Summary: This paper proposes a dissipative cell equalization algorithm based on charging electric quantity estimation for hybrid battery packs, aiming to stabilize the energy output of the pack. The effectiveness of the algorithm is demonstrated through simulations and the relationship between cells in the pack is analyzed. Results show that the dissipative equalization strategy can achieve closely matched theoretical values after approximately 15 to 20 standard cycles, with a relative difference of no more than 1% and minimal fluctuations. Therefore, this equalization method can change and recover the electric quantity difference, achieving energy stabilization for hybrid battery packs.

Summary: This study demonstrates that two endogenous oxygen pathways involved in strong exothermic reactions lead to uncontrollable states in the NMC811|graphite pouch cell, with significant safety concerns. Approximately 41% of thermal-induced oxygen reacts aggressively with ethylene carbonate at the cathode/electrolyte interface, accelerating the self-heating rate and triggering thermal runaway. The residual oxygen that survives the reaction with carbonate spreads to the lithiated anode, generating major heat and bringing the battery to the maximum destructive temperature during thermal runaway.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
