6 FAQs about [New Energy Battery Attenuation and Temperature]

Can a simple attenuation model capture the loss of battery capacity?

Ruan et al. proposed a simple attenuation model to capture the loss of battery capacity with DC discharge heating. The Pareto frontiers of heating time and capacity loss, two key but conflicting objectives, were obtained by using a multi-objective genetic algorithm.

How does electrolyte design affect battery discharge capacity?

The design and development of the electrolyte can reduce the freezing point of the solvent, improve the ionic conductivity, and then, increase the capacity of the battery at low temperatures, which result in a considerable improvement in the discharge capacity of the LIBs at low temperatures [14, 16].

What happens if a battery temperature distribution is uneven?

Uneven temperature distribution will result in uneven current and SOC distribution, which in turn leads to the fading of batteries electrochemical properties, furtherly the local accelerated aging. To this end, the design of heating strategy needs to consider the uniformity of battery temperature distribution.

What happens if a battery reaches a low temperature?

Under extremely low temperature conditions (below −20°C), due to the increase in the viscosity of the electrolyte, the diffusion rate of Li-ions in the electrolyte was severely reduced and the internal resistance of the battery increased sharply, which inevitably led to a substantial decrease in the power supply/absorption capacity .

How does temperature affect battery heat balance performance?

The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance. The temperature uniformity is poor due to the narrow space, and the temperature of the water heating the battery is also decreased with the increase of the distance the water flows through .
