However, with the increasing demand for safe transport and green recycling of lithium-ion batteries, over-discharge protection and even zero-volt protection have a broad application in more working devices. Over-discharge causes severe Cu dissolution and SEI degradation, which is mainly attributed to the raised anode potential.
The demand for high safety and high reliability lithium-ion batteries (LIBs) is strongly considered for practical applications. However, due to their inherent self-discharge properties or abuse, LIBs face the threat of over-discharge, which induces premature end of life and increased risk of thermal runaway.
Therefore, the arc extinguishing capacity of ESC protection device in the battery module should be matched with the module voltage level to ensure the safety of the breaking process. In conclusion, a fuse protection design is required for lithium-ion battery modules even if there is no fire or explosion during ESC of a single cell.
Lithium-ion batteries (LIBs), in general, offer high energy densities compared to many alternative energy storage devices. The specific energy (Wh kg −1) of lithium-ion batteries is derived from the specific capacity (the amount of charge that can be stored per unit mass) and the operating potential.
1. Introduction Due to the advantages of high energy density, high power density, low self-discharge, and long cycle life, lithium-ion batteries have been playing an increasing role in the field of electric vehicles and new energy storage systems.
Lithium-ion battery-powered EVs can classically travel a certain distance only before their batteries need to be replaced. A battery charging system and a new battery control strategy are necessary for EV applications because of the limited usable range.
