Information

Storage temperature -40% charged state -------100% charged state
0 degrees -------------98%------------------94%
25 degrees -----------96%------------------80%
40 degrees -----------85%------------------65%
60 degrees -----------75%------------------60%

It can be seen from this that the higher the storage temperature and the fully charged the battery, the more severe the capacity loss will be. Therefore, it is not recommended to store lithium-ion batteries for a long time. If users have idle batteries in hand, the recommended storage conditions are a charging level of 40% and a storage temperature below 15 degrees or even lower.

Graphene puts a fireproof coat on energy storage lithium batteries [ 2025-09-29 ]

Graphene dresses energy storage lithium batteries in a "fireproof coat", reducing the explosion coefficient of electric vehicles

Conduct a thorough analysis of the impact of temperature on lithium iron phosphate batteries [ 2025-09-29 ]

Lithium-ion batteries have numerous advantages, such as high working voltage (three times that of nickel-metal-hydride and nickel-cadmium batteries), large specific energy (up to 165Wh/kg, three times that of nickel-metal-hydride batteries), small size, light weight, long cycle life, low self-discharge, no memory effect, and no pollution. Lithium iron phosphate batteries are highly favored in the new energy industry. With a cycle life of around 3,000 times and stable discharge, they are widely used in power batteries and energy storage fields.

The wide application of lithium-ion batteries in various fields [ 2025-09-29 ]

It is well known that new market demands for lithium-ion batteries are taking shape very rapidly. Lithium-ion batteries are currently divided into three major categories. The first is consumer electronic products. Nowadays, lithium-ion batteries are widely used in mobile devices such as smartphones and laptops. The market capacity of this market can basically be calculated in the hundreds of billions. The second is the emerging demand for electric vehicles. Whether it is pure electric vehicles or plug-in hybrid vehicles, the current demand has gradually taken shape. Thirdly, lithium batteries will be used in the field of energy storage in the future. Its market capacity will be even broader than that of electric vehicles, and its market can even be measured by a value of trillions.

The composition of the positive and negative electrodes of lithium batteries [ 2025-09-29 ]

Lithium batteries usually come in two shapes: cylindrical and square. The interior of the battery adopts a spiral winding structure, with a very fine and highly permeable polyethylene film isolation material separated between the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobalt oxide (or lithium nickel cobalt manganese oxide, lithium manganate, lithium iron phosphate, etc.) and aluminum foil. The negative electrode is composed of a current collector made of graphitized carbon material and copper foil. The battery is filled with organic electrolyte solution. In addition, it is equipped with safety valves and PTC components (some cylindrical types are used) to protect the battery from damage in case of abnormal conditions or output short circuits. The voltage of a single lithium battery is 3.7V (3.2V for lithium iron phosphate cathode), and the battery capacity cannot be infinitely large. Therefore, single lithium batteries are often connected in series or parallel. To meet the requirements of different occasions.

What is the charging and discharging process of lithium batteries like [ 2025-09-29 ]

The cathode material of a battery accounts for 30% to 40% of the cost of a lithium battery.
