3. Graphene Since winning the Nobel Prize in 2010, graphene has received widespread global attention, especially in China. There has been a wave of research and development in China for graphene, which has many excellent properties, such as good transparency, excellent condu...

During the charging and discharging process, the volume expansion can reach 300%, which can lead to the pulverization of silicon material particles and cause material capacity loss. Poor suction ability at the same time. Poor cycle life. At present, the above problems are be...

1. Silicon carbon composite negative electrode material After the large screen and diversified functions of digital terminal products, new requirements have been put forward for battery life. The current low capacity of lithium battery materials cannot meet the increasing de...

18650 battery cannot be charged into electrolysis solution: 1. The charger interface is aging or the charger itself is damaged. Replace with a new charger for testing. 2. There is an issue with the quality of the charging circuit. Replace with a new pipeli...

Reasons for the inability to charge 18650 lithium-ion batteries 1. Internal charging circuit malfunction, unable to charge normally. 2. There is an internal malfunction in the 18650 lithium-ion battery. 3. The contact between the battery...

Explosion type analysis The types of battery cell explosions can be summarized as external short circuits, internal short circuits, and overcharging. The exterior here refers to the exterior of the battery cell, including short circuits caused by poor insu...

Reason for lithium battery explosion: 1. Large internal polarization; 2. The electrode absorbs water and reacts with the electrolyte, causing a gas bubble; 3. Quality and performance issues of the electrolyte itself; 4. The am...

Protection measures: After overcharging the lithium-ion battery cell to a voltage higher than 4.2V, it will begin to have side effects. The higher the overcharging voltage, the higher the danger. After the voltage of a lithium battery cell exceeds 4.2V, less than half of the lithium atoms remain in...

Lithium is the smallest and most active metal on the chemical periodic table. Due to its small size and high capacity density, it is widely welcomed by consumers and engineers. However, if the chemical properties are too active, it brings extremely high danger. When lithium metal is exposed to...

If there is an inconsistency in the charging capacity of the battery pack, the solution is as follows: A. Use a management system with balancing function and excellent balancing effect, preferably one with balancing charging function. B. Charge all individ...
