1. Solid-state battery
Solid-state battery is a type of battery technology. Unlike currently widely used lithium-ion batteries and lithium-ion polymer batteries, solid-state batteries are batteries that use solid electrodes and solid electrolytes. Because the scientific community believes that lithium-ion batteries have reached their limits, solid-state batteries have been considered in recent years to be the battery that can inherit the status of lithium-ion batteries. Solid-state lithium battery technology uses a glass compound composed of lithium and sodium as a conductive material to replace the electrolyte of previous lithium batteries and greatly improve the energy density of lithium batteries.
2. Advantages of solid-state batteries
(1) Light - high energy density. After using all-solid electrolytes, the material system suitable for lithium-ion batteries will also change. One of the core points is that there is no need to use lithium-embedded graphite negative electrodes, but directly use metallic lithium as the negative electrode, which can significantly reduce the amount of negative electrode materials and significantly increase the energy density of the entire battery.
(2) Thin - small size.
In traditional lithium-ion batteries, separators and electrolytes are required, which together account for nearly 40% of the battery's volume and 25% of its mass. But if solid electrolytes (mainly organic and inorganic ceramic materials) are used instead, the distance between the positive and negative electrodes (traditionally filled with separator electrolytes, now filled with solid electrolytes) can even be shortened to a few to ten microns, so that the battery The thickness can be greatly reduced - therefore, all-solid-state battery technology is the only way to miniaturize and thin batteries.
(3) The prospect of flexibility. Even brittle ceramic materials can often bend and become pliable when their thickness is below the millimeter level. Correspondingly, the flexibility of all-solid-state batteries will be significantly improved after they are made lighter and thinner. By using appropriate encapsulation materials (not rigid shells), the resulting battery can withstand hundreds to thousands of bends without substantially degrading performance.
(4) Safer. Traditional lithium batteries may have the following dangers: lithium dendrites may appear when operating at high current, piercing the diaphragm and causing short-circuit damage; the electrolyte is an organic liquid, which will intensify side reactions, oxidative decomposition, gas generation and combustion at high temperatures. tendency. Using all-solid-state battery technology can directly solve the above two problems.

When will Huineng solid-state batteries begin mass production?
In the past ten years, with the advancement of the times and the vigorous development of new energy vehicles, companies from all parties have developed around the industrial ecological chain. This has led to a fierce battle between technology and production, and power batteries are a top priority in the blueprint of the government and car-making forces. In order to improve energy density and safety, battery manufacturers, in addition to developing highly active anode materials under the existing lithium battery technology architecture, entrepreneurs are investing in solid-state battery research and development regardless of cost, hoping to create absolute safety through absolute safety. Whoever has the opportunity to develop a solid-state battery that is truly commercially available and mass-produced will be able to compete in the next generation of new energy vehicles.
In fact, as early as 2012, Huineng Technology released a bendable thin solid-state battery, FLCB (flexiblelithium Ceramic Battery), and received over 100 million US dollars in investment from well-known investment institutions such as Softbank China and Danfeng Capital. , began mass production of solid-state batteries in 2014, supplied HTC, and applied the products to smart wearable products such as belts and helmets, and then entered the smart card and IoT markets. In 2016, Huineng Technology released the first generation of solid-state battery technology. With the improvement of battery technology and production scale, Huineng Technology entered the new energy vehicle market with higher battery capacity and electrical requirements, and completed the second-generation technology in 17, changing the original first-generation pure solid electrolyte to the second-generation The first-generation mixed solid electrolyte uses high-energy ternary cathode active materials, silicon-carbon anode materials and other special additive materials at the same time. In addition to greatly increasing the energy density, it also simultaneously improves the conductivity and charge and discharge capabilities, making Huineng's second-generation lithium The electrical performance of ceramic batteries exceeds that of liquid lithium batteries. In addition, this year Huineng released a breakthrough mechanism design based on the advantages of solid-state battery technology - 3D packaging technology that can reduce the volume of new energy vehicle battery packs by half, reduce the weight by 20%, and reduce the cost by 30%.
Compared to most solid-state battery factories that are still in the research and development stage, Huineng’s first-mover advantage and original second-generation technology and 3D packaging technology have attracted domestic, Japanese, American and European car manufacturers to visit, except* **In addition to building solid-state battery pure electric vehicle samples, we are also discussing plans to cooperate with domestic and European car manufacturers to build local factories to produce battery cells.
