Lithium Battery Knowledge
Lithium battery electrolyte is the carrier of ion transmission in the battery. Generally composed of lithium salt and organic solvent. The electrolyte plays a role in conducting ions between the positive and negative electrodes of the lithium battery, ensuring that the lithium ion battery has the advantages of high voltage and high specific energy. Electrolyte is generally prepared from raw materials such as high-purity organic solvents, electrolyte lithium salt and necessary additives in a certain proportion under certain conditions.
1. Lithium-ion battery type and capacity selection
2. Screening and assembly of batteries
Many times, when people go out, they will encounter the situation that the mobile phone is out of power and forget to bring the power bank and charger, which brings certain inconvenience to life. If there is such a piece of clothing, it looks no different from ordinary clothes, but it can wirelessly charge mobile phones and other electronic devices. Isn’t it exciting?
Polymer lithium ion batteries can be divided into three categories:
1. Solid polymer electrolyte lithium ion battery.
2. Gel polymer electrolyte lithium ion battery.
3. Lithium-ion battery with polymer cathode material.
Advantages of lithium polymer battery:
1. Good safety performance
2. The thickness is small and can be made thinner
4. Large capacity
5. Small internal resistance
6. The shape can be customized
7. Good discharge characteristics
8. Simple protection board design

There are many reasons for the explosion of 18650 lithium-ion batteries, mainly three.
2. Short circuit
3. High temperature
Earlier power banks gave most users a big and heavy impression, but today's power banks are small, especially shared ones. Friends who have used it will feel very light. This is the credit of the polymer lithium-ion battery. In fact, due to the emergence of polymer lithium-ion batteries, many electronic products can perform better, such as TWS Bluetooth headsets and special small electronic devices. Unlike a few years ago, there are fewer and fewer 18650 lithium-ion batteries used in mobile power sources. Is it really eliminated? In addition to volume and weight, what is the difference between polymer lithium ion battery and 18650? This is what we are going to talk about today.
1. Charge in time every day
2. Don't change the charger casually
3. Protect the charger
4. Pay attention to the charging environment
5. Develop some good habits to save electricity
6. Make full use of maintenance conditions
Lithium iron phosphate batteries are used to make lithium-ion secondary batteries. Nowadays, the primary direction is power lithium-ion batteries, which have great advantages compared to NI-H and Ni-Cd batteries.
The general lithium-ion battery is commonly known as "lithium battery", which is currently a battery system with relatively good overall performance. The negative electrode of a lithium-ion battery is a carbon material, such as graphite. The positive electrode is a transition metal oxide containing lithium, such as LiMn2O4.
