Sunlight as the energy solar street lamps, solar energy during the day battery board for battery charging, the battery at night to power supply using light source, without complex and expensive pipeline laid, can be arbitrary adjust the layout of the lamps and lanterns, safety and energy saving no pollution, no manual work is stable and reliable operation, saving electricity free maintenance, solar street light for a loop at the same time, without having to worry about as ordinary street lamp line is broken and overall is not bright Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery, gel battery) to store electrical energy, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps.

Recently, it is reported that major breakthroughs were made in Huawei graphene battery maxed out battery industry circle of friends "The first high temperature long life graphene lithium ion batteries"" service life is 2 times of the normal lithium ion battery" statements shock the public at the moment.

Over 90 household smart security fingerprint lock on the market at present is charged by the battery power supply According to the manufacturer introduction, 8 dry cells can be used for more than one year, while 4 batteries are around 8 months.

The lithium battery discharging termination voltage is related to lithium battery cycle life, which is one of the most important application parameters Therefore, we should first clarify the meaning of this concept:1, the lithium battery at this moment is referring" Lithium ion batteries", because habits, daily life people often put the lithium ion battery colloquial for lithium-ion batteries, this is the place where differs from professional term application,2, lithium battery discharging termination voltage refers to the lithium battery discharge after a certain voltage, unfavorable to discharge, otherwise it will cause some power lithium batteries are not reversible loss, serious damage to the battery.

With the development of Chinese economy, more and more Chinese products enter the international market On the other hand, in the face of various types of products, especially dangerous goods such as lithium batteries, the customs regulations on imported goods are very strict.

The electrode junction of the battery is a place where problems are likely to occur this season, so pay attention to checking at any time Check every part of the circuit for aging or short circuit.

80 % of accidents in lithium-ion batteries are caused by short circuits After short circuits, batteries are caught in flames and explosions are frequently reported.

The all-solid lithium secondary battery has attracted the attention of the international giants because it is expected to solve the two "challenges" currently plaguing the power battery industry: safety hazards and low energy density The advantages of all-solid lithium batteries over liquid lithium ion batteries include:(1) High safety performanceSince the liquid electrolyte contains flammable organic solvents, sudden temperature rise in the event of an internal short circuit can easily cause combustion or even explosion.

As we all known, pure electric vehicle power is output by battery The battery management system (BMS) is one of the cores, and is responsible for the control of the battery charging and discharging, battery state estimation and other functions.

At present, lithium-ion batteries are widely used For example, the main lithium-free electronic batteries in modern mobile smart terminal products are completed.
