The application of lithium titanate in energy storage

Development of renewable energy industry is the important pillar of green energy development. 2017 is a year with rapid development of Chinese renewable energy, but also a year with rapid advanced global energy change.

Data show that by the end of 2017, China's hydropower reached 340 million kilowatts of power, wind power capacity of 164 million kilowatts, photovoltaic power generation capacity of 130 million kilowatts, renewable energy generation accounted for 26% of all electricity generated. Visible, China's renewable energy power generation have made substantial progress.

Energy storage with renewable energy is like a pair of "twin", so, energy storage exactly is what industry, some analysis, energy storage accounts for 10% to 15% of the electricity industry. Renewable energy in 2050 reached 80%, no energy storage how to achieve this goal, if renewable energy is the energy of uncontrolled, how to achieve 80%?The industry believes that the market price mechanism is the key to the development of energy storage, so, through what policy, reflect the value of the power grid stability. Deputy director of the institute of Chinese academy of engineering thermal physics/Zhongguancun energy storage industry technology alliance director Chen hs believes that "have confidence in the development of systems and mechanisms, the development of energy storage technology itself have faith."

If yes, any enterprises have no confidence to the industry, and how to do? Today, for you to say the company - silver long new energy co., LTD. (hereinafter referred to as the "silver long new energy") in the storage market crafted over ten years,

During this decade, silver long new energy what happened? The development of energy storage technology is how to?

Energy storage technology from the United States the titanium silver long new energy has been reserve energy storage

The international market is prosperous. Energy storage technology of the new energy comes from the United States Olympic silver titanium company (hereinafter referred to as "titanium"), the most valuable of the titanium technology in energy storage, in December 2007, the titanium power company AES sales to the United States for two 1 mw frequency control system, in 2009 formally put into commercial operation, and the success of the validation will be battery potential of technology applied to power grid;2013-2016, the titanium has to Hawaii natural energy institute sales the three sets of used to smooth the new energy power generation and FM Titanium acid lithium battery energy storage system, a total of 4 mw / 1 MWH, during this period to vestas delivered 1 mw / 250 KWH of lithium titanate frequency modulation system, and put into operation in 2014.Again to TSK sales in the same year, a set of 2 mw / 397 KWH energy storage system, put into operation in 2015.

Is not hard to find, the demonstration projects, the scale is not large, is a single set of system 1 mw to 2 mw. Through the project demonstrates the titanium and silver ability of the new energy. At the same time, also welcomed many challenges: first, how to make the economical efficiency of energy storage system; Second, Mr. Titanium system design life of lithium titanate is 20 to 25 years, the earliest a distance it is nine years, how to prove to the customer really such a long life? Therefore, in the process of the project from design to delivery of the experience also developed a simulation platform software -- thermal management system, the titanium in thermal management superior technical strength, the safety of the lithium titanate energy storage system, life, reliability and comprehensive performance plays an important role. According to the north star power grid, in order to make the temperature of the battery the best state, 24 v / 70 ah module between every two batteries are designed for conducting strip, in order to further increase the cooling performance, 36 v module than 48 v module reduced the number of batteries, also increased the thickness of plates to improve the thermal conductivity of thermal conductivity.

"For the international market, we escaped from the international market for a period of time, but we have been in the reserves, energy storage as the project delivery, silver long new energy from 2010 to 2012, completed acquisition of the titanium companies in the United States has 100% this year full control of the titanium companies in the United States, now silver long new energy focus on electric vehicle, profit growth quickly. At the same time, we return to the international energy storage market again." Senior sales director Li Iiing said.

ALTI - ESS container storage system to improve operation efficiency to reduce carbon emissions

In the past on dc international summit and exhibition 2018, silver long new energy prepared, carry ALTI - ESS front-loaded container storage system.

Advanced energy storage technology is involved in promoting the innovation of power grid, the grid more efficient way of dealing with power generation, power and policy changes. According to Polaris network understanding, ALTI - ESS container is a cleaner, more efficient energy storage system, operation efficiency and stability of power grid management system is a set of universal, intelligent energy management platform, power can be extended. lithium titanate based on advanced technology, ALTI - ESS release or absorption power by power grid, response frequency fluctuations in milliseconds, so as to improve the utilization rate of equipment and production capacity, improve operational efficiency, reduce carbon emissions.

According to understand, ALTI - ESS in the United States has more than 8-year-experience in the commercial operation of FM, system after the installation is complete, and one at the end of the year and the end of the second will do the test, accord with the battery performance and life expectancy of more than 25 years.

Although the others on the market lithium battery technology could reach the same charge and discharge rate, but it lacks can provide efficient solutions for long life cycle. Only the extension of the titanium is in power grid control requirements within the life cycle of 6 c ratio.

A new generation of multiple advantages ALTI - ESS energy storage systems compared with the previous generation of products in the same standard, 40 feet ocean container to keep other performance under the premise of lithium titanate advantage, at a lower cost, energy increased 2.5 times.

"Because of the high cost of energy storage, so we're going to find suitable for the application of lithium titanate scene, need some high power, higher requirements for safety, life of some application scenarios that I can."Jiing li said, "is a KEMA for power grid and energy field testing and validation of independent consulting company, the company was verified the titanium technology, rapid response and the round-trip efficiency more than 90% of senior titanate lithium battery energy storage system."

Over the years, silver long new energy is committed to upgrading the lithium titanate battery energy density. With focus on research and development and technology promotion, the company research and development of the fourth generation of high energy density titanium silver long battery, than on a few generation product, life, capacity, maximum power, stability, resistance and so on have very big improvement.

Aiming at the problem of low energy density of short board, Lee Jiing said: "the domestic energy storage dozens mw project, we still haven't participate in, but the future will consider large-scale projects with high energy density of electrochemical energy storage do together, play lithium titanate high power on the front end fast response, energy storage support behind by high energy battery, now also in developing this solution. We are confident that this year will be rolled out in the global and domestic markets."

Adhere to the innovation driven development, constantly improve products and services, silver long new energy will continue to work in the field of energy storage, for our country's new energy to make greater contribution to the development of enterprise.
