On May 20, BYD launched the CTB (CelltoBody) technology for the integration of battery and body. "Compared with the traditional CTP technology, the CTB technology further integrates the battery upper cover and the body floor, and has evolved from the original battery 'sandwich' structure to the vehicle's 'sandwich' structure." Lian Yu, President of BYD Automotive Engineering Research Institute Bo said that CTB technology makes the "blade battery" more closely integrated with

Batteries are the core components of electric vehicles, energy storage power stations, and 3C products, accounting for more than 1/3 of the cost of complete vehicles and energy storage power stations. Their importance to new energy vehicles and electronic products is self-evident. The reporter learned yesterday from Innovation Workshop, a well-known domestic venture capital institution, a fully independent solution provider of intelligent design industrial software for new energy batteries. Suzhou E-Code Technology

IT House September 26 news According to foreign media TheElec news, LG Energy Solutions recently announced the development of low-temperature charging technology for solid-state batteries. The solid-state battery refers to the use of metal lithium for the negative electrode of the lithium battery, replacing the electrolyte and polymer materials containing lithium ions. This technology can significantly improve the energy density of batteries, but it has disadvantages such as difficult manufacturing and difficult ch

1. The dangers of lithium batteries Lithium battery is a potentially dangerous chemical power source from its own chemical characteristics and system composition. 1 High chemical activity Lithium is an element of the main group I of the second period of the periodic table and has extremely active chemical properties. 2 High energy density Lithium battery has extremely high specific energy (≥140Wh/kg), which is several times that of nickel-cadmium, nickel-hydrogen and other secondary batteries. If

Despite the rapid development of electric vehicles, concerns remain about the safety of lithium-ion batteries, whose dendrites have multiple branches that can cause electric vehicle batteries to catch fire. According to recent news from the official website of the American Chemical Society publication, South Korean researchers have used semiconductor technology to improve the safety of lithium batteries. A research team from the Korea Institute of Science and Technology led by Dr. Lee Joong-ki from the Energy Stora

In the context of "carbon peaking" and "carbon neutrality", accelerating the electrification of powertrains has become an inevitable trend in the development of new energy vehicles. As the key technology of new energy vehicle power system, lithium battery has become more and more prominent with the increase of energy density, and battery thermal runaway such as spontaneous combustion and explosion occurs frequently, which seriously restricts the further promotion and application of new energy ve

Analysis of lithium-ion battery technology and classification of lithium-ion battery manufacturers The lithium-ion battery technology of lithium-ion battery manufacturers is very strict and complex. Here are some important processes. Lithium-ion battery manufacturer 1. Preparation of Electrode Paste It is mainly used to mix electrode active materials, binders, solvents, etc., and stir evenly to form a slurry. 2. Coating The slurry prepared in the first step is uniformly coated on a collector (alum

Future development of lithium titanate battery technology It is necessary to comprehensively summarize the advantages and disadvantages of lithium titanate as a lithium anode material, including ultra-high safety, ultra-long life, high and low temperature work planning, high power, low cost, and green environmental protection. Disadvantages: low energy density of lithium titanate data, strong water absorption, high requirements for the battery manufacturing environment, the production process needs to be updated

Li-ion battery maintenance circuit: The charge and discharge maintenance circuit of two lithium-ion batteries consists of two FETs and a special maintenance integrated block S8232. The overcharge control tube FET2 and the overdischarge control tube FET1 are connected in series, and the battery voltage is monitored by the maintenance IC. When the battery voltage rises to 4.2v, the overcharge maintenance tube FET1 stops charging. In order to prevent misoperation, a delay capacitor is usually added to the external
