The development of automobiles to electrification and intelligence is becoming a trend, which brings about the rapid development of the lithium-ion power battery industry. In particular, ternary lithium batteries, with their high energy density, have become the first choice for passenger car power batteries. The technical core of the ternary lithium battery lies in its cathode material, and the performance of the cathode material depends on its raw material processing technology, that is, the quality of the ternary precursor. Therefore, the production process of the ternary precursor and its quality assurance are very important to downstream customers.
ternary precursor is mainly nickel-cobalt-manganese or nickel-cobalt-aluminum hydroxide. The preparation of the precursor uses nickel salt, cobalt salt, manganese salt (or aluminum hydroxide) as raw materials, and salt-alkali neutralization reaction occurs in ammonia water and alkali solution to produce nickel-cobalt-manganese (aluminum) hydroxide precipitation. The ternary material precursor is then obtained by washing with deionized water until no sulfate remains, and then drying the precipitate.
Promin can provide products:
, customized into prying dosing system (including metering pump gamma/ X or Sigma)
2, measurement and control system
during the preparation process, the concentration of salt and alkali, the concentration of ammonia water, the rate at which the salt-alkali solution is added to the reactor, etc. will all affect the quality of the final precursor. To ensure the stable production of precursor quality, the precise dosing of salt-alkali solution is very important. Using the smart metering pump of Promin can solve this problem perfectly. For example, the simultaneous measurement of various metal salt solutions at a rate of 5 to 20 liters/minute, and the measurement of complexing agents at a rate of 10 to 40 liters/minute are also required to ensure that the pH value in the reactor is constant by controlling the dosage of various solutions.
Promin's fully intelligent adjustable electromagnetic linear drive metering pump gamma/ X can be applied to the above conditions. It can achieve precise metering of liquids from 2.3 to 80 l / h at a back pressure of 25 - 2 bar. The pump head integrates pressure measurement and display, without additional sensors, and displays pressure data in real time through the screen. Its linear electromagnetic control technology ensures that hydraulic faults are detected quickly and corrected immediately, even with minimal deviations.
When the reactor is of large capacity and the required dosing solution exceeds the flow range of gamma/ X, our fully intelligent vector control motor can be used to drive the metering pump Sigma X , which can realize precise metering of liquid from 21 to 1040 l / h under a back pressure of 16 - 4 bar. Like gamma/ X, it has the characteristics of automatic hardware identification, simple operation interface, microprocessor controller and intelligent vector control frequency converter.

Which brand of Japanese Ni-MH battery is more stable and durable?
Under normal use of nickel-metal hydride batteries, generally speaking, the discharge time of power batteries with high capacity is long, and the discharge time of small capacity is short. However, there are two kinds of performance: stability and durability in the use effect. They become an important reference factor for positioning Ni-MH batteries, because if the stability and durability are insufficient, after encountering some abnormal use, Ni-MH batteries that show the battery life according to their capacity may have some variables, and even the high capacity is not durable due to insufficient stability. After testing five mainstream Japanese nickel-metal hydride battery brands, a Japanese media believes that Sanyo products are the most stable and durable.
Summary of Lithium-ion Battery Safety Test Items and Methods
Lithium-ion batteries and monolithic samples consisting of non-user replaceable batteries/lithium-ion batteries and their electronics. For non-user replaceable batteries, they should be installed in electronic products as a whole sample for the environmental safety test of lithium ion batteries in the standard. For non-user replaceable lithium ion batteries, they can be placed in electronic products as a whole sample, or the lithium ion battery can be taken out separately for the environmental safety test of lithium ion batteries in the standard. It is recommended to test as a whole sample first. As the test process may be deflated, smoke, fire or even explosion, it is necessary to take the necessary protective measures
Main battery type recycling methods and their recycling purposes
Different types of lithium batteries are widely used in different occasions, more scientific and economical recycling of waste batteries for reuse is a cause conducive to nature and human health. After hundreds of years of development, the basic recycling methods for major battery brands are the same in countries around the world. 1. dry batteries: alkaline manganese dry batteries and zinc manganese dry batteries, that is, generally referred to as carbon batteries and alkaline batteries. This type of battery is currently required to ban the use of mercury, so it is safe in life. For this reason, there is no requirement to recycle such batteries. Of course, those who are willing to recycle can engage in this aspect of business, and users do not have any in the garbage can.
Explosion-proof measures for battery and lithium battery
The safety of lithium-ion batteries has always been an important issue that plagues the industrialization of lithium batteries. The battery explosion accidents exposed in recent years are all caused by the use of lithium batteries. Compared with other types of batteries, this is determined by the special nature of lithium battery materials and processes. To this end, we should understand the knowledge of lithium battery explosion, we try to explain from the following three aspects. 1., the national standard stipulates that any part of the solid material within the battery is instantly discharged, and the distance that is pushed to the lithium battery above 25cm is called an explosion. The identification method in the experiment is: cover the experimental battery with a circular mesh so that the battery is located at the center of the circle, I .e. 25cm from any side of the mesh cover. If no solid part of the experiment passes through the mesh cover, it is proved that the battery has not exploded. Here, the "net" has a specific to show: the net wire adopts a soft aluminum wire with a diameter of 0.25mm, and the density of the net is 6~7/cm. 2. how to prevent lithium battery explosion All lithium battery explosions are caused by short circuit caused by battery heating, and the cause of short circuit and over charge, over discharge, positive and negative direct docking, electrolyte leakage and so on. Therefore, in the design of lithium batteries, the following points can be started: 1. It is forbidden to overcharge the battery to more than 4.2V; 2. It is forbidden to overcharge the battery to less than 2.75V; 3. An explosion-proof valve is installed on the metal shell; 4. Prevent short circuit in the process. The best way, of course, is to have a battery protection circuit board design. Although this will increase the manufacturing cost of lithium batteries, it is necessary for the safe use of lithium batteries. All regular lithium battery manufacturers can not avoid this design. 3. polymer lithium battery is the use of flexible packaging and polymer electrolyte made of a lithium battery products, under normal circumstances, the use of storage will not explode, unless man-made strong damage caused by its short circuit. In order to reduce the occurrence of explosion accidents, polymer lithium batteries are being used in more and more occasions. Although lithium batteries are still in the process of replacing other types of batteries, polymer lithium batteries have begun to replace ordinary lithium batteries in some areas.
