Kapital deplwaye pil solid-: men chèn endistriyèl la enpafè e plizyè pwoblèm teknik rete pou rezoud.
Dènyèman, konpayi batri solid-Huineng Technology te anonse fini yon nouvo wonn finansman 326 milyon dola ameriken; solid-konpayi batri eta Weilan New Energy te resevwa yon envestisman apeprè 500 milyon dola Yuan, ak yon valè pwojè 5 milya dola Yuan; Stellantis ak Daimler te anonse envestisman nan demaraj batri solid-FactorEnergy... Popilarite batri eta solid- kontinye ap ogmante, vin tounen yon priz envestisman pou nouvo endistri machin enèji.
Kondiktè oto ak konpayi batri goumen pou devlope
Li konprann ke pil eta solid-ranplase elektwolit la ak séparateur ak pil solid-eta, ki ka ogmante dansite enèji nan pil ityòm-yon ki egziste deja soti sou 300Wh/kg pou plis. pase 500Wh / kg, ak simonte pwoblèm tankou estabilite batri pòv ak efikasite chaje ki ba.
Kounye a, konpayi machin endikap yo ak konpayi batri yo ap fè efò pou devlope pil solid-. Pa egzanp, an 2018, Volkswagen te envesti 100 milyon dola ameriken nan QuantumScape, yon konpayi batri ityòm-yon Ameriken, pou l te vin pi gwo aksyonè a, e li te etabli yon antrepriz pou devlope batri eta solid-, ki se. yo prevwa pwodwi an mas-apre 2023; BMW planifye pou kòmanse sèvi ak pil eta solid 100AH-pou machin k ap kòmanse ane pwochèn. Tès estanda regilasyon -nivo ak entegrasyon machin, li planifye pou lanse yon pwototip veyikil ki sèvi ak batri solid-pa 2025, epi li pral aplike teknoloji batri eta solid-an mas{{13} }pwodwi machin pa 2030; Hyundai ak Kia dènyèman te anonse ansanm siyen yon akò ak FactorialEnergy pou ankouraje batri solid-. Pwodiksyon estanda nan pil; 29 novanm, Nissan te anonse lansman modèl machin elektrik ki ekipe ak tout-pil solid-nan ane fiskal 2028...
An tèm de konpayi batri, LG New Energy planifye pou komèsyalize tout-pil solid-de 2025 rive 2027; Samsung SDI planifye pou devlope gwo-echèl tout-pil solid-ak tout-solid-pwototip pwodwi batri nan eta 2025, ak mas{{ 10}}pwodwi yo an 2027; Ganfeng Lithium Industry te di, premye -jenerasyon 200 milyon Wh solid-liy pilòt batri eta a te byen mete nan pwodiksyon... Konpayi machin yo ak konpayi batri yo trè chofe pou envesti nan solid- batri leta yo, ak kèk rezilta te soti.
"It is difficult to achieve industrialization within 10 years"
Batri solid-yo gen avantaj enpòtan, men aplikasyon gwo-echèl pa ka reyalize nan yon peryòd tan kout.
Wu Hui, general manager of the Research Department of Ivey Economic Research Institute, told reporters: "Solid-state batteries are the development trend of the power lithium-ion battery industry, but some technical problems cannot be solved at present, and it is difficult to achieve industrialization within 10 years. For example, solid-state batteries are solid-state batteries. Solid interface, large internal resistance, low electrical conductivity, there is no good solution." There are three mainstream technical routes for solid-state battery electrolytes - oxides, sulfides and polymers, each with their own advantages and disadvantages. Yole Développement, a French market research company, pointed out that the key to solid-state battery applications is to find suitable electrolyte materials, and all current solutions have problems with ionic conductivity, battery life and safety.
"If the technical problems cannot be solved, the energy density advantages of solid-state batteries will not be reflected." Wu Hui said frankly.
Wu Hui further pointed out: "Actually, the 'solid-state batteries' that car companies are preparing to install are semi-solid batteries with a small amount of electrolyte." It is understood that semi-solid batteries belong to the transitional technology from liquid to solid-state batteries. For example, NIO previously announced a 150kWh solid-state battery product with a single energy density of 360Wh/kg, and the NEDC (New European Driving Cycle) cruising range of the ET7 exceeds 1,000 kilometers. The company explained that although the battery is described as a solid-state battery, it is actually a semi-solid-state battery that still requires an electrolyte and a separator.
In addition, the complex process of solid-state batteries and the lack of industrial chains have pushed up production costs. But at the same time, some research institutions believe that if solid-state batteries are mass-produced, their cost will be 40 percent of that of lithium-ion batteries. "There will be a process of cost reduction after the industrialization of solid-state batteries, but the premise is industrialization. In the future, the cost parity of electric vehicles and fuel vehicles can be achieved through the application of solid-state batteries." Wu Hui believes.

The market research institute SNEResearch estimates that by 2030, the global demand for solid-state batteries is expected to be close to 500GWh; by 2025, the global market space for solid-state batteries is expected to reach 6 billion yuan, of which my country's solid-state battery market space is expected to reach 3 billion yuan and 200 by 2030. billion. The Huaan Securities Industry Research Report pointed out that solid-state batteries have become an important breakthrough for some non-traditional battery companies to enter the lithium battery industry.
my country is the world's largest new energy vehicle market. With the advent of the TWh era, solid-state batteries have become a must for the company. The "New Energy Vehicle Industry Development Plan (2021-2035)" issued in November last year clearly proposed to accelerate the research and development and industrialization of solid-state power lithium-ion battery technology.
Wu Hui said: "Solid-state batteries are the next-generation technology direction of power lithium-ion batteries. Whether car companies or battery companies, they must be deployed, occupy the commanding heights, and first solve technical problems such as conductivity."
It is understood that as the car company with the most patents in the field of solid-state batteries, Toyota's solid-state batteries have begun to be tested in prototype vehicles. Recently, Ouyang Minggao, an academician of the Chinese Academy of Sciences, said that although my country is in a leading position in the supply of power lithium-ion batteries, companies in Europe, America, Japan and South Korea have taken the lead in the research and development of solid-state batteries, while China is still in the stage of "separate policy".
Endistri endistri yo kwè ke pri a nan batri solid-ki te soti nan premye etap la se relativman wo, epi nouvo pri a ka sèlman konpanse lè yo matche li ak modèl ki wo-. An menm tan an, yo nan lòd yo simonte difikilte yo fè fas ak komèsyalizasyon nan solid-pil eta, devlopè teknoloji, founisè ekipman, manifaktirè batri ak OEM yo bezwen travay ansanm pou ranfòse plis sipò teknik ak ranpli twou vid ki genyen nan chèn ekipman pou. . Anplis de sa, nivo nasyonal la ta dwe tou amelyore gid politik ak ankouraje kiltivasyon nan pwojè avantaje.
