Germany aims to boost safety of lithium-ion batteries
Lithium-ion batteries (pictured) are seen as the key to success for electric vehicles thanks to their extended range and power capabilities: however, their safety has been called into question on the back of several electric car fires.
Now, the German Federal Ministry of Education and Research (BMBF) is aiming to address this by launching a new public-private research project.
The project, which will last for three years, aims to improve the safety of the batteries for both electric and hybrid vehicles with the BMBF contributing €19million to an overall €36million project.
The focus of the research will be on new materials, testing methods and semi-conductor sensors.
The project is known as SafeBatt – in which partners will look at cell chemistry, particularly relating to the cathode material and electrolytes and how it can be optimised to improve the safety of lithium-ion battery cells.
There will be additional research into new semi-conductor sensors that are made of material never used in this area before – including graphene; while another element of the project will focus on a “Digital Battery Passport” that assesses and stores data on safety related issues, even during extreme weather conditions.
In addition, the SafeBatt team is hopeful of creating new safety models for battery cells which can help establish the correct operating status of the battery even during the most extreme conditions; and standardising a test procedure for product approval of lithium-ion batteries.
The SafeBatt project will run until June 30, 2015.
