What is the best strategy for the mechanical reinforcement of soft SPEs in Lithium metal batteries?
Jannik published a Comparative Study of the Mechanical Reinforcement by Blending, Filling, and Block Copolymerization in Bottlebrush Polymer Electrolytes in ACS Appl. Polym. Mater. Both Filling and block copolymerization improves the reinforcement, but block copolymer approach has some additional advantages. https://doi.org/10.1021/acsapm.4c00161
Hyperbranched polyesters as solid polymer electrolytes in lithium metal batteries
A joint research work of Jannik Petry with Suhrit Ghosh, IACS, Kolkatta is published in European Polymer Journal. It deals with the feasibility study of novel polymer architectures as SPEs in all solid state Lithium metal batteries. https://doi.org/10.1016/j.eurpolymj.2024.112965
Design principles for acceptor copolymers - Poly(DPP-TPD)s
Joint research work with Chris McNeil (Monash University) on structure property relationship of a series of P(DPP-TPD) copolymers containing two different acceptor moieties published in Adv. Funct. mater. https://doi.org/10.1002/adfm.202314696. This is part of a joint PhD of Andreas Erhardt between Bayreuth and Monash.
Highly efficient acceptor-acceptor linkage strategy toward n-type OECTs
Congratulations to Andreas and Adrian for publishing their research work on highly efficient n-type OECTs involving acceptor-acceptor linkage strategy in Adv. Electron. Mater. 2023, 2300026; DOI: 10.1002/aelm.202300026. Two different acceptor moieties were so selected that there is negligible torsional angle between them leading to high planarity and excellent mixed ion-electron conduction properties.
Clickable Poly(glycidyl propargyl ether) platform for multifunctional SPEs in all solid state batteries
Congrats to Alexander on publication of the Clickable multifunctional SPEs for the application in all solid state Lithium Metal Batteries, published in Journal of Energy Storage, 2023 (https://doi.org/10.1016/j.est.2023.107348).
Versatile n-dopants and mechanism of n-doping using alkali carbonates elucidated
Congrats to Adrian and Andreas for the Adv. Funct. Mater. (https://doi.org/10.1002/adfm.202300614) paper on a new and facile route for n-doping of conjugated acceptor copolymers and for the detailed elucidation of doping mechanism. The doped system is successfully tested for thermoelectrics.

Tuning of composition and morphology of LiFePO4 cathode for applications in all solid-state lithium metal batteries
Harimohan published a detailed study of influence of composition, morphology and additives on performance of LiFePO4 cathode for applications in all solid-state lithium metal batteries in Scientific Reports, 12(1):5454, 2022. This is very useful for all groups working in all solid state batteries
High electron mobility and tuneable glass transition temperature in fullerene-functionalized polynorbornenes
Andreas published record bulk electron mobilities for fullerene-functionalized polynorbornenes with tuneable glass transition temperature and fullerene contents. The bulk charge carrier mobilities were determined in SCLC devices. DOI: 10.1039/D2TC00496H J. Mater. Chem. C, 2022, Advance Article
"BEYOND PEO" Solid polymer electrolytes from polyesters with diester sidechains for lithium metal batteries
Dominic, Alexander and Harimohan published together a new concept for matrix polymers based on polyesters to realize solid polymer electrolytes with high lithium transport number as well as good specific capacity retention in a wide range of T of 40-80°C and even at high C-rates in solvent-free all solid-state Lithium metal batteries.
