1、What is the technology behind Yinlong's lithium titanate.
According to Yinlong's own statement,lithium titanate batteries have the longest lifespan and highest safety among lithium batteries.In terms of lifecycle,ordinary lithium-ion batteries have about 1000-2000 cycles,while lithium titanate has 10000-20000 cycles.Yinlong has announced that it has mastered the world's leading lithium titanate core technology,achieving 6-minute fast charging and a 30-year cycle life.
Ordinary lithium batteries use lithium containing materials as the positive electrode and graphite as the negative electrode.However,the voltage of lithium titanate is too low,and using lithium titanate as a positive electrode results in a very poor capacity.So the usual approach is to use lithium titanate as the negative electrode and another lithium containing material as the positive electrode.
The so-called long cycle life of lithium titanate is a false proposition,because batteries cannot be used only if the negative electrode life is long,and the positive electrode life also needs to be long.The lifespan of the positive electrode of a lithium battery depends on the positive electrode material.
Among the three commonly used materials,lithium cobalt oxide,ternary materials,and lithium iron phosphate,lithium iron phosphate has the longest lifespan.So lithium titanate is usually combined with lithium iron phosphate to make batteries.
The battery capacity of lithium iron phosphate positive electrode and graphite negative electrode is not large,and the capacity of lithium titanate negative electrode is even lower.
So,the energy density of lithium titanate batteries is relatively low among lithium batteries,which is its fatal disadvantage.
In addition,lithium titanate reacts with electrolytes and produces gas after a certain number of uses,resulting in a short actual lifespan.So although Panasonic has been making this thing for a long time,it has never developed.
The work done by Yinlong is to effectively suppress the gas generation reaction at the interface between lithium titanate and electrolyte through graphene doping coating technology,which avoids the occurrence of"gas swelling"phenomenon and truly prolongs the lifespan.
The lithium iron phosphate in the positive electrode is originally a long-life material,and the lithium titanate in the negative electrode solves the problem of gas release.The lifespan issue of Yinlong's lithium titanate has been resolved.
As for the problem of poor performance and low energy density,it cannot be solved.When used in a family car,it needs to be charged once a day for commuting,and no one can stand it.
However,Yinlong Group has found a suitable market for lithium titanate by utilizing its long lifespan and fast charging characteristics-buses.
Buses are large and have low energy density,they only need to carry a few hundred kilograms of batteries.And it charges quickly,allowing for quick recharging between bus departures.It can quickly replenish power and has a long lifespan,which other solutions cannot achieve.
In addition,lithium titanate has additional small advantages,firstly,its low-temperature performance is better than other batteries.The second reason is that the negative electrode is not graphite,and the probability of lithium metal crystals piercing the separator is smaller,making it safer.
So,lithium titanate is a lithium battery technology that is only suitable for buses or special vehicles(airport buses,internal logistics vehicles,non long-distance delivery vehicles with charging sites).Both strengths and weaknesses are evident.
2、The commercial value of Yinlong lies in government orders
Because the positive electrode of lithium titanate batteries is lithium iron phosphate,the negative electrode is lithium titanate,and nano technology is used for lithium titanate,the price is relatively expensive.
Due to its low energy density,a bus requires a lot of usage,so the overall price of the bus is also very expensive.
If there were no government subsidies,even at the end of its lifespan,this type of car would have no market competitiveness.
However,China had a generous new energy subsidy policy before 2020,providing unbelievably high subsidies for buses and coaches.This subsidy standard once reached an absurd level(according to the length subsidy,the subsidy far exceeds the cost of car manufacturing).
So,there were a large number of fraudulent compensation incidents in various places,and the Ministry of Finance found almost no clean companies.Finally,several typical companies were announced as a warning to others.
However,despite the investigation and punishment,the companies involved in the production of Zhengbajing cars still receive generous subsidies.This gives Yinlong the opportunity to develop.
Stimulated by subsidy policies,Beijing Public Transport has signed a large contract with Yinlong,and the bus has already been on the road in Beijing,with a good response.
From the current industry chain,although Yinlong's technology is very suitable for some special fields,the high price is a barrier.Without subsidies,the market will not be very large.For a long time,Yinlong could not do without state subsidies,and it is difficult to say what will happen after the current subsidy policy until 2020.
So,the current commercial value of Yinlong only lies in government orders.Once there is no subsidy and the cost cannot be reduced,the future of lithium titanate is relatively uncertain.
3、IPO or its true purpose
From the current technology perspective,the prospects for subsidies such as Yinlong are not optimistic after they expire.But capital doesn't necessarily have to wait until commercial value is realized to make money.The biggest profit is not in the automotive market,but in the capital market.
Originally,Gree's acquisition of Zhuhai Yinlong was equivalent to taking over Gree's shell.Gree opposed it,so Zhuhai Yinlong planned to go public on its own,or IPO,or shell borrow.Dong Mingzhu is likely to be deeply involved.From the situation where big players such as Wanda,CIMC,and JD.com have taken action,the probability of successful IPO or backdoor listing is not small.
There are even reports that this collective capital increase and investment is a Pre IPO,and the situation has reached a considerable level.
So,the real purpose of this investment may be to take advantage of the country's support policies in the field of new energy,obtain certain conveniences,such as backdoor or IPO,and allow investors to profit from the secondary market.
