21700 Battery Higher Energy Density Less Cost

When the volume of monomer is raised, the number of parts needed for PACK will be reduced in proportion, thus driving down the cost of PACK. From 18650 to 21700 after the type switching type, single cell battery capacity can reach 3~4.8Ah, significantly improved 35%, the required number of battery equivalent energy can be reduced by about 1/3, Tesla Models electric car uses 7104 18650 batteries into the battery in parallel, the new Models 3, by 21700, the number of batteries will significantly reduced. The system will also reduce the difficulty of management and reduce the proportion of metal structure of battery pack and the electrical connector parts number, Tesla Pack the cost of the total system cost about 24%, is expected to decline the cost of the battery pack is considerable.
