Samsung SDI demanded on Monday the revision of the article "Samsung SDI 's pride in secondary battery was hurt" recently published by Korea IT Times.
The battery maker's official said, "(SDI)'s sales dependence on Samsung Electronics is not high. It is also considered a top player in the global ESS market."
The firm may have reduced its dependence on Samsung Electronics with more than 50 percent market share in the small secondary battery for gearing tools and golf carts besides smartphones, but it was not able to smartly deal with the shift in large secondary batteries.
Analysts pointed out that the earnings shock of the firm in the fourth quarter was caused by weak sales of Samsung Electronics' IM (Information technology & Mobile communications) division, which means it is not convincing that Samsung SDI reduced its dependence on Samsung Electronics.
The battery maker should more focus on technology development and marketing activities through overhauling of its business, according to industry watchers.
SDI’s claim that the firm is the global No.1 player is not also persuasive. According to B3, research firm specializing in secondary battery, Samsung SDI ranked first in 2014 by supplying 183.7MWh in the ESS market with 23.6 percent market share. At the time, its rival LG Chem came in second with 20 percent market share by supplying 155.6MWh in the market.
However, LG Chem set a new world record in December by signing a deal with the world's largest ESS firm AES Energy Storage to supply first-ever 1GWh. 1GWh is equivalent to 1000MWh. Samsung SDI's 183.7MWh is less than one fifth of the volume LG Chem is set to provide.
Although it cannot be directly compared to LG Chem's long-term deal to supply by 2020, many industry watchers said LG Chem already took the leadership in the ESS market.
In terms of comprehensive evaluation too, LG is ahead of Samsung. According to the global battery business report published by market research firm Navigant Research, LG Chem came in first in the ESS market. Samsung SDI came in second last year and never came in first in the report.
Navigant Research evaluates the company's vision and strategy, system integration, production strategy, safety processing technology, productivity and cost competitiveness.
“As the ESS market belongs to the emerging market, users still require proven products based on high technology, system safety and sales history," an industry insider said.
