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: 1. Allowed portable lithium battery: It can be used as hand luggage to carry personal portable electronic equipment such as notebook computers, mobile phones, cameras and other spare batteries containing no more than 100Wh lithium batteries and spare batteries to board passenger aircraft. 2. Restricted lithium batteries: With the approval of airlines, electronic equipment that can carry more than (including) 100Wh but not more than 160Wh lithium batteries can be boarded. Each passenger cannot carry more than two such spare lithium batteries and cannot consignment. 3. Prohibited lithium batteries It is forbidden to carry or consigne large lithium batteries or electronic equipment over 160Wh (except wheelchairs with lithium ion batteries). 4. P...

Lithium-ion batteries will face the risk of excessive self-discharge during long-term storage, especially at lower open-circuit voltages. Due to excessive self-discharge, the voltage of the lithium-ion battery may be too low, causing negative and negative copper foils dissolution and other risks, because the dissolved copper element will be precipitated on the surface of the negative electrode again during the charging process, the generated metal copper dendrites may pierce the separator, causing a short circuit between the positive and negative electrodes, so excessive discharge or low voltage will cause the lithium ion battery completely failed. At present, we are not particularly clear about the reaction occurring inside the lithium-ion battery during the overdischarge process. In order to understand this reaction process, Johannes Kasnatscheew et al. Of the University of Münster in Germany used a three-electrode system to positive and negative lithium ion batter...

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: The main production steps of lithium battery cells Pulping A special solvent and binder for pulping are mixed with the powdery positive and negative electrode active materials, and evenly mixed at a high speed to make a slurry-like positive and negative electrode materials. Coating The coating film uniformly coats the prepared slurry on the surface of the metal foil and dries to form positive and negative pole pieces. Assembly The assembly is placed in the order of the positive electrode sheet-separator-negative electrode sheet-separator from top to bottom, wound to make the battery core, and then inj...

The best 18650 lithium-ion battery pack The 18650 lithium-ion battery pack is a finished lithium-ion battery assembled by different numbers of 18650 li-ion batteries through a protective circuit board. The most important part of the 18650 lithium battery is: 18650 cells, protection circuit board (commonly called PCM board) and battery assembly process production line. 1). 18650 cells The 18650 cell refers to a cylindrical cell with a diameter of 18 mm and a length of 65 mm. 2). Protection circuit board Composition: IC: Control MOS: switch NTC: negative temperature coefficient resistance ID: Recognizable resistance Fuse / Ptc: blow the fuse for protection 3). Battery assembly process production line With the continuous development of the PACk process and the continuous improvement of the connection method, from the original wire soldering process to the nickel sheet soldering process, to the nickel sheet spot welding process, to the current laser spot ...

It has been half a century since the first commercial lithium battery was released by Sony in 1991. Lithium batteries are closely related to our daily life and are inseparable. They are widely used in various electronic products. In order to protect the rights and interests of consumers, the safety of products More and more attention is being paid to it; the safety of the battery bears the brunt. At present, the safety certification of lithium batteries in all countries is quite strict, and many countries are mandatory certification tests. Lithium battery testing is generally done by looking for a qualified third-party testing agency to test the safety performance of the battery by sending samples, and can issue corresponding test reports and certificates. At present, our company has its own laboratory. The laboratory has a full set of safety testing equipment, which can independently detect the safety performance of the battery, which provides a strong guarantee f...

Lithium-ion batteries have been commercialized since the 1990s. Nowadays, they have entered the daily life of ordinary people. We use mobile phones, tablets, smart watches, VR glasses, digital cameras and other portable electronic products, almost all use lithium-ion batteries. The lithium-ion battery itself also developed from the early aluminum and steel cases to flexible packaging. Due to the flexible packaging of lithium-ion batteries , the shape and size of the lithium-ion batteries are more flexible, and the safety performance is superior. Become as the favorite application battery. However, it is an indisputable fact that lithium-ion batteries in flexible packaging are more likely to swell than aluminum or steel batteries. The main reasons for the inflation of soft-pack lithium-ion batteries are: 1. Over-charge. In the over-charged state of lithium-ion batteries, the positive electrode (anode) material will release too many lithium ions, which causes i...
