How much does a battery cost?

The paper gives a detailed overview of the cost types in both batteries in a cost breakdown. Their methodology includes learning curves. These learning curves are abstracted from current and estimated future global electric car numbers. For the year 2020, the publication assumes a battery sales price of between 130 and 200 USD per kWh .

How does the review contribute to the field of battery cost modeling?

The review contributes to the field of battery cost modeling in different ways. First, the review provides a detailed overview of the most relevant studies published in the field of battery cost modeling in the recent years. Second, we introduce a framework for the evaluation of future cost models.

How are the costs of a complete battery system calculated?

The costs of a complete battery system, based on cathode active material price scenarios calculated in the work, are represented by a linear regression that accounts for economies of scale. The costs for the battery system were differentiated into cost types, but not into process steps .

What are the main cost types for battery production?

The article identifies main cost types for battery production as land acquisition, construction, equipment, liability, material, utilities, logistics, and labor. The comparison is based on 18650-cells with a NMC cathode chemistry. The work identifies a gap inside the labor costs between the two countries.

Can battery costs be forecasted?

Within this transformation, battery costs are considered a main hurdle for the market-breakthrough of battery-powered products. Encouraged by this, various studies have been published attempting to predict these, providing the reader with a large variance of forecasted cost that results from differences in methods and assumptions.

How many studies are based on battery costs?

So far, there is no review available which systematically evaluates these publications and their underlying parameters. To close this gap, we initially identified 633 studies which are related to the topic of battery costs. Subsequently, we developed a framework to identify the most important contributions.
