In most cases, primary protection response is sufficient. However, secondary protection is necessary for lithium-ion batteries, since the consequences of a failure are serious. The temperature of a rechargeable battery usually rises as the battery charge progresses.
The lithium-ion technology offers a high energy and power density, long life, and reliability that makes it attractive for electric drive vehicle (EDV), military, and aerospace fields, and large format Li-ion cells and battery packs are currently under development for such applications.
Lithium-ion batteries (LIBs) have been widely used in portable electronics, electric vehicles, and grid storage due to their high energy density, high power density, and long cycle life.

Conclusive summary and perspective Lithium-ion batteries are considered to remain the battery technology of choice for the near-to mid-term future and it is anticipated that significant to substantial further improvement is possible.
There is a steady increase in the demand for lithium-ion batteries for all portable electronic devices (almost 100% of cell phones and notebook PCs), and in addition, the Li-ion system also started penetrating more and more in other arenas like power tools, energy storage systems (ESS) , and so on.
