The number of waste lithium-ion batteries has increased rapidly as well as their use in the field of transportation, energy storage and portable equipment, which has aroused concerns about environmental pollution and metal resources [1,2,3,4,5,6,7,8,9].Research indicates [] that lithium-ion battery-related waste will exceed 11 million t from 2017 to 2030.
Especially in the case of adding high-capacity silicon-based anode materials to graphite, this kind of active lithium loss leads to an extremely low-first cycle coulomb efficiency and battery capacity.

Lithium-ion batteries have emerged as a promising alternative to traditional energy storage technologies, offering advantages that include enhanced energy density, efficiency, and portability. However, challenges such as limited cycle life, safety risks, and environmental impacts persist, necessitating advancements in battery technology.
To mitigate the ALL (ALL = iALL + cALL) issue and improve the energy density of current LIBs, a promising approach is through the implementation of a lithium replenishment strategy by storing an extra amount of lightweight active-lithium
Lithium battery energy storage occupies more than 90% market share in the current new energy storage, which is the mainstream technology route. For lithium battery energy storage, extending battery life and reducing capacity degradation is an important technical breakthrough direction. The reporter learned at the summit that lithium replenishment
The cycling performance of the pouch cell at 0.5C is shown in Fig. 4g. After 500 cycles, the cell maintains a discharge capacity of 130.2 mA h g −1, with a high capacity retention of 90.49%. These results indicate the promising potential of our lithium replenishment method for energy storage applications.
Our innovative long-term lithium replenishment method ensures a sustained and controlled release of lithium ions throughout the battery's lifespan, effectively mitigating both the capacity loss arising from iALL and the capacity degradation associated with cALL, thus significantly extending the cycle life of LIBs.
To address long-term capacity degradation resulting from cALL, we propose a lithium replen-ishment strategy designed to enhance the cycling performance of lithium-ion batteries (LIBs) throughout their entire lifecycle.
Several methods of lithium polymer lithium battery replenishment The common pre-lithiation method is to supplement the negative electrode with lithium, such as lithium foil supplemented with lithium, lithium powder supplemented with lithium, etc., which are all pre-lithiation processes that are currently being developed.
In this approach, we introduce the concept of the “lithium replenishment degree” (LRD) to quantitatively measure the surplus amount of active lithium ions available for compensation. The LRD is calculated as the ratio of the capacity of the sacrificial lithium reservoir to the capacity of the cathode:
To enable lithium compensation throughout the entire cycle life of the batteries, it is necessary to introduce a higher LRD into the batteries, with the surplus LRD serving as a reservoir of lithium gradually released during extended cycling.
