6 FAQs about [The impact of low current charging on the battery]

What happens if a battery is charged at low temperatures?

Particularly, fast charging at low temperatures can cause lithium to deposit on the anode of the battery, intensifying heat production and even evolving into thermal runaway of the battery. Based on the simplified battery Alternating current (AC) impedance model, the optimal frequency of pulse current is analyzed.

How does current rate affect charging capacity?

The greatest variance is approximately 36% of the rated capacity, which shows that the current rate has a greater impact on the charging capacity. As the charging rate increases, the faster the active material reacts, the faster the battery voltage increases, and the energy loss generated increases.

How does temperature affect battery charging time?

When the temperature of battery reaches 0 °C from ambient temperature of −8.5 °C through heating of the pulse current, the total charging time is saved by 9% compared with the traditional constant current (1C) and constant voltage charging.

Why does pulse charging prolong battery performance?

This is due to the subsequent CC-CV charging stage after the battery temperature reaches 0 °C at the end of pulse charging. Therefore, the pulse charging method makes the electrolyte salt concentration distribution on the two electrodes more uniform, thereby prolonging the performance of battery.

How does particle size affect battery charging and discharging performance?

Generally speaking, the smaller the particles, the higher the charging and discharging efficiency of the lithium-ion battery. In addition, the diffusion coefficient in the lithium-ion battery has a significant impact on the charging and discharging performance.

What happens if a lithium battery is charged continuously?

At low temperature, lithium-ions diffuse more slowly in the electrode and electrolyte, and the intercalation dynamics are slow. In this case, the continuous charging of the battery will lead to a rapid decline in capacity, seriously limiting the application of LIBs .
