Steroids that contain a 3-hydroxyl group (3-OH steroids) are widely distributed in nature. During analysis with ESI-MS, they easily become dehydrated while in the protonated form, resulting in the production of several precursor ions and leading to low sensitivity of detection. To address this analytical challenge, here, we developed a method for the quantitation of 3-OH steroids by LC-MS/MS coupled with post-column addition of lithium (Li) ions to the mobile phase. The Li ion has a high affinity for the keto group of steroids, stabilizing their structures during ionization and permitting detection of analytes exclusively as the lithiated form. This not only improved the intensities of the precursor ions, but also promoted the formation of typical lithiated fragment ions. This improvement made the quantitation by multiple reaction monitoring more sensitive and reliable, as evidenced by 1.53–188 times enhanced detection sensitivity of 13 steroids that contained at least one keto and two hydroxyl groups or one keto and one 5-olefinic double bond, among 16 different 3-OH steroids. We deployed our newly developed method for profiling steroids in mouse brain tissue and identified six steroids in one tissue sample. Among these, 16-hydroxyestrone, tetrahydrocorticosterone, and 17α-hydroxypregnenolone were detected for the first time in the mouse brain. In summary, the method described here enables the detection of lithiated steroids by LC-MS/MS, including three 3-OH steroids not previously reported in the mouse brain. We anticipate that this new method may allow the determination of 3-OH steroids in different brain regions.

Strictly-defined pediatric bipolar I disorder (BP-I) is a serious condition. Although lithium is a benchmark treatment and has shown effectiveness in adults for decades, no definitive efficacy or long-term safety studies had been performed in pediatric patients with BP-I.

This study provides evidence to support the efficacy of lithium in the acute treatment of youths with BP-I who are currently in a manic or mixed state. Lithium had an adverse effect profile that was acceptable for most patients. (Read the full article)

2018 was another defining year for the lithium supply chain as the global population continued to make remarkable strides towards the implementation of clean energy and transportation. Although the clean energy and transportation industries are only in their early days, it has become apparent that renewables and electrification of transportation are an irreversible trend, one that has begun to disrupt many established industries.

Clean-energy visionaries have long argued that the world needs a better battery capable of selling skeptical consumers on electric cars and running the grid on renewable power. And yet the battery of the future—at least for the coming decade—will almost certainly be the battery of the past.

China is mulling a policy to provide a subsidy for lithium batteries deployed in electric vehicles. This new favorable policy is expected to propel the development of the country’s electric vehicle sector. China has existing subsidy policies for the sector, but higher prices for the parts used in electric vehicles, in particular lithium batteries, prevent many consumers from purchasing the vehicles.

Demand for lithium is growing very rapidly thanks to portable electronics and electric vehicles. What if we could get a lot of lithium cheaply, without building new mines?

A new way to see inside batteries in real time as they go through charging cycles could help prevent battery fires and increase battery lifespans

Lithium continued the downtrend to a fresh record low on a spot price basis in May, trading below 44,000 yuan per tonne as demand remained subdued in China’s lithium market even after the country’s authorities allowed the domestic business to return to work. Still, demand for lithium is expected to pick-up in the second half of 2020 due to the continued widespread adoption of electric vehicles. On the supply side, forecast that new supply from Argentina, Australia, and Chile, could add 500,000 tonnes of lithium to the market per year by 2025. Lithium reached an all time high of 171000 yuan per metric tonne in October of 2017, according to spot prices for lithium carbonate traded in China. Trading Economics provides Lithium pricing based on spot prices for Lithium Carbonate, 99.5% Li2CO3 min, battery grade, traded in China. Lithium is a silver-white light metal. Lithium hydroxide is used in batteries for electrical vehicles and mobile phones. Lithium hydroxide is produced from a chemical reaction between lithium carbonate and calcium hydroxide. The biggest lithium producers are Australia, Chile, Argentina and China . The largest lithium importers are China, Japan, South Korea and the United States.
