Bitauto News On August 28, China Innovation launched the first OS lithium iron manganese battery in the aviation industry. The battery uses this thermoelectric separation technology and has an energy density of 180 Wh/. kg. Support the whole vehicle to reach 700 kilometers.
OS' battery platform technology was showcased at the World New Energy Vehicle Conference in Hainan last year. It has completed pilot testing and is currently undergoing reliability testing on compatible models. OS batteries use the first principle of performance to reconstruct cell structure and manufacturing technology. It is the fourth form of packaging after cylindrical, packaged in soft and square form. It has higher energy density, higher manufacturing efficiency and higher space utilization.
The beatOS lithium manganese battery has the following features: First, better safety is a thermoelectric separation technology that ensures robust system safety. Secondly, the amount of precious metals used is significantly reduced, including the amount of nickel, cobalt and lithium, which allows users to obtain lower purchase costs under the same mileage conditions. Third, the height of the battery is reduced by 7% and the ground clearance is higher, reducing the likelihood of collision. Fourth, the energy density of the phosphate battery reached 180 Wh/kg, and the energy density retention rate exceeded 80%; fifth, it allows the vehicle to reach 700 kilometers; Sixth, it can be repaired and dismantled. Seventh, in terms of energy replenishment experience, we are rechargeable and replaceable.
TPP (Thermal Suppression Protection) 2.0 technology developed by China Innovation Aviation adopts the design of thermal and electrical separation when the battery encounters thermal runaway and pressure discharge, high temperature and. conductivity will quickly cause more complex short circuits. The decompression direction of the battery core is in the height direction – Z direction. This will not have a direct impact on high current connections, including short circuits caused by insulation damage and the deposition of conductive substances at high temperatures. At the same time, an independent decompression space is also set up to ensure that the gas is not cross-linked with strong electricity. In addition, saving space in the Z direction, the collision space and decompression space of the original battery cells are combined into one, saving about 7% ofspace at height.
Thanks to technological innovation at the PACK level, the development of the phosphate system mileage is supported at 700 kilometers, thereby reducing the cost of the initial period between 600 kilometers and 800 kilometers. the slope of the curve becomes smaller. Lithium iron manganese phosphate can replace the original ternary product on models with a mileage of 700 kilometers.
Through the radial gradient design of the manganese element, a good lithium interface is constructed, including the design of a “zero” active superconducting electrical interface. Thanks to the influence of manganese, our lifespan has been greatly improved compared to the past and can reach 2,500 cycles.
If a dent occurs, it can be repaired. If the cold plate is damaged, the cold plate can be repaired if the battery core is damaged, the module can be replaced ; instead of replacing the entire package. High after-sales repair costs.

1. The metal surface of lithium batteries used for a long time will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone, and the use time of the lithium battery will be shortened. A rubber scraper or other cleaning tool can remove rusty materials on the surface and improve contact between the battery and the phone.
2. Low temperature can change the electrolyte inside the lithium battery and promote chemical reactions in the newly frozen battery. The process of using a baLithium battery is actually a process of charging and discharging.
3. When a lithium battery is placed in a low temperature environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interface, will undergo significant changes, resulting in inactivity temporary inside the battery and a reduction in leakage current. Therefore, after recharging, the battery life of the mobile phone will increase.
Detailed informationFirst of all, it is necessary to avoid charging the electric vehicle battery for a long time. The so-called “overcharge” is preferably a charging time of 8 to 10 hours; battery "overnight", which is extremely harmful at night. It is prone to fire accidents and will cause serious damage to the battery, so it is not recommended.
Second, vehiclesElectric vehicles must be recharged in time to avoid “power loss” of electric vehicles. Generally, if the car is not used, it should be charged once a month to ensure its normal usage cycle. Especially for lead-acid batteries, not charging for a long time will cause permanent damage to the battery.
In addition, charging electric vehicles requires a suitable environment (25 degrees, ventilated, cool and open place). Avoid placing them in high temperature environments or charging indoors. Many fire accidents are caused by illegal charging. The charging environment is therefore also crucial.
