Breaking barriers to China's battery is imminent

 

Electric cars face run short, charging time long mileage "short" problem, China electronic chamber of commerce power professional committee deputy secretary general, lithium ion battery experts QianLiang countries the negativity has pointed out that China has had in a short time, such as lithium ion battery breakthrough new group application technology, and battery energy storage power supply system integration key technical bottleneck technology base, ratchet tie dowm "but these techniques are scattered in colleges and universities to, scientific research institutions and small and medium-sized enterprise hands between enterprises, formed an insurmountable barriers." How to break through the current "separate from each other, and repeat the dispersed of" pattern, has become the electric car power battery field urgent need to address the major issue.


People to new energy vehicle battery status should booster cables not be too pessimistic


The current situation: with the energy saving and new energy vehicles gradually the promoted application, such as lithium ion battery electric vehicle integrated into new, safety plunged, battery clip service life greatly shorten the problem emerges; Battery fires and explosions of frequent malignant accident, have seriously restricted the energy saving and new can auto industry development. Shenzhen 50 a pure electric taxi demonstration operation one year, loss of more than 7 million yuan, the scale of application of the shadow was added.tow rope Energy saving and new energy excessive pessimistically power battery energy storage system key technology breakthrough the mood of the prospect is still in development.


Battery energy storage power system, it is energy-saving environmental protection industry, new energy industry and energy saving and new energy vehicles industry (hereinafter referred to as the energy saving and new energy industry) key common technology and the common foundation to support industry. Battery energy storage power technology has become energy saving and new energy industry competition in focus. Master the battery energy storage power industry of the initiative and have the energy saving and new energy industry initiative. Energy saving and new energy vehicles is most likely the application is still the lithium ion battery.


In the country industrial policy and "863" and "973" projects such as the key support, the lithium ion battery key technology, key materials and industrialization major progress has been made in the research. Among them, the large capacity energy type lithium ion battery industry development has is an international leader.


Monomer large capacity energy type of lithium ion battery performance has been basically can meet the scale of the basic conditions for the application. Although manufacturing cost is still higher than the valve control lead batteries, single from the life cycle economy consideration, has significantly better than valve control lead batteries. Monomer battery performance, from the whole life cycle of economy and industrialization base consideration, large capacity energy type lithium ion battery already have a large-scale promotion application of basic conditions.


The main problem is: the lithium ion battery and so on the new group, safety plunged, service life greatly shorten, even burning, frequent battery explosion etc malignant accidents. The battery is always the electric car and energy saving and restricts the development of new energy industry, the technical bottleneck.


From battery group application technology, and battery energy storage power supply system integration technology situation to consider, in the technical bottleneck before the break, the electric car is still do not have become widely accepted and industrialization of basic conditions.


Break the battery between enterprises "barriers" already is imminent


Bottleneck: the problem though performance in the battery, but the root of the problem lies in battery technology and application in battery energy storage power supply system integration technology can't meet the lithium ion battery and so on the new requirements. Battery group application technology, and energy storage power supply system integration technology, is restricted and new energy cars including energy saving, energy saving and new energy industry development the technical bottleneck. Lithium ion battery breakthrough and so on the new group application technology, and battery energy storage power system integration key technology, including the energy saving and to promote new energy vehicle, the energy conservation and the development of new energy industry major issue.


Source: battery energy storage power supply system key technology research no substantial progress, there are technical reasons, also have non-technical reasons.
