Since the beginning of the year, Calix’s Advanced Batteries line of business has continued to progress development of its cathode active materials across multiple fronts. The lithium manganese oxide (LMO) cathode materials continue to be optimised, with the latest samples exhibiting a specific discharge capacity of ~130mAh/g, up from ~120 mAh/g previously, based on lab-scale samples and test results.
In January, Matt Boot-Handford (GM Research & Development and Deputy Chief Scientist) and Hinne Temminck Tuinstra (GM Strategy and Portfolio) made the journey to AMTE Power’s Manufacturing Plant in Thurso, at the northern tip of Scotland, UK to observe the latest pilot line pouch cell manufacturing trials with Calix’s LMO cathode active material. The AMTE team produced excellent quality foils which were subsequently assembled into 3.5Ah pouch cells and are now being evaluated. Later this month, AMTE will commence a production campaign to make commercial format pouch cells that will be assembled into a 2.4 kWh pack for powering an electric motorbike application.
In Australia, Deakin University’s Battery Research and Innovation Hub (BatTRI-Hub) has begun fabrication and testing of electrode foils manufactured in-house with Calix’s LMO cathode active materials. Results from tests at AMTE and BatTRI-Hub are expected in the next quarter. Previous tests on Calix’s LMO materials indicate excellent potential for high power applications, such as industrial vehicles and power tools.
