1 天前· Lithium-ion batteries are indispensable in applications such as electric vehicles and energy storage systems (ESS). The lithium-rich layered oxide (LLO) material offers up to 20% higher energy density than conventional nickel-based cathodes by reducing the nickel and cobalt content while increasing the lithium and manganese composition.
This discovery could improve the performance and life expectancy of a range of rechargeable batteries. Lithium-ion batteries power everything from smart phones and laptops to electric cars and large-scale energy storage facilities. Batteries lose capacity over time even when they are not in use, and older cellphones run out of power more quickly.
Comparison of lithium-ion battery life prediction methods. The data-driven method establishes a prediction model based on the statistical laws of historical data, without considering the physical and chemical reactions inside the battery, and can quickly predict the state and life of the battery.
External and internal influence factors affecting the lifespan of power lithium-ion batteries are described in particular. For external elements, the affect mechanisms of the operating temperature, charge/discharge multiplier, charge/discharge cut-off voltages, the inconsistencies between the cells on the service life are reviewed.
Therefore, the experiment data showed that power lithium-ion batteries directly affected the cycle life of the battery pack and that the battery pack cycle life could not reach the cycle life of a single cell (as elaborated in Fig. 14, Fig. 15). Fig. 14. Assessment of battery inconsistencies for different cycle counts . Fig. 15.
The current research on power battery life is mainly based on single batteries. As known, the power batteries employed in EVs are composed of several single batteries. When a cell is utilized in groups, the performance of the battery will change from more consistent to more dispersed with the deepening of the degree of application.
The health status of lithium-ion batteries is limited by various factors such as capacity, internal resistance, and multiplicity. The estimation of the SOH of lithium-ion batteries can effectively determine the real-time and future operating conditions within the battery and is of great research importance.

But, in a solid state battery, the ions on the surface of the silicon are constricted and undergo the dynamic process of lithiation to form lithium metal plating around the core of silicon. "In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle," said Li.
