Innovative 3D electro-printing method to improve power, capacity and safety of lithium ion-batteries
Emissions from transport currently represent a global environmental disaster, accounting for approximately 25% of Europe’s greenhouse gas emissions. Electric Vehicles (EVs) offer the most likely solution to reducing the environmental impact of transport in the EU. However, their full potential has not been achieved mainly because the performance of current EV battery technologies is simply not comparable with that of petrol/diesel engines. This is largely due to long charging times, insufficient battery capacity for long distance travel, maximum travel distances highly affected by the environmental conditions, limited life span and high cost for customized battery manufacturing.
A large amount of investment has been poured into the improvement of the chemistry of EV batteries to overcome these limitations. However, the major limitation can instead be found in the physical architecture of the battery. The 2D architecture of the lithium-ion battery (LiB) severely limits battery performance by restricting electron diffusion and reducing the speed and magnitude of energy delivered by the battery. It also imposes a high internal resistance, resulting in major performance limitations and enhanced degradation pathways within the battery. 2D batteries cannot be built thicker to increase capacity, and 2D batteries with large loads suffer from issues with heat dissipation. Until this fundamental issue with the battery architecture can be overcome, LiBs will not improve sufficiently to enable true electromobility.
Addionics have developed a paradigm-shifting 3D battery architecture that significantly improves battery performance regardless of the battery chemistry. The innovation centres on the ability to produce 3D electrode components (current collectors) through a proprietary 3D electro-printing process based on advanced, cost-effective electrodeposition techniques. This revolutionary approach is unique to Addionics and will disrupt the battery industry.
