A moment with Kristina Edström,
Coordinator of BATTERY 2030+

Thank you for supporting the BATTERY 2030+ initiative and being a part of our battery community!

As usual, a lot of things have happened since the last newsletter. Our projects are working hard and preparing for the upcoming deliverables this fall. A short update will follow in this Newsletter from each project. We had two fantastic workshops in the last few months, one arranged by Bat4Ever and Spartacus the other by BIG-MAP and Hidden. We are proud of how engaging, hardworking and the amount of knowledge and competence all projects are contributing to the initiative.

BATTERY 2030+ has partaken in many digital activities this spring. We co-hosted a virtual round table together with Recharge discussing the new battery regulations during EU Green week. If you missed it you can watch it here. We partook in the Clean Batteries seminar by the Greens/EFA in May and the Virtual Conference on Advanced Materials by EU Portugal in June. Elixabete Ayerbe represented us at the Defacto workshop, A Digital approach in battery development, and Silvia Bodoardo represented us at Batteries Europes workshop for Skills and education for the emerging battery economy: European challenges and solutions. Well done!

In this Newsletter we present a short article about the Hidden project, we hope you enjoy it. In our next issue of the newsletter we will be focusing on Sensibat. We have also made some short informative videos about our project that you can find here.

Going forward we are planning our annual meeting on October 7th and Battery Innovation days starting November 22, please mark your calendars you are all very welcome. We also have an Excellence seminar series planned for the fall, more information on that will follow soon. We are also a partner for the Green Batteries Conference this October, you will find the link to sign up at the end of the newsletter.


A short update from our projects



July 2021 is the 11th month of the SENSIBAT project and what exciting months they have been! In this short timespan the project has already delivered ten reports and achieved two milestones. All SENSIBAT project reports are public and available on the project website so check out the results section if you want to know more.

The latest SENSIBAT activities include important steps in the development of an in-operando sensor to obtain data on the cathode and anode of the battery including the first EIS-tests as well as in the development of the internal pressure and temperature sensors. Tests for sensor cable feed-through show positive results. In addition, the baseline cells that will be used to analyse the impact of the implementation of the sensors have been developed and tests with these have been started.

We look forward to sharing more exciting results in the months to come so stay tuned!

The Hidden project is on schedule, results and reports are being disseminated accordingly on our website. On June 1st a workshop between BIG-MAP and HIDDEN took place and because of the great success another workshop between the two projects is in the works.

Regarding the plans for the fall, they will start focusing on exploitation routes for the key exploitable results of the project. Key exploitable results will be identified, result owners will be assigned and the start of discussing possible exploitation and commercialisation routes. The aim is to include draft exploitation plans for each result in Deliverable 7.2 (due in February 2022).

Keep your eyes out for Hidden's next newsletter coming out in October. Our month 12 project meeting will also be held around that same time.

Spartacus are preparing their upcoming deliverables that are due at the end of August. Among others the plans for exploitation and dissemination are carefully prepared.

Our social media activity plan has been approved by the consortium and we will continue to introduce the different workpackages via LinkedIn, focusing the work package leaders and their teams.

The public deliverables will be published also on the SPARTACUS website. In the next weeks we will prepare the dissemination on our website and communicate the available deliverables via social media.

The SPARTACUS project is also focusing on peparing the Green Batteries Conference series starting October and will take place every Tuesday afternoon from 1 p.m. to 5 p.m. Abstracts are being collected and reviewed for the different topics during the summer. Registration link will follow at the end of this newsletter.

The INSTABAT website is online! Please visit it

Development and testing of sensors have started (optical sensors, CO2 sensors, and reference electrodes) and we have first results on optical characterization for temperature measurements.

First cells prototypes have been prepared and tested. Definition of ageing protocols regarding to the objectives of the project (extrem conditions) are set up.

Concerning electrochemical models, this past months efforts have been oriented towards the development of a first working version of a finite-volume discretized implementation of a Newman model of intercalation Li-ion battery cell, compatible with the proposed estimator (i.e. state observer) design. The modularity of this code allows for the inclusion of new phenomena w.r.t. the state of the art, such as heterogeneous lithiation and temperature-dependent transport and reactions. It will ultimately be fine-tuned for the precise chemistry of the INSTABAT project.

The BIG-MAP project has been busy the last few months. All the BIG-MAP publications and deliverables are posted on the website.

On Twitter all the tweets presenting each BIG-MAP partner are being finalized and a new series of tweets to present each work package within the project is about to start. The publications and project deliverables posted on the website will also be disseminated via Twitter.

A successful Internal training event on the use of the developed online laboratory notebook took place in May.

A video has been posted on youtube and disseminated also via Twitter showing the new gloveboxes being installed at KIT (H. Stein lab). Watch it here...

Otherwise, a new web design and an animation video are on course and scheduled to be ready by fall.

The HIDDEN agenda -

High energy density battery with self-healing properties

A self-healing battery is a new star on the battery research sky. The idea is to slow down the aging process in the battery substantially. This is being done by hindering dendrite growth at the anode of the battery and has the potential to increase the lifetime and energy density of Li-metal batteries by 50 percent compared to today’s Li-ion batteries. This is what Hidden, one of the research projects within Battery 2030+, aims for.

Today’s most common electric vehicle (EV) batteries use graphite as the anode material. The main problem in the graphite anode is its limited energy density, which also eventually hinders the driving range of EV’s. The ideal anode material option for enabling high energy density batteries is metallic lithium. Unfortunately, the formation of dendrite growth, a form of “plaque” at the electrode surface, is an essential factor that limits the use of metallic lithium as the anode. Solid-State electrolytes (SSEs) could help controlling the nucleation and prevent the growth of dendrites, but it has proven to be difficult to develop and process SSEs combining high enough conductivity, mechanical properties, and stabilized, electrochemically active interphases with electrodes.

To get hold of the dendrite nucleation and growth, one needs to know more fundamentally what is happening in the battery and find solutions to prevent unwanted reactions at cell level. To do this, several things need to be in place; one is to use non-invasive analyzing tools to detect dendrites and applying multiscale modelling to accelerate the discovery of next generation electrolytes for alkali-metal anode-based batteries.

We aim to develop just that, and in combination with advanced algorithms, we can monitor the dendrites in the lab, model the growth virtually, and trigger the self-healing when needed, says Dr. Marja Vilkman, project leader for Hidden. We are looking at chemistry-neutral thermotropic ionic liquid crystals (TILCs)-based self-healing electrolytes. Their structure will be simultaneously i) encoded according to their tailor-made molecular design and ii) changed with the temperature; thus breaking the formed dendrites mechanically during phase transitions and upon heating above their clearing point. This dynamic process is fully reversible with the temperature. When complemented by a polarized piezoelectric polymeric separator, that creates an electric field when bended, the dendrite formation will diminish. If TILCs are topped up with protective additives to generate self-healing electrolytes, dendrite nucleation and growth will be ultimately put under smart control to make batteries with enhanced energy density and improved lifetime.

Another important part of the Hidden project is to make sure that the materials and their processes are scalable and industrially fit for manufacturing. Europe has set forth to be the first carbon free continent by 2050. Hidden contributes by enabling sustainable energy storage with longer battery lifetime and higher energy storage capacity.


Have a fantastic summer!

From all of us at the coordinating project BATTERY 2030 PLUS. We want to wish you a fantastic summer full of sun, laughter and relaxation. Get energized for the fall wich will be packed with lots of great collaborations, events and battery innovations.
