What is the black technology of "honeycomb battery", the representative of new energy vehicle power lithium battery? Lithium battery as the most core three electric components of new energy vehicles, directly related to the vehicle range, power, safety and other important performance. The first release of cellular battery technology has attracted the attention of many industry insiders and new energy users. Honeycomb battery" is what black technology? This article and I will find out!
What is the "honeycomb battery" black technology?
In recent times, the new energy vehicle power lithium battery industry news, on the one hand, the strong release of the "blade battery", on the one hand, the new announcement of the "sandwich" structure battery pack, and on the other hand, the "honeycomb battery The strong debut of "Honeycomb Battery" makes the power lithium battery instantly become the focus of many people's attention.
Honeycomb battery is the latest achievement developed by JAC New Energy after 14 years of research and development, with safety, all-weather availability and higher energy as its distinctive features. JAC new energy vehicles equipped with cellular batteries meet the safety standards of vehicle regulations, which can completely eliminate users' safety concerns. The cellular battery is a small energy cell selected during the cell selection, even if a single cell has thermal runaway, the lithium battery pack and the whole car will not catch fire.
Honeycomb battery is another new concept of lithium battery structure other than Ningde Time's CTP technology, BYD's "blade battery" and "sandwich" structure battery pack. The first report of "honeycomb battery" appeared in March 2020, is a power lithium battery developed specifically for new energy vehicles, compared to the general power lithium battery, "honeycomb battery" fully draws on the bionic design of honeycomb structure, to Compared with the general lithium battery, the "honeycomb battery" fully draws on the bionic design of honeycomb structure, and is unitized and packaged with the UE technology of epitaxial cladding, and all the cells in the lithium battery pack are 360° clad with lightweight self-leveling thermal conductive adhesive to create a safe and comfortable home for each cell.
The cells of the cellular battery are arranged in hexagonal shape and filled with thermal conductive adhesive between the cells, which ensures the heat dissipation speed of the cells. The 100% contact between the heat-conducting adhesive and the cell will accelerate the heat dissipation of the cell. The electrochemical reaction of the cells inevitably brings heat dissipation, and the thermal adhesive quickly transfers the heat out to ensure that the temperature difference inside the battery pack is ≤3°C.
The cellular battery is filled with thermal adhesive between the cells, thus achieving electrical and thermal isolation between the lithium battery cells. If one cell fails, it will not spread to the surrounding area and therefore will not cause a chain reaction.
The cellular battery is an NCA cylindrical lithium battery provided by Lixin Battery, which is also the supplier of the Tesla Model 3 and Mercedes AMG hybrid models. Unlike other models, the iC5 does not choose a soft pack, square battery, but a cylindrical lithium battery, making the design of the battery pack require a more rigorous process.
The cellular battery design allows for small cell size and flexible module structure, which can make full use of the irregular space of the battery pack to obtain maximum pack energy.
Compared to the "blade battery", "honeycomb battery" should not be underestimated, the new concept of lithium battery structure, so that the energy density of the power battery has increased significantly, the range has also increased by nearly 30% year-on-year, as a representative of lithium iron phosphate batteries, "blade battery" and "honeycomb battery" for lithium iron phosphate reverse has a very important impact.
