Turbine Crew Co., Ltd. announced that it presented research conducted in collaboration with Professor Woongil Kang of Honam University and Dr. Seungbok Lee, formerly of Chonnam National University, at several prominent conferences, including the 2023 Korean Electrochemical Society Fall Meeting/Academic Conference, the 2023 Korean Institute of Chemical Engineers Fall Meeting/International Conference, and the 2023 Korean Industrial and Engineering Chemistry Fall Meeting/Academic Conference. The research was presented in the new renewable energy category.

The poster presentation, titled "High-performance Polymer Lithium Secondary Battery Based on Wind Power (ESS) with Improved Charging Capacity," focused on addressing the challenges in effectively utilizing renewable energy sources like wind and solar power. According to Turbine Crew, the study was prompted by the increasing volume of waste batteries, which are often complexly designed in series/parallel configurations at the module level, making repairs difficult when high-voltage battery modules fail. The research explored solutions for reusing and recycling necessary cells through balancing techniques, with a focus on lithium-polymer batteries collected from drones.

Based on the results of this study, Turbine Crew plans to apply the technology to areas without reliable power supply, such as remote island regions, smart farms, and smart cities. The company also confirmed through KETI (Korea Electronics Technology Institute) certification that the performance of the reused batteries is nearly equivalent to new ones, with plans to further narrow any performance gaps.

The research results highlighted that the system allows for precise monitoring of parameters like potential, voltage, current, and state of charge (SOC), and it can handle overvoltage/undervoltage and 100% overcharge conditions. The battery system also allows for repeated discharge current cutoffs and recoveries, and it operates effectively in temperature ranges from -18°C to -50°C and humidity levels from 10% to 80%.

A representative from Turbine Crew stated, "By integrating the technology presented in this study with public Wi-Fi, Internet of Things (IoT), and autonomous cooperative driving technologies, we can enhance public safety and convenience. We also aim to develop technology that reduces energy infrastructure costs by consolidating road facilities."

The representative further explained, "Unlike conventional smart poles, drone-based waste batteries require a high C-rate of 25-30, which means they demand higher current than traditional batteries. These high-performance batteries, balanced for new renewable energy, are easier to maintain and manage based on the installation area. They can serve as the primary energy output base for road facilities."

Additionally, the company emphasized that it has secured technology for waste battery system control (packaging) using lithium-polymer waste batteries, with commissioning data obtained to verify safety. Unlike traditional secondary batteries (lead-acid batteries), which cannot supply power if a cell fails, the batteries developed by Turbine Crew are designed to maintain power supply even if some cells fail, ensuring operational stability.

Turbine Crew has filed for patents and PCT applications for the technology presented in this study. The company is currently conducting POC (proof of concept) verification in front of the Jangseong Army Division in Jeonnam. Additionally, they are actively promoting their technology at various events, including the 2023 Gwangju Future Industry Expo, the 2023 Korea Smart Grid Expo, and NEXPO Tallinn in Northern Europe.
