\r\nEffect of Temperature on Lithium-ion Batteries<\/h2>\r\nAll batteries experience a loss in performance at low temperatures. The ideal storage temperature for most batteries, including lithium-ion, is 59\u00b0F (15\u00b0C).\r\n\r\nTemperatures dipping down at or close to 32\u00b0F (0\u00b0C) cause a slow-down in the chemical reactions inside of the cell\u2014resulting in a loss in capacity of the battery.\r\n\r\nWhen users put a battery under heavy load at cold temperatures it can cause a phenomenon known as cell reversal. This is a common cause of failure in cordless power tools. Users who need their lithium ion batteries to function in cold climates should be aware of these temperature effects on batteries. Store them in a safe, temperature-controlled space during the winter months.\r\nInternal Safety Mechanisms for Lithium-ion Battery Packs<\/h2>\r\nBecause several applications use battery packs, which are a combination of individual cells, manufacturers have built the following safety measures into the packs to minimize safety incidents:\r\n\r\n \t- Temperature sensors monitor the temperature of the cell<\/li>\r\n \t
- Voltage regulators monitor and control the output of each cell<\/li>\r\n \t
- Sensors measure and report the actual battery charge percentage<\/li>\r\n \t
- Separators prevent a runaway temperature moving from one cell to the next<\/li>\r\n<\/ul>\r\n

Failing to adhere to the recommended storage temperature can permanently damage the capacity of lithium ion batteries.\r\n\r\n![\"\"](\"https:\/\/uschemicalstorage.com\/staging\/wp-content\/uploads\/2020\/02\/Lithium-Storage-Building-Shelves-300x199.png\")
\r\n\r\nFor example, a battery stored at 104\u00b0F (40\u00b0C) for 1-year will only retain 85% of its original capacity, while a battery stored at 77\u00b0F (25\u00b0C) will retain 96% of its capacity. It is also important to store batteries at the optimum charge level of 40%. Storing lithium ion batteries fully charged accelerates the loss of capacity. A fully charged battery stored at 104\u00b0F (40\u00b0C) will lose 35% of its capacity in only 3 months.\r\n\r\nOne of the greatest risks for lithium-ion batteries is physical damage to the battery itself. Damage can cause a short between the anode and cathode, leading to a spike in current at that point in the cell. As a result, the battery\u2019s temperature increases, which can lead to a thermal runaway \u2013 also known as a fire.\r\n\r\nIf a lithium battery pack does catch fire, it can be extinguished with foam, CO2, or dry chemical fire extinguishers; water may cause further damage.\r\n\r\nBecause fires can spread from one cell to the next in a lithium ion battery and this transfer may take some time to manifest, it is vital that the burnt battery be isolated for some time to alleviate further fire risk.\r\n

ATC focuses on remanufacturing, repair, and refurbishment of NiMh and Lithium Ion batteries and components.\r\nATC NT’s Needs<\/h3>\r\nATC NT required an industrial chemical storage building in which their team could safely rebuild, and repair used batteries.

For maximum safety, a clean agent FM 200 fire suppression device<\/a> was installed in case a fire hazard occurred inside the building.\r\n\r\nIn addition to safety and temperature stabilization precautions, worktables were installed inside the DrumLoc building. The stable tables make a convenient workspace when rebuilding and repairing batteries on-site.\r\n\r\nIn conclusion, our team at U.S. Chemical Storage was able to design a state-of-the-art lithium battery storage facility, while incorporating the strongest and most reliable lab equipment and accessories custom-built for ATC NT\u2019s operations.\r\n
