At the recently held 2024 Shenzhen eVTOL Expo, BAK Battery unveiled its latest advancements in lithium battery technology. Recognizing the demanding power requirements of electric vertical takeoff and landing (eVTOL) aircraft, BAK has invested heavily in research and development to present two key solutions: tabless large cylindrical batteries and semi-solid-state batteries.
BAK Battery’s tabless design for their large cylindrical batteries is a game-changer in the industry. By reducing internal resistance, this innovation not only relieves the load on thermal management systems but also delivers high-rate continuous discharge and charge capabilities, perfectly suited for the power needs of eVTOL products. In addition, BAK has made significant progress in developing semi-solid-state batteries with exceptional energy densities. The current energy density is an impressive 320Wh/kg, with aspirations of achieving even higher ratings in the future. The ultimate goal is to transition to all-solid-state batteries, which will not only meet the performance requirements of eVTOL aircraft but also revolutionize the low-altitude economy.
During the exhibition, BAK Battery showcased a range of large cylindrical battery products based on their tabless cell platform. The INR2170-48B and INR2170-55B cells stood out for their high-capacity and high-power performance, with a maximum continuous discharge rate of 8C and a cycle life exceeding 1,500 cycles. With an energy density of nearly 300Wh/kg, the INR2170-55B cell is particularly well-suited for lightweight, fully electric eVTOL applications. BAK Battery also introduced three semi-solid-state battery products, targeting the eVTOL, electric motorcycle, and electric vehicle markets, with impressive charge/discharge rates and capacities.
Dr. Guo Xinlu, Cylindrical Product Manager at BAK Battery, emphasized the company’s commitment to technological advancements and meeting future market demands. By continuously innovating in structural design and material systems, prioritizing R&D and commercialization, and anticipating market trends, BAK Battery aims to lead the way in next-generation battery technologies.
BAK Battery’s presence at the Shenzhen eVTOL Expo undoubtedly solidified its position as a frontrunner in the lithium battery industry, offering cutting-edge solutions to power the future of electric transportation.

Definitions:
1. eVTOL: Electric vertical takeoff and landing. Refers to aircraft that can take off and land vertically using electric propulsion.
2. Internal resistance: The opposition to the flow of electric current within a battery, which can lead to energy loss and reduced efficiency.
3. Energy density: A measure of the amount of energy that can be stored in a given mass or volume of a battery. Expressed in Wh/kg (watt-hours per kilogram), it indicates the battery’s capacity to store and deliver energy.
4. Cycle life: The number of charge and discharge cycles a battery can undergo before its performance significantly degrades.
