How to optimize battery cell design parameters?

The optimization of design parameters by modeling, simulation, and experimental validation is shown in Fig. 21. Numerical modeling has been useful to reduce the tiresome jobs of the trial-and-error process of determining battery cell parameters and operating conditions.

What is the recycling efficiency of NIB batteries?

The whole solid-component recycling efficiency of our proposed NIB cell is ca. 98.1%, which is close to that of lead-acid batteries with heavily regulated disposal 4. The only losses are the metallic Na, conductive additive, and polymer binder (Supplementary Fig. 11). More importantly, this design can also be extended to other battery systems.

What is the energy density of a Li-air battery?

The Li-air battery can deliver the highest theoretical specific energy of 3500 Whkg −1 but the energy density can be limited to 400–450 Whkg −1 in reality due to certain limitations and the necessity of auxiliary units.

What is a mathematical model in battery design?

Mathematical models have a long history in the case of battery design. The distribution of current and potential in porous electrodes was first introduced in the late 1950s using a macro-level mathematical model.
