Japan's new energy industry technology focuses on four aspects
Introduction: As a powerhouse in automobile manufacturing and a powerhouse in the photovoltaic industry, Japan ’s actions in the new energy industry and technology have been receiving worldwide attention. According to recent visits to Japan, Sharp (Solar), Toyota (Hybrid), Tokuyama (Japan ’s largest polysilicon plant), Fuji Electric (Flexible Film), Mitsubishi Heavy Industries (Nuclear Power and Clean Combustion) and other companies, Guojin Securities New Energy Industry analyst Zhang Shuai said that Japanese companies are focusing on thin-film batteries, hybrid electric vehicles, nickel-metal hydride batteries, and clean combustion in terms of new energy technologies.

In terms of solar energy, Japanese companies generally focus on thin-film batteries rather than crystalline silicon batteries. Deshan Chemical, which was one of the world's top five most crystalline silicon companies, also placed capacity expansion in Malaysia.
Zhang Shuai said that at present, Japanese companies basically gave up competition with Chinese companies in the field of conventional crystalline silicon batteries, and instead developed their more advantageous thin-film batteries or high-conversion crystalline silicon batteries.
Japanese giants represented by Sharp shifted their newly added huge production capacity to thin-film batteries. They plan to expand production to 1200MW by 2012, and claim that the stack conversion rate is greater than 10%; ShowaShell uses its own process to produce CIS batteries than the current mainstream. Of CIGS batteries have eliminated the CDS buffer layer, avoiding the potential pollution of heavy metal cadmium; Fuji Electric is unique in the field of flexible thin-film batteries. The company plans to extend the advantage of flexible thin-film moldability in the field of photovoltaic building materials; Sanyo Electric is taking On the road to high-efficiency crystalline silicon cells, from the perspective of sales in the European market, Sanyo's conversion rate and selling price are far ahead of other competitors.
In the battle between EV (electric vehicle) and HEV (hybrid electric vehicle), Toyota clearly supports HEV. In terms of the choice of nickel-metal hydride batteries and lithium batteries, Toyota believes that nickel-metal hydride is the best balanced choice at present. The reason for supporting hybrid vehicles instead of pure electric vehicles comes from a comprehensive comparison of battery technology, cost, range, metal consumption, etc. Toyota believes that hybrid vehicles are currently the best choice. Pure electric vehicles have excellent indicators but obviously lack economics; The same is true for the choice of battery. Although the technical indicators of lithium batteries are better than nickel-metal hydride batteries, the current use of nickel-metal hydride batteries for hybrid vehicles as short-distance vehicles is sufficient. Lithium batteries are not necessary.
In the exchange with Mitsubishi Heavy Industries, the focus was on clean combustion and nuclear power technology. The company not only produces military products such as fighter tanks and launch vehicles for the Japanese army, but also is an important player in the field of power generation equipment worldwide. Mitsubishi Heavy Industries believes that clean combustion and CCS (carbon capture and storage) are its core competitive business segments, and its IGCC (coal-fired) or GTCC (gas-fired) combination can achieve better emission reduction effects; in addition, its pressurized water After years of safe operation, the reactor has never suffered a serious accident, which is the biggest competitive advantage.
