The effects of carbon black specific surface area and morphology were investigated by characterizing four different carbon black additives and then evaluating the effect of adding them to the negative electrode of valve-regulated lead–acid batteries for electric bikes. Low-temperature performance, larger current discharge performance, charge acceptance, cycle life and water loss of the batteries with carbon black were studied. The results show that the addition of high-performance carbon black to the negative plate of lead–acid batteries has an important effect on the cycle performance at 100% depth-of-discharge conditions and the cycle life is 86.9% longer than that of the control batteries. The excellent performance of the batteries can be attributed to the high surface area carbon black effectively inhibiting the sulfation of the negative plate surface and improving the charge acceptance of the batteries.

Discharge rate is a key parameter affecting the cycle life of lithium-ion batteries (LIB). Normally, lithium-ion batteries deteriorate more severely at a higher discharge rate. In this paper, we report that the cycle performance of LiNi0.8Co0.15Al0.05O2/graphite high-energy 2.8 Ah 18650 cells is abnormally worse at a 1.5 C discharge rate than at a 2.0 C discharge rate. Combining macromethods with micromethods, the capacity/rate performance, electrochemical impedance spectroscopy (EIS), and scanning electron microscope (SEM) morphology of the electrodes are systematically investigated. We have found that the impedance of the negative electrodes after 2.0 C aged is smaller than that after 1.5 C aged, through EIS analysis, and the discharge rate performance of the negative electrodes after 2.0 C aged is better than that after 1.5 C aged through coin cell analysis. In addition, some special microcracks in the negative electrodes of aged cells are observed through SEM analysis, which can accelerate the side reaction between active and electrolyte and form the thicker SEI which will hinder the Li+ insertion and cause resistance increase. In short, the LiNi0.8Co0.15Al0.05O2/graphite-based lithium-ion batteries show better cycle life at a 2.0 C discharge rate than at a 1.5 C discharge rate which indicates that the negative electrodes contribute more than the positive electrodes.

Solid polymer electrolytes (SPE) have attracted wide attention of researchers because of their high safety performance and high mechanical strength. In this paper, holey graphene oxide (HGO) was added to poly(ethylene oxide) (PEO) solid polymer electrolytes with lithium bis(trifluoromethane sulfonimide) (LiTFSI) as salt to improve the ionic conductivity of solid polymer electrolytes. It was shown that the addition of holey graphene oxide improved the electrochemical window and ionic conductivity. When the amount of holey graphene oxide was 0 wt%, the ionic conductivity was 2.06 × 10–4 S/cm at 60 °C. In comparison, when the amount of holey graphene oxide was 0.2 wt%, the ionic conductivity was greatly increased to 6.05 × 10–4 S/cm. This was mainly due to the fact that addition of holey graphene oxide reduced the crystallization of polymer and promoted the migration of lithium ion. Meanwhile, the electrochemical window was expanded to 5.2 V and the cycle performance for the batteries was also improved.
