3rd webinar of the IESA Knowledge Series on ‘Advanced Li-Ion Technologies (LTO, Li-Air, Li-Sulphur) and Emerging Opportunities’

The theme of the Webinar:  Battery energy storage systems have gained increasing interest in the world of electricity and mobility market. Lithium-ion batteries have evolved rapidly with a wide range of cell technologies and system architectures available on the market. Lithium is the lightest of all metals, it has the greatest electrochemical potential and provides the largest specific energy density. Due to its high energy density, long cycle life, better performance and high thermal safety Li-Ion batteries have become the most promising and fastest growing battery technology in the market. The First Commercial Li-Ion Battery was introduced by Sony in the year 1991 on Lithium cobalt oxide (LiCoO2) or LCO. Over the years, Lithium battery evolved with years from LCO, LMO, LFP, NCA, NMC and emerging technologies like LTO, Li-Air, and Li-Sulphur.

About Lithium Sulphur Battery:

• Lithium sulphur batteries are very attractive due to their 4-6X higher energy density compared to Li-ion batteries. The sulphur which is the cathode material is an abundantly available resource (no mining required). Its capacity is 8x higher than conventional Li-ion cathodes. The energy density of commercial devices is already 2X higher than current Li-ion batteries. The major challenge in LiS batteries is that the sulphur in the cathode is soluble in the electrolyte. Due to this, the capacity of the battery decreases rapidly with cycling. It has a high potential for usage like unmanned aerial vehicles (UAV), Space exploration – Satellites and interplanetary missions, Medical devices including external, implantable and portable devices, portable and wearable electronic devices.

About Lithium-Air Battery:

• Lithium-air batteries have an energy density comparable to gasoline which makes them attractive for Electric Vehicles. They are so lightweight because they do not have a cathode inside the battery. Instead, they rely on the oxygen that is present in air as the active cathode. Currently, the cycle life of the batteries needs to be improved so as to enable practical applications. Another challenge is the performance at high c-rates needs to be improved.                              

About Lithium-Titanate Battery:

• Lithium Titanate battery benefits range from a long lifetime to enhanced safety, low-temperature performance and large potential for electric vehicle space. Its applications persist in aerospace applications, electric transportations.

The objective of the webinar: To know more about the future of Advanced Li-Ion Technologies.
