Solar power blade, graphene, 'cobalt free batteries,' who is the future of the power battery

At this year's two sessions, the development of new energy vehicles again brought to the attention of the countries and representatives of the government work report, will focus on support to promote consumer's livelihood and adjustable structure increases the staying power of & other; Two new throughout a heavy &; Construction, mainly is to strengthen the construction of the new infrastructure, development of a new generation of information network, expand the 5 g applications, charging pile construction, the promotion of new energy vehicles, inspire new consumer demand, the power industry upgrading.

at present, our country has for several years to become the new energy automobile production and sales of the first countries, it also promote the development of the power battery industry in China, our country also has become the battery supply of the world's biggest market. Battery as core driving force for the development of new energy vehicles industry, already is not only a simple competition in terms of energy storage and energy density. How to better ensure the battery problems, such as durable, reliable, cost and environmental protection gradually become a new industry development.

with the increase of industry demand, technological progress and the competition, the market for iterative battery technology, also towards diversification, and technological development. Recently, the battery industry bombshell, byd's blade batteries, nest group & other Cobalt free & throughout; Batteries, coupled with the gac announced that graphene breakthroughs in battery technology, solar energy equipment, time, battery technology presented the & other; Schools of thought contend & throughout; Cheng jing. Not only affects consumers, also affects the capital market.

in the first half of 2020, although the disease reduces the temperature of the auto market, but power battery industry has been white-hot competition, in recent days is big news.

on March 29, byd launched a blade cell, shows the battery in the conference's most afraid of needle test, and announced that the blade battery with high safety, long life, long life and other characteristics, the development route of the power battery back based on safety on the road.

on May 13, the gac group, guangzhou new energy announced: the end of the year, graphene battery production research and development work will be from the lab to the real vehicle, the gateway to solar energy, solar energy portal, guangzhou new energy Aion will carry relevant technological achievements. It is reported, & other; Based on the gac three-dimensional structure of graphene ( 3DG） & other materials research and development; Super quick charge battery & throughout; Has completed cell and module, the battery pack sample test work, and pick up the vehicle to carry on the high power charging the load test, have to use the standard battery life and safety. According to the test, & other; Super quick charge battery & throughout; Only eight minutes can be the battery to 85%, charging time and the traditional fuel vehicles come on time.

Great Wall's issued by the beehive energy technology on May 18, the so-called global first cobalt free power battery. The battery products, the biggest characteristic is in the anode material thoroughly remove the rare metal cobalt, makes original ternary lithium nickel manganese cobalt acid, turned into a binary lithium nickel manganese acid. According to introducing, this will effectively reduce the cost of batteries, while beehive energy hong-xin Yang, general manager in an interview with reporters, said in 600 km - cobalt free batteries 800 km range of the subdivided market more competitive.

and on June 10, ningde era also announced that to produce a life for 16 years, the total range of 2 million kilometers of the battery.

at first, in the field of power battery technology mainly concentrated in the lithium iron phosphate batteries. By 2012, however, as the country put forward the clear indicators, the energy density of batteries battery energy density higher ternary lithium battery has been used more and more auto makers to new energy automotive products. More and more auto makers to get subsidies, turning to the ternary lithium battery. In 2015, even in research and development of lithium iron phosphate batteries byd began using the ternary lithium battery, power battery as a new energy automobile products.

in fact, and the ternary lithium batteries, lithium iron phosphate is mainly refers to the level of the batteries are material. The difference between the two is that the energy density of lithium iron phosphate battery is low, but higher stability, relatively safe, China solar energy network, mostly used to take a bus; And the ternary lithium battery energy density is higher, but the cost is higher also, therefore, in state and local subsidies, car companies more willing to put the ternary lithium battery assembly on the new energy vehicles. However, as in 2019, the state subsidy policy began to greatly TuiPo, power battery industry white list has been cancelled, the choice of car companies change again, subsidies TuiPo mean automakers cost increase, so the lower cost of lithium iron phosphate battery to get the favour of car companies; And the cancellation of the white list, cause overseas battery supplier to join in the domestic market competition, also promoted the domestic battery companies seek technical breakthrough, to gain the market power.

it all, spawned in the first half of 2020 the power battery competition heats up. Cui Dong tree that subsidies TuiPo although led to the new energy car sales fell nearly a period of time, but as the national policy developed, solar power grid, new energy automobile market in China is developing in the direction of the market as the guidance. The half-year power battery technology is gaining new breakthrough is illustrate this problem.
