1, Battery

The Korea Electronics and Communications Research Institute (ETRI) has successfully developed an all-solid cathode material for secondary batteries,

 The institute said Wednesday( 21.7.14), Radio Korea International reported.

The positive electrode of the all-solid secondary battery consists of a solid electrolyte that allows lithium ions to move smoothly within the electrode and an active substance responsible for energy storage.However, with the increase of solid electrolyte ratio, there are relatively few active substances, and the increase of energy density is limited.

The research team developed a new electrode structure that uses only titanium disulfide (TiS2) as the active material and does not use a solid electrolyte to form the positive electrode.

The amount of the active substance can be increased without the use of solid electrolytes, and the energy density can be increased by over 1.3 times compared with the use of solid electrolytes of the same capacity, according to the report.

Because the existing liquid electrolyte used in the secondary battery has the risk of fire and explosion, the all-solid secondary battery using solid electrolyte has attracted much attention as a new generation battery.

The results of the study, conducted in collaboration with Professor Rongmin Li of Daegu Gyeongbei Institute of Science and Technology (DGIST), are published in the online edition of Energy Storage Materials (June), an international academic journal in Materials science.

2, Fuse

(1), In Electrical vehicle energy storage market

The energy storage of new energy vehicles adopts high-voltage direct current, and the over-current protection is mainly completed by high-performance fuses.

In the process of long-term movement of vehicles, the working environment of the circuit is complex, and it needs to withstand mechanical vibration, temperature change, chemical corrosion, current impact, vehicle collision and other conditions. The above conditions are highly likely to cause short circuit fault. In the vehicle current system, if there is a short circuit accident, it may produce a short circuit current of more than 10kA, which can not be broken reliably by other components of the vehicle at present. If the short-circuit current lasts for tens of milliseconds, it will destroy important devices in the vehicle system loop, such as power batteries, conductors, load devices, etc., causing great economic losses. If serious, it will cause fire and secondary injury, endangers life safety.

The  EV fuse  can quickly cut off the circuit when the short circuit current occurs, prevent the expansion of the accident and protect the safety of property and life. It is an essential safety protection device in the circuit system of new energy electric vehicles.

New energy electric vehicles increased demand for  electric power fuses. Automotive fuse divided into two parts, low voltage and high voltage, low voltage fuse applications are usually less than 60 VDC, mainly electronic fuse such as  70VDC fuse, low voltage loading of motor protection, such as light, window motor, wiper motor, speaker, etc, this kind of protection on the traditional vehicles and new energy vehicle are also applied. 

DC High voltage fuse protection is mainly suitable for new energy vehicles. The application voltage is generally 60VDC to 1,500VDC. It is mainly the  power fuse (high voltage fuse of new energy electric vehicles) to protect the main circuit and auxiliary circuit.

(2) New energy solar power generation and energy storage market

With the rapid growth of renewable energy installation, renewable energy storage has become a trend. Because the new energy wind-solar power generation has the characteristics of volatility, intermittence and unpredictability, the combined energy storage system can better reduce and smooth the fluctuation, and achieve higher efficiency.

The direct output current of new energy solar power generation does not match the power transmission network. If the power is transmitted through grid-connected (AC high-voltage network), the current needs to be converted into alternating current by the inverter and transmitted to the power grid. The power of new energy wind-solar power generation fluctuates greatly, so it is necessary to configure an energy storage system to achieve peak-valley power balance. Among them, the power of photovoltaic power generation is generally increased through a confluence system due to the small power of a single cell. All power generation system, converter system energy storage system  need  control system  to cooperate.
