Tesla’s homegrown Model 3 long-life version confirms triple battery plan

Tesla’s expected domestic model 3 long-range version of the model is already on the list in the third batch of “New Energy Vehicle Promotion and Application Recommended Model Sedirectory” released recently. With the new energy vehicle battery “de-cobalt” expectations, the A-share market was once not friendly to cobalt. In mid-to-late February, the agency reported that Tesla was in talks with the Ninder era for the supply of lithium batteries, planning to use cobalt-free batteries in Chinese-made Model 3 models to replace the three-way lithium battery currently used by Tesla.

Tesla later said it currently has a co-operation agreement with the Ninder era, and that the iron phosphate lithium battery in the Ningde era is “non-cobalt-free in itself”.

Affected by this news, Huayou cobalt industry, cold cobalt industry and other cobalt mining companies share prices have been significantly adjusted. Wind data show that Huayou cobalt, cold cobalt industry since February, the highest withdrawal has reached 25.36%, 25.79 percent.

In fact, if the Ningde era based on the CTP scheme (bypassing the module directly integrated battery pack) lithium iron phosphate lithium battery, it is indeed able to achieve battery costs compared to the triple lithium battery model to achieve a reduction of more than 20%.

However, according to the 21st century economic report reporter from the Ministry of Industry and Information Technology website was informed that in the recent release of the third batch of 2020 “new energy vehicle promotion and application recommended model catalog”, Tesla is expected to domestic Model 3 long-range version has been in the list.

According to the filing information, the range of this version reached 668 kilometers, more than the previous imported version of the range of 4 kilometers, and the type of energy storage device is still identified as “three-way lithium-ion battery.”

Three-way lithium battery, is the current pure electric vehicle to pursue a higher range of solutions, Tesla and Panasonic, its 811 three-way lithium battery using nickel-cobalt aluminum (NCA) solution, while the Asian power battery suppliers, the choice of model is more nickel-cobalt manganese (NCM) solutions, such as the Ningde era and LG currently provided , using the NCM’s triple battery, but either option can not avoid the use of the precious metal “cobalt”.

Compared to the two, NCA has a higher energy density, for example, the density of the Tesla Panasonic joint venture plant is close to 300Wh/kg, while the density of the NCM battery is generally around 250Wh, but on the other hand, the NCA solution for the physical environment, production process and battery thermal management requirements are higher, so the production is more difficult, and the NCM solution is more mature and more safe.

From the above-mentioned Ministry of Industry and Information Technology filing information, has not yet put into production of Tesla’s domestic long-range model 3 will still use the three-way lithium battery program, will not completely abandon the use of “cobalt”, which also confirmed the industry’s previous lithium phosphate CTP program in the energy density of the “ceiling” of this speculation.

“Even with the CTP structure, the existing energy density may not be a complete replacement for triamcinance lithium, with the previous single-drive long-range model 3’s NECD range at more than 650 km, and car buyers have some expectations for the increase in range.” A battery industry close to Tesla has previously said, “But the CTP model has little room to continue to increase energy density without changing the material, so there will be a significant number of long-range vehicles that will need triple batteries.” “

At present, some of the domestic Tesla standard battery capacity, the use of power batteries is from LG Nanjing supply of NCM batteries, but analysts see that Tesla’s choice is mainly related to cost considerations, and in the future in the field of triuma electric batteries, there may be cooperation with the Ningde era.

Although the Ningde era has been in the global market for power battery shipments, but its limited capacity is insufficient, resulting in its triple lithium battery costs are still higher than the competition. A previous UBS report showed that Tesla’s production of batteries with Panasonic cost $111/kwh, while the cost of LG chemicals proposed for the Shanghai super factory was around $140/kwh, compared with $150/kwh for the same period.

LG’s striatum 811 battery costs lower and supply is more stable, but if the ninder era expands production and increases production capacity, the marginal cost falls, Tesla may also be working with the Ninder era on the triamcinor son. “A person close to the Ningde era said.
