TL;DR: In this paper, the effects of bromine doping on the structures and electrochemical properties of Li4Ti5O12 are extensively studied, and it is found that Br atoms can enter the lattice structure and enlarge the lattices parameters of Li 4Ti 5O12.

TL;DR: In this article, the cross-section view of a graphite-based cathode was observed upon cycles in a dual ion battery and it was shown that the cathode initially presented a huge irreversible thickness change (60%), and such thickness variation was prone to reduce and remain.

TL;DR: In this article, high-porosity porous graphene aerogels with excellent flexibility were fabricated via simultaneous reduction and assembly of graphene oxides in various alcohols, and the resultant supercapacitors exhibited effective specific capacitance up to 287 F g −1 (at current density of 0.1 A g − 1 ) with excellent cycle stability (>91% capacitance retention upon 8000 cycles).

TL;DR: Li et al. as mentioned in this paper developed a new in-situ measurement setup to visualize the two-dimensional internal temperature field distribution of the internal cross-section in the cylindrical cells, which opens a novel platform for acquiring solid evidence in studying the mechanism of thermal behaviors and designing safe Li-ion batteries.

TL;DR: In this article, the authors focus on the recent work with topics in the electrochemomechanical couplings of deformation and fracture of conventional and alloying electrodes through experimental characterization, theoretical and computational models.
