A reader friend sent me an inexplicable post and asked me what I thought.
It reads as follows:
At this time, the promotion of semi-solid vehicle batteries is playing with words!
How to understand this sentence?
It's hard to decipher.
First of all, the "word game" is nothing more than an allusion to the semi-solid vehicle battery (power battery) is false and unreliable, and secondly, it is not difficult to interpret when "this time" is afraid, and new energy vehicle manufacturers are in full swing in the price war. It seems that the meaning of this sentence is that semi-solid-state batteries should not be talked about in the stage of involution, but why can't they be said? At the same time, the so-called "playing word games" can not be agreed, because semi-solid power batteries have been accelerating the loading, and there are no less than ten power battery manufacturers or automobile manufacturers that disclose the progress of semi-solid-state battery loading.
The author does not think that the whole industry is wrong, but BYD's joint venture brand Denza Automobile executives "wake up", now BYD mainly focuses on lithium iron phosphate batteries, which is its so-called "blade battery"; However, there is still a certain gap between the energy density and thermal runaway limit of ternary lithium batteries using liquid electrolytes and power batteries using semi-solid electrolytes mixed with solids and liquids.
Therefore, the application and industrial scale of semi-solid-state batteries can play a role in accelerating the macro strategy of the entire automobile electrification, and BYD does not know whether to engage in semi-solid-state power batteries, but whether it engages in this battery or not will not affect the progress of the entire industry.
Which companies are engaged in semi-solid-state power batteries and do not "hide and tuck"?
Recently, the car company that talked about semi-solid-state power batteries is SAIC Zhiji, so some netizens also think that it is "Yin Yang Zhiji L6", but SAIC is only one of the many companies engaged in semi-solid-state batteries.
Car companies that have disclosed the progress of semi-solid-state power batteries or solid-state batteries or related information are:
- NIO
- Cialis (Ask the World)
- Chang'an navy
- Dongfeng Lantu
- Liberate together
- SAIC
- GAC Group
- Geely Automobile
- Great Wall Motors
Etc.
Power battery manufacturers include Guoxuan Hi-Tech, Funeng Technology, Weilan New Energy, Qingtao Energy, etc., CATL is accelerating the investment in the research and development of solid-state batteries; among these enterprises, there are car sales and ownership of very high car companies, and there are also power battery manufacturers in the top ten in terms of power battery loading.
Semi-solid-state batteries have already begun to be used in pure electric vehicles such as the SAIC Zhiji L6, and there is no possibility of jokes here when there are already products that can be delivered to the individual user market.
The emergence of any kind of new technology products will eliminate the old technical products, once the semi-solid-state battery realizes the industrial scale, the advantages of some car companies will be swept away, but the semi-solid-state battery gradually replaces the full liquid electrolyte battery is the inevitable result, because the use of liquid electrolyte lithium-ion battery whether ternary lithium or lithium iron phosphate, it can not avoid the generation of lithium dendrites in the fast charging process.
Liquid lithium batteries will generate lithium dendrites during fast charging, and lithium dendrites will penetrate the separator and cause a short circuit in the power battery, but the semi-solid electrolyte can effectively inhibit the formation of lithium dendrites, so this power battery can further improve the safety performance of new energy vehicles, and at the same time can further improve the charging efficiency of power batteries.
Epilogue:
No matter how some car companies or individuals look at semi-solid-state batteries and all-solid-state batteries that will be popularized in the future, the progress of technology will not be stagnant because of its wrong views; a number of power battery manufacturers and first-line car companies will not all engage in word games, and the real word games are to package low-cost technical products out of the image of "tall", who is playing word games, who has a stronger ability to control the cost after forgetting the original intention of "returning the car to the use of attributes", I believe that real car users have a scale in their hearts.
