In order to tackle different challenges related to the conventional energy consumptions in the near future, people need to dig more into the different types of green new energies, and the use of lithium-ion battery plays a very important role. It is necessary to enhance the performance of lithium-ion batteries via the improvement of separators. Lithium-ion batteries are now widely used in the electrical vehicles industries for their high power, long life circle, small weight and volume, large operating temperature range, and no memory effects. Separators are one of the important components of lithium-ion batteries since they can isolate the electrodes and prevent electrical short-circuits. The separator is a key element in all lithium-ion battery systems since it allows the control over the movement of ions between the anode and the cathode during the charge and discharge processes. Nowadays, to meet the safety demands of batteries, thermo-tolerant separators have become increasingly important for battery design and performances. As a result, some potential developments of the separators such as the inorganic coating and heat-resisting polymer methods are explained in this article. At the same time, the developments of those methods will also be discussed.

Abstract As one of the significant enablers of portable devices and electric vehicles, lithium-ion batteries are drawing much attention for their high energy density and low self-discharging rate. A major hindrance to their further development has been the “range anxiety”, that fast-charging of Li-ion battery is not attainable without sacrificing battery life. In the past, much effort has been carried out to resolve such a problem by either improve the battery design or optimize the charging/discharging protocols, while limited work has been done to address the problem simultaneously, or through a control co-design framework, for a system-level optimum. The control co-design framework is ideal for lithium-ion batteries due to the strong coupling effects between battery design and control optimization. The integration of such coupling effects can lead to improved performances as compared with traditional sequential optimization approaches. However, the challenge of implementing such a co-design framework has been updating the dynamics efficiently for design variations. In this study, we optimize the charging time and cycle life of a lithium-ion battery as a control co-design problem. Specifically, the anode volume fraction and particle size, and the corresponding charging current profile are optimized for a minimum charging time with health-management considerations. The battery is modeled as a coupled electro-thermal-aging dynamical system. The design-dependent dynamics is parameterized thru a Gaussian Processes model, that has been trained with high-fidelity multiphysics simulation samples. A nested co-design approach was implemented using direct transcription, which achieves a better performance than the sequential design approach.

Membrane Electrode

A novel membrane electrode was fabricated by coating conductive slurry (K/Graphene composites as its important component) on copper foil. The membrane electrode, as anode of lithium ion battery, exhibited excellent columbic efficiency and specific capacity of 831 mAh g-1 after 1000 cycles. The K/Graphene composites presented a multi-layer nanostructure. It provided not only more intercalation space and intercalation sites for Li+ during the Li+ intercalation/extraction, but also alleviated the agglomeration of dispersed nanocrystals, as well as decreased the electrochemical impedance. The results suggest that the membrane electrode holds great potential as an anode material for LIBs.
