China develops lithium battery twice as powerful as Tesla's advanced cell
Chinese scientists have developed a breakthrough lithium metal battery that stores twice as much energy as Tesla's most advanced electric vehicle battery Researchers at Tianjin University have made a battery with an energy density of over 600 watt-hours per kilogram. Energy density – the amount of energy stored per unit mass – determines how much power is stored in a device. The greater the energy density, the smaller and lighter the battery can be. Lithium metal batteries are known to have a higher theoretical energy density than conventional lithium ion batteries and are considered a promising next-generation solution. The energy density achieved in the latest battery is twice that of the Tesla cell's 300 watt-hours per kg and far more than the BYD Blade's 150 watt-hours per kg. The findings, published in the journal Nature on Wednesday, represent a 200-300 per cent improvement over current lithium metal battery energy density and endurance. Lithium battery electrolytes typically rely on solvation structures, orderly arrangements of solvent molecules around lithium ions, which can also create barriers to performance. While this arrangement stabilises lithium ions, it impedes rapid and uniform lithium deposition during charging and use. Such structures can limit a battery's longevity, safety and energy density, posing a significant challenge. 'The practical applications of LMBs are constrained by current electrolyte designs that inherently rely on dominant solvation structures,' researchers said in the study. For the new battery, researchers reimagined the solvation environment of lithium ions, overcoming the limitations of current electrolyte designs. They developed a new 'delocalised electrolyte' with a more disordered, delocalised solvation microenvironment, reducing barriers to ion transport and allowing enhanced stability – two critical factors behind battery performance and cycle life. The new electrolyte design has a more heterogeneous environment that allows for more fluid lithium-ion dynamics. When scientists tested this electrolyte in commonly used high-capacity lithium metal pouch cells, it delivered an unprecedented energy density of 604.2 watt-hours per kg, while maintaining stable cycling over 100 cycles. This energy density surpasses Beijing's goal under the 'Made in China 2025' plan for electric vehicle batteries to reach 400 watt-hours per kg. Researchers have already deployed the new technology for the production of high-energy lithium metal batteries for drones.

Scientists make lithium battery breakthrough, doubling energy density
Chinese scientists at Tianjin University have developed a groundbreaking lithium metal battery. The new battery achieves an energy density of over 600 watt-hours per kilogram, which is double that of Tesla 's most advanced electric vehicle battery. This innovation represents a 200-300 per cent improvement in energy density and endurance compared to current lithium metal battery technology. The breakthrough was achieved by developing a 'delocalised electrolyte' that enhances stability and ion transport within the battery. The technology has already been implemented in high-energy lithium metal batteries for drones and exceeds China's 2025 energy density targets for electric vehicle batteries.

Strength Seen in Enovix Corporation (ENVX): Can Its 20.8% Jump Turn into More Strength?
Enovix Corporation ENVX shares soared 20.8% in the last trading session to close at $10.53. The move was backed by solid volume with far more shares changing hands than in a normal session. This compares to the stock's 5.1% gain over the past four weeks. ENVX is benefiting from its unique 100% active silicon anode architecture, enabling superior energy density, fast charging, and competitive performance across multiple markets like smartphones, smart glasses, and defense applications. This company is expected to post quarterly loss of $0.17 per share in its upcoming report, which represents a year-over-year change of -21.4%. Revenues are expected to be $5.62 million, up 49.1% from the year-ago quarter. Earnings and revenue growth expectations certainly give a good sense of the potential strength in a stock, but empirical research shows that trends in earnings estimate revisions are strongly correlated with near-term stock price movements. For Enovix Corporation, the consensus EPS estimate for the quarter has remained unchanged over the last 30 days. And a stock's price usually doesn't keep moving higher in the absence of any trend in earnings estimate revisions. So, make sure to keep an eye on ENVX going forward to see if this recent jump can turn into more strength down the road. The stock currently carries a Zacks Rank #3 (Hold).

Nascent Materials emerges from stealth to make LFP batteries better and cheaper
Lithium-ion batteries have dropped in cost by 75% over the past decade, a marvel of research and development that isn't the result of a singular breakthrough but of myriad incremental improvements. Few know that better than Chaitanya Sharma, founder of the stealthy Nascent Materials. Sharma spent a little over two years working at Tesla's Gigafactory in Nevada and another two leading iM3NY, a lithium-ion manufacturer in New York. Since leaving iM3NY in November 2023, he's been working on a new way to process cathode materials for lithium-ion batteries — one of those small improvements that promises to continue driving down costs. Nascent's new process could improve energy density of the cathode by up to 12% while costing 30% less to make. 'In my mind, developing a new exotic chemistry is not really the way that I want to go,' Sharma told TechCrunch. 'I want to develop new ways of making material.' Sharma's manufacturing-focused approach has attracted early investment. Nascent recently raised $2.3 million in a seed round led by SOSV, the company exclusively told TechCrunch. The New Jersey Innovation Evergreen Fund and UM6P Ventures also participated. The startup's initial focus is on making lithium-ion-phosphate (LFP) and lithium-manganese-iron-phosphate, (LMFP), two cathode materials that have gained favor among automakers and data center operators. Recent improvements have brought LFP energy density closer to higher-end nickel- and cobalt-based chemistries but at much lower costs. But there's still room for improvement. Sharma said that obtaining materials with consistent quality was a challenge at iM3NY, one that contributed to the company's Chapter 11 bankruptcy filing in January.

Boston, MA | REGISTER NOW The problem stems from supply chain inequities. Large players like Tesla's Gigafactory, which it operates in partnership with Panasonic, tend to get more consistent material, Sharma said. 'The small players, which, by the way, spend $100 million to $200 million on their factories as well, they get the outlier material.' 'That really became the reason why I wanted to launch Nascent Materials — because I want to make sure that I provide consistent materials to all customers,' Sharma said. Cathode material tends to come in powders, and while it might look consistent to the naked eye, slight variations in the grains can have an outsized impact on the final result. Sharma said Nascent has developed a process that uses less energy while also promising to create particles that are more consistently sized and shaped. That allows the material to be packed more tightly, improving energy density. The process offers additional supply chain advantages. It can also use lower-purity raw materials, he said, opening up more domestic supplies. While Nascent is focused on LFP and LMFP today, Sharma said the company plans to expand to other chemistries, including nickel-manganese-cobalt (NMC) and lithium-manganese-rich (LMR), a relatively new chemistry that GM will introduce in 2028. That domestic focus addresses a critical industry dependency. Today, the vast majority of cathode material is made in China. 'How can I not rely on China for them?' Sharma said. 'That's really what we are focused on — simplifying the supply chain so we can utilize local raw materials, so that drives the cost down.'
