New energy lithium battery warehouse design

What are the solutions for lithium-ion battery full-line logistics?

The solutions for Lithium-ion battery full-line logistics include logistics of upstream raw material warehouses, workshop electrode warehouses, battery cell segments, latter stage of formation and capacity grading, as well as logistics of finished product warehouses and modules and packs. equipment.

Does lithium-ion battery warehouse have a fire propagation behavior?

The fire propagation behavior of lithium-ion battery warehouse was studied. The SOC value of stored lithium-ion batteries should be as small as possible. When storing 70%–100% SOC batteries, a quick-response sprinkler shall be set. To prevent the spread of fire, a critical value of shelf spacing is defined.

Are lithium-ion battery warehouses prone to fire accidents?

With the rapid development of LIBs, reports on accidents in the production, storage, and transportation of LIBs have continued to emerge in recent years; specifically, there has been a frequent occurrence of fire accidents in the lithium-ion battery (LIB) warehouses.

What if a Lib warehouse stores batteries with a high SoC value?

Therefore, when a LIB warehouse stores batteries with a high SOC value, active ventilation facilities such as mechanical ventilation should be set in the warehouse to prevent personnel from being affected by smoke during an emergency evacuation after a fire occurs. Fig. 10. Smoke layer height at point An under different battery SOC values. 4.2.

Should lithium ion batteries be stored at a low SOC level?

This is in line with the standard of “Safety Production Code for Lithium-ion Battery Enterprises (T/CIAPS0002-2017)" in which it is recommended that LIBs be stored with SOC reduced to below 70% after leaving the factory, but here the standard is only recommended and not mandatory.

Are lithium-ion batteries at risk of thermal runaway?

Due to its instability and thermal runaway, a lithium-ion battery (LIB) has always been at severe risk in the process of transportation and storage. Recently, numerous studies have been conducted on the risk of thermal runaway in LIB storage, but most of them have focused on small-scale micro mechanisms.
