Auto Batteries
Safety& Long Life of more than 100,000 km has been proven by Nissan’s HEV Test
Mass Production Quality has been achieved with Subaru Plug-in STELLA
