Lithium-air, or lithium-oxygen, has been touted as the ultimate battery technology, because its theoretical energy density is ten times that of current lithium-ion solutions. However, scientists have struggled to overcome major challenges with the technology. The batteries waste a lot of energy as heat, degrade relatively quickly, and often require extra components to pump oxygen… Read more »

Elon Musk debunks scare stories about a shortage of lithium
Elon Musk and JB Straubel covered a lot of ground in a nearly-three-hour performance at Tesla’s 2016 annual shareholder meeting. They recapped the history of the company, explained why Supercharging will not be free for Model 3 buyers, and discussed their plans to remake the auto production process. They also made some very interesting remarks… Read more »
Two-level cathode structure improves battery performance
As the search for a better battery grinds on, a lot of the attention is focused on potential cathode materials. Nickel is one possibility that shows a lot of promise – its drawback is that it is unstable and tends to have destructive reactions with the electrolyte. Now a team of scientists from the Brookhaven… Read more »
New electrolyte for solid-state batteries combines polymer and glass
Scientists at the DOE’s Lawrence Berkeley National Laboratory have developed a novel electrolyte that addresses many of the problems of solid electrolytes by combining the two primary types – polymer and glass. There are two kinds of solid electrolytes – polymer and glass or ceramic – and each has its own set of challenges. Polymer… Read more »
Bombardier battery-powered tram makes record test run
Bombardier Transportation has successfully completed a 26-mile catenary-free test run in the German city of Mannheim using a tram, powered by Bombardier’s PRIMOVE battery and MITRAC (Modular Integrated TRACtion) system. The PRIMOVE system features batteries provided by the German firm AKASOL, and use nickel manganese cobalt (NMC) Li-ion cells. A thermal conditioning unit maintains the… Read more »
Is Nissan teasing details of 2nd generation LEAF?
Nissan recently invited a small group of journalists to its Advanced Technology Center in Atsugi, near Tokyo, ostensibly to show them the IDS concept vehicle now on display at the Tokyo Motor Show. However, Bertel Schmitt, an old Japan hand, soon surmised that the reporters were looking at “the future Nissan LEAF in drag,” and… Read more »
Analyst: Tesla will reduce battery cost 50% by 2020
There’s a lot of future potential baked into Tesla’s stock price, but many stock pundits believe it’s headed even higher. Jefferies analyst Dan Dolev recently raised his price target for TSLA to $365.00, based on his belief that the company will be successful at lowering battery costs, and that this will improve its gross margins….

Freescale introduces new lithium-ion battery cell controller
Lithium-ion chemistries are increasingly replacing lead-acid automotive batteries, especially in start-stop and energy recuperation systems, and they are even making inroads into starter battery applications. Electronics such as Freescale Semiconductor’s battery cell controllers are used to manage risks such as overcharge, overheating and internal short circuits. Now Freescale has introduced the MC33772 3- to 6-cell… Read more »
3M licenses NMC patents to LG Chem
3M and LG Chem have formed a patent license agreement to allow the Korean battery-maker to use 3M’s formulation of nickel manganese cobalt oxide (NMC) cathode materials in lithium-ion batteries. NMC, valued for its balance of power, energy, thermal stability and low cost, has been the subject of some rivalry and at least one lawsuit…. Read more »
Samsung says it can immediately double capacity of Li-ion batteries
Samsung Electronics has developed a silicon carbide-free graphene coating that it says could immediately double the capacity of lithium-ion batteries. That would be an impressive feat indeed, considering that capacity has increased only twofold since Li-ion batteries were first commercialized in 1991. Many researchers are investigating the potential of silicon as an anode material, but… Read more »
