6 FAQs about [How to control voltage reduction in battery production]

Does micro-level manufacturing affect the energy density of EV batteries?

Besides the cell manufacturing, “macro”-level manufacturing from cell to battery system could affect the final energy density and the total cost, especially for the EV battery system. The energy density of the EV battery system increased from less than 100 to ∼200 Wh/kg during the past decade (Löbberding et al., 2020).

How can battery manufacturing improve energy density?

The new manufacturing technologies such as high-efficiency mixing, solvent-free deposition, and fast formation could be the key to achieve this target. Besides the upgrading of battery materials, the potential of increasing the energy density from the manufacturing end starts to make an impact.

Can new battery materials reduce the cost of a battery?

Although the invention of new battery materials leads to a significant decrease in the battery cost, the US DOE ultimate target of $80/kWh is still a challenge (U.S. Department Of Energy, 2020). The new manufacturing technologies such as high-efficiency mixing, solvent-free deposition, and fast formation could be the key to achieve this target.

How a new material design can improve battery manufacturing?

In this regard, novel material design, together with next-generation manufacturing technologies, including solvent-free manufacturing, will help in making the process cost-effective and environmentally friendly. Technology is evolving towards Industry 4.0; therefore, it is inevitable for battery manufacturers to get their share.

Why is battery production a cost-intensive process?

Since battery production is a cost-intensive (material and energy costs) process, these standards will help to save time and money. Battery manufacturing consists of many process steps and the development takes several years, beginning with the concept phase and the technical feasibility, through the sampling phases until SOP.

How can a laboratory help the development of a battery system?

The limited resources and space in the laboratory restrict the research activity on the battery system. Therefore, more collaboration between academic researchers and battery manufacturers could help the development of battery systems. Recycling becomes an inevitable topic with the surging of LIB manufacturing capacity.
