CALB Introduces U-Shaped Battery Technology
A new so-called U-shaped battery from CALB is set to challenge CATL’s Qilin and Tesla’s 4680 batteries once it goes into production.CALB is a Chinese battery manufacturer that wants to compete with the much larger and well known. It has a long way to go. CATL has about a third of the global battery market. CALB has only a 3.7% market share, but thinks it has a tiger by the tail with its latest battery technology — the U-shaped battery.
While CALB has not released any details about the structure inside its new cells with the “U-structure,” it does say that they feature new chemistries and that electrical current “flow paths” have been reduced by 70%. That in turn has the effect of reducing the internal resistance of the cell by 50%, according to the company.
Xie added that treating the shell of a battery cell as a conductive component results in a relatively long path for the current to flow through. Most battery shells are made of steel, which is not a particularly good conductor of electricity. He also indicated the new cells from CALB are about 3% more space efficient.The pace of research and development in batteries is torrid these days, as the transition to electric transportation gains momentum.
