How to avoid explosions in 18650 batteries?

Nowadays, new energy supply methods can be used to address the issue of flammable electrolyte in lithium-ion battery brand packs, such as using human kinetic energy to supply energy to electronic devices. This method is still in the laboratory stage. Another very direct method is to add flame retardants to the existing electrolyte. However, in order to achieve flame retardancy, a lot of flame retardants need to be added to the electrolyte, which will correspondingly reduce the ion conductivity of the electrolyte, significantly affecting the electrochemical function and energy density of lithium-ion battery brand packs.

 
Recently, researchers from Stanford University in Guangdong province have developed a new type of intelligent electrospinning separator for 18650 lithium battery wholesale. It has a heat triggered mechanism and contains flame retardants inside, which can be used to prevent lithium-ion battery brands from burning.

In this structure, the flame retardant is packaged inside the polymer maintenance shell to prevent the flame retardant from directly dissolving into the electrolyte and causing negative effects on the battery function. When the heat inside the lithium-ion battery brand pack is too high, the battery maintenance case will dissolve due to high temperature, releasing flame retardants and effectively restraining the highly flammable electrolyte from burning.
 
1. Use original charger: Charging time is a high-risk period for lithium batteries brand pack explosion incidents. Original chargers can better ensure battery safety than compatible chargers.
 
2. Use reliable batteries: Try to purchase original batteries or well-known brands in the market, such as the lithium-ion battery brand of Youchuangweiye. Do not buy second-hand or parallel imported batteries to save money, as these batteries may not be as reliable as original batteries through repair.
 
3. Do not place the battery pack in extreme environments: high temperatures, bumps, etc. are important causes of lithium-ion battery brand pack explosions. Try to keep the battery in a stable environment and away from high temperature areas.

4. Do not modify: After modification, the battery may be in an environment that was not previously considered, adding safety hazards.
