GMG's Graphene Aluminium-Ion Battery Update: Minimal Temperature Rise Identified While Fast Charging
GMG's Graphene Aluminium-Ion Battery Update: Minimal Temperature Rise Identified While Fast Charging
Brisbane, Queensland, Australia--(Newsfile Corp. - February 14, 2024) - Graphene Manufacturing Group Ltd. (TSXV: GMG) ("GMG" or the "Company") provides the latest progress update on its Graphene Aluminium-Ion Battery technology ("G+AI Battery") being developed by GMG and the University of Queensland ("UQ").
澳大利亞昆士蘭州布里斯班--(Newsfile Corp.,2024 年 2 月 14 日)-石墨烯製造集團有限公司(TSXV:GMG)(”GMG“或者”公司“)提供了其石墨烯鋁離子電池技術的最新進展(”G+AI 電池“) 由 GMG 和昆士蘭大學開發 (”UQ“)。
The Company is pleased to announce that it has identified minimal temperature rise when charging and discharging GMG's Graphene Aluminium-Ion Battery. This is observed when charging and discharging multiple times at high C- rates (C rate measures the current in a which a battery can be charged or discharged, eg. 1 C rate the battery should be able to be fully discharged in 1 hour). As shown in Figure 1, the temperature of a high-quality lithium-ion battery, produced by a world leading brand, can exceed 60 degrees Celsius when being discharged at the maximum current allowed (4.8 C-rate - an estimated 0.8 A/g on the cathode active material mass). By comparison, GMG's Graphene Aluminium-Ion Battery temperature is 29 degrees Celsius when it is discharged at even higher current density (20 C-rate - approximately 2.0 A/g on the cathode active mass). The temperatures of both batteries were taken with the room temperature at 23.5 degrees Celsius (+/- 0.5 degrees Celsius).
該公司很高興地宣佈,它已確定對GMG的石墨烯鋁離子電池進行充電和放電時的溫度升高最小。當以高 C 速率多次充電和放電時,就會出現這種情況(C 速率衡量的是電池可以充電或放電的電流,例如,在 1 C 的速率下,電池應該能夠在 1 小時內完全放電)。如圖 1 所示,由世界領先品牌生產的高質量鋰離子電池,在允許的最大電流(4.8 C 速率——估計陰極活性物質質量爲 0.8 A/g)下放電時,其溫度可能超過 60 攝氏度。相比之下,GMG的石墨烯鋁離子電池以更高的電流密度(20 C速率——在陰極活性質量上約爲2.0 A/g)放電時,其溫度爲29攝氏度。兩塊電池的溫度都是在室溫爲23.5攝氏度(+/-0.5攝氏度)的情況下測量的。

The Company intends to validate with further testing the possibility that its battery may not need thermal management, even at high charge and discharge rates. This creates the potential for significant cost reduction at the system level and highly reduced system cost.
該公司打算通過進一步測試來驗證其電池即使在高充放電速率下也可能不需要熱管理的可能性。這爲在系統層面顯著降低成本和大幅降低系統成本創造了潛力。
- GMG's Graphene Aluminium-Ion Battery may not need a thermal management system when used in an electric vehicle battery pack or an energy storage system, which will lead to a simpler, more cost effective and higher energy density battery pack. Most Lithium-Ion Battery Packs require a thermal management system, such as the one shown in Figure 2 below.
-GMG的石墨烯鋁離子電池在電動汽車電池組或儲能系統中使用時可能不需要熱管理系統,這將導致更簡單、更具成本效益和更高的能量密度的電池組。大多數鋰離子電池組需要熱管理系統,例如下圖 2 所示的系統。
- The elimination of thermal management can potentially reduce the weight of an electric vehicle battery pack by up to 16%. For example, the thermal management system of a Lithium-Ion Battery Pack can weigh up to 80 kg out of a total of 480 kg. Such a weight reduction achieved through the elimination of thermal management translates into more energy volumetrically (approximately 10%), as well as vehicle mass reduction for more range. Additional range improvements could be expected to come from no thermal management parasitic drain on the battery during operation.
-取消熱管理有可能使電動汽車電池組的重量減少多達16%。例如,鋰離子電池組的熱管理系統的總重量可達 480 kg,而總重量可達 80 kg。通過消除熱管理實現的這種重量減輕可以轉化爲體積上的更多能量(約10%),以及車輛質量的減輕,以獲得更大的續航里程。由於電池在運行過程中不會出現熱管理寄生消耗,預計還會有進一步的續航里程改善。
- Furthermore, because GMG's Graphene Aluminium-Ion Battery has no combustible volatile organic materials, it is more resilient to the risk of chemical fires, such as those that have occurred with Lithium-Ion Batteries.
-此外,由於GMG的石墨烯鋁離子電池不含可燃的揮發性有機物質,因此它更能抵禦化學火災的風險,例如鋰離子電池發生的化學火災。
Battery Technology Readiness Level
電池技術就緒級別
The battery technology readiness level ("BTRL") of the Graphene Aluminium-Ion technology remains at Level 4 (see Figure 4). GMG is currently optimizing electrochemical behaviour for pouch cells via ongoing laboratory experimentation. When GMG commissions its Pilot Plant, it is anticipated that the Company's battery technology will progress to BTRL 7 and 8 since the equipment and process to make the Graphene Aluminium-Ion batteries are the same as those used to make Lithium Ion Batteries.
石墨烯鋁離子技術的電池技術就緒級別(“BTRL”)保持在4級(見圖4)。GMG目前正在通過正在進行的實驗室實驗來優化袋裝電池的電化學行爲。當GMG投入試點工廠時,預計該公司的電池技術將發展到BTRL 7和8,因爲製造石墨烯鋁離子電池的設備和工藝與用於製造鋰離子電池的設備和工藝相同。
