The camp of large cylindrical batteries is growing day by day

Unlike BYD's quietly researching and producing large cylindrical batteries, a large number of battery companies are joining the large cylindrical battery camp with great fanfare.

The domestic market has the deepest layout in the field of large cylindrical batteries, and the most aggressive enterprise to promote it is Yiwei Lithium Energy. Its capacity planning of large cylindrical batteries in 2025 will reach 200GWh, far higher than the capacity planning goal of 40GWh in the CATL.

Yiwei Lithium Energy has the bottom gas to expand the production of large cylindrical batteries. Its announcement on June 25 shows that the company's cylindrical Lithium iron phosphate battery has achieved a total of about 88GWh of customer intent demand in the next five years, and the ternary large cylindrical battery has achieved a total of about 392GWh of customer intent demand in the next five years.

On January 28, 2023, BIG, which was the first in China to launch the 4680 full pole ear large cylindrical battery, announced that it would invest 13 billion yuan in Changzhou and plan to build a 30GWh large cylindrical battery production line and an international research and development center. This is the first large cylindrical battery project in Changzhou.

In December 2022, Guoxuan High Tech demonstrated for the first time to overseas merchants the 39Ah and 50Ah 46 series cylindrical cells, with an energy density of 310Wh/KG. They can quickly charge up to 80% in 18 minutes at room temperature and ensure no thermal diffusion in the UN38.3 limit testing environment.

In October 2022, Yuanjing Power reached a strategic partnership with BMW Group, and Yuanjing Power will provide cylindrical batteries for BMW's new generation models starting from 2026.

Based on the One Stop minimalist design, China Innovation Airlines has launched a "top flow" large cylindrical battery, which reduces the internal resistance of the structure by 50% and can achieve an energy density of up to 300Wh/kg, achieving 6C+fast charging.

In addition, domestic manufacturers such as Ruipu Lanjun, Honeycomb Energy, Penghui Energy, and Zhongbi New Energy, as well as foreign companies such as Panasonic, LG New Energy, Samsung SDI, and Northvolt, are all laying out large cylindrical batteries.

summarize

Weike Network Lithium Battery has noticed that Tesla, BMW, General Motors, Volvo, Stellantis, Dongfeng Landu, JAC, Porsche, NIO, and others have publicly announced or considered using large cylindrical batteries.

Although BYD has a blade battery as a 'sharp weapon', it is clear that it does not 'put eggs in one basket'. Therefore, BYD is also laying out a large cylindrical battery that can meet both high energy density and low cost requirements.

In addition to the layout of large cylindrical batteries, BYD also has profound technology accumulation in Sodium-ion battery, Solid-state battery and other fields!
