Li-ion batteries also have low self-discharge rate of around 1.5-2% per month. This is an advantage over both Ni-Cd and Ni-MH, which display this effect. Li-ion batteries have no memory effect, a detrimental process where repeated partial discharge/charge cycles can cause a battery to ‘remember’ a lower capacity. This means that they can deliver large amounts of current for high-power applications, which has Li-ion batteries are also comparatively low maintenance, and do not require scheduled cycling to maintain their battery life. In addition, Li-ion battery cells can deliver up to 3.6 Volts, 3 times higher than technologies such as Ni-Cd or Ni-MH. They have one of the highest energy densities of any battery technology today (100-265 Wh/kg or 250-670 Wh/L). Li-ion batteries typically use ether (a class of organic compounds) as an electrolyte.Ĭompared to the other high-quality rechargeable battery technologies (nickel-cadmium or nickel-metal-hydride), Li-ion batteries have a number of advantages. Other cathode materials include lithium manganese oxide (used in hybrid electric and electric automobiles) and lithium iron phosphate. The most common combination is that of lithium cobalt oxide (cathode) and graphite (anode), which is most commonly found in portable electronic devices such as cellphones and laptops. Li-ion batteries can use a number of different materials as electrodes. In part because of lithium’s small size (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume. The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize. During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. NASDAQ does not use this value to determine compliance with the listing requirements.A lithium-ion (Li-ion) battery is an advanced battery technology that uses lithium ions as a key component of its electrochemistry. "Market Cap" is derived from the last sale price for the displayed class of listed securities and the total number of shares outstanding for both listed and unlisted securities (as applicable). It does not include securities convertible into the common equity securities. Market Cap (Capitalization) is a measure of the estimated value of the common equity securities of the company or their equivalent. Register for your free account today at. Data Link's cloud-based technology platform allows you to search, discover and access data and analytics for seamless integration via cloud APIs. Real-time Data is provided using Nasdaq Last Sale Dataĭata provided by Nasdaq Data Link, a premier source for financial, economic and alternative datasets.Investors who anticipate trading during these times are strongly advised to use limit orders. Stock prices may also move more quickly in this environment. Participation from Market Makers and ECNs is strictly voluntary and as a result, these sessions may offer less liquidity and inferior prices. ET) and the After Hours Market (4:00-8:00 p.m. Investors may trade in the Pre-Market (4:00-9:30 a.m. This data feed is available via Nasdaq Data Link APIs to learn more about subscribing, visit Nasdaq Data Link's products page. Real-time bid and ask information is powered by Nasdaq Basic, a premier market data solution. You can use the bid-ask spread to determine whether to place a market order or limit order when trading, helping you to optimize your price and have a successful order execution. In contrast, a larger spread suggests lower liquidity, as there are fewer investors willing to negotiate. Often, a smaller spread suggests higher liquidity, meaning more buyers and sellers in the market are willing to negotiate. The bid-ask spread can indicate a stock’s liquidity, which is how easy it is to buy and sell in the marketplace. The data displayed in the quote bar updates every 3 seconds allowing you to monitor prices in real-time. The bid size displays the total amount of desired shares to buy at that price, and the ask size is the number of shares offered for sale at that price. The numbers next to the bid/ask are the “ size”. amount that a seller is currently willing to sell. The bid is the highest amount that a buyer is currently willing to pay, whereas the ask is the lowest The bid & ask refers to the price that an investor is willing to buy or sell a stock.
