The Enhancement of Lithium-Ion Batteries’ Capacity and Life with the Development of Lithium Ion Mobility Between the Layers of Titanate Based Electrodes, 2013-2016, supported by TUBITAK 1001 Program (Researcher: S. Alkan Gürsel; PI: A. Yürüm)
- Nano structured temperature resistant titania electrodes that have high charge-discharge capacities and durability have been developed for lithium-ion batteries.
- In order to increase the capacity of these materials further and to keep its high capacity for a longer period, the distance between the titanate layers will be increased.

Lithium-ion batteries are incredibly popular these days. You can find them in laptops, PDAs, cell phones and iPods. They're so common because they're some of the most energetic rechargeable batteries available.
Hydrogen is a clean and abundant fuel for 21st century energy but its storage is one of the key issues for the hydrogen based fuel-cell vehicles. Various carbon-based adsorbents have been investigated for the safe and efficient storage of hydrogen.
One of the keys to advances in energy storage lies in both finding novel materials and in understanding how current and new materials function.

Sabanci University researchers seek improvement of energy storage density by conducting studies in branches of high surface area and porous materials such as Graphene and MCM41/Zeolite. It also supports analytical approaches on the performance of storage technologies.
Intelligent Gravimetric Analyzer (IGA) is specifically designed as a versatile gravimetric analysis system to accurately measure gas sorption isotherms from vacuum to high pressure. The IGA system includes a conventional microbalance head (sensitivity, ± 1.0 μg) mounted in a stainless steel vacuum-pressure reactor.
