Benzo Battery News
After years of development, the lithium battery industry has formed a complete industrial chain with a high degree of specialization. Do you know how the lithium battery is made?
BYD: The blade battery can still discharge 90% at minus 10°C, with a mileage of 1.2 million kilometers
The battey as one of the most important parts of electric vehicles, batteries are also valued by major car companies. At present, there are mainly two types of batteries used by car companies to install vehicles: ternary lithium batteries and lithium iron phosphate batteries. However, BYD's blade battery (a new generation of lithium iron phosphate battery) was born, and car companies also have a more competitive battery option.
Both the camera drone battery and the mobile phone battery are lithium-ion batteries. The drone battery is the source of power for the device and has higher requirements for its safety performance. However, there is a difference between the two. The drone battery has a significant feature compared to the mobile phone battery --- high rate discharge. The drone battery needs a large current to discharge to meet the requirements of the drone in different environments. For example, in aerial photography, if a strong wind is encountered, the battery must be discharged with a large current to ensure the stability of the drone's position. Because of different requirements, the life of the camera drone battery is relatively short.
Polymer lithium ion battery is a kind of lithium ion battery, but compared with liquid lithium ion battery (Li-ion), it has high energy density, more compact, ultra-thin, light weight, high safety and low cost Many obvious advantages are a new type of battery. Below we detail the advantages and disadvantages of polymer lithium-ion batteries:
Generally speaking, the most common power batteries are lithium iron phosphate batteries, lithium manganate batteries, lithium cobalt oxide batteries, and ternary lithium batteries.
Why does the lithium ion battery capacity loss? Can the power loss of the lithium ion battery be repaired?
Lithium-ion batteries are the driving force of electronic products. If the battery consumption of electronic products is too large, the battery life of electronic products will be greatly reduced. Many users complain that the battery life of their electronic products is too short. If they are used for a long time, the battery life of the lithium-ion batteries of electronic products will be relatively weakened. The common problem of lithium-ion batteries in daily use is power loss. The more exhausted, the greater the battery loss.
The impact of high temperature on lithium-ion batteries, is high temperature the cause of bulging lithium-ion batteries?
Among all environmental factors, temperature has the greatest influence on the battery's charge and discharge performance. The electrochemical reaction at the electrode / electrolyte interface is related to the ambient temperature. The temperature rise means that the output power of the lithium ion battery will rise. The temperature also affects the transfer speed of the electrolyte. The temperature rises faster, the transfer temperature decreases, and the transfer slows down. The battery charge and discharge performance will also be affected. However, if the temperature is too high above 45 ° C, the chemical balance in the battery will be destroyed, causing side reactions.
The following uses a lithium ion battery with a standard voltage of 4.2V as an example
If the voltage is 4.2V after full charge, it is ok. If the battery time is more than 0.7 times of the new battery, it means the battery is not bad. If the volume voltage is higher than 4.2V after full charge, it means that the charger has problems. (Note The voltmeter must be accurate). Please see the introduction below.
Lithium batteries are widely used in people's lives, such as digital products such as cameras and notebook computers, as well as some other electrical appliances.
Tips for safe transportation of lithium batteries:
If you want to guarantee the product quality of lithium battery cells, you must ensure that the production equipment for producing lithium battery cells runs well.
There are many steps in the production of lithium battery cells, and there are many production-related equipment. Here we will introduce the main steps and equipment of the cell production process:
