Battery platform

Published on 29 April 2016

FOR BETTER LITHIUM-ION BATTERIES OF ALL SIZES

The battery platform boasts all of the know-how and heavy equipment required to develop and produce small runs of lithium-ion batteries. R&D at the platform starts with identifying and synthesizing materials to optimize battery performance, and encompasses manufacturing the various components (such as battery electrodes and electrolytes), assembling the battery packs, and integrating them into complete systems. Battery safety and performance are assessed via a range of tests that include total destruction of the battery.

The platform has around 20 pieces of heavy equipment, including coating and filling machines and a test assembly line. The platform’s work focuses on lithium-ion batteries and battery packs of all sizes, from tiny hearing-aid batteries weighing in at just a few grams to 300-kg electric-bus batteries. The platform’s size and scope make it unique in Europe. With a strong commitment to industrial R&D partnerships, the platform works with around 30 manufacturers, including Renault, Prayon, Umicore, and Solvay (on battery materials).
