Den 9. Januar, um “2020NIODay” ofgehalen vum Weilai, nieft dem offiziellen Debut vum ET7, deen als “aktuell fortgeschratt Technologieintegratioun” bekannt ass, gouf och ugekënnegt datt de Weilai ET7 mat Solid-State Batterien ausgestatt ass. wäert am véierte Quartal 2022 sinn. Um Maart erreecht seng Energiedicht 360Wh / kg, a mat Solid-State Batterien kann de Kilometer vun der Weilai ET7 méi wéi 1,000 Kilometer op enger eenzeger Ladung erreechen.

However, Li Bin, the founder of Weilai, was silent on the supplier of solid-state batteries, saying only that Weilai Automobile has a very close cooperative relationship with solid-state battery suppliers and is definitely the industry’s leading company. Based on Li Bin’s words, the outside world suspects that this solid-state battery supplier is likely to be in the Ningde era.

Awer egal wien NIO’s Solid-State Batterie Fournisseur ass, Solid-State Akkuen sinn déi bescht Léisung fir vill Problemer an der Entwécklung vun neien Energie Gefierer, a si sinn och eng wichteg Entwécklung Richtung an der Muecht Batterie Industrie.

A person in the power battery industry believes that solid-state batteries will be the technological commanding heights of the next generation of high-performance power batteries. “The field of solid-state batteries has entered the stage of an’arms race’ with many market participants, including car companies, power battery companies, investment institutions, and scientific research. Institutions and others are playing games in the three aspects of capital, technology, and talent. If they don’t seek change, they will be out of the game.”

Power Batterie op der ganzer Welt

D’Heizung an d’Ofkillung vun der Kraaftbatterieindustrie sinn onseparabel vun der neier Energie Autosindustrie, a mat der gradueller Erhuelung vum neien Energieautomaart ass d’Konkurrenz an der Kraaftbatterieindustrie ëmmer méi haart ginn.

It is worth mentioning that the power battery is known as the “heart” of new energy vehicles, accounting for 30% to 40% of the cost of the vehicle. For this reason, the power battery industry was once considered a breakthrough point in the next era of the automotive industry. However, with the cooling of policies and the return of foreign brands, the power battery industry is also facing the same severe challenges as the new energy automobile industry.

D’Ningde Ära war déi éischt mat schwéieren Erausfuerderungen.

Den 13. Januar huet südkoreanesch Maartfuerschungsorganisatioun SNEResearch relevant Donnéeën iwwer de weltwäite Power Batterie Maart an 2020 ugekënnegt. Date weisen datt am Joer 2020 déi global installéiert Kapazitéit vu Stroumbatterien op elektresch Gefierer 137GWh erreechen, e Joer-op-Joer Erhéijung vun 17%, vun deem CATL fir d’véiert Joer hannereneen de Championnat gewonnen huet, an d’Joer installéiert Kapazitéit erreecht 34GWh, eng Joer-op-Joer Erhéijung vun 2%.

For power battery companies, the installed capacity determines their market position. Although the installed capacity of the CATL still maintains an advantage, from the perspective of the increase in global business growth, the installed capacity of the CATL is far lower than the global growth rate. In doubt, Japanese and Korean power battery companies represented by LG Chem, Panasonic, and SKI are rapidly expanding.

Zënter datt déi nei Energieauto Subventiounspolitik am Joer 2013 offiziell agefouert gouf, huet d’Kraaftbatterieindustrie, déi enk mat der neier Energie Gefierindustrie verbonnen ass, eng séier Entwécklung agefouert.

No 2015 huet de Ministère fir Industrie an Informatiounstechnologie Politikdokumenter erausginn wéi “Automotive Power Battery Industry Standards and Standards” an “Power Battery Manufacturers Directory”. Japanesch a südkoreanesch Kraaftbatteriefirmen goufen “ausgedréckt”, an d’Entwécklung vun der Gewalt Batterieindustrie erreecht säin Héichpunkt.

However, in June 2019, with tightened policies, higher thresholds, and changes in routes, a large number of power battery companies experienced a period of struggle and eventually disappeared. By 2020, the number of domestic power battery companies has been reduced to more than 20.

Zur selwechter Zäit sinn auslännesch investéiert Stroumbatteriefirmen scho laang bereet fir d’Fett op de chinesesche Maart ze bewegen. Zënter 2018 hunn japanesch a koreanesch Kraaftbatteriefirmen wéi Samsung SDI, LG Chem, SKI, asw. Ënnert hinnen sinn d’Kraaft Batterie Fabriken vu Samsung SDI a LG Chem ofgeschloss an a Produktioun gesat. Den Hauskraaftbatteriemaart Presentéiert den “Three Kingdoms Killing” Muster vu China, Japan a Südkorea.

The most aggressive is LG Chem. Since the Model 3 series produced by Tesla’s Shanghai Gigafactory uses LG Chem batteries, it has not only driven the rapid growth of LG Chem, but also blocked the Ningde era. In the first quarter of 2020, LG Chem, which originally ranked third, surpassed the Ningde era in one fell swoop and became the world’s largest power battery company with market share.

Zur selwechter Zäit huet BYD och eng Offensiv lancéiert.

In March 2020, BYD released blade batteries and began supplying them to third-party car companies. Wang Chuanfu said, “Under the grand strategy of full opening up, the independent split of BYD Battery has been put on the agenda, and it is expected to conduct an IPO around 2022.”

Tatsächlech sinn d’Bladebatterien méi iwwer Verbesserungen an der Batterieproduktioun a Veraarbechtungstechnologie, a keng Duerchbroch Innovatiounen a Materialien an Technologie. Am Moment sinn déi ternär Lithium Batterie a Lithium Eisenphosphat Batterie allgemeng an elektresche Gefierer benotzt souwuel Lithium-Ion Batterien, an d’Lithium Batterie mat der héchster Energiedicht ass 260Wh / kg. D’Industrie gleeft allgemeng datt d’Energiedicht vu Lithium-Ion Batterien no un der Limit ass. Et ass schwéier 300Wh / kg ze iwwerschreiden.

Déi zweet Halschent Kaartespill huet ugefaang

An undeniable fact is that whoever can break through the technical bottleneck first will be able to seize the opportunity in the second half.

As early as December 2019, the Ministry of Industry and Information Technology released the “New Energy Vehicle Industry Development Plan (2021-2035)”, which included accelerating the R&D and industrialization of solid-state power battery technology as a “New Energy Vehicle Core Technology Research Project”. Promote the solid-state battery to the national strategic level.

In recent years, mainstream automobile companies at home and abroad, such as Toyota, Nissan Renault, GM, BAIC, and SAIC, have begun to step up the R&D and industrialization of solid-state batteries. At the same time, battery companies such as Tsingtao Energy, LG Chem, and Massachusetts Solid Energy Preparations for the construction of solid-state battery factories have also begun, including solid-state battery production lines that have already been put into operation.

Am Verglach mat traditionelle Lithium-Batterien hunn Solid-State Batterien vill Virdeeler wéi méi héich Energiedicht, besser Sécherheet a méi kleng Gréisst, a gi vun der Industrie als Entwécklungsrichtung vu Kraaftbatterien ugesinn.

Unlike lithium batteries that use electrolytes as electrolytes, solid-state battery technology uses solid glass compounds made of lithium and sodium as conductive materials. Since the solid conductive material does not have fluidity, the problem of lithium dendrites is naturally solved, and the intermediate diaphragm and the graphite anode material to ensure stability can be removed, saving a lot of space. In this way, the proportion of electrode materials can be increased as much as possible in the limited space of the battery, thereby increasing the energy density. In theory, solid-state batteries can easily achieve an energy density of more than 300Wh/kg. This time Weilai claims that the solid-state batteries it uses have achieved an ultra-high energy density of 360Wh/kg.

The above-mentioned industry insiders also believe that this battery will be an important step towards the future of electrification. The energy density of solid-state batteries is expected to reach two to three times that of current lithium-ion batteries, and will be lighter, longer life, and safer than current batteries.

D’Sécherheet war ëmmer e Schied iwwer d’Batterieindustrie.

Am Joer 2020 huet mäi Land insgesamt 199 Autoen zréckruffen, mat 6,682,300 Gefierer, vun deenen 31 nei Energie Gefierer zréckgeruff goufen. Am Recycling vun neien Energieautoen kann d’Energiebatterie potenziell Sécherheetsrisiken hunn wéi thermesch Flucht a Spontanverbrennung. Et ass nach ëmmer de Recycling vun neien Energieautoen. Haaptgrond. Am Géigesaz, ass déi gréissten Feature vu festen Elektrolyte datt se net einfach ze verbrennen sinn, an doduerch d’Sécherheet vun neien Energieautoen grondsätzlech verbesseren.

Toyota entered the field of solid-state batteries very early. Since 2004, Toyota has been developing all-solid-state batteries and has accumulated first-hand solid-state battery technology. In May 2019, Toyota exhibited samples of its all-solid-state battery that is in the trial production stage. According to Toyota’s plan, it plans to increase the energy density of solid-state batteries to more than twice the energy density of existing lithium batteries by 2025, which is expected to reach 450Wh/kg. By then, electric vehicles equipped with solid-state batteries will have a significant increase in cruising range, which is comparable to current fuel vehicles.

Zur selwechter Zäit huet BAIC New Energy och d’Réalisatioun vun der Inbetreiung vum éischte reng elektresche Prototyp Gefier ugekënnegt, deen mat engem Solid-State Batteriesystem ausgestatt ass. Am Ufank vum 2020 huet BAIC New Energy den “2029 Plang” ugekënnegt, deen de Bau vun engem diversifizéierten Energiesystem mat engem “Dräi-an-eent” Energie Drive System vu Lithium-Ion Batterien, Feststoffbatterien a Brennstoff enthält. Zellen.

Fir dës kommend hefteg Schluecht huet d’Ningde Ära och en entspriechende Layout gemaach.

Am Mee 2020 huet den Zeng Yuqun, President vum CATL, verroden datt richteg Solid-State Batterien Lithiummetall als negativ Elektrode brauchen fir d’Energiedicht ze erhéijen. CATL investéiert weider a modernste Fuerschung a Produkt R&D an Solid-State Batterien an aner Technologien.

Obviously, in the field of power batteries, a jamming battle based on solid-state batteries has quietly kicked off, and the technological leadership based on solid-state batteries will become a watershed in the field of power batteries.

Solid-State Batterien sinn nach ëmmer mat Schakelen

According to SNEResearchd’s calculations, my country’s solid-state battery market space is expected to reach 3 billion yuan in 2025 and 20 billion yuan in 2030.

Trotz dem grousse Maartraum ginn et zwee grouss Probleemer mat Solid-State Batterien, Technologie a Käschten. Am Moment ginn et dräi Haaptmaterialsystemer fir zolidd Elektrolyte a Feststoffbatterien op der Welt, nämlech Polymer ganz zolidd, Oxid ganz fest, a Sulfid ganz zolidd Elektrolyte. Déi zolidd-state Batterie, déi vum Weilai erwähnt ass, ass tatsächlech eng semi-solid Batterie, dat heescht, flësseg Elektrolyt a Mëschung vun oxid festen Elektrolyte.

From the perspective of mass production possibilities, solid-state batteries can indeed solve the current safety issues of liquid batteries. However, because the conductivity of the first two material systems is a theoretical problem rather than a process problem, it still needs a certain amount of R&D investment to solve it. In addition, the “production hazards” of the sulfide system cannot be effectively dealt with temporarily. And the cost problem is bigger.

De Wee fir d’Industrialiséierung vu Solid-State Batterien ass ëmmer nach dacks verstoppt. Wann Dir wierklech d’Energiedichte Bonus vu Feststoffbatterien wëllt genéissen, musst Dir de Lithiummetall negativ Elektrodensystem mat méi héijer Energiedicht ersetzen. Dëst kann duerch d’Sécherheet vun Solid-State Batterien erreecht ginn, an d’Batterie Energie Dicht kann iwwer 500Wh / kg erreechen. Awer dës Schwieregkeet ass nach ëmmer ganz grouss. D’Fuerschung an d’Entwécklung vu Solid-State Batterien ass nach ëmmer an der Laboratoire wëssenschaftlecher Experimentstadium, déi wäit vun der Industrialiséierung ass.

E Beispill dat kann zitéiert ginn ass datt am Mäerz 2020 Nezha Motors en neie Modell vun Nezha U verëffentlecht huet mat Solid-State Batterien ausgestatt. Laut Nezha Motors, plangt Nezha U am Oktober d’lescht Joer dem Ministère fir Industrie an Informatiounstechnologie ze mellen. 500 Sets gi produzéiert. Wéi och ëmmer, bis elo feelen nach ëmmer 500 Nezha Solid-State Batterie Autoen.

However, even if solid-state batteries have mature technology, mass production still needs to solve the cost competition with liquid lithium batteries. Li Bin also said that the difficulty of mass production of solid-state batteries is that the cost is too high, and the cost problem is the commercialization of solid-state battery technology. The biggest challenge.

Am Wesentlechen sinn d’Cruiseberäich an d’Benotzungskäschte (d’Käschte vum ganze Gefier an d’Ersatzbatterie) nach ëmmer déi schwaach Linke vun elektresche Gefierer, an den Erfolleg vun all neier Technologie muss dës zwee grouss Problemer zur selwechter Zäit léisen. Laut Berechnungen sinn d’Gesamtkäschte vun enger Solid-State Batterie, déi och eng Graphit negativ Elektrode benotzt, 158.8 $ / kWh, wat 34% méi héich ass wéi d’Gesamtkäschte vun enger flësseger Batterie vun 118.7 $ / kWh.

Insgesamt sinn Solid-State-Batterien nach an enger Iwwergangsstadium, an technesch a Käschte-Problemer mussen dréngend geléist ginn. Trotzdem, fir d’Muecht Batterie Industrie, Solid-State Batterien sinn nach ëmmer den héije Buedem an der zweeter Halschent vum Spill.

Eng nei Ronn Batterie Technologie Revolutioun kënnt, a kee wëll an der zweeter Halschent vun der Schluecht hannertenee falen.
