As a new type of energy storage device, lithium batteries are now used in all aspects of life.Firstly, you must consider for what you want to use a battery from the following perspective :

Power lithium batteries have steadily occupied the position of the leader in the power supply of electric vehicles. Long service life, high energy density, and great potential for improvement. Safety can be changed, and energy density can continue to rise. It can catch up with the endurance and cost-effectiveness of fuel vehicles. However, lithium batteries also have the troubles.

Graphene battery is considered to be one of the most potential materials in the future, but for now, its foam composition is greater than the actual application value. There are many factors hindering the popularization of this material. Mass production and cost are the main obstacles to popularization. Graphene batteries have a long way to go before they can completely replace lithium batteries in the short term.

It is best not to charge lithium batteries in winter. This is mainly because the charged lithium ions on the surface of the negative electrode are easily deactivated at low temperatures to generate dendritic lithium crystals, which directly pierce the diaphragm. It will cause a short-circuit of the battery and affect the life and performance. In severe cases, it will cause an explosion.
