The working principle of the vacuum cleaner is to use a motor to drive the blades to rotate at a high speed, and negative air pressure appears in the sealed casing to absorb dust. The cordless vacuum cleaner can complete the vacuuming work without a power cord. Just like a mobile phone, it uses the built-in battery to keep the machine running. There is no need to look for power everywhere, let alone worry about the baby at home being tripped by the wire. Cordless vacuum cleaners generally use power lithium-ion batteries, which are composed of several 18650 lithium-ion batteries in series and parallel to form a lithium-ion battery pack. The lithium-ion battery protection board has protection functions such as over-charge, over-discharge, over-current, and short circuit. Give full play to the safety and stability of the power lithium-ion battery pack. It can work continuously for up to 2040 minutes on a single charge. The advantages of power lithium-ion batteries are lar

Lithium batteries are widely used in electric tools, lighting, wind energy storage, electric cars, toys, instrumentation, UPS backup power, communication equipment, medical equipment and special lamps. So what is the price of lithium batteries? How do lithium battery manufacturers in the market price lithium batteries? What is the price of lithium batteries? How do lithium battery manufacturers price lithium batteries? The pricing of lithium batteries is based on capacity, which is calculated per 1000mAh (1Ah). According to current standards, the average price of lithium batteries on the market ranges from US$0.9-1.5 per 1000mAh when they leave the factory, and the average price is around US$1.3. Moreover, the production difficulty and price of different materials of lithium batteries are different. Including lithium cobaltate, lithium manganate, lithium nickelate, lithium iron phosphate, ternary and other materials. For example: Lithium cobalt oxide usually costs 1.3 U

KC certification is a national unified certification mark implemented by the Korean National Standards Committee. Lithium batteries are included in the KC certification catalog as a compulsory certification product. At present, the testing of portable secondary lithium battery packs and lithium batteries must be performed by authorized laboratories in South Korea, and cannot be transferred with the CB report of IEC 62133. After the product has passed the evaluation, it will be issued a Confirmation Letter of Declaration valid for 5 years, during which no factory inspection is required. Lithium battery KC certification model, KC certification is divided into the following two models: Mandatory safety certification (factory audit required) Self-discipline safety certification (no factory audit required) Note: Compulsory certification is valid forever, and the self-discipline certification is valid for five years. Lithium batteries are self-disciplined. Lithium battery KC cer

  What are the models and specifications of lithium-ion battery cells? How many types of Lithium batteries are there? In fact, there are many types, because each battery manufacturer has its own type and specifications, and there are some customized battery specifications. The following introduces the naming of lithium battery model specifications and the meaning of the letters and numbers on the battery, so that everyone has a better understanding of the battery model specifications. Cylindrical lithium battery model specifications The model name of cylindrical lithium battery consists of three letters and five digits. IEC61960 stipulates the rules for cylindrical and square batteries as follows: Cylindrical lithium battery, 3 letters followed by 5 numbers. 3 letters, I means there is built-in lithium ion, L means lithium metal or lithium alloy electrode. The second letter represents the cathode material, C represents cobalt, N represents nickel, M represents manganes

1. Lithium Cell produce process part (1) There is too little conductive agent in the positive electrode ingredients (the conductivity between materials is not good, because the conductivity of lithium cobalt itself is very poor) (2) There are too many binders in the positive electrode ingredients (binders are generally polymer materials with strong insulating properties) (3) There are too many binders in the negative electrode ingredients (the binders are generally polymer materials with strong insulating properties) (4) Uneven distribution of ingredients (5) The binder solvent is incomplete when compounding (not completely soluble in NMP, water) (6) The surface density of coating and drawing is too large (large ion migration distance) (7) The compaction density of the lithium ion battery is too large, and the roller is too compact. (Rolling is too dead, and some of the active material structure is destroyed) (8) The positive lug is not welded firmly, and there is a virtual we
