As the life span of EV batteries needs to be more than 10 years and the product development time is limited, an accelerated life span testing is often used to assess the long-term performance of the batteries. In this work, we prepared NCM811 cathode material through co-precipitation and high-temperature calcination and stored NCM811/Graphite pouch-type full cells at 60 ℃ in a fully charged state for the investigation of their storage performance. It was found that the storage capacity of the cells decreased to 80% after 180-day storage. XRD, SEM, ICP-AES, XPS and HRTEM techniques were used to investigate the differences between freshly made and the degraded electrodes. The results demonstrated the formation of by-products on the surface of cathode, and cathode materials exhibited layered-spinel-rock salt phase transformation after storage, both greatly increased the cell impedance. In addition, transition metal ions dissolved from the cathode were found to accumulate on the anode, which may have destroyed the SEI, leading to the consumption of the active lithium. Surface coating and bulk doping could resolve the problem through stabilizing the surface and bulk structure of the cathode materials. Reference | Related Articles | Metrics | Comments（0）

Inflection point Ah-total integration method for real-time integration to correct lithium battery SOC LIU Dong, HUANG Bixiong, WANG Yiquan, YAN Xiao, WANG Ying Energy Storage Science and Technology    2019, 8 (5): 850-855.   DOI: 10.12028/j.issn.2095-4239.2019.0067 Abstract （815）      PDF（pc） （588KB）（3202）       Knowledge map    Save The data of charge and discharge current and voltage of 18650 and 26650 lithium iron phosphate batteries show that the voltage remains unchanged during the cycle aging of the battery, although the SOC value at the maximum curvature (inflection point) of the capacity voltage curve. Therefore, in the process of estimating SOC, when the discharge voltage reaches the inflection point voltage, modifying the SOC to the corresponding inflection point SOC can optimize the estimation of the ampere-hour integration method because of the initial SOC to a certain extent. Based on this, a new inflection point correction chronograph integration algorithm is proposed. The effects of temperature, charge and discharge ratio, cycle aging and other factors on the accuracy of SOC estimation are considered. The concept of inflection point of charge and discharge curve is introduced to establish a mathematical model for real-time estimation of SOC. To reduce the cumulative error problem of the ampere-time integral method. Compared with the traditional An-time integral method, the error is 3%, which indicates that the method is feasible in actual conditions, and the estimation accuracy is high, which can provide an important reference for real-time estimation and detection of SOC.

All-solid-state lithium-ion batteries based on polymer electrolytes: State of the art, challenges and future trends DU Aobing, CHAI Jingchao, ZHANG Jianjun, LIU Zhihong, CUI Guanglei Energy Storage Science and Technology    2016, 5 (5): 627-648.   DOI: 10.12028/j.issn.2095-4239.2016.0020 Abstract （1431）      PDF（pc） （24845KB）（3020）       Knowledge map    Save The traditional rechargeable lithium batteries commonly used a large amount of non-aqueous liquid electrolytes leading to inherent hazards of leakages and fire. All-solid-state polymer electrolytes (ASPEs) attract intensive interests due to their unique properties, such as high safety characteristics, wide operating temperature range and long cycle life. They are expected to be the next generation of commercialized electrolytes in the field of lithium-ion battery. The dendritic growth of lithium metal electrode can also be well suppressed in the process of charging and discharging by ASPEs, because ASPEs usually have excellent mechanical properties. This review presents a brief overview of recent progress in ASPEs based on polyethylene oxide(PEO), polycarbonate, polysiloxane and single lithium-ion conductor. PEO is the first class of ASPEs that are researched extensively, whose high crystallinity give rise to the difficult migration of Li+ and low ion conductivity. Aimed at the issue of crystallinity, researchers have exploited plenty of modifications to lower polymer chains’ crystallinity and improve the conductivity of PEO. Lithium salts are easily dissolved in polycarbonates and resulted polymer electrolyte has higher ion conductivity than PEO because of its strongly polar carbonate group and amorphous state at room temperature, which may be alternative materials of PEO potentially. Besides the carbon-chain polymers, polysiloxane with low glass transition temperature attracts widespread concerns from researchers because of its high conductivity. In addition, migration of anions will only exacerbate concentration polarization of electrolytes in the charge-discharge process, so single lithium-ion conductors without anions’ migration are also worth to exploiting. Finally, the challenges and future trends towards high energy and all-solid-state polymer electrolytes batteries are also commented. PEO should be developed with the organic-inorganic composite system, polycarbonate should be developed with the blend system, polysiloxane should be enhanced with strong mechanical properties, single lithium-ion conductor should be designed with the new polyanion lithium salt that has higher conductivity.

Cost analysis of hydrogen production by electrolysis of renewable energy GUO Xiuying, LI Xianming, XU Zhuang, HE Guangli, MIAO Ping Energy Storage Science and Technology    2020, 9 (3): 688-695.   DOI: 10.19799/j.cnki.2095-4239.2020.0004 Abstract （3092）   HTML （174）    PDF（pc） （3084KB）（2892）       Knowledge map    Save In this paper, the cost of hydrogen production by renewable energy electrolysis was systematically analyzed, and the levelized cost of hydrogen (LCOH) from alkaline and PEM electrolyzers were compared. The effects of scale, hydrogen pressure, compression and liquefaction, and input power fluctuation on the cost of hydrogen production by alkaline and PEM electrolysis were investigated. The results showed that the cost of hydrogen production was reduced with the increase of scale. When the scale of our investigated electrolysis system was increased from 1 MW to 40 MW, its fixed cost was reduced by more than 40%, but its LCOH cost was reduced byless than 25% because electricity is the main cost. The LCOH cost of hydrogen production by high-pressure electrolysis can be significantly reduced without increasing the fixed cost. With the increase of electrolysis pressure from 1 atm to 30 atm, the cost of hydrogen further compression to 700 atm will be reduced from 1 $/kg to 0.3 $/kg. The liquefaction cost was significantly affected by the scale, and the levelized cost of hydrogen production by electrolysis and liquefaction decreased from 8.7 $/kg to 5.3 $/kg with the increasing of scale from 1 MW to 40 MW. For PEM has good adaptability of renewable energy fluctuation, the LCOH cost of PEM could be lower than that of alkaline electrolysis with an increase of low power (<20% rated power) fluctuation. With the improvement of alkaline electrolysis and PEM electrolysis technology, which is better or worse should be discussed according to the specific situation.
