Causes:
1. Thermal runaway: If the lithium battery overheats, it will burn, catch fire and explode;
2. Diaphragm Damage: There is a problem. Diaphragm inside the lithium battery. Yes, if the separator is damaged, the positive and negative electrodes will be in direct contact, causing the battery to short circuit and explode instantly.
Precautions for using lithium-ion batteries:
1. Do not bend or puncture the battery
2. When charging, do not overload the voltage; and the current should not exceed the specified values;
3. Use the original charger when charging.
Types of car batteries include nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, lithium-polymer batteries, and lead-acid batteries.
Use a clean eraser or other cleaning toolse cleaning to gently wipe the metal contacts of the lithium battery and the metal contacts of the mobile phone.
1. Use a clean eraser or other cleaning tools to gently wipe the metal contacts of the lithium battery and the metal contacts of the mobile phone, which will improve the charging status and power durability. .
2. Fully discharge the almost discarded lithium battery, then recharge it to activate the battery. The specific method is to deeply discharge the mobile phone, which is to achieve deeper charging by exhausting the internal energy.
Ternary lithium polymer battery refers to a lithium battery whose cathode material uses nickel cobalt lithium manganate ternary cathode material. It is a precursor product of a ternary composite cathode material, composed of nickel salt, nickel saltcobalt and manganese. salt. As raw materials, the proportion of nickel, cobalt and manganese can be adjusted according to actual needs.
