Wansong SN38-12 12V38AH battery battery wansong DC power battery Recently, Northwestern University research team says it has found a breakthrough in the current lithium-ion battery capacity and charging speed limit method. The new method not only allows a tenfold increase in the amount of charge, the charging time is only one-tenth of the original. It is reported that the results of the study on the phone, Pad, PC and many other electronic products, far-reaching, in particular, can solve the problem of weakness smartphone battery life, provide more convenience for the end user. Related Scientists said the technology is expected in the market within three to five years, the amount of the sale. Lead battery technology development Northwestern University professor Harold Kung and his research team that the charging efficiency, the key technology is that lithium ions between graphene layers in which the ions flow state flow rate directly affects the velocity of the charge speed. In order to accelerate the flow velocity, the team developed a change in the arrangement of graphene, making millions of only 10nm ~ 20nm size bee slotted cylindrical body, to create a "quick shortcut" is more suitable for lithium ion mobility. Because of this, the team realized the original battery charging time will be shortened to 1/10 results. In the charging capacity, the team studied a small group of silicon (Silicon) placed between the graphene layers, reaching enhance internal lithium ion battery density effect. High ductile characteristics thanks graphene provided, such technological breakthroughs also gathered more lithium ions near the electrode, thus making a problem because the silicon old expansion caused resolved. Thus, the use of new technologies Fengyun after fully charged battery, the use of time will be able to maintain a full week. "Now we're going to have to get the best performance both sides." Kung said, because advances in silicon technology industry to achieve higher power storage density, even even if silicon clusters (Silicon Clusters) will not result in the disappearance of the separation of silicon. New technologies still need to improve, but there is still a new battery will be charged 150 times, a sharp decline in efficiency improvements yet this technology. But also pointed out that the increase Kung maintain battery charge (Charge Retention) capacity will be sufficient to make up for this shortcoming, "even though the number of performance remains charged 150 times, but the life expectancy of up to a year or more, not to mention the battery after this still has five times the efficiency of existing lithium batteries. " According to another report, although the technology is considered groundbreaking in the field of a major breakthrough in battery technology, electric storage density has increased to the theoretical limit of about eighty percent, be perfect on the project, but now the project also requires a large amount of investments production.

Wansong SN38-12 12V38AH battery DC power battery news last week: The US decision on China solar panels retroactively impose countervailing duties on January 30, the US Department of Commerce issued a notice in the Federal Register on China solar (panels) double Anti-subsidy cases make an emergency preliminary. US Department of Commerce that the Chinese solar cell manufacturers in the October 2011-December shorter period, exports to the United States a large number of solar cells, the number and amount compared with the period from July to September 2011, surged 15% the above. In order to prevent irreparable damage, the US Commerce Department decided after March 2, 2012 preliminary countervailing duty determination, Going back 90 days start taxing that Chinese imports to the United States after the products involved December 3, 2011 both will be levied countervailing duties, and under normal circumstances, anti-dumping and countervailing duties against imports of the product after the preliminary levy. View: the case of the more obvious early Raisin domestic household photovoltaic power plants and photovoltaic power generation system with fiery tender, and foreign countries government has announced plans to cut solar subsidies or intent, the situation is more obvious Raisin. Traditional European markets, the removal of subsidies in Spain, Italy and liquidity deteriorate, German subsidy policy change change cycle. Domestic market, Golden Sun works, power plant construction in the western region open tender. Wansong SN38-12 12V38AH battery DC power battery wansong SN38-12 12V38AH battery DC power battery this program consists of two parts: PITE3900 intelligent battery status tester; PC machine battery status analysis software. Now its function, usage introduced one below. The program emphasizes the following points: Any change in lead-acid battery life are gradual, frequent measurements did not make any sense, but long-term follow-up management is the most important. Because the average battery life of about five years, measured once a month or so. Currently, some of the expensive battery-line monitoring system is actually not much sense, not to mention its reliability, as it is not monitored object. Lead-acid battery charge and discharge times of life depends on the battery, with the increase in the number of charge and discharge, the battery internal resistance increases, reducing the discharge capacity, when it reaches a certain level, this change accelerated. Therefore, long-term tracking test, state management becomes a viable solution. In actual use, there are many ways to determine the battery life or the state, but the internal resistance based on the measurement method is the fastest, most reliable. Currently exist on the market a variety of so-called capacity detection system (in addition to 10 hours discharge system), in the final analysis are based on the principle of internal resistance. So whether even hundreds of thousands of devices, or tens of thousands, the principle is fundamentally the same, so-called capacity is speculation. Establish a convenient, simple, reliable, low cost and effective testing system, is the ultimate goal of the solution proposed by the company. PITE3900 set a battery tester + software + multiple sets of matching test interface, you can easily regular battery "physical condition" Check, and long-term life-cycle management, ahead of forecast bad battery, the battery life has been avoided due to cause system failures.
