Lithium-ion battery with silicon anode, nickel-rich cathode and in-cell sensor for electric vehicles
Lithium-ion batteries are the energy source of the future. Autonomy and rapid recharging are essential features to promote the adoption of electric vehicles. The EU-funded SeNSE project aims to create next-generation lithium-ion batteries with a silicon-graphite composite anode and a nickel-rich NMC cathode capable of achieving a volumetric energy density of 750 Wh/l. This new generation of batteries will also feature a sensor-based charge management system directly integrated into the cells to enable faster charging, improved durability and recyclability, and lower production costs.

High energy lithium sulphur cells and batteries
ALISE (Advance Lithium Sulphur Batteries for Hybrid Electric Vehicle) focuses on the development and transition to commercial production and on understanding the electrochemical processes involved in lithium-sulphur batteries.
2015 / 2019 – Reference: H2020-NMP-GV-2014 – project n°666157
It aims to develop an innovative battery technology capable of meeting the needs of the European automotive industry in line with the European materials roadmap. The project aims to design batteries capable of reaching 500Wh/Kg in stable LiS cells.
It includes activities dedicated to durability, testing and life-cycle analysis that will ensure the safety and adequate cyclability of the batteries developed at a cost that should remain competitive. Initial materials research will be intensified during the course of the project, so that pilot-scale quantities of materials will be introduced into the new cell architectures, contributing to the advancement of the state of the art.
The project’s approach will enable real breakthroughs to be made in terms of components, cell integration and associated architecture. New materials will be developed and optimised for the anode, cathode, electrolyte and separator. Complete panels of specific tools and associated modelling will be developed from the single cell to the battery pack. Activities will focus on the development of new materials and processes at TRL4 level.
The lithium-sulphur technology will be demonstrated up to battery level, with on-board validation. Validation of the prototype (17kWh) with its corresponding range (100km) will take place on track. ALISE is more than a linear bottom-up approach from materials to the cell. This project aims to lay the foundations of solid resources for obtaining stable unit cells, with an additional top-down approach from the final application to the optimisation of the unit cell.
Si-Drive
Silicon alloying anodes for high energy density batteries comprising lithium rich cathodes and safe ionic liquid-based electrolytes for enhanced high voltage performance.
Si-DRIVE is focusing on developing the next generation of Li-ion batteries based on an ionic liquid-based solid electrolyte, a silicon anode and a cobalt-free cathode.
Si-DRIVE will develop the next generation of rechargeable Li-ion batteries, enabling mass-market electric vehicles at a competitive cost thanks to processed materials and cell chemistry innovations, offering enhanced safety with superior energy density, life and fast charge capability, using sustainable and recyclable components. The technology encompasses amorphous silicon coated with a conductive copper silicide network as the anode with polymer/ionic liquid electrolytes and lithium-rich (cobalt-free) high-voltage cathodes via evolutionary processes, which can be manufactured in Europe. The components have been taken to TRL3 (Technology Readiness Level) through a preliminary lab-scale analysis, with a strategy of component improvement to achieve a prototype demonstration (TRL5) by the end of Si-DRIVE.
In-depth theoretical and experimental studies will probe and control the interfacial processes that have so far limited Li-ion technologies to marginal gains, looking at materials design and eliminating capacity-weakening mechanisms.
Si-DRIVE technology will exceed the stringent requirements of electric vehicle batteries, where safety is paramount, by dramatically improving each component of the Li-ion platform in a competitive, market-driven process over the entire life of the battery. The technology will also need to prove its suitability for reduced energy density second life applications beyond the main life of electric vehicles, prior to cost-effective recycling of materials in line with the circular economy.
The Si-DRIVE consortium has the expertise required from both academic and industrial partners to implement this technology. It will cover materials design and synthesis, electrochemical testing, prototyping and validation of production methods, life cycle assessment and development of recycling processes.

POLYSTORAGE
Training programme in new-generation polymers for energy storage
The POLYSTORAGE ETN project aims to design high-quality training courses in the field of “New-generation polymers used for electrochemical energy storage”.
The aim of this project is to train materials scientists capable of meeting Europe’s future energy and environmental challenges. The balanced combination of fundamental materials and polymer science with applied research in advanced energy storage devices is the keystone of this training network. A comprehensive training programme has been designed on two levels: local activities such as enrolment in PhD programmes, courses… and network-wide activities such as sectoral secondments, 6 workshops, 2 schools and a final conference.
The aim is to exploit the large number of potential synergies between innovative polymers and next-generation energy storage technologies, such as post-lithium batteries, redox flow batteries and all-polymer batteries. Industrial participants will be actively involved in training activities and in exploiting the results of the project. Solvionic is a partner organisation in the project.

High energy lithium sulphur cells and batteries
“HELIS (High energy lithium sulphur cells and batteries) focuses on the development Lithium-Sulphur cells. They will be tested according to automotive specifications.”
Thanks to their high theoretical energy density and cost-effectiveness, lithium-sulfur batteries (LSBs) are viable candidates for commercialization among all post-Li-ion battery technologies. But despite our best efforts, there are still problems to be solved… Some technological aspects, such as the development of host matrices, the interactions of the host matrix with polysulfides and the interactions between sulfur and electrolyte, have been successfully developed as part of the Eurolis project. The open porosity of the cathode, the interactions between host matrices and polysulfides, and the appropriate solvation of polysulfides all proved important for the full utilization of sulfur.We have also shown that effective electrode separation enables stable cycling with excellent coulombic efficiency. The remaining questions are mainly related to the stability of the lithium anode during cycling, the engineering of the complete cell and issues concerning the implementation of LSB cells in commercial products (ageing, safety, recycling, batteries). The instability of lithium metal in most conventional electrolytes and the formation of dendrites due to the uneven distribution of lithium during deposition are at the root of several safety problems, directly attributable to dendrites and low coulombic efficiency due to a constant increase in internal resistance linked to electrolyte degradation. Stabilizing the lithium metal and the interface layer will therefore have a major impact.
