Energy Storage

Previously known for its automotive activity, CATL is turning to another promising sector to generate demand for its battery cells. With the first few hundred thousand Japanese solar households seeing their 10-year FIT contracts expire, demand for small scale storage is on the rise

Batteries of the type have traditionally been used for long-duration storage applications. Now though, it seems vanadium is making an entry into the fast-paced world of ancillary grid services.

Corporations are buying up batteries and investing in their companies like it’s going out of style.

Elon Musk’s EV and energy company is becoming increasingly irrelevant in the rooftop solar market, but battery sales are booming.

Rather than helping electric vehicle take-up by driving down costs to parity with traditional engines, the low price of nickel at the moment is deterring investors and could cause a supply shortage that holds back electromobility in a few years’ time.

Scientists at the University of California, Santa Barbara who are working with sodium-ion batteries have found that the unintended presence of hydrogen is to blame for many of the technology’s shortcomings in terms of degradation and performance loss. Keeping hydrogen out of the materials throughout production could allow sodium-ion batteries to achieve performance levels competing with their lithium-ion counterparts.

… and it will be quite an effort. The U.K.’s grid operator, National Grid, released a new report on possible energy system transformation pathways, amidst growing public concern over climate change. Ramping carbon emissions reduction targets up from 80% to 100% prompts technical challenges. These can be overcome but will require full alignment of policy effort and individual awareness and decision making.

Japanese materials company Toray has announced plans to open a facility for manufacturing battery separator films for use in lithium-ion batteries. The factory is expected to begin operations in July 2021 and will increase Toray’s production material for the component by around 20%.

While it is often stated only 5% of lithium-ion batteries are recycled, a review of research into the second life and recycling of lithium-ion batteries suggests that is a gross understatement. A new study found almost 100,000 tons of waste batteries were recycled last year – about half of what reached end-of-life.

The car will be road tested at Toyota City in Japan. Solar charging technology for the vehicle will then be further optimized before the vehicle goes on sale.
