1. solid state battery
Solid-state battery is a kind of battery technology. Different from the widely used lithium-ion batteries and lithium-ion polymer batteries, solid-state batteries are batteries with solid electrodes and solid electrolytes. Because the scientific community believes that lithium-ion batteries have reached the limit, in recent years, solid-state batteries have been considered as batteries 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 substance, which replaces the electrolyte of previous lithium batteries and greatly improves the energy density of lithium batteries.
2. Advantages of solid-state batteries
(1) light-high energy density. After using all-solid electrolyte, the material system suitable for lithium-ion batteries will also change. One of the key points is that it is not necessary to use lithium-embedded graphite negative electrode, but to use metal lithium directly as positive electrode, which can obviously reduce the amount of positive electrode material and significantly improve the energy density of the whole battery.
(2) Thin-small volume. In the traditional lithium-ion battery, it is necessary to use the separator and electrolyte, which together account for nearly 40% of the battery volume and 25% of the battery mass. However, if solid electrolyte (mainly organic and inorganic ceramic materials) is used, the distance between anode and cathode (traditionally filled with diaphragm electrolyte, but now filled with solid electrolyte) can even be shortened to several to ten microns, so the thickness of the battery can be greatly reduced. Therefore, all-solid-state battery technology is the only way for battery miniaturization and thin film.
(3) the prospect of flexibility. Even brittle ceramic materials, when the thickness is below millimeter level, often can bend, and the material will become flexible. Accordingly, the flexibility of all-solid-state batteries will be obviously improved after thinning. By using suitable packaging materials (non-rigid casing), the battery can withstand hundreds to thousands of bends, thus ensuring that the performance is basically not attenuated.
(4) It is safer. Traditional lithium batteries may have the following dangers: lithium dendrites may appear when working at high current, which may break through the diaphragm and cause short circuit damage; Electrolyte is an organic liquid, which will aggravate the tendency of side reaction, oxidative decomposition, gas production and combustion at high temperature. All solid-state battery technology can directly solve the above two problems.

When will Huineng solid-state batteries start mass production?
In recent ten years, with the progress of the times and the vigorous development of new energy vehicles, enterprises from all sides have launched a fierce struggle between technology and production around the industrial ecological chain, and power batteries are the top priority in the blueprint of the government and car-making forces. In order to improve energy density and safety, in addition to developing high-activity anode materials under the existing lithium battery technology framework, entrepreneurs are investing in the field of solid-state battery research and development at no cost, hoping to create absolute advantages through absolute safety. Whoever has the opportunity to develop truly commercialized and mass-produced solid-state batteries will compete for the next generation of new energy vehicles.
In fact, as early as 12, Huineng Technology released a flexible thin solid-state battery ── FLCB (Flexible Solid-State Battery), which won over 100 million US dollars of investment from well-known investment institutions such as Softbank China and Feng Dan Capital. /kloc-began mass production of solid-state batteries in 0/4, supplied HTC, and applied the products to smart wearable products such as belts and helmets, and then entered the smart card and Internet of Things markets. /kloc-in 0/6, 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 requirements for battery capacity and electrical performance, and completed the second generation technology in 17, changing the original first-generation pure solid electrolyte into the second-generation mixed solid electrolyte, and applying high-energy ternary cathode active materials, silicon-carbon cathode materials and other special additives, not only the energy density was greatly improved, but also the conductivity and charge-discharge ability were simultaneously improved, so that the electrical performance of the second-generation lithium ceramic battery was all improved. In addition, Huineng released a breakthrough mechanism design based on the advantages of solid-state battery technology this year-3D packaging technology that can halve the volume, reduce the weight by 20% and reduce the cost by 30% of new energy vehicle battery packs.
Compared with most solid-state battery factories still in the research and development stage, Huineng's pioneering advantages and original second-generation technology and 3D packaging technology attract domestic, Japanese, American and European car factories to visit each other. In addition to building solid-state battery pure tram samples, it also discusses cooperation with domestic and European automobile manufacturers to build factories to produce battery cells.
