UN3480 must comply with the packaging instructions for PI965, and UN3481 must comply with the packaging instructions for PI966 (packaged with the device) or PI967 (lithium battery installed in the device) .
Lithium metal batteries (including lithium alloy batteries): Lithium batteries with lithium metal or lithium alloy as an anode, usually non-rechargeable disposable batteries. Lithium metal batteries are often used in electronic watches, calculators, cameras, etc., such as button batteries.
Lithium batteries are generally divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation product of rechargeable batteries, lithium metal batteries, was born in 1996. Its safety, specific capacity, self-discharge rate and rperformance-price ratio are better than those of lithium-ion batteries.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It was invented by Edison. The reaction equation used by the battery is: Li+MnO2=LiMnO2. This reaction is an oxidation-reduction and discharge reaction. In the past, because the chemical properties of lithium metal are very active and the environmental requirements for processing, storage and use are very high, lithium batteries have not been used for a long time. With the development of modern science, lithium batteries have now become common. On February 22, 2016, ICAO announced a ban on checked baggage containing lithium batteries.
How to distinguish lithium batteries from batteries lithium polymer
The main lithium batteries used in vehicle batteries in China's electric vehicle industry are three types of iron-lithium and manganese lithium, three yuan.
1 Lithium Manganese
Advantages: cheap price; good low temperature performance, discharge efficiency over 90% at minus 20 degrees;
Disadvantages: poor performance at high temperatures; low lifespan (generally normal lifespan is about 300-400 times the low specific capacity in grams (112); starts quickly), has a great impact on this type of battery)
2 Ternary
Advantages: The price is the most expensive of the three high-capacity materials (150. can save; volume); good service life (600-700 times); good discharge rate.
Disadvantages: Safety performance is the worst of the three (especially those with steel hulls); at present, the industryThe Chinese battery industry is not yet mature enough to master this material and does not use it much. ?
3 Lithium iron?
Advantages: average price; medium capacity (130); high lifespan (about 1500 times); good high temperature performance
;Disadvantages: Price is not cheap; low temperature performance is not good; its superior performance can only be fully reflected in electric vehicles (can be fully charged in 6 minutes and discharged 20 times)
Detailed information:
Identification method:
1 Compare the battery capacity. The general nickel-cadmium battery is 500 mAh or 600 mAh, and the nickel-hydrogen battery is only 800-900 mAh; and the capacity of lithium-ion cell phone batteries is generally between 1300 and 1400 mAh, so that the lithium battery can last longer after being used. fully charged is about 1.5 times that of nickel-hydrogen battery, or about 3.0 times that of nickel-cadmium batteries.
If you find that the operating time of the lithium-ion cell phone battery you purchased is not as long as advertised or specified in the manual, it may be counterfeit.
2 Look at the plastic surface and the plastic material. The original battery has a uniform wear-resistant surface and is made of PC material, which is not fragile. Counterfeit batteries do not have a wear-resistant surface or are too rough and are made from recycled materials that are prone to brittleness.
3 Measure the battery pack charging voltage. If a nickel-cadmium or nickel-hydrogen battery pack is used to simulate a tee battery packlithium-ion cell phone, it must be made up of 5 individual cells. The charging voltage of a single battery generally does not exceed 1.55V and total. The battery pack voltage does not exceed 7.75 V. When the battery pack is when the total charge voltage is less than 8.0 V, it may be a nickel-cadmium or nickel-hydrogen battery .
4 For original batteries, the color and texture of the battery surface should be clear, uniform, clean, without obvious scratches or damage; the battery brand should be printed with the model, type, rated capacity of the battery. standard voltage, positive and negative Extreme Logo, manufacturer name.
It must be smooth and unobstructed, have a suitable seal, fit the hand well and have reliable locking; the material must not have obvious scratches or black or green spots. If the battery of the cell phone we purchasedns does not conform to the above phenomenon, we can initially conclude that it is a fake.
5 Many mobile phone manufacturers have also made efforts to improve their know-how and make counterfeiting of mobile phones and accessories more difficult from their own perspective, thereby further curbing the proliferation parallel and counterfeit imports. Generally, ordinary mobile phone products and their accessories should have a consistent appearance.
So when we install the battery of the cell phone we bought, should we carefully compare the body and the bottom case of the battery? If the color matches, it is an original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery.
6 Observe load anomalies. Generally, genuine cell phone batteries must haveThere is an overcurrent protector inside, which automatically cuts off the circuit when an external short circuit causes excessive current to avoid burning or damaging the phone. Lithium-ion batteries also have an overcurrent protection circuit, which can be; used when non-standard electrical appliances are used.
When the power current is too large, the power will be automatically cut off, resulting in charging failure. When the battery is normal, it can automatically return to the conductive state. If during the charging process we find that the battery seriously overheats, smokes or even explodes, it means that the battery must be fake.

How to identify whether an electric vehicle battery is a lithium battery ?
Lithium-ion batteries and lithium-polymer batteries can be distinguished on the battery packaging label. Lithium-ion batteries are usually marked with the word Li-ion, and lithium-polymer batteries are. usually marked with the word Li-Polymer as shown below. At the same time, because the electrolyte of lithium polymer batteries is gel-like, there are fewer problems with electrolyte leakage, so most of them are aluminum-plastic soft packaging .
Lithium polymer batteries have the same chemical properties as liquid lithium ion batteries, and even the internal structure is the same. This is a new type of battery developed on the basis of liquid lithium-ion batteries, and. is similar to liquid lithium-ion batteries. Compared with lithium-ion polymer batteries, they have the following advantages:
Good dry performanceurity, will not explode
Can be made into various shapes
Compared to the same steel-cased lithium batteries and lighter aluminum-cased lithium batteries?
p>
The capacity is generally higher than that of lithium batteries with steel casing and lithium batteries with aluminum casing of the same specifications?
The internal resistance is small, so the Battery capacity can be maximized.
Good performance at high temperature, no bulging at 85℃ for 4 hours
p>
Good consistency in cycle performance, battery capacity and internal resistance.
I'm afraid that's impossible. But it must also be analyzed on a case-by-case basis. \x0d\I just bought an electric car recently. \x0d\At first I wanted to buy lithium batteries because they were light and fashionable, but after thinking about it carefully, I decidedidea to buy lead acid batteries. \x0d\Since lithium batteries are not suitable for high-current discharge and are very expensive, at the same capacity, their price is much higher than that of lead-acid batteries. And the light weight of lithium batteries makes the cars easy to steal. After all, heavy cars are difficult to steal. \x0d\\x0d\I saw a lithium battery folding bike priced at 1,999. It obviously uses lithium batteries and is very cheap. The weight is only 9.5 kg. This looks perfect. But if you take a closer look, you will find that its cruising range is only 20 km. \x0d\Because lithium batteries are expensive, it is very expensive to get the same capacity as lead-acid batteries, so the battery is indeed a lithium battery, but the capacity has decreased. \x0d\\x0d\The biggest difference between lithium batteries and lead acid batteries is that they are lightweight. Ramasknow it and you will know. \x0d\Too cheap lithium batteries are very dubious and can be easily damaged.
