Cylindrical lithium batteries from the moment of birth to shoulder the charge of energy storage supply, supporting a variety of equipment operation. They have a variety of different sizes, of which the most rapid development of the size of 18650. However, this little thing Recently, once again affect the industry's nerves.
Charging head network learned from the supply chain: By the continuous rise of raw materials, LG cell phone out of stock prices, charging treasure costs will rise, a number of charge Bao brand shipping affected.
LG 18650 full price of the battery
Recently, the charging network was informed: As raw materials continue to rise, the company received the LG original notice, February 2018 LG 18650 full range of batteries prices will rise 15% -20% on the basis of the original.
As for the specific price, LG 3350mAh single cell original price 13RMB or so, after the price or will exceed 15 yuan.
The capacity of the rechargeable treasure is generally between 10000mAh-20000mAh, you need to use 3-6 batteries, with a 6-Charging Po, for example, The cost will directly increase 12 yuan.So a single cell, charging treasure costs will rise a lot, the final cost will be passed on to the consumers.
Charging treasure out of stock
In fact, as early as last November, the charging head network has burst in advance LG 3350mAh 18650 batteries out of stock, a number of charge Bao brand shipping affected.
For example, we learned that a variety of charging millet millet supply tension, such as millet flashlight with rechargeable models often out of stock while the well-received ZMI Purple 10 Charging Po shortly before the launch of the battery shrunk version (from 20000mAh Down to 15000mAh), large capacity of the old version of the shelves, I believe it is due to the impact of price increases this cell.
18650 batteries three giants: Panasonic, Samsung, LG. Panasonic's production to Tesla eaten, seldom sold to charge Po market, while the Samsung batteries in the recent charging treasure market is relatively rare. Carrying the beam of LG batteries appear Shortage, a direct impact on the millet, purple and many other brands of rechargeable treasure shipments.
What is 18650 batteries?
18650-type batteries, Cylindrical cylindrical packaging, the battery diameter 18mm, length 65mm, are widely used in rechargeable treasure, electric cars, notebooks, flashlights and other fields, the benefits of such packaging is uniform specifications and convenient automation , Large-scale production, with high mechanical strength, impact resistance, high yield characteristics;
In addition there are Prismatic square soft package, common in mobile phones and tablet PCs, the most direct benefits of such packages is thin, small size, portable.
Although the rapid development of science and technology, but the battery development has not ushered in the leap of Moore's Law, the energy density increased only slowly with a very small increase each year, foreign brands 18650 lithium battery energy density has exceeded 3500mAh mark, Panasonic Sanyo NCR18650GA, Samsung INR18650-35E, LG MJ1 Big Three are all foreign companies.
Out of stock reasons
With the rapid development of global new energy electric vehicles, it has squeezed the capacity and raw materials of rechargeable batteries.
Previously, Roland Berger, the world's leading strategic management consulting firm, released the report "Global Electric Vehicle Development Index for the Second Quarter of 2017." China made its first global ranking in the EV development rankings, making China the world's largest automaker and Tesla Star-influx of electric car companies 'main battlefield', government subsidies and other encouragement policies also play a certain role in promoting China's new energy vehicles are showing rapid development.
This trend of development will bring huge demand for batteries, there is no doubt that will give a serious divestment charge Po core production capacity and raw materials.
In addition, some of the batteries in the metal and other raw materials in the global reserves is limited.As the rapid growth in demand, raw materials become in short supply.
It is estimated that by the year 2019, the indispensable raw materials such as metallic lithium and cobalt will continue to be tight, and the corresponding prices will face increasing pressure. The situation of the out-of-stock prices of batteries is expected to exist for a long time and can not be alleviated in a short period of time.
solution
You can consider other alternative brand batteries, such as domestic brands of batteries. Previously due to technical relations, the domestic battery manufacturers can only 2000mAh, 2500mAh these two low-density specifications for the market.
But after many years of hard work catching up, many domestic battery factory into the 3350mAh high energy density market, with the ability to compete directly with foreign manufacturers for the market, the gap between the two further narrowed.In addition, Recommended 20650 batteries, a single 3350mAh for only 9 yuan, cost-effective.
Of course, you can switch to lithium polymer batteries, although the cost will be higher.Some products on the market by the shape and volume constraints, such as the main portable compact lipstick mobile power supply, limited by the shape can only be used 18650 batteries.If the product does not exist Limit, so much can use lithium polymer batteries, although the cost is higher than the 18650 batteries, but it does not exist out of stock, the brand choice will be more.
Of course, the best solution is to look forward to a breakthrough lithium battery technology and access to large-scale commercial, but in the short term, this is impractical.
