CALB to Launch New Battery With Longer Cruising Range
On August 27, Liu Jingyu, the chairman of China Aviation Lithium Battery (CALB), delivered a video speech at the 2022 World New Energy Vehicle Congress, saying that the company will soon launch a 350Wh/kg multi-element battery with lithium ferromanganese phosphate to meet 4C fast charging, and a 400Wh/kg semi-solid battery, an all-solid battery, lithium sulfur batteries and others.
CATL, China’s leading battery firm, has led the development of the industry, and announced on August 27 that its Kirin battery supporting 1,000 km battery life will be applied on vehicles in the first quarter of next year.
As one of the second-line battery enterprises to rise in recent years, CALB, which has several patent disputes with CATL, is accelerating its catch-up efforts. Established in 2015, CALB has established several industrial bases. During China’s “14th Five-Year Plan” period, the planned production capacity of the company exceeded 500GWh, and overseas markets will also be explored.
In terms of high-voltage and ternary battery technology, CALB has taken the lead in adopting high-voltage 5-series products to achieve 600 km in battery life. Liu Jingyu said that the 6 series high-voltage products to be launched by CALB can reach the level of 300Wh/kg, supporting a battery life of more than 1,000 km.
Liu believes that the density of high-voltage battery products can reach 320Wh/kg in the next few years, covering the endurance requirements of most high-performance vehicles. High-voltage technology not only greatly improves energy density and safety, but also realizes the high utilization rate of lithium and nickel resources. Moreover, the company is trying to use more magnesium in its batteries, thereby reducing dependence on nickel.

Liu said, “In the past few years, the cobalt content of ternary batteries has been reduced by 50%. In the future, through the innovation of materials and battery technology, it is expected that the cobalt content will be reduced to a very low level. At the same time, the promotion and application of batteries such as ferrous lithium phosphate, lithium manganate will be continuously expanded, greatly reducing the dependence on cobalt resources.”
