Cylindrical lithium batteries from the moment of birth to shoulder the charge on the energy storage supply, support for a variety of equipment operations. They have a variety of different sizes, of which the size of 18650 to develop the most rapidly.
However, this is a small thing, has once again affected the industry's nerves. Charging head network learned from the supply chain: Continued to rise by the impact of raw materials, LG cell phone out of stock prices, mobile power costs will rise, a number of mobile power brand shipments affected.
LG 18650 full price of the battery
Recently, the charging network was informed: As raw materials continue to rise, a company received the LG original notice, in 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.
Mobile power capacity is generally between 10000mAh-20000mAh, need to use 3-6 batteries, with a 6-cell mobile power, for example, the cost will increase 12 yuan.
So a single cell, the cost of mobile power will rise a lot, the final cost will be passed on to consumers.
Mobile power out of stock
In fact, as early as last November, the charging head network has been broke in advance LG 3350mAh 18650 batteries out of stock, a number of mobile power brand shipping affected.
For example, we learned that, Millet variety of mobile power supply shortage, such as millet portable flashlight models mobile power often out of stock, and the critically acclaimed ZMI Purple No. 10 mobile power shortly before the introduction of the battery shrunk version (from 20000mAh down to 15000mAh) , The old version of high-capacity shelves, I believe it is due to the impact of price increases this cell.
18650 cell Big Three: Panasonic, Samsung, LG. Panasonic's production to Tesla eaten, seldom sold to the mobile power market, and the recent Samsung mobile power market is relatively rare. Shortage, a direct impact on the millet, purple and many other brands of mobile power shipping.
What is 18650 batteries?
18650-type batteries, using Cylindrical cylindrical package, this battery diameter 18mm, length 65mm, are widely used in mobile power, electric cars, laptops, flashlights and other fields.
The benefits of this package is uniform specifications, 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 technology is changing rapidly, however Battery development has not ushered in the leap of Moore's Law, the energy density slowly increased only very slowly 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 of mobile power batteries and raw materials.
Previously, Roland Berger, a world-renowned strategic management consulting firm, released the report "Global Electric Vehicle Development Index for the Second Quarter of 2017". China made its first position in the EV ranking in the world for the first time.
China has become the 'main battlefield' for electric car makers that the world's auto giants such as Tesla and other electric cars rush into the market. The encouragement policies such as government subsidies also play a certain role in promoting the development of new-energy vehicles in China.
This trend of development will bring huge demand for batteries, and will undoubtedly give serious impact on the production capacity and raw materials of mobile power batteries.
In addition, some of the batteries in the metal and other raw materials in the global reserves is limited.With the rapid growth in demand, raw materials become in short supply. It is estimated that by 2019, the indispensable raw materials such as metallic lithium and cobalt will continue to be tight, and the corresponding prices are under upward pressure.
Batteries out of stock prices this situation is expected to exist for a long time, can not be alleviated in a short 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, the recommended 20650 batteries, 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 have these restrictions, then you can switch to lithium polymer batteries, although the cost is higher than 18650 batteries, but it does not exist out of stock, the brand will be more choice.
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.
