Starting in May, the Ministry of Economy, Trade and Industry will work with companies to promote the development of high-efficiency all-solid batteries, according to Japanese media. To this end, the Ministry of Economy, Trade and Industry of Japan will invest 1.6 billion yen in the Institute of Technology Research, lithium battery Materials Evaluation Research Center(LIBTEC). In addition to material manufacturers such as Toray, Xuhuacheng, Mitsui Chemical, and Mitsubishi Chemical, large auto manufacturers such as Toyota, Honda, and Nissan, as well as battery suppliers such as Matsushita and GS Yuasa, will also join LIBTEC's research and development work.
All-solid battery patents lead in Japan
One of the aims of the Japanese government's efforts to increase the development of all-solid batteries is to regain market share in the battery sector. Japanese companies are in the forefront of the car battery industry, accounting for 70 per cent of the global market in 2013, according to the Japan Economic News. However, Chinese and South Korean companies are catching up fast, with Chinese companies with a market share of only 3 % in 2013 having expanded to 26 % by 2016, while Japanese companies fell to 41 %.
Full solid battery? Japanese government enterprise group brush
Jiyezhang, known as the "father of lithium batteries," believes that the closest to practicality of the new generation of batteries is all-solid batteries. According to the Journal Industry News, patents for all-solid batteries have continued to increase since 2006, and Japan accounted for 54 % of global all-solid cell-related patents from 2012 to 2014.
His Government planned to start with technology development and standard-setting. At present, the company with the largest number of patents for all-solid batteries is Toyota Motor Co., which plans to commercialize all-solid batteries in 2022.
Last October, Toyota announced that it had invested more than 200 people to accelerate the development of solid-state battery technology. In December, Toyota and Panasonic jointly announced that they were exploring cooperation on Square vehicle-mounted batteries. In addition, the two sides also want to jointly develop all-solid batteries to promote the popularity of electric vehicles through advanced battery technology.
In an interview with foreign media in March, Jilesi?nuomande, the head of Renault Group's electric vehicle business, revealed that the Renault-Nissan Mitsubishi alliance is working on the development of all-solid battery technology. The all-solid battery is a new hope for the automotive industry, says Norman, mainly for long-running electric vehicles. "This technology has a huge advantage over current lithium-ion batteries in terms of cost, density and thermal stability. He added: "Although there are still many challenges, we have made very good progress. The goal is to bring it to the market by 2030, if possible as early as 2025. "
In addition to auto manufacturers and battery manufacturers, material manufacturers such as Mitsubishi Gas Chemical, Toray, Sumitomo Chemical are also optimistic about the market prospects of all-solid batteries and are accelerating the development of related materials. Mitsubishi Gas Chemistry aims to develop solid electrolytes for all-solid batteries by 2020 in order to bring a new generation of battery materials to market as soon as possible.
Still, there are plenty of industries that are wary of all-solid batteries. Although solid state batteries do work in the lab, if you make them bigger and put them in cars, you still can't guarantee mileage, safety and cost, said Takao Sasaki, Nissan's senior vice president of research and advanced engineering. More breakthroughs are needed.
Promoting the development of international standards
In order to master the global dominance of in-vehicle all-solid batteries and improve the competitiveness of Japanese battery manufacturers, the Ministry of Economy, Trade and Industry is considering applying to the International Electrotechnical Commission(IEC) to promote the development of international standards. In April this year, the Ministry of Economy, Trade and Industry of Japan and the Japan Agency for the Comprehensive Development of New Energy Industry(NEDO) announced that the joint development of an international standardization strategy for in-vehicle all-solid lithium batteries would be limited to 2022. Develop a test evaluation method for all-solid lithium batteries that reflect international standards and specifications.
The work to be done includes: durability test data of all-solid lithium batteries, deterioration mechanism and analysis of deterioration phenomenon, deterioration of battery units and constituent materials, parts and components, etc.. In addition, it is necessary to develop an accelerated test method that can predict the long-term durability of all-solid batteries in the short term.
In order to achieve mass production of all-solid batteries, in addition to ensuring safety, standard test evaluation methods are indispensable. In Japan, LIBTEC is actively conducting research in this area. The goal of the Japanese Ministry of Economy, Trade and Industry is to achieve the commercialization of all-solid lithium batteries in the 1920s.
