On November 12, the 9th China International Solar Storage and Charging Conference was grandly held at the Shanghai Jiading Sheraton Hotel. The conference brought together many companies in the industry to participate in the event, and invited academicians and experts, leaders of upstream and downstream companies in the industrial chain, and market product and technology pioneers to gather together and exchange ideas. Ritar Group was invited to attend and deliver a speech at the main forum, and exchanged views with industry insiders on the development of new energy and safe energy storage. At the same time, Ritar won the two honorary awards of "2022 Best Energy Storage Battery Supplier" and "2022 Best Energy Storage Demonstration Project" for its advanced "acid-free solid-state battery" energy storage system solutions and excellent energy storage project application experience.

Hu Jiada, Chairman of Ritar Group, delivered a keynote speech entitled "Necessity of safe energy storage and development trend of new energy"

Hu Jiada, Chairman of Ritar International Group, delivered a wonderful keynote speech at the main forum of the plenary session, "Necessity of Safe Energy Storage and Development Trend of New Energy". Hu Jiada believes that under the background of the dual-carbon strategic goal, the new energy industry has shown explosive growth, which has brought unprecedented development opportunities to the energy storage industry: First, the proportion of renewable energy power generation has increased, and the difficulty of power grid in transmission and distribution, volatility regulation, etc. has increased; second, due to the limited power grid absorption, the wind and solar power abandonment rate may rebound due to the rapid increase in photovoltaic and wind power; third, the number of new energy vehicles has increased, and the rapid penetration of fast charging stations has increased the control difficulty and instability risk of the power grid; these high proportions of renewable energy have spawned huge energy storage needs, forming a large market of tens of trillions of yuan a year.

Hu Jiada pointed out that the current energy storage technology is developing in a diversified way, electrochemical energy storage has a prominent cost-effectiveness, great commercial prospects, and is the mainstream direction of the industry. With the rapid development of the energy storage industry, the fire and explosion of electrochemical energy storage batteries have become a pain point in the industry, so safe energy storage is imperative.

In the field of electrochemical energy storage, Ritar's energy storage system solutions with acid-free solid-state batteries (OPzV solid-state lead batteries) as the core have been widely used at home and abroad. Hu Jiada said that it is necessary to evaluate energy storage batteries from four dimensions: "safety dimension, environmental protection dimension, resource sustainability dimension, and economic dimension", and this is exactly the advantage of Ritar's acid-free solid-state battery energy storage system solution.

Ritar acid-free solid-state battery energy storage system solution

1. Acid-free solid-state batteries are safe and worry-free

The Ritar energy storage system solution is designed with acid-free solid-state batteries, which are tubular columnar structures (academic name OPzV solid-state lead battery, detailed battery technical parameters can be found on Baidu Encyclopedia), and are the leaders in electrochemical energy storage and the best solid-state battery technology in the world. It has the advantages of long design life, stable performance, and high reliability, and can be widely used in various medium and large energy storage, power, communications, petrochemicals, rail transportation, solar energy, wind energy and other new energy system fields.

The main features of its battery are as follows：

Electrolyte: Pure imported nano-scale gas-phase silica solid electrolyte is used. The solid electrolyte will not catch fire or explode, there is no sulfuric acid liquid, and there is no risk of leakage.

2. Flexible design of “battery wall”

The "battery wall" concept allows for flexible design of energy storage power stations based on site conditions.

The "battery wall" is one of the multiple scenarios that the Ritar Group has developed for user-side energy storage in conjunction with the dual-carbon strategy. The battery wall built with acid-free solid-state batteries effectively solves the problems of indoor energy storage safety and space occupation. The battery wall can be flexibly built inside buildings and on walls and other sites to achieve a perfect fit. While ensuring high safety and reliability, it achieves the smallest footprint and better utilizes various existing building conditions to achieve green electricity.

3. Ultra-long design life and perfect battery management system

The energy storage power station has a design life of 25 years and a battery cycle life of 5,500 times. Under the same conditions, its cycle life is about 4-5 times longer than that of conventional batteries.

The energy storage system is equipped with a complete battery management system, which adopts a three-level management architecture, including battery level, battery pack level and system level, to achieve comprehensive control, management and protection of the battery system, ensure the safe and stable operation of the battery system, and realize unmanned and online control, presenting the relevant operation status of the energy storage power station in real time.

Star-studded awards ceremony, Ritar wins another honor and demonstrates its strength

At the Starlight Awards Ceremony that night, colleagues from the industry gathered together to celebrate the event. Ritar once again won the two honorary awards of "2022 Best Energy Storage Battery Supplier" and "2022 Best Energy Storage Demonstration Project" for its advanced "acid-free solid-state battery" energy storage system solutions and excellent energy storage project application experience.
