Square cell: The king of energy density and integration

main content

Material innovation

The square battery cell adopts an aluminum alloy shell (with a thickness of 0.8-1.2mm), and the internal electrode sheets are made by lamination process. The filling rate of active substances is as high as 98%, and the energy density exceeds 250Wh/kg. Under the lithium iron phosphate (LiFePO₄) system, the cycle life exceeds 3,000 times and the capacity retention rate is over 80%.

Structural breakthrough

Blade design: BYD's patented technology extends the battery cell length to 960mm and the thickness to only 13.5mm. Through array arrangement, the battery pack is modularized, increasing the volume utilization rate by 50%.
Bipolar TAB layout: The positive and negative tabs are symmetrically distributed to reduce the internal resistance to 8mΩ, supporting continuous discharge up to 5C, meeting the frequent start-up requirements of motorcycles.

Safety protection

Intelligent control of pressure relief valve: The top of the shell is integrated with a memory alloy pressure relief valve, which automatically opens when the pressure reaches 1.5MPa, and the leakage of electrolyte is less than 0.1mL.
Ceramic-coated diaphragm: The temperature resistance of the aluminum-coated diaphragm is enhanced to 180℃, and the thermal spread rate in the needle-puncture test is reduced by 60%.

START-STOP LITHIUM battery

Enov start-stop battery is designed to provide excellent performance for high-demand start-stop vaehicles. It adopts the third-generation intelligent lithium platform architecture to achieve technological breakthroughs in core indicators such as cycle life, environmental adaptability and energy density. Compared with the traditional lead-acid battery system, the energy efficiency is increased by 210%, the cycle life is extended by 8-10 times, and the monthly self-discharge rate is controlled within 3%. Enov's unique low-temperature battery technology makes a breakthrough in achieving stable output in the whole climate domain from -30℃ to 65℃, maintaining more than 90% of the effective capacity release under extremely cold conditions (-30℃), and maintaining 90% of the capacity in high temperature environments (65℃).
The start-stop battery series products cover the mainstream voltage platform of 12V/24V/48V, and support flexible configuration of LFP (lithium iron phosphate) and NCM (lithium nickel cobalt manganese oxide) dual-material system. All models adopt modular design to support customization of different model specifications.
