Svolt battery - a breakthrough in battery technology
SVOLT is a lithium battery manufacturer focusing on the R&D, production and sales of power batteries.
With its exclusive high-performance battery products and technologies, SVOLT quickly ranks among the top 10 lithium iron phosphate power battery manufacturers in China.
This article will focus on the technical breakthrough, advantages, production process, application and summary of svolt battery.
The technological breakthrough of svolt battery
Taking the short blade battery as an example, the short knife L600 electrolyte developed by SVOLT R&D personnel uses a low-viscosity solvent to improve the fluidity and conductivity of the electrolyte in a sub-zero low temperature environment.
This breakthrough effectively solves the problem that the cruising range of the Svolt battery drops sharply due to low temperature in winter.
Moreover, the researchers also added functional additives to the electrolyte, so that a polymerization reaction will occur on the lithium ion battery first charge negative electrode to form a strong protective film.
The protective film maintains stability at high temperature and does not decompose, which ensures the safety of Svolt battery in high temperature environment and greatly improves the cycle life.
In addition, the Svolt battery also uses a ceramic diaphragm with high temperature resistance and excellent insulation. It successfully passed the toughest battery tests in the industry, with no fire or smoke when a fully charged battery was pin-pricked.
Advantages of svolt battery
• Ultimate Security:
The SVOLT short blade battery adopts a “long and thin” structural design, with increased length and thinner thickness.
Compared with conventional batteries, this structural design enables the battery to generate less heat due to short-circuit triggering when the battery is subjected to external abuse (such as acupuncture), and at the same time dissipate heat faster, so that there will be no sudden temperature rise and battery fire.
The flying stacking process adopted by the Svolt battery short knife series can realize the complete compounding of the pole piece and the diaphragm, ensuring the consistency of the positive and negative reaction interfaces.
What’s more, the zero-defect manufacturing inside the product can provide higher energy density for the energy storage market.
• Extreme performance:
The number of tabs of the laminated battery is nearly twice that of the wound battery, the battery generates less heat, and the battery life is relatively longer than that of the wound battery.
The interface stability of the laminated battery at the end of the cycle is better than that of the wound battery.
SVOLT also adopts pre-lithium, flexible coating and other technologies to greatly improve energy density and cycle life.
Among them, the cycle life of the long-cycle version can reach 12,000 times, which can meet the 20-year operation requirements of the grid side.
• Extreme cost:
Achieving cost reduction and efficiency increase through extreme manufacturing is the goal that SVOLT has been pursuing.
SVOLT took the lead in introducing high-speed lamination technology into the field of prismatic batteries and continued to promote technology iterative upgrades. The efficiency and cost of manufacturing have also continued to improve.
The third-generation high-speed lamination technology adopted by SVOLT—flying lamination, has an efficiency of 0.125s/piece, saves 53% of investment per GWh, saves more than 45% of equipment unit area, and greatly reduces plant construction costs, energy costs and labor costs. cost.
The production process of svolt battery
In addition to the safety, performance, and cost advantages of Svolt batteries, the strict quality control standards of SVOLT’s car-grade battery factories are also worthy of attention.
From the control of foreign matter in the production process of battery products to the control of burrs, from the application of AI intelligent technology to the application of advanced assembly technology and integrated process, the ultimate goal is to ensure the production of high-quality battery products suitable for automotive use.
For example, the cleanliness of SVOLT’s factory building adopts the cleanliness control standard of 10,000 grades, and partially realizes 1,000 grades of control, reaching the cleanliness standard of chip-level production. In terms of humidity control, the entire process from feeding to cell sealing is controlled at 1% humidity.
Secondly, the innovation of process and technology. Through process optimization and process innovation, the SVOLTSvolt battery factory not only achieves stricter quality control of batteries, but also greatly improves manufacturing efficiency.
For example, in the extremely important rolling process, SVOLT uses positive electrode hot rolling, negative electrode double-roller continuous rolling, positive electrode rolling speed 80m/min, electromagnetic heating, infrared online baking, and online laser thickness measurement on the roller press. , waste side removal and other technology integration, and achieve higher efficiency by simplifying the process.
Third, AI intelligence is indispensable. The new generation of information technology with digitization, networking and intelligence as its core features is being deeply integrated with power battery manufacturing. In the SVOLT dagger battery factory, the application of AI technology can be seen everywhere.
