Electric Vehicles and Hybrid EV's

Our commitment to advances in environmental technology

LiET are commercializing batteries for electric vehicles (EV) and batteries for hybrid electric vehicles (HEV). Both are types of AGDiB’s, but because battery requirements differ for EV and HEV applications, the materials, structures, and performance also differ. The batteries for EV use are designed as high capacity type batteries in order to extend the distance that can be driven on a single charge, while HEV batteries are designed as high output type batteries that can instantaneously transfer a large amount of power.


LiET’s High Capacity AGDiB Battery for EV Applications that Supports Rapid Charging

Electric vehicles are powered only by the energy that is stored in the on-board batteries.
Therefore, EV batteries must be designed as large capacity batteries so that vehicles can
travel long distances on a single charge. In addition, sometimes electric vehicles must be
charged away from home, so the batteries must be capable of being charged with a
rapid charger.

The cell capacity of LiETs AGDiB for EV applications is 100 mAh g−1 and a capacity
retention of 88% after 200 charge–discharge cycles.

Importantly, the volume energy density of the AGDiB can reach ~560Wh/L which is
much higher than traditional batteries (~350 Wh/L for Tesla Model S and ~200 Wh/L
for BYD E6). For example, a 500 kg, AGDiB-based power battery could reach a recharge
mileage of ~550 km (~425 km for Tesla Model S and ~225 km for BYD E6), and a 200
L AGDiB-based power battery could reach a mileage of about 560 km.

Compared with conventional LIBs, this battery (AGDiB) shows an obvious advantage in
production cost (~ 50 percent lower), specific density (~1.3-2.0 times), and energy density
(~1.6-2.8 times). This discovery is particularly important given rising battery demand and
existing LIB technology, which is reaching its limit in specific energy (by weight) and
energy density (by volume).


LiET’s High LiET High Output AGDiB Battery for HEV Applications

Hybrid electric vehicles (HEV) are powered by a combination of an engine and an electric motor. When the vehicle first starts to move and at other times when a large amount of torque is required, the battery pack and motor operate to assist the engine, and at other times, driving energy is recovered and used to charge the batteries. Therefore, emphasis is focused on performance that allows the batteries to instantaneously transfer a large amount of electric power.

LiET’s AGDiB for HEV applications are compact and lightweight and boast of an overwhelmingly high output.
