Technology Description:

Columbia University aims to modulate the cycling behavior of conventional Li-ion battery materials in a bobbin cell format. The team will optimize electrode compositions, properties, and dimensions with corresponding cell configurations using standard commodity Li-ion materials and established bobbin cell manufacturing techniques. These cells will be suitable for 4-hour charge, and cost profiles amenable to 8-to-16-hour discharge. The team will produce Li-ion cells capable of cycling for more than 10 years at a discharge duration of 8 to 16 hours and a levelized cost of storage under $0.05/kWh.

Potential Impact:

By combining existing materials with longer duration form factors, like the bobbin cell, Columbia University will accelerate the cost curves for Li-ion grid scale storage cells from Bloomberg New Energy Finance’s forecasted time of~$50/kWh in 2035 to 2025. These cells will be suitable for daily, long duration grid storage applications.

Security:

Bobbin cells produced using existing commercial Li-ion battery materials and processes are well suited for daily many-hour duration (4h charge and 8-to-16h discharge) grid storage applications.

Environment:

The new design will increase the amount of energy storage to enable more efficient and cost-effective use of renewable electrical energy generation.

Economy:

The new design combines a mature set of battery chemistries with a commercial cell form factor to produce a battery that can lower the cost of future long duration storage technologies.
