Lithium ion battery usage requirements

source:Industry News release time:2024-04-07 Hits:     Popular:AG11 battery

  

  Although lithium-ion batteries have become popular, there are not a few battery explosions every year, so the use of lithium-ion batteries is particularly important. Polymer lithium-ion batteries are much safer than liquid lithium-ion batteries. When the liquid lithium-ion battery is overcharged, the positive residue continues to transfer to the negative electrode, but the negative electrode cannot be embedded more, resulting in metal Li precipitation from the negative electrode, damage to the isolation film, battery short circuit, battery temperature rise, active Li metal and its compounds inside the battery are easy to produce leakage, explosion, etc. Overdischarge of the battery, because the negative electrode needs to maintain a certain amount in order to maintain a stable structure, overdischarge makes more move out, resulting in irreversible damage to the negative electrode.

  Lithium-ion battery memory effect is ignored, the battery overcharge and overdischarge will damage the internal compound lattice, resulting in reduced capacity and shortened battery life. Therefore, the battery protection board must be used, but the protection board is not absolutely able to protect the battery. In practice, with smart charger charging, and strict use specifications.
