What are the hidden dangers of using lithium batteries?

Lithium batteries are the most common power source for smartphones and tablets. However, there have been several explosions of mobile phone lithium batteries. Fire department experiments have shown that once lithium batteries are physically damaged, they will swell and smoke, especially when they are immersed in water. It is known that the chemical properties of metal lithium are very active and belong to wet dangerous goods. It will release flammable gas when exposed to water or humid air. In fact, the heating or burning of lithium batteries is mainly caused by short circuits and excessive current, but for mobile phones, excessive charging and discharging currents will not occur. Therefore, there are many factors that cause the short circuit of the lithium battery, including the physical damage of the battery, the temperature of the working environment, and the short circuit of the positive and negative electrodes. If the outer shell of the lithium battery is damaged, it will cause a short circuit inside the battery, leading to heat generation and burning. Therefore, when carrying electronic devices containing lithium batteries, it is best to package them separately and insulate them. Must pay attention to prevent exposure to the sun, but also to prevent violent bumps. There is a problem with the battery effect M. His uncle was appointed as the marketing manager of M company because of his extensive experience in marketing. Another promising young man Z was appointed as the deputy manager of this department. Old people and young people should work together and complement each other, so they should be more efficient. However, the contradiction between the old and young employees made the marketing department unable to carry out the work and affected the development of the entire company. I want to move them away, but he can't make up his mind. One day, due to night patrols, I bought two flashlights with new batteries. In order to save money, he was unwilling to throw away old batteries with a certain amount of power, so he used new and old batteries together, but the brightness did not increase, but weaker. His son, who is now in high school, told him that it was because the old battery became a battery, wasting the energy of the new battery. Such a simple truth suddenly reminded M of the company's marketing department. The manager's uncle is conservative in his thinking, often based on the old relevant experience, and it is difficult to accept new things, in the contradictions and bold thinking, dare to do, weird tricks ZZ some active and effective marketing strategies can not be realized, hindering the new market development of. Inspired by the battery effect, M made a decisive personnel adjustment: Z was promoted to marketing manager. In addition, a young assistant has similar interests to him and chose for him during his golden age. My uncle was transferred to the company's stock manager and worked with a steady and kind old man. As a result, the market sector is booming and the material warehouse is well managed. Expert comment: The allocation of talents must be reasonable in order to maximize the use.
