Li₄Ti₅O₁₂‐Based Battery Energy Storage System with Dual‐Phase Cathode

Energy Technology (2022)

Weijing Yang Maohui Zhang Shangde Ma Ying Luo Bangling Zhang

Lithium‐ion batteries with spinel Li 4 Ti 5 O 12 materials as anode, which can offer fast charge times, high power output, superior safety, and long life, are considered to be a competitive choice for grid‐scale energy storage systems (ESS). Herein, a 10 Ah lithium–titanate battery with lithium cobalt oxide–lithium nickel cobalt manganese oxide dual‐phase cathode is developed and its application in 100 kWh‐level ESS is investigated. The 10 Ah single battery demonstrates a specific capacity of 79 Wh kg −1 with a high‐capacity retention rate of 91.8% after 1000 cycles at 55 °C and >80% capacity retention at 15 C cell . The 125 kWh ESS shows an energy efficiency of 97.82% and 89.97% at 0.2 and 1.5 C System , respectively. Self‐discharge and constant power tests indicate that the battery system is stable, thus suitable for storing intermittent power from renewable sources such as solar and wind. The system's ability of smoothing the fluctuated power is confirmed by coordinating with a wind power system.

Thermal Behavior of Lithium Ion Battery for SAR Satellites

2021 2nd China International SAR Symposium (CISS) (2021)

Ya Mao Wan Bingxin Shangde Ma Rui Guo Jingying Xie

For the improvement of the safety and reliability requirements of lithium ion batteries for space system, we have researched the thermal characteristic of NCA/C lithium ion battery for the large power synthetic aperture radar (SAR) satellites. The electrochemical performance and heat generation behavior under different states were studied. The charge and discharge processes of NCA/ graphite battery are exothermic in different currents, and the total heat increases with the current rate, as tested by Accelerating Rate Calorimeter.

Evaluation of Heat Generation and Thermal Degradation of Lithium Ion Batteries by a Calorimetry Method

Journal of The Electrochemical Society (2021)

Ya Mao Rui Guo Liangmei Sheng Shangde Ma Luozeng Zhou

With the wide application of lithium-ion batteries (LIBs), it is important to understand the internal heating effects and thermal runaway behavior of such batteries to evaluate their thermal safety and improving thermal management systems. The heat generation of LiCoO2/graphite LIBs under various conditions was compared using calorimetry and electrochemical methods. The heat generation results of the two methods in the process of charging/discharging at different current rates were consistent, but the calorimetry method is simple, convenient, and more feasible. The greater the working current, the greater the irreversible heat generation. Through the identification of the thermal runaway behavior, it was found that the change of the onset temperature of self-heating reactions fluctuates in a narrow range. Thermal runaway after battery degradation is more likely to be triggered by the degradation of thermal stability.
