18650 battery rechargeable

The world's first CTP 18650 battery rechargeable pack. How to deal with the traditional PACK process?

The de-modularized CTP 18650 battery rechargeable pack is about to achieve large-scale installation and application.

In terms of energy density, the average energy density of traditional 18650 battery rechargeable packs is 140-150Wh/kg, while the energy density of CTP 18650 battery rechargeable packs can reach more than 200Wh/kg.

CATL and BAIC New Energy jointly developed the first CTP 18650 battery rechargeable pack, which is a manifestation of the strong alliance. It also shows that CTP technology has been recognized by first-tier OEMs, laying the foundation for the large-scale installation and application of CATL's CTP 18650 battery rechargeable packs.

At present, CATL's customers include first-tier OEMs at home and abroad. It may develop CTP 18650 battery rechargeable packs for other passenger cars in the future, which will help deepen its strategic cooperation with OEMs and further increase CATL's power 18650 battery rechargeable market share.

Judging from the PACK technology roadmap of CATL in recent years, CATL has continued to optimize cell size and PACK structure design to achieve an increase in system energy density.

At the cell level, we are moving from the original VDA size to large cells, with larger and larger sizes and higher capacities.

In terms of modules, CATL's design has also developed from standardized modules to large modules and no modules, trying to reduce the weight of modules and achieve iterative upgrades of modules.

Obviously, CATL’s design evolution in 18650 battery rechargeable cells and modules represents the development direction of domestic power 18650 battery rechargeable pack technology. The design ideas of other 18650 battery rechargeable companies are also similar to CATL, with the purpose of increasing energy density and reducing costs. CATL took the lead in developing CTP 18650 battery rechargeable packs, which further reflects its technical level in the field of power batteries.

In order to further enhance market competitiveness, OEMs may give priority to CTP 18650 battery rechargeable packs for matching when developing and designing new models. This will encourage other 18650 battery rechargeable companies to follow up and launch CTP 18650 battery rechargeable packs, which may change the competitive landscape of the domestic power 18650 battery rechargeable market in the future. .

Gaogong Lithium 18650 battery rechargeable has learned that the current first-line OEMs and mainstream 18650 battery rechargeable companies generally recognize the optimization role of CATL's CTP technology in improving energy density and volume utilization and reducing costs.

In addition to CATL, 18650 battery rechargeable companies including BYD, Honeycomb Energy and other 18650 battery rechargeable companies are also developing CTP 18650 battery rechargeable packs, and more 18650 battery rechargeable companies may launch CTP 18650 battery rechargeable packs in the future.

In addition, in addition to BAIC New Energy, Chery New Energy is also cooperating with CATL to develop CTP 18650 battery rechargeable packs, which will soon undergo verification testing to prepare for large-scale introduction and application in the future.

In fact, under multiple pressures such as declining subsidies and intensifying market competition, OEMs have put forward higher requirements for 18650 battery rechargeable companies in terms of cost reduction and product performance improvement.

For 18650 battery rechargeable companies, the most direct way to reduce 18650 battery rechargeable manufacturing costs and increase energy density is to optimize the 18650 battery rechargeable manufacturing process and material system.

The former mainly optimizes and upgrades cell size, PACK structure design and automated production to improve cell yield and reduce manufacturing costs.

The latter's focus is on developing high-nickel, cobalt-free or developing next-generation new materials, and optimizing the material system to reduce 18650 battery rechargeable costs and improve product performance.

It is worth noting that once CTP 18650 battery rechargeable packs become the mainstream of the market, they may have an impact and challenge on a large number of current power 18650 battery rechargeable companies and third-party PACK companies, including OEMs.

If CTP 18650 battery rechargeable packs become mainstream, it will greatly compress the market share of traditional PACK 18650 battery rechargeable packs, and some 18650 battery rechargeable companies and PACK companies that do not have competitive strength in terms of technical strength and customer structure will be eliminated.

GGII statistics show that the current market share of third-party PACK companies is far lower than that of 18650 battery rechargeable companies and OEMs. OEMs have become the main force in PACK installations, and the products shipped by 18650 battery rechargeable companies have gradually shifted from previous 18650 battery rechargeable packs to 18650 battery rechargeable cells. .

And due to the use of de-modularization, this means that there is a huge difference from the traditional PACK process, which also places high demands on the 18650 battery rechargeable companies themselves.

However, no matter which technical route is adopted, 18650 battery rechargeable companies should put the safety of batteries first, and cannot sacrifice safety to achieve cost optimization and energy density improvement. Otherwise, there will be serious consequences and a fatal blow to the new energy automobile industry. .

Let’s take a look at what new technologies and applications there are in the power 18650 battery rechargeable industry this week.

1. Corvus and Kawasaki Heavy Industries cooperate to develop ship 18650 battery rechargeable system

Foreign media reported that Canadian ship 18650 battery rechargeable supplier Corvus Energy and Kawasaki Heavy Industries (KHI) have reached a technology licensing agreement. The two parties will jointly develop and produce new lithium 18650 battery rechargeable energy storage systems based on the new lithium-ion capacitor (LiC) technology developed by KHI. Applications in the field of electric ships. The product is expected to be available in 2020.

It is understood that LiC incorporates lithium-ion capacitor batteries into an energy storage system with efficient liquid cooling that maintains optimal temperature ranges at very high RMS currents and charge/discharge rates.

LiC will safely maintain 600 C peak and 300 C continuous charge/discharge rates, enabling energy recovery/storage and rapid discharge to handle high-power loads.

2. Blockchain technology prevents “bloody” batteries from entering the market

Foreign media reported that BMW Group, BASF, Samsung SDI and Samsung Electronics jointly launched a plan called "Cobalt for Development" to promote the sustainability and transparency of cobalt product supply by cobalt mining companies in the Democratic Republic of the Congo. .

Currently, about two-thirds of the world's cobalt supply comes from the Democratic Republic of the Congo, with at least 20% of the cobalt mined by locals such as children, and the remainder produced by industrial mines. The use of child labor in mining has often attracted the attention of international human rights organizations in the past.

3. Tata launches new powertrain technology Ziptron

Foreign media reported that Tata Motors announced the development of a new powertrain technology - Ziptron. The technology includes a high-efficiency permanent magnet AC motor and a dust- and water-resistant lithium-ion 18650 battery rechargeable system that meets IP67 standards.

Shailesh Chandra, head of Tata Motors' electric vehicle division, said the company plans to provide an eight-year warranty on future electric motors and 18650 battery rechargeable systems, and that the new powertrain system will solve the problem of range anxiety in cars. Electric vehicles using Ziptron technology have a cruising range of up to 250km.
