People have life and death, and lithium battery can be produced and threw away People call this phenomenon as the cycle life of lithium battery.

lead-acid The battery and The lithium batteryLead-acid battery is the most cheap, but big volume, heavy weight, short service life.

The stability of lithium iron phosphate battery at high temperature can reach more than 390 ℃, which guarantees the high security, so that the battery will not lead to explosion or cumbustion due to overcharge, high temperature, short circuit and impact It can easily pass the needle thorn experiment.

Lithium-ion batteries, as well as whole samples of non-user replacement batteries/lithium-ion batteries and their electronic products For non-user replacement batteries, they should be installed in electronic products as a whole sample for environmental safety test of lithium-ion batteries in the standard; for non-user replacement lithium-ion batteries, they can be placed in electronic products as a whole sample, or can be taken out separately for environmental safety test of lithium-ion batteries in the standard, recommending preferential choice.

It was first used in cardiac pacemaker The self-discharge rate of lithium battery is very low and the discharge voltage is flat.

Electrode materials have volume expansion/contraction in the process of embedded/lithium off, and the volume effect can result in material crushing failure Therefore, the electrode material in the process of charging and discharging cycle structure is stable, which has a crucial influence on battery capacity, rate and cycle life performance.

The battery is mainly lithium as the other pole These batteries generally use liquid electrolyte.

 Foreword: In September 2018, power battery production totaled 70GWh, a sequential increase of only 4.

The battery module can be understood as a lithium ion battery core combined in series and parallel mode, and an intermediate product of a battery core and a pack formed after the unit battery monitoring and management device is installed Its structure must support, fix and protect the battery core, which can be summarized into three major items: mechanical strength, electrical performance, thermal performance and fault handling capability.

From the point of view of use, there is no qualitative difference between the two types of batteries The maintenance-free battery has been charged with the electro-hydraulic at the time of shipment, and the water-added battery is added at the time of purchase; The maintenance-free battery does not need to add pure water throughout the life of the life.
