Solid state Batteries v/s Li-ion Batteries: A Comparison Based on Cost

Get Electric Vehicle

  As for any novel technology, the cost to develop, manufacture and integrate remains one of the deciding factors in the mass adoption and acceptance of these technologies. To better understand the severity of the cost component, let us look at the cost comparison between Solid state and Li-Ion batteries.

Gel polymer electrolyte for stabilizing sulfur composite electrodes for long-life, high-energy Li-S batteries

Green Car Congress

In a paper in the Journal ChemSusChem they report that using a novel gel polymer electrolyte (GPE) enables stable performance close to the theoretical capacity (1675 mAh g -1 ) of a low cost sulfur-carbon composite with high active material loading, i.e. 70% S.

Stanford faculty awarded $2.2M for 9 energy research projects; high-performance batteries, promoting sustainable vehicles, wireless power transfer for moving vehicles

Green Car Congress

The Precourt Institute for Energy, the umbrella organization for energy research and education at Stanford, will fund the following four studies: Nanostructured Polymers for High-Performance Batteries. One way to lower the cost of solar power is to dramatically reduce the thickness of light-absorbing layers in solar cells.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

In addition, material sustainability is also a critical factor when considering the total economic and environmental benefits for grid-scale energy storage applications. Crucial to the idea of lowering the cost of battery materials, myo-inositol is an abundant organic compound familiar to industry.

CMU study suggests difficulties in reaching targeted low price points for Li-ion batteries

Green Car Congress

Their findings suggest that prismatic cells, which are able to further capitalize on the cost reduction from larger formats, can offer further reductions than those possible for cylindrical cells. However, none of these changes are sufficient to reach the DOE energy storage target of $125 kWh by 2020 , the study found.
